Tacos are one of the foods many people like. How can they grow? Let's take a look at the method of cultivation of the taro, which you've carefully recommended。
Potato cultivation
Potatoheads are also known as taro, platinum, and the underground truncheons of the tianan star plant, whose shapes and flesh vary according to their variety, usually eating little taro. Years of tuber plants are often cultivated as one-year crops. A leaf shield, with a long and fat bearing, green or purple red, and a plant base that forms a condensed truncheon, which gradually accumulates into a meat plume known as “tatoe” or “meat”, a spherical, ovary, elliptical or block form, etc. Each section of the taro has a brain sprouts, but it has the strongest activity at the center and lower levels, with the first split, and a small tuber called “tato”, followed by “tato” from the seed, which, under suitable conditions, can form great-grandson or genus, etc。
The growth requirements of taro
Environmental requirements
Potato, multi-year plumb, often grown on a one-year crop. The foliage shield, the fat weight of the leaf, the base of the plant form a short condensed tuber, the gradual accumulation of fattening into a meat ball, or a block form, etc. However, the breathing activity at the centre and lower is the most powerful, with the first split, wet, drought-resistant, shade-resistant and aquatic properties that can be cultivated in aqueous fields or drylands. The roots have weak absorptive capacity and the whole life requires sufficient moisture; the soil is highly adaptable and suitable for the strong, rich, water-protected clay; the high temperature and humidity of the taro, which starts at 15 °c and produces a long-term demand for 20 °c temperature, and the tubers are well developed at 27 °c-30 °c。
In the early stages, with shallow, drought-resistant roots, the new plant grew into a growing plant, and with the growth of the plant, new spherical staves, i. E., fresh potatoes, continue to divide water in suitable environments, air is clean, soil is fertile, light is abundant, biological resources are diverse, and soil is suitable at ph 5. 5-7. 0, soil with organic content of around 1. 0-1. 5%, and the land is ready after autumn。
The land is tilled in winter after autumn, at depths of over 30 centimetres, with the conditional use of a hand-carryer for farming, with a large amount of land being turned over, deep and effective. It should be noted that winter farming increases the temperature of the ground, decompresses and thickens the living layer, and that small saplings are prone to high temperatures and affect the quality of the sprouts, and that, at the onset of the sprouts, the temperature of the sprouts should be reduced to 20-21°c, so that the sprouts are strong and favourable to the soil。
Zipper. Combining the whole land with fertilization by the size of the area under cultivation. Before sprouts, seeds must be selected, and out of the stored tara, strong potatoes weighing more than 40 grams are selected, and weak potatoes must be removed. Sunburn. After extracting the taro from the storage vault, it is necessary to tan for two to three days, with a slight contraction of the tail of the taro to break the hibernation and promote the growth of the bud。
Drumbs. There are several methods of seeding: the easiest method is to mix the seedlings with suitable water in a barley barley with proper water content, with a temperature of 20-25°c in the back of the sun, and to cover the temperature protection with thin membranes or grasshoppers at an early and late stage. Another method is in-house embroidery: in an indoor platinum or furnace, the temperature is constant at 20-25°c, and the seeding of seeding is carried out on an indoor shelf, which, for the purposes of management and space savings, can be placed in a full bag and do not affect the gestation, usually 30-40 days, with a view to reducing the temperature to 20-21°c before the gestation begins. In addition, in order to achieve consistency in gerontology, it should be checked in a timely manner and selected for batch management. There is also a method of seedling small sheds。
Potato farming requirements
In guangdong province, the city of le chan, called "the land of super taco head", grows the world's largest and most valuable potential for investment, weighing more than 10 pounds each. One of them, liu jin, the village's village, has the largest potato, 15 pounds. Cultivation, marketing and the use of super-potato as a high-value cash crop have also been promoted throughout the country and are of great significance for the restructuring of rural industries。
1. Temperature requirements:
The high-temperature wetland belt of taro, which is grown over a long period of time, forms of cultivation such as taro, dry water, and so on. However, both taro and taro require high temperature and wet environmental conditions, and 13-15°c of taro-heads start to grow with a temperature of 20-25°c and 20-30°c for seedlings. The difference in temperature between day and night is more conducive to the formation of the tubing, which takes place at 28-30°c during the day and at 18-20°c during the night。
2. Water requirements:
Whether taro or taro prefers wet natural environment conditions, it requires long-term soil humidity, especially with regard to the long-term abundance of leaf blades and tubing periods, the amount of water required and the amount of water required to increase the amount of water irrigated or to pour shallow water into trenches. At the same time, attention is being paid to the spraying of tirin in the field in the early stages of currying, which makes the nutrients of underground fruit transport thick, increases the vitality of the fruit, smooths the face of the fruit, strengthens the fruit, improves its quality, and brings it to productive strength. Potato life requires a certain level of water over a long period of time, ranging from 3 to 5 cm for seedlings. The leaf is grown at a depth of 5 to 7 cm, with 6 to 7 days before the harvest to control water irrigation and irrigation in order to prevent the tubers from being overwatered and intolerant for storage。
