1. Tail buds: After experimental observation, it was proved that after the potato's tail buds became mature, the yield was only 1/3 of that of the top buds or lateral buds. Therefore, the tail buds should not be discarded when cutting the seed potatoes.
2, 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 the extension of stolons, but also can increase the temperature, to meet the temperature required for early rhizome development.
3. Formula fertilization: Potatoes need large amounts of nutrients during the entire growth and development period. In areas with low soil nutrient content and low nutrient content, fertilization must be applied to meet the demand for nitrogen, phosphorus, potassium, and trace elements in crop growth and development, especially for tuber expansion. , which can greatly increase production.
4. To flower buds: The available part of the potato is underground tubers. It does not require flowering and pollination at all, and the buds need to consume large amounts of nutrients. In order to achieve high yields, you must see buds have to be removed in order to save nutrients and promote the growth of tubers.
5, less shovel more straight 趟 趟: potato can grow the roots of the tuber in the soil level, often due to deep cut off the root of the fleshy root, artificially caused by reduced production, so after the end of the shovel only shovel not shovel to earth Combining turfgrass with hand-glued grass to prevent grass shortage can effectively increase yield.
6. Magnesium promotes production: Practice has proved that during the growth process of potato, especially during the expansion period of potato wedges, if there is sufficient magnesium fertilizer, not only the yield is high, but also starch accumulation and quality are good, so when the plants are 45cm high, each To 500-100g magnesium sulphate dissolved after the water.
7, foliar spray fertilizer: In the case of applying base fertilizer, from the exhibition leaf, once every 10 days leaf spray once 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, 1000 times the mixture of triacontanol, Spraying 3-5 times can significantly increase production. If it can be supplemented with drying seeds, rice alcohol soaking, leaving only one strong bud per plant, taking other measures such as seedlings to fill empty space to protect the whole seedlings, the output will be further improved.
