Potato cultivation technology
1. Choose the cut and plow. Based on the characteristics of the cassava circulatory, cascading, acoustic micro-tacid soils, the choice of wheat stubbles and corn grains, the stubling of the former crop after the harvest, the holding of voltage and autumn tillage, the storage of water, the pre-semination fineness, the decomposition of the soil and the increase of temperature protection. It is made of 0. 2 kg of zinc parathion, which is applied into the soil to combat underground pests。
The planting of seeds is carried out on a regular basis, in order to promote mechanical planting. The “sing ming-ting rain” is the right time to sow, i. E. In mid-april, when the 10-cm earth temperature reaches 8-10°c, it is fast enough to be broadcast early, prompting earlier rooting and nurturing the seedlings. The seeding method is a gutter plant, i. E. 55 centimetres wide, 35 centimetres narrow, or 40-50 centimetre line, with a range of 30-35 cm and 4,500-5,000 acre seedlings. At the same time, the promotion of mechanized cultivation techniques has been actively pursued, with a one-time effort to sow, fertilize and produce soil, with a view to achieving efficiency gains and savings。
3. Choose high-quality potato detoxification. High-quality starch varieties, such as potato 3, 6, 7, potato 3, new terrace, provide high-quality, specialized potatoes for the starch processing industry and increase production value and income。
Seed treatment. The promotion of seeding of small, small (50g) potatoes, which are cut in blocks, which weighs 30-50 g, each with one or two buds, is immediately removed from the slice, 40 per cent of the formaldehyde or 75 per cent of the alcohol is used to wash the potato, disinfected, well-cut chips are sown with grass and graze, and then sown to the wound to heal and sow, while actively promoting the application of wrapping techniques。
5. Application of membrane-covered cultivation techniques. Covering the membrane can substantially increase yields, while serving as a vegetable for the morning market to achieve greater efficiency and efficiency. Membrane methods: first, membrane semi-film coverage using 700-750 x 0. 01 mm; second, membrane full-film coverage using 1200 x 0. 01 mm. Four thousand acre seedlings, and then the earth covers the hole。
6. Balanced fertilization. Based on the demand pattern of potatoes and soil nutrients, the acre application of high-quality farm fat for 1,500-2500 kg, urea for 10 kg, calcium perphosphate for 20-30 kg, potassium sulphate for 5-10 kg, or high potassium-type formulation for 40-60 kg, and other micronutrient fertilizer, which is applied at 2-3 cm to the diatoms and avoids direct contact with seeding to avoid harm。
7. Periodic harvest. The harvest occurs when most of the plant leaves are turned yellow from green to dead, and the tubers stop growing and are easily separated. On the ground, between the end of september and the first half of october, harvests are chosen on a clear day, with the soil dry and on time, and without touching the potato skin。
8. Storage. The post-harvest potato is stored in a cassava-eating and seed-planted cellar to ensure quality, keeping the cellar at 1-3°c and 90% humidity. (10)
