The first measure: After the tail buds have been tested, it is proved that after the potato's tail buds become mature, the yield is only 1/3 of the plantlets of the terminal buds or lateral buds. Therefore, the tail buds should not be discarded when cutting the seed potatoes. The second measure: high ridge cultivation on both sides of high ridge cultivation soil, can increase the living soil layer, loose soil roots, conducive to stem extension, but also can increase the temperature, to meet the early needs of rhizome development temperature. The third measure: Formula fertilization The potato needs a lot of nutrients throughout the growth and development period, and it must be formulated to meet the demand of crop growth and development on nitrogen, phosphorus, potassium and trace elements, especially in the tuber enlargement period, which can greatly increase the yield. The fourth measure: The part of the potatoes that can be used for flower buds is underground tubers, and the buds need to consume a lot of nutrients. In order to obtain high yields, you must see the buds go to save the nutrients to promote the growth of tubers. The fifth measure: less shovel and more straight potato root tubers in the soil to grow horizontally, often due to the probe cut off the root extension of the meat, man-made reduction in production, so after the end of the shovel only shovel not shovel to earth Combining turfgrass with hand-pulling to prevent grassland can effectively increase yield. Sixth trick: Magnesium promote production research shows that in the potato growth process, especially 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 plant height 45 cm , with magnesium sulfate after the water-soluble topdressing. Seventh trick: foliar spray fertilizer in the application of base fertilizer, from the exhibition leaf, sprayed once every 10 days 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, 1000 times triacontanol Mixtures, sprayed 3-5 times, can significantly increase production. If the measures can be supplemented with drying seeds, leaving only one strong bud per plant, and picking up small seedlings to fill empty and maintain full seedlings, the yield will be further improved.