3. The light requires:
Potatoheads are weak and less stringent for light intensity. Growing well under dispersing light, the formation and expansion of the tubing requires short-lived sunlight conditions。
4. Soil requirements:
Potatoes are suitable for growth in water, with the choice of fields, low-lying areas or ditches. Despite the fact that it can grow in drylands, it still maintains the ecology of swamp plants, and it is desirable to choose the wetland zone. Taro is a fertilizing crop, and its plume is formed in the underground layer of the earth, so it should be chosen to be organically rich, deep, or viscous, with a ph value of 5. 5-7。
The point of the taro
(i) the planting time. The planting usually takes place after the end of the local frost, and the premature planting of the seed is likely to cause rotten seed。
(ii) seeding techniques
One, the seed selection, the seeding selection, the sprouts of the sprouts are intact, weighing about 50 grams, and the cylindrical stem is suitable。
2. Sun sprouts are necessary to ensure that the seedlings are ready, so that they are tan sprouts, wet stellar sprouts, etc., 15 to 20 days before they are soaked. The tarcrete in storage may be tanned for 1-2 days at the time of seeding, and the seeding may be drained into the swarms, so that the temperature is kept at 18-20°c and sowing can occur at about 1 cm over 15-20 days。
3. The food organs that sow the taro are underground truncheons, and the roots of the taro are distributed so deep that it is useful to choose soil that is rich in soil, which is strong in water. One of the important measures for cultivation is a depth of 40 cm or more before transmission, which contributes to the expansion of the tubers and increased production, with a depth of 667 m2 applied to 2,500 kg of organic fertilizer and the appropriate application of potassium phosphate, such as potassium sulfate and calcium perphosphate. Potatoes can sow at 25-30 cm range and 60 cm range, sowing at depths of 3-5 cm, immediately after sowing, covering the membrane sombranes, increasing the temperature to produce whole seedlings and strong seedlings, 150-200 kg seeding at 667 m2。
(iii) field management
One, fattening. It can be followed up once in the pre-premium period, two or three times in the early and mid-term periods of the fertilisation of a tree and a tuber, and more and more before and after application, with a combination of nitrogen, phosphorus and potassium fertilizer. It is important to control the pursuit of fats in the later stages and to avoid obscenity。
2. Watering. Potato leaves are large and evaporated, so they are watery and dry and otherwise yellow and dead. In the preceding period, because of low temperatures and small growth, soil moisture is sufficient, especially during seedling periods, to prevent the effects of root and seedling. High temperatures, high growth and high water demand in the middle and late periods, and the soil is wet, but it is desirable that water be pumped early and late, especially in the high-temperature season, to avoid watering at noon, otherwise leaves the leaves vulnerable to atrophy. Water should be controlled 20 days before harvest。
In addition, it can inhibit the growth of seedlings, and is an important technical measure to reduce nutrient consumption and promote the expansion of the tub. Therefore, before the seal, two to three times the soil of grass-breeding is cultivated, with a 5 to 7 cm interval of 15 to 20 days。
Prevention and control of diseases, which are mainly characterized by taco corruption and disease, should be addressed through a combination of agricultural measures, strict application of three-to-four-year rotations, the selection of disease-free truncheons and agricultural operations to minimize mechanical damage on the ground and underground. At the onset of the disease, 50 per cent of more than 600 times the fluid of the fungus or 75 per cent of the bacterial humid powder may be sprayed with 700 times the fluid。
(iv) the harvesting and seeding of taro should be harvested before and after the fall of the frost, when the dry roots of the leaves are fully mature but have a greater impact on production. The seeding must be fully mature and harvested before harvesting, before cutting the upper part of the ground, until the wound has been dried up and picked up in the middle of the sun, and after a day of drying up for storage at temperatures of 10-15°c, which cannot be frozen. Potato should be selected with no disease, no mechanical wounds and a tuber weighing about 50 grams。
Potato farming management techniques
Selection: it is critical to choose the varieties that are suitable for your local location, and different varieties are suitable for local planting conditions, recognized by consumers and marketed。
2 potato treatment: if it is small, duck eggs are generally small, untreated, it can be grown directly, if it is large, with fist size, it can generally be cut in two or three slices, with grasswood ash or smoother powder, and if it is dried, it can be planted. It's best to use a little taro about 100 to 150 grams。
3 - land as a whole: when a field is splattered, it rises at 1. 4 m wide (80 cn wide, 60 cm ditch) and is applied to base fat in a ditch in the middle of the field, and then covers the land, generally with a high concentration (>45% compound fat) of 50-75 kg, with better farm fat;
4. Transplantation: 3,000 strains per acre, i. E., two rows on the acre, with a distance of around 30cm, can be used to plant kbavier at the bottom, usually 2-4kg per acre, to combat underground pests. The next seed, the water。
5. Irrigation fertilization: soil moist throughout the growth period; blocking periods, combined with water, with a high concentration of 50 kg of compound fertilizer in acre, with 2 to 3 applications。
6 insects: taro-pest blades can be sprayed with agents such as high-grade salt, and ground pests can be used in the front, but not in the middle and later stages. Controls such as non-inhalant and low residual agent can be used for the mid-term and later periods。
