I. Good seed choices and processing of potatoes
(i) selection of high-quality detoxification products: application to promote high-yield disease-resistant varieties such as viato 3 and 2。
(ii) treatment of chips
Each acre requires a potato of 150 to 200 kg, before sunbathing for 2 to 3 days, with the removal of sick and rotten potatoes, followed by cutting of blocks, making full use of the top advantage, a spiral tilting to the top, and eventually dividing by a chromium, with 1 to 2 buds per piece, with a mass of 25 to 30 g, 50 per cent wet powder with a wide spectrum microbicide, 60 to 800 times wet powder, 10 to 15 minutes after drying and seeding, which can effectively mitigate the occurrence of seed-bearing diseases caused by the seedling of the potato belt。
Technologies for different cultivation patterns of potatoes
(i) net potato production pattern
A four-foot rise of two-way cultivation at a distance of 1 to 1. 2 feet and a density of 0. 6 feet and 50,000 dens/acres。
(ii) potato condom corn
On a 5. 5-foot strip, potatoes are grown wide and narrow, 1. 2 feet narrow, and two rows of potatoes are grown up, with a distance of 0. 6 feet and an acre density of 3600; on a wide range of 4. 3 feet to 4 feet, two rows of corn are planted within a wide range, with a single directed migration plant at a distance of 1. 5 feet and a distance of 0. 6 feet and an acre density of 3350。
(iii) membrane cover cultivation model
During the appropriate period of cultivation, the ploughed soil will be opened on the basis of the specification of the pure potatoes, with the seeding of plasters in a narrow line of 1 to 1. 2 feet, with an acre density of 5,000 densities, a membranes, and a heavy membrane in the mouth of the membrane once the potato is grown。
(iv) straw cover without planting potatoes
One, the whole area
Paddy fields shall be free of cultivation and shall be 0. 6 feet wide, 0. 6 feet deep, 4. 8 feet wide and open, while the ditches shall be fenced so that the ditches can flow and the rain shall not accumulate
2. Seeding
Fresh, smooth, disease-free, small and whole potatoes weighing 20 to 30 grams each, with a distance of 1. 2 feet on the side, a distance of 0. 6 feet directly set on the side, with an eye tilt close to the ground, with a density of more than 4,000 tons per acre, seeding with a bait, and the eradication of the rodents in order to ensure the seedlings。
3. Covering straw
The seeding is covered evenly by straw on the surface of the paddy, which is light, is generally 10 cm thick, is too thick (over 15 cm) for seed production and affects yields, and is followed by guttering, and evenly crushing the paddy from the dirt that has been dug up in the ditch in order to prevent the straw from being blown away by the wind, creating a seed of potatoes。
Water management
(b) no need to pursue fattening and weeding during the production process, but it is important to ensure sufficient moisture, especially during the extended period of the tubing, evaporation on the top of the plant, rapid growth of the tubers and increased demand for water, and to maintain soil moisture in order to promote the expansion of the tubers and the decay of the rice straw, and in the event of drought, to allow for the gradual infiltration of the water into the puddles, without the use of large-water flooding, and in times of heavy rainy season or low-lying areas, to pay attention to draining water to prevent the accumulation of water in the fields and the generation of rotten potatoes
Iii. Scientific fertilization
Acres are exposed to organic fertilizers of 5000kg, n, p, k formulation (15. 15. 15) 50kg。
Iv. Main distributions
68. 75 per cent of silver flu can be used to prevent and treat early and late potato disease。
V. Enough access
In order to facilitate the harvest, where the potato skin is ageing and is not easily rinsed, water should be stopped in the fields seven days before the harvest. If the potato is removed from the ground after the harvest and stored in a place where the air is not bright, it can be stored for a month and a half。
