High potato cultivation techniques. Doc high potato cultivation techniques
I. Selection of plots
1. Land selection: land parcels with high topography, soil estrangement, fertility, thickness of the earth, not prone to flooding, saline is not suitable for cultivation。
Observe that the use of a block of green yolk, soybean yolk, and pushtsty long-lasting residuals is strictly prohibited. Wheat, corn, grain, groceries, followed by soybeans, sorghum, soybean, melon, beet, sunflower, eggplant, peppers, tomatoes, cabbage, cabbage, etc., share the disease with potatoes。
Deep and loose
Rotated tillage, heavy ravings, fall-drives, and fertilizing. Mcnuggets, autumn rolls, rakes, plows, suppresses. Deep pine 35 〜 40 cm。
3. Large-scale planting
Standardized cultivation techniques for potatoes of 80-90 centimetres are based on successful experiences from abroad, taking into account the actual production of potatoes in our province. The focus is on promoting the "90-centimetre mega-planting model" with a bottom width of 90 centimetres, a top width of 40 centimetres and a body height of 25 centimetres. This model, which is loosely structured and fertile, contributes to root growth, increases cassava rates, and has the advantage of light ventilation, protection against walls, drought and flooding, mitigation of early and late disease, effective enhancement of the single and quality of potatoes, which can be increased by 50 per cent, and increases in the rate of large potatoes by more than 20 per cent, a practical model of high-yield cultivation。
Seed treatment
Number of species used: 100 〜120 kg/acre planted manually; 120 〜150 kg/m planted mechanically
Acre。
2. Trailed seed: once the seed is out of the cellar 15 days before the sowing, at 13 〜 15 °c, in the dark 2 〜3 floors, gradually exposed the seeding to dispersive light, flipping every 2-3 days, allowing the seeding to be fully visible, violet buds, 〜 1 cm or so, it can be cut and ready to sow. It is necessary to avoid direct sunlight, rain and frost, while eliminating disease and rotten potatoes。
3- potato slices: cutters use 70 per cent alcohol or 5 per cent of sole water to sterilize, pick a healthy seed of cassava verticals to cut, and each plant ensures one or two robust buds. Mechanical seeding is appropriate at 40-50 grams per block. Artificial seeding, weighing 35 to 40 grams per block, is appropriate to prevent the spread of the virus and to promote whole potato seeding。
4. Combination, stifling and seed wrapping: 100 kg of potato is purified with bacillus 0. 1kg and 1 kg of smoother powder and trace elements (e. G., key, boron, copper, zinc, magnesium) mixed for a period of two days at the ventilation site, so that they can be planted as soon as the trauma heals. It would be preferable to have a potato wrapper, which would be effective in preventing the seeding of rotten seeds, killing bacteria, reducing field morbidity and increasing the rate of seedling。
Iii. Cultivation in due course
Fitness period: ten centimetres of temperature stabilized at more than 8°c is a suitable local sowing period for potatoes。
Spectrum depth: typically about 12 cm。
Seed density: thin and fat, pre-cooked main tubers and short-stairs, medium- and late-term maturity, and thin. The average ha is around 60,000。
Seeding volume: around 2,000 kg in average hectares。
Iv. Field management
Herbicide is closed
Thirty-three per cent of herbicide concentrate is 22. 5 kg to 750 kg of water per hectare, which is closed before seedlings are soaked as to effectively protect against grass and broad leaves。
Chaming sing
When the field is 4 to 5 centimetres tall, the seedlings are viewed, and the spare seedlings are transported by water in the areas where they are lacking, so that the replacement seedlings have the same growth conditions as the “sliding seedlings”。
Growing land in china. Three shovels, the first of which took place at a height of about six centimetres, have yet to be formed under the ground, so that it can be ploughed to a reasonable depth and reach 10 centimetres deep. After 10 days, the masts were not formed in large quantities, with a reasonable deep shovel, with a larger square head, to reach the level of high ground, and to return to the plough 10 cm deep. Now, for the third time in the early stages of the reais, the subterranean shrubs have been formed, and the top end of the shrubs has begun to swell, forming a truncheon, so it is necessary to make a rational shallow shovel so that it does not damage the squirts and to pick up the squirts. Three shovels to improve soil permeability and create good soil conditions for the development of the potato roots and potatoes。
