The first move: to tail buds. It has been proved by experiments that after the potato's tail buds become mature, the yield is only 1/3 of that of the apical buds or lateral buds. Therefore, the tail buds should not be discarded when cutting the seed potatoes. The second move: high ridge cultivation. High ridge cultivation on both sides of the soil, can increase the living soil layer, loose soil at the roots and stems, conducive to stem extension, but also can increase the temperature, to meet the temperature required for early rhizome development. The third measure: formula fertilization. Potatoes need large amounts of nutrients during the entire growth period. Fertilizers must be formulated to meet the needs of crop growth and development for nitrogen, phosphorus, potassium, and trace elements. In particular, during tuber enlargement, the yield can be greatly increased. The fourth measure: go to buds. The available part of the potato is the underground tuber. The flowering buds consume a lot of nutrients. To achieve high yields, you must see the buds to save nutrients and promote tuber growth. The fifth measure: less shovel more straight. The fleshy roots of potato tubers grow horizontally in the soil, often due to cutting off the fleshy roots by the probing scoop, resulting in artificially reduced yields. Therefore, after the end of the shovel, only the shovels are not scooped. , can effectively increase production. Sixth trick: Magnesium promotes production. Relevant experts have proved that during the growth of potatoes, especially during the expansion of potato wedges, such as magnesium fertilizer is sufficient, not only high yield, but also more starch accumulation, good quality, so when the plants are 45 cm high, with magnesium sulfate on the water-soluble After topdressing. Seventh trick: foliar spray fertilizer. In the case of applying base fertilizer, spray 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, and 1,000-fold triacontanol solution on the leaf surface every 10 days from the exhibition leaf. Times, can significantly increase production. If it can be supplemented with drying seeds, only one strong bud should be kept per plant, taking measures to fill empty and maintain seedlings, and the yield will be further improved.
