Balanced fertilization and enhanced plant protection for potato production
Potatoes, commonly known as yam eggs, are characterized by high yield, strong resistance to stress, and are used as both vegetable, grain, and feed materials. The steps of potato high-yielding cultivation techniques mainly involve the following aspects:
Site preparation
Select a deep, loose, fertile sandy loam soil, requiring deep plowing in the early autumn and deep plowing 7-8 inches. This will not only eliminate weeds, reduce pests and diseases, accumulate natural precipitation, but also facilitate potato root development and enlargement of stem masses.
Seed processing
Seed potatoes should be pitted 15-20 days before sowing, and germination should be maintained under the conditions of 15-18 degrees in the cellar. After 10-15 days, most buds of seed potatoes will germinate until the size of the match head is released to outdoor leeward locations. Shaizhong, drying is generally 7 days.
Timely sowing, reasonable close planting
When the local temperature reached 8-10 degrees, the planting began. The number of late-maturing varieties per mu was about 4,000, and the number of early-maturing varieties was about 4,500. For example, the number of corresponding mu cultivars based on the production of commodity potatoes should be less, such as sales of seed potatoes. The number of acres in the main should be larger.
Scientific fertilization
Sowing should be sowing or hole sowing high quality farmyard fertilizer more than 3,000 kilograms per mu, deep application of compound fertilizer 25-50 kilograms as a base fertilizer, do not contact with seed potatoes to prevent the burning of seed potatoes, affecting emergence.
Pull out strains and degenerative strains
It must be checked twice during budding and flowering stages and it must be discovered that the degraded and miscellaneous plants must be pulled out and buried deep with the tubers to prevent virus infection and cause aging, so as to ensure the quality of seed potatoes and the quality of seed potatoes
