First, to tail buds: After the practice proved that the potato buds into a plant, the yield is only 1/3 of the top bud or lateral bud plantlet, for this purpose in the cutting of seed potatoes should not be abandoned after tail buds.
Second, high ridge cultivation: high ridge cultivation on both sides of soil, can increase the loose soil in the root layer of living soil layer, conducive to extension of stolon, but also can increase the temperature, to meet the temperature required for early rhizome development.
Third, soil testing and formula fertilization: The potato needs a lot of nutrients throughout its growth and development. In areas with low soil nutrients and low nutrient content, soil testing and fertilizer must be applied to meet the demand for N, P, K and trace elements in crop growth and development. Especially during tuber enlargement, the yield can be greatly increased.
Fourth, forked flower cover: potato products are underground tubers, it does not need to be obtained by pollination, and flower buds need to consume a lot of nutrients, in order to obtain high yields, must play fork caps to save nutrients to promote Tuber growth.
5. Magnesium promotes production: Experts have proved that during the growth of potatoes, especially during the expansion of potato wedges, if magnesium fertilizer is sufficient, not only the yield is high, but also the accumulation of starch is good and the quality is good. Therefore, when the plants are 45 centimeters in height, 50 to 100 grams of magnesium sulfate per plant should be followed by water-solubilization.
6. Foliar spray fertilizer: In the case of applying base fertilizer, from the exhibition leaf, spray 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate and 1,000-fold triacontanol spray once every ten days. Liquid, spray for 3-5 times, can significantly increase production.
