Pyramid, a more popular banana hybrid plant in recent years, has been the subject of a series of experiments by a number of cooperative enterprises on high-quality, high-yielding pyramid techniques, which have been developed as a set of disease-control plant management techniques that can be used to increase production and productivity。
1. Selection
The golden powder no. 1 is an excellent variety of chalk, which was validated in 2010 through crop varieties in the guangxi autonomous region (cuisuméo 2010005). The fruits are larger, with high edible rates, white fruit, sweet and sweet tastes, high flavours, rich nutrition, more resistant to cold, drought, anti-black star disease, beads and foliage heart disease, good commodities and high market potential. In recent years, in the cities of guangxi naning, chin county, port-of-city, yulin and 100-coloured cities, all of which have grown on a large scale and have grown to the provinces of guangdong, hainan and yunnan, the lowest selling prices are above $4. 0/kg, up to $8. 4/kg, with a value of 10-18,000 per 667 m2 and a high yield。
2. Planning design
Penang selection
Instead of sleeping in the ground, a new crop model is being used to grow a generation of platinum. Selection of water fields above 1 m thick, above 1 m water table, without water, with good weather protection, with plenty of sunlight, easy transportation, and with no crops such as bananas and chalk。
Deep till
Each 667 m2 is spilled into the raw lime 100 to 150 kg to regulate soil ph values, reduce the number of parasites or residues, use machinery to push more than 60 cm deep, improve soil permeability, gas and storage properties, increase crop thickness, bury trees and weeds and crop residues in the pyrotechnic garden and tan more than 20 d。
Land-building
The size and depth of the drain can be determined by the terrain to ensure that the reservoir is quickly eliminated in a short period of time。
The face is not torn, so that it does not cause a secondary sheeting of the surface of the surface, which inhibits growth. Under cultivation specifications, caves tend to be 30 to 50 cm wide and 30 to 40 cm deep. High-quality, decomposed chicken dung 3. 5 to 4. 0 kg, phosphorous fat 0. 5 to 1. 0 kg, compound fat 0. 2 to 0. 3 kg and 0. 5 per cent avm granular agent 10 to 15 g (prevent and kill nematodes) are applied to each of the planting dens. They are mixed with soil and then filled to half of the planting dens, with more than 10 cm of ground, flattening or slightly above the surface, avoiding direct exposure of the roots to organic burning。
Irrigation system installation
Water-efficient irrigation systems are installed in wells for irrigation of groundwater, in accordance with the terrain, selected for micro-jet irrigation, and a spray belt is laid on each plantation。
Zhang
Period of cultivation. The platinum can be grown four seasons a year, in february-april, with the choice of 10-15 leaf saplings; and september-november, with the option of 8-12 leaf saplings。
Plantation specifications. The use of wide-spread two-way cultivation, taking into account the ventilation and shade of the pelican garden, with a distance of 2. 2 to 2. 4 m, with a wide range of 2. 8 to 3. 0 m, a narrow line of 2. 3 to 2. 5 m, a planting density of 110 to 120 units, and an appropriate adjustment of the range to take into account the time of harvest, the environmental conditions of the garden and the level of plant management。
The method of breeding. A group of “gold powder 1” seedlings produced by guangxi plant production company ltd. Were planted in a large sandbed with three to four leaves and two to four roots, with three to five new leaves planted and then transferred to a seedling bag。
Planting methods. When planting, remove the nursery bag and do not disintegrate the matrix. In the absence of swirling, the bag shall not be stripped) and shall be placed in the established dens, covered with gravel and compacted with the outer layer. Upon completion of planting, 1,000 times more potassium permanganate is used for root run-through and again the next day. During spring planting, seedlings and surroundings may be covered with straw, leaves, etc., or the black membranes may be wetted and protected against grass; during autumn planting, the membranes and white membranes can be covered before the onset of the cold in december, and the membranes can be removed when the temperature rises in april。
3. Park management
Chaming sing
The seedlings are installed on the next day, and the leaks are found to be replanted in a timely manner and the tilted plant is being pressed. After heavy rains, seedlings should also be detected, and dead and weak should be replenished in a timely manner。
Fertilizer water management
Water management. During the rainy season, drains are kept open and the water on the surface is removed in a timely manner. Powder 1 should avoid flooding. The soil content of the pelican garden remained around 60 per cent throughout the reproductive period. The water content of the soil for the guillotine and poaching periods was around 80 per cent; irrigation was stopped before harvest from 10-15 d。
