Lotus are extremely viable and can be planted in ponds, ditches, lakes, river basins, lowlands and rice fields. The soil is based on the presence of organically rich clay. Water canals, lakes and estuaries require slow, low and slow currents and water depths of no more than 1. 2 to 1. 5 metres. Lowlands and rice fields are planted in chains that require water, adequate sunlight and easy drainage. And plant before planting the field to prevent it from leaking. Deep tiller, chubby, rupine. In order to feed fish, “back-to-back” deep trenches should be dug around the field, which are 3-4 metres wide and 1-1. 5 metres deep, with a height of 0. 5 metres wide and a height of 1. 5 metres high and a width of 2 metres wide, to fill the water environment in which the fish grow, and with which the lichen can be connected or fed, to increase economic returns. Rice stings, one way of doing so, use both pre-maturized varieties. The yangtze river basin lumbers during the period between ching ming and the rain, before the autumn, and after the harvest, the rice is grown in two evenings. Another approach is two and one rice, which is a form of cultivation in the south china. The first was early planting in the spring, and the second was planting in mid-june, and the third in late july and early august. The yangtze river basin is connected with white water. The first year is clear and the rain drains from the valley are pre-cooked, the pool is surrounded by seedlings, and before the fall harvests after that, seedlings were planted in the ponds, which were harvested in the autumn of the year, and white root in the winter and summer in the summer of the second year. The method used to interact with the pelicans is to plant them during the period between the dawn and the rain, to plant them around the field, to harvest them before the autumn, and to plant them after they have gathered them, and to collect them during the period between the whites and the fall, to remove the roots and then replant them. The method of dealing with aunts and aunts is to plant them between the first year and the summer, until the second year of spring, when they are collected, and when they are harvested in early autumn.
Two for the good species
Depending on the size of the plot, soil, water depth, mouths, etc., a variety of branches, resistance and quality are selected. General lowlands, rice fields are suitable for shallow water planting; trenches, estuaries, ponds, lakes are suitable for deep water cultivation. The hyenas are proliferating, but they are long-lived and highly variable. They have been condensed during the year, and they are produced in a variety of ways, including matrilineals, hyenas and grandchildren. In general, before planting, the seeding will be dug up from the fields, followed by a selection of two to three knots of a mother's or a child's, which will be thicker and full of buds, and cut to 1. 5 centimetres after *. It is forbidden to use hand-to-hands in case of discomfort, and then the mud is poured into the hole to cause decay. In the event that the selected matrilineal is accompanied by a child, the direction in which the child is grown shall be broadly the same, so that the lashes of the fruit that is derived from the planting shall extend in a regular manner. Seeds tend to be dug, chosen, planted, and if they cannot be planted on the day, water should be sprayed to keep them wet and to prevent the dystrophy. Long-distance seeding shall be carried out with care to keep it wet and to protect against injuries. Some areas of the yangtze basin are pre-planted with seed seeding, which avoids premature planting and low water temperatures, leading to a shortage of scavenging plants and increasing their utilization. The method of seeding is to plant the seedlings indoors, up and down the mats with straw, with one to two daily water spills, with a temperature of 20 to 25°c, and in 15 days, 6 to 9 cm in length。
Three
The period of planting in the yangtze river basin is usually from the time of dawn to the time of rain; the period of planting in the south china area can be pre-empted or delayed to the time of summer. Plantation density varies from use to use depending on soil fertility, variety, seed size and harvest time. Early-maturity varieties are generally higher than late-maturity varieties, soil fertility is lower than soil fertility, field yields are more dense than late harvests, and there are more cropping. Medium-fatality rice fields and low-lying fields are grown with a production requirement of between 3 and 45,000 kg per hectare in that year, typically with a distance of 1 to 1. 5 metres and a range of 1. 5 to 2. 0 metres, with a range of 3,700 to 4,500 dens per hectare and with a range of 1 to 2 to 4 knots per den, i. E., 3000 to 4,500 kg for mammoths, cucumbers and grafts, and 1,500 to 2,200 kg for seeding only. Trenches, ponds and lakes are planted with a yield of 1,500 to 2250 kg, if required. In the case of trenches, ponds and lakes, if the harvest is required for the current year, more than 600 seeds should be used per hectare, and if no new crop is collected for the current year, the appropriate amount should be less, usually 3 to 4 plants per lavender, with a combination of size and size. When rice fields and lowlands are planted, seedlings shall first be lined up on the field at the prescribed distance, and shall be set aside at a distance of 1. 