In order to achieve the goal of high quality and high yield, what should we start from? Potato is a very popular vegetable and can be eaten as a food crop. Now China is one of the countries with more potato cultivation. Potato is an annual solanaceae crop, and its underground tuber has very high nutritional value and can be used to make starch. Has good economic value. In order to grow high-quality and high-yield potatoes, what should we start with?

1 Select potato varieties from Huanghuai and South China, which are generally divided into spring potatoes and autumn potatoes. In the case of potato selection, priority should be given to potato seeds with high quality, high yield and virus-free. If you choose to plant them, you can choose potato varieties with strong maturity, concentrated potato production, suitable for intercropping, maturity and short branches, such as Zaoxiaobai and Ray Wu.

The selected potato seeds should have no wound on the surface, smooth seed coat, many buds and moderate size, which is suitable for a certain potato variety. Before planting potatoes in spring, please check whether this potato has pests, whether it is frozen, moldy, pests and scars left by pests after winter.

The diced potato seeds are relatively large and can be planted in blocks, but the blocks should not be too small. Cut them vertically as much as possible and plant them with potato pieces with buds at the top. Smaller potatoes do not need to be cut, just use them all.

3 Seed treatment before sowing If the planting area is relatively small and fresh plant ash can be used, please immediately put the newly cut potato pieces into plant ash and soak them in plant ash. Because plant ash's solution is strongly alkaline, it has certain sterilization and disinfection effect, and there is caustic potash in plant ash, which can promote the vigorous growth of potatoes. You can also use 1 kg ethyl phosphate, 1 kg thiophanate-methyl and 25 kg light calcium powder. After mixing well, you can mix 1000 kg of potato seeds.

4 Fertilization If you want to grow high-yield and high-quality potatoes, is the organic matter content in the soil rich and colorful, which is very harmful to potatoes? Potatoes like rich and colorful organic matter, loose and breathable soil layer. Therefore, before planting, about 5 square meters of soil and enough compost should be applied per acre. If high-quality livestock manure is fully composted, 300050kg can be used before and after each acre.

Therefore, in the whole process of potato growth, urea solution and other basic fertilizers should be the leading factors, but not too much at one time. At the initial stage, urea solution can be applied along the river, with an amount of 3-4 kg per mu. After the potatoes sprout, integrated cultivation can be carried out, and urea solution can be applied within 25-30 kg per mu.

5 Field management After potato planting, drought should be maintained moderately at seedling stage to promote rooting. After the potato sprouts, it can be fertilized and watered, and foliar fertilizer can be mixed and sprayed. Generally, potassium dihydrogen phosphate+Tianda 2 1 16 is used as foliar fertilizer. The underground tuber of potato is in the fruit swelling stage, which can loosen the soil at the root of potato and prevent the potato from being damaged and reducing the quality.

6 pest control The main pests and diseases of potato are caused by underground pests. Wash the pests with 0.3% matrine aqueous solution of 500~700 ml per mu. During potato growth, 600 times of antiviral alum solution can be sprayed regularly, or 600 times of thiamethoxam copper solution can be used for prevention.
