At present, it is a hot summer season in late summer. After the late rice seedlings are transplanted, they are likely to lose their seedlings, return to green slowly, and delay the development of trees, affecting the early-onset and high-yielding growth of late rice. To prevent the late rice seedlings from failing to plant seedlings, the following measures should be taken: 1. Appropriately start to grow fat. To get up, the fertilizer should be transplanted in batches according to late rice transplant sooner or later. Generally, 3 to 5 days before late rice transplanting, 5-7 kg of urea or 10-15 kg of ammonium sulfate should be applied per mu of paddy field. After the dew is dried in the morning or in the evening, spray water on the leaves to prevent burning. . From the fat can promote late-season rice seedlings hair new roots, for old roots, white roots, picking a good pull, cut off less, improve seedling quality, in order to facilitate late rice seedlings inserted unbeaten seedlings. Second, improve the quality of pulling. When picking, the pickaxe should not be too big and tie too tightly. The pickaxe after picking should be placed in a ditch with water or in a ditch, and it should not be placed on a waterless board to prevent sun exposure. Take care to gently put light equipment to prevent injury to the leaves and stems of the seedlings, and to plan to use it, how much to insert, how much to pull, to prevent pulling more plugs, plug overnight. Third, avoid planting seeds in the hot sun. In the hot summer sun, planting rice seedlings, the leaves of the seedlings transpire excessively, causing the leaves of the seedlings to lose water and being easy to lose. Therefore, sunny and hot weather should not be planted in the morning. It is even more inappropriate to transplant rice under the hot sun at midday. It should be arranged as soon as possible after 4 pm. In case of rain or cloudy days, labor must be organized to make an assault. At the same time, to do a shallow plug, plug straight, do not plug in sleep, after the insertion of the irrigation of deep water protection seedlings, to prevent the field of dry sun drying seedlings, resulting in plug seedlings.