0 metres from the field around them, with their heads in the interior, so as not to stretch out the lashes of the late-stage fruit. The field head can be arranged in one direction or in relative rows, and when placed in relative order, the line spacing should be magnified so that the lush can be distributed in the field in a way that avoids congestion. When planted, the head is placed 8 to 10 centimetres deep in the mud, then the knots are drawn to the surface of the water in order to receive sunlight, increase the temperature and promote the growth of the bud. When the ponds and lakes are not planted, each seed can be bundled into a small boat, and people enter the water with their feet to open a ditch at depths of 15 to 20 cm, then they are inserted in a ditch with their feet on the tatters, then they are covered with mud and then marked with straws to facilitate counting and prevent stepping. When planted in windy water, white, grass or grass should be planted at a distance of 2 to 3 metres from the field or the periphery to protect the plant from the wind
4 fertilizer management
Rice fields and low-water pipes should be managed from shallow to deep and then from shallow. Dry field water before planting; water depth 3 to 5 centimetres after planting in order to increase water temperature and germinate; water depth 5 to 10 centimetres before rising leaves; water depths increased to 30 to 60 centimetres after growing plants as temperatures rose; and water levels should be down to 10 to 15 centimetres at the end of the season in order to promote young maturity. The water level before and after pond lichen is moved shall also be as shallow as possible and shall gradually deepen as the leaf and the lashes grow, but * not more than 1 metre. Lake and river basin springs are shallow, suitable for planting and budding, and have to be protected against storm rain and flooding of leafy leaves in the summer, resulting in the death of plantations and reduced yields. The lotus needs a lot of fat, so it should be applied again. Lakes, estuary. The pond sludge is deep and organically high, generally resulting in high fat and high yields. The pond is small and can be applied to composting before planting in the early spring. Lowland and rice fields are growing a lot of fertilizers, and general base fats account for 70 per cent of all fertility and 30 per cent of all fertility. It is applied to the ground as a whole, ranging from 75,000 to 90,000 kg green per hectare or from 2,45,000 kg compost to 450 to 750 kg per hectare per calcium per phosphate. Two fattenings, the first of which took place 20 to 25 days after planting with 1 to 2 leaves, promote the growth of lashes and leaves. In general, 1. 5 to 225,000 kg of manure per hectare or 37,000 to 45,000 kg of green manure should be inserted into the mud. The second fertilizer was applied to human urine in 50 (55 days (pre-summer) days after planting, ranging from 150 to 25,000 kg. Every time it is followed up by fat, it should be put in shallowa water, which can be filled to its original depth three to four days after application. The pursuit of fat cannot take place at noon in the sun. If a person's urine is followed, the water will be poured after the chase in order not to burn the leaves. If organic fertilizer is insufficient, it can also be followed up with appropriate amounts. In order to prevent excessive fertilization, which leads to excessive growth on the ground, there is a need to reduce production by increasing the length of periods of maturation. Lowlands and rice fields can be managed in the fields of weeding, leaf harvesting and shifting in combination with fatting. If, during the summer to the second fertilization run, the aging leaves are removed, they increase the amount of sunlight irradiated in the field and the temperature increases the removed leaves and weeds into the mud for fertilizer. Plantation has entered the field for a long period of time from the summer to the present, and the underground lashes have spread rapidly so that, in order to prevent the run-off of the fields, they are condensed outside the fields and transferred to the fields every one week. And when they turn around, put their hands up and put them in the soil, in case they break. For as long as possible, he will not go out of the field, so that he may not step on his body, break his leaves and cause decay。
5 pest control
The main diseases are atrophy, corruption, folicosis, foliage, black spots, brown spots, etc. These diseases have a significant impact on the yield of the fruit, which is generally reduced by between 20 and 90 per cent and, in serious cases, is not productive. Decay or corruption diseases generally occur in the fields where leaves are poured. In the early stages of the onset of the disease, the lobes turn yellow and produce black spots, and later gradually spread to the centre, turning the leaf into tan, drying up the rolls, and then causing decay, all of the leaves to die, and the lobes fall down. Leavage or foliage occurs mainly on the head of the leaf, as well as on the handle. At first, there were light yellow or brown spots on the face of the leaves, which then gradually expanded and became yellow or dark, and then the whole leaf died. Black spots occur on leaves, when they begin to appear in light brown spots, and then expand to a diameter of 10 to 15 mm, with visible wheeled threads and black molds, while severe leaves die. This is also known as brunette. At the time of the onset of the disease, the leaves were circular, with a diameter of 0. 