Fertilizer principles. Selenium require more and more timely nutrients than other cash crops. Pre-nutrient growth is dominated by nitrogen and potassium fattening; when the buds are split, i. E. When the tubers are significantly thicker and the new blades become larger, they enter reproductive growth and are applied to potassium fattening to promote fruit development. The principle of hard work, small number of times, and no harm to the roots of fertilization. Co-fertilization can be used to reduce farm operations in the field and to avoid the spread of disease from the roots of injuries。
Fertilizer programme. When the first leaf grows, urea water solution of 2kg is sprayed at intervals of 0. 2 to 0. 5 per cent per plant (with the growth of the seedlings increasing) every 7 to 10 d, until the number of new leaves is around 10. Increases of 2-3 showers for seedlings that are slightly weaker or less replenished. (a) a total of 10 to 25 new blades, with a combined weight of 50 to 100 cm of potassium nitrogen per application of 2 :1 (composed fat for potassium sulphate) of 30 to 60 g, every 10 to 15 d, at a distance of 50 to 100 cm, increasing the amount of fertilizer with plant growth; when the number of new blades reaches 15, the ratio of potassium nitrogen is gradually adjusted to 1:3。
Fertilizers can be sprayed with irrigation systems or sprayed with water on the surface. When the number of new blades is about 25, the tubers are clearly swelling and gradually enter the budding period, at which time each single application of compound fertilizer (12-12-21) 250-350g, potassium sulphate 100-1500g and phosphorus 500g is applied. When the number of new blades is about 40, the acupuncture gradually enters the guillotine period, at which time each one-time application of composite fertilizer (12-12-21) is 250 ~ 300 g, potassium sulphate 100 ~ 200g. On both occasions, heavy weight was distributed between the two branches, and soil was extracted from the subsoil of the ditch. During the first half of the month of the harvest, per 15 to 20 d of a plant, 50 to 100 g of compound fertilizer (15-15-15) is applied, which can be sprayed with irrigation or sprayed with water, and 20 to 30 d of pre-harvest fertilization is stopped。
Shorten the plant
The mills are large, the mantle is 460 to 500 cm tall, prone to wind hazards and costly to manage on a daily basis. When the pyramid is 1. 0 m high, the first 25% pp333 suspended agent is used for the dwarfation of the plant with 4. 0 to 6. 0 g, depending on the growth of the plant, the first is 1. 0 to 2. 0 g/d, the second is 3. 0 to 4. 0 g/d, the second is applied at 30 d, the water 200 to 500g soil is rinsed or sprayed at a height of 20 to 30%, and the last is applied at a safe distance of more than 9 months。
Fruit management
The school bud. The guacamole is often checked, and the position below the bud is just above the leaf handle, and the bud is carefully moved to the side of the leaf handle at an early stage so that it can grow naturally. Also cut leaves close to or exposed to buds。
Leave leaves, brushes, flowers. Depending on the flowering season, the size of the tree, and the size of the functional leaves (normally one of the functional leaves is a comb, and winter beaks are usually frozen, so one of the 1. 5 functional leaves is a comb), the development of the fruit, and climatic conditions, each string of fruit has seven to nine combs and eight combs. When the fruit finger spreads in parallel to the ground, all the nectar flowers on the comb are removed. When the fruit is about 40 to 50% full, leave leaves in the principle of one leaf to accelerate the fullness of the fruit。
Break the bud. 15-20 d after a comb, break the bud at the earliest opportunity to avoid nutrient consumption, and break the bud at 2-3 nodes at the end of the comb. The breakup should take place after noon in the middle of the morning and the wound will heal quickly, before the brushing and after the break should be performed in a timely manner。
Stand up and guard the beaks. In the event of the onset of the typhoon season or when preparing for the present, a stake may be set with a pole or wooden bar。
When the stake is erected, a hole is drilled from 15 to 30 cm in the cavity, about 40 cm deep, where the cavity is put in the cavity and pressed, and the mantle is tied to it with a rope and bound in three segments. In the case of a pillar of a non-respiratory plant, the stake shall be placed on the side tilted to the ground, the stake shall form a solid triangle of the plant and the ground, and the stake shall avoid the position of the lower part of the embroidery; in the case of an embroidered pillar, the stake shall be placed on the side or the other side of the pedestal and the plume, so as to avoid shaving with the fruit, and the upper part of the peg shall be tied to the axis。
Cleaning of pelican gardens
The seeding of the mother will consume large amounts of nutrients and, when it grows to 15-30 cm, it will be cut together with a sharp hook knife at the base of the growth point, while the dead leaves close to the ground will be cut off and removed from the garden, and soon after the sprouts will be sprayed to prevent the fungus of the wounds. A herbicide can be removed manually from the range of 40 cm, herbicides can be sprayed with tactile herbicides such as paraquat 500 times more, seeding heads with protective coverings should not be sprayed on blades, and harmful weeds should be removed from gardens and ditches and shore in a timely manner, and herbicide should cease to be used after pumping。
