Potato management before and after emergence
In early May, it is an important stage for the emergence of potatoes, and it is also a crucial period for ensuring the early emergence of potatoes, the emergence of complete seedlings, the promotion of strong seedlings, and laying the foundation for high yields. Then, how should the potato be managed before and after emergence? Check seedlings, seedlings, Dingmiao After the potato is out of the line, it is necessary to timely check the seedlings and seedlings, in order to ensure that the seedlings are seeded in a timely manner to ensure the whole seedlings. After the seedlings are seeded, the seedlings are set to be seedlings, and the seedlings are set to be weak and strong. Four to five seedlings were left in the hole, and three seedlings were left in each hole after the second seedling. Cultivator The cultivating loose soil is to loosen and vent the soil of the potato layer, which is conducive to the growth of roots, elongation of tubers and enlargement of tubers. Before emergence, if the soil panel knots, loose soil should be immediately carried out to facilitate the emergence of seedlings; after the seedlings are established, the first cultivator should be carried out as soon as possible, with a depth of 8~10cm, and combined with weeding, 10~15 days after the first cultivator. For the second cultivator. When the potato is budding, the third cultivator is conducted, which is shallower than the second cultivator. At the same time, soil needs to be cultivated. The thickness of the soil should not exceed 10 cm in order to thicken the tuber layer and avoid the exposure of the tuber and reduce the quality. Timely top dressing Due to the long time from sowing to emergence of potatoes, after emergence, it is necessary to use a small amount of nitrogen fertilizer as early as possible to top up the bud seedlings to promote the rapid growth of seedlings. During budding stage, combined with cultivating soil, topdressing potato fertilizer is applied once. Fertilizer is mainly composed of potash fertilizer and nitrogen fertilizer. The amount of fertilizer applied depends on the appearance of the plant. After flowering, it is generally no longer fertilized. If the performance of defermentation and premature aging phenomenon in the later stage, the use of phosphorus and potassium or trace elements can be used for foliar spray. Chemical regulation During the budding stage, uniform spraying with 15% paclobutrazol 35g plus 60kg water per acre can prevent potato plants from growing on the one hand, dwarfing plants, thickening leaves, thickening of stems, and deepening of leaf color. Promote underground growth, accelerate tuber enlargement and increase yield. At the same time, efforts must be made to prevent and treat late blight and underground pests, so as to ensure the harvest of the high yield of potatoes.