5 to 8 mm, with a slight rise in the multiple direction of the leaves, while the back was dim, initially light brown, yellow brown, then grey brown, with the edges often bearing about 1 mm of brown wavering. The above-mentioned diseases should be based on an integrated approach to prevention, supported by the principle of drug control. Select to be non-toxic; rotate new tricks, isolated from sick fields; rationalize water fertilization, with attention to the use of nitrogen, phosphorus and potassium; remove strains and eliminate pathogens. Aerobics, polybacteria or tobuzin can be treated with 2 to 3 consecutive sprayings within 10 days of the onset of the disease. The main pests are aphids, subleasing mosquitoes: slashed night moths, moths on the edge of brown and yellow moths. The aphids and subleasing mosquitoes and mosquitoes are highly concentrated and are mainly harmful to capacitors or foliages, from planting to precipice, eating foliage and decomposeing the leaves, which are not free of water and do not harm the opposing leaves. The prevention method can be used to spray 40 per cent of the ointment 1,500 to 2,000 times the fluid, and a small amount of leaf can be removed. Slashed night moths, moths on the edge of lignite and yellow moths: food pests, mainly harmful to the leaves, which, in severe cases, eat into light. Method of prevention: foliage removal; entrapment to insects, which are hunted to insects with black light before moth peaks, using insect light and condensation; and ovary infestation, which is removed hand-to-hand during the plethora of eggs。
6 collection and retention
When the back of the leaves is slightly red, * the early-opening of the poaching of the pellets bends to one side, marking the formation of a new subsurface. Most of the leaves were still green and green. The leaves were removed four to five days before the harvest, which caused the subterranean sector to stop breathing, prompting the recovery of the rusty stains attached to it, the rusty skin, and the ease of washing it to improve its quality. In the yangtze basin, early ripening of varieties occurs mostly in the middle of summer and autumn, when they are tender, have high sugar content and can easily be dug, usually without dry fields and hand-picked. Late or late harvests of well-finished varieties, mostly from white to frost, are well-established, drying up the field some 10 days before digging, whipping through and cross-crowding, in which case the distance between the terminated and later leaves can be presumed to be shallow. The distance between the termination of the leaves and the subsequent transfer of the leaves is so far as to enter deep into the soil, and vice versa. First, they empty the mud beneath them, and then slowly drag it down. It is also possible to take advantage of the features of the navigator channel, which will put the leaves in the water, then find the leaves, break the air, or, if the leaves eject a bubble, which means that the two leaves will be lengthened on a twig, so that they can find the lush whips, and leave three centimetres to be broken before the twilight so that the mud does not pour into the gas hole. The lakes and deep water ponds are often made of iron hooks, then the leaves are removed from the top of the line where the leaves end, and all of them are removed from the top of the line, close to a 2-metre radius of the shore, so that the first knots of the mare can be taken from the middle of the water and the last * * . The production of a field is closely related to the number of years of cultivation, the infertile nature of the field, the density of planting, the maturity of the crop and the management of cultivation. The production of ponds is usually low in the first year, with 4,500 to 7,500 kg per hectare, and 7,500 to 20,000 kg per hectare after the second year, but after five to six years of planting, production has gradually declined and should be replaced. If water fields and lowlands are to achieve a high level of production in the current year, they will need to increase the level of drainage and enhance the management of fertilizers. The soil of the remaining fields* is clayy and excavated before the spring of the second year. It can be found on the basis of money leaves that come out of the water. The species should have their own species characteristics, be organized and grow in the same direction, and then the festival and the hysteria of the hysteria, etc., which, if later reduced to smaller, indicate that the castes have changed and must be phased out. In order to save seed species, it is possible to store them in winter with 2 to 3 knots of larvae or grandkids. This is done by extracting, at the time of digging, the husks and grandchildren, which have the characteristics of their own species, and which are intact, in time for storage in case of freezing or water loss. The size of the pyramid pit, which is dug in a low-water field about 30 cm deep before storage, is determined by the storage stock, the raisins or grandchildren are put into the pit, the soil is filled light and light, the water is poured up, and the planting is taken out in the spring of the second year。
