First, go to the tail buds
After the test shows that the tail bud of the potato is grown, the yield is only 1/3 of that of the top bud or the side bud. Therefore, the tail bud should not be disposed of when cutting the seed.
Second, high ridge cultivation
High ridge cultivation on both sides of the soil can increase the soil layer to loosen the soil in the rhizome, increase the ground temperature, and meet the temperature required for early root development.
Third, formula fertilization
Potatoes need a lot of nutrients throughout the growth period. In areas with poor soil and low nutrient content, they must be formulated to meet the demand for nitrogen, phosphorus, potassium and trace elements in crop growth and development, especially during tuber expansion. .
Fourth, go to Hualei
Part of the potato is the underground tubers, which do not require flowering pollination at all, and the flowering of the buds requires a lot of nutrients. In order to achieve high yields, it is necessary to see that buds are going to go to save nutrients to promote the growth of tubers.
V. Shallow cultivating and more land-breaking weeding
The meaty roots that can be agglomerated in the potato grow horizontally in the soil. It is often cut by the deep cultivating to cut the roots of the meat and artificially reduce the yield. Therefore, only the soil is weeded after the cultivating of the cultivating head, or the grass is artificially plucked to prevent grass shortage, which can effectively improve Yield.
Six, foliar spray
In the case of applying the base fertilizer, from the exhibition leaves, the spray of Fengchaobao every 10 days, supplementing N, P, K and various medium and trace elements can improve the fertilizer utilization rate and significantly increase the yield. If it can be supplemented with sun-breeding, only one strong bud will be left per plant, and the seedlings will be taken up to ensure the yield will be further improved.
Seven, prevention and control of pests and diseases
Potato pests and diseases are mainly diseases. There are mainly ring rot, late blight, black shank, viral diseases and so on. The ring rot is mainly transmitted through diseased seed potatoes, and dicing disinfection is one of the ways to eliminate infection.
(1) Comprehensive measures for the selection of disease-resistant varieties, field removal of diseased plants and selection of low-toxic pesticides.
(2) Excavation of diseased plants in the seedling stage and adult stage, and centralized treatment. The main control of late blight is the selection of resistant varieties.
(3) Select 64% anti-virus cockroach 400 times liquid, spray 50 kg per mu, once a week, even spray 3 times. The prevention and treatment of viral diseases is to promote the detoxification varieties, and the second is to prevent and cure diseases. The mites are sprayed with 40% of omethoate 1000 times liquid - 2000 times liquid. At the beginning of the viral disease, 1.5% Bacterium emulsifiable concentrate 1000 times solution, 20% virus a wettable powder 500 times liquid spray prevention, can also be used for prevention and control, and can prevent other fungal and bacterial diseases.