4. Pest management
Pest and pest control should be “preventively based and integrated”, using chemical pesticides scientifically and rationally, in accordance with the pattern of disease and pest occurrence, and effectively controlling pests. Improve the environment of the platinum garden by increasing the use of organic and potassium fertilizers to increase the resistance of plants to disease, strengthening the management of cultivation and integrated application of various preventive measures. Spraying shall be stopped within one month of the time prior to harvest。
Root nematode disease. The choice is to have a non-pathic soil or a disinfected earth bag. The platinum garden enhances fertilizer management and promotes new roots. For each 667 m2, 10 per cent of the granules of phosphorus or 0. 5 per cent of the granules of avm 1. 5 to 2. 0 kg may be applied three to four times throughout the reproductive period。
Banana atrophy. Quarantine measures are strictly enforced and the import of pollen seedlings, reproductive materials, etc. From the sick areas is strictly prohibited; organic and potassium fertilizers are increased and plant resistance is improved; in the day-to-day management process, every effort is made to avoid injuries to the beryllium or roots, while care is taken to prevent the infection of the rodents, the insect infestation of the disease, with the condition of a waterable dryer; in the field, the strains are found to be destroyed in time and lime is sprayed at the site of the disease. In the case of disease strains, a separation fence should be installed。
Bacteria. In the early stages of the disease, a 2% chronicin humid powder was selected as 800 times more liquid, 88% as a soluble powder 2,000 times liquid, 23% amino copper water 400 times liquid, or 20% as an agro-chain carcinogen wet powder 3,000 times root. Between 7 and 10d doses were administered twice and three times, with an appropriate increase in the quantity of each potion of 1kg and a larger banana plant。
Coal smoke. When the blades are opened, they are sprayed every 30 d with a 70% methyl tobutine 800 times more or 75% bacterial wettable powder 800 times more + 25% thalamus ester 1,500 times more liquid eject and juvenile fruit。
Pumpkin nose bug. The harvest was followed by the clean-up of the residues and the search for the insects hidden in them. In combination with the garden, the sheaths with eggs are regularly removed from the mantle, and insects are captured. In late november and early april of the following year, larvae peaked with poison. A 20 per cent wibo granular agent is selected for use on a teng basis; 80 per cent of dichlorvos cream, 40. 8 per cent of which is poisoned to death, is also selected for use in the upper lobe grate, 150 to 200 ml each。
Butterflies. The larvae are removed from the larvae at the onset of their hair, killing the insects in them, and the dead leaves are used as as ash and composted before winter and spring heat to eliminate the hidden larvae and larvae. During the peak of the larvae in the months of june-october, larvae were given control by chemical spraying of blades with chemical agents, which were available at 90 per cent of the crystal trichlorfon 1,000 times the fluid, 50 per cent of the thiophos-octanus emulsion 1,000 times the fluid or 40 per cent of the rapid elimination of the butter cream 4,000 times。
The mites. In the period from august to october, 1. 8 per cent of the octopus cream was sprayed with 4,000-5,000 times more liquid, 73 per cent with 1,000 times more octopus or 5 per cent with 5 per cent more octopone cream, with a focus on the lower part of the leaf。
5. Cold measures
Each plaster 1kg + phosphorus fertilizer 1kg + rotting pig dung 5-10 kg + pie 0. 5 kg, covered with white membranes, to protect the temperature and enhance the cold resistance of the plant to the winter; acupuncture trees, which have been pumped, were covered with bare handles, such as their own short leaves or cowpaper, before the onset of the cold, and more than 30% of the aluminum bags were coldproof. Spraying 70 per cent of the methyl tobuzinium 800-fold fluid + 70 per cent of the amphibian aphid 800-fold fluid against pests and pests, drying up medical fluids and making bags, using pearl cotton (in-house) + blue polyethylene film (outside bag) double-storey bags to prevent mechanical bruises, using upper and lower penetrators to avoid the disease caused by wetness in the bag. After mid-february, the temperature gradually recovered and the bags were removed in a timely manner, with 25% ethylene bacillus + 45% high-efficiency chlorocypermethrin 800 times as much as the americium disease。
6. Collection and reprocessing
When fully saturated at 90%, the fruit is harvested with a full finger, with a ten cm length on the head of the axis, which is lightened and placed on the cushion, and during the harvest, the ear cannot collide or pile together。
