Measures to prevent late rice seedlings

Late rice transplanting coincides with high temperature and dry season, and it is very easy to plant seedlings after transplanting. Preventive measures are: Improve the quality of ploughshares. After the early rice harvest, depending on the soil quality, irrigation conditions, etc., a plough can be applied, so that the mud on the mud can be loosened and the mud can be fused to facilitate the rooting. Straw returned to the field to prevent freezing seedlings. Generally, fresh grass is turned over on the day before transplanting late rice, and dew is sprayed 7 days to 15 days after transplanting to prevent poisoning. Straw returned to the field leveling, otherwise high-late late rice is easy to stiff or sunburned seedlings. Rational fertilization. Use manure and compost as base fertilizer, and volatile fertilizers advocate as base fertilizer. Ammonium bicarbonate does not exceed 25 kilograms per mu. It is best to apply it one day before transplanting, that is, before the last time the seedlings are applied, in order to prevent volatile gases from injuring the seedlings. If morning fertilization is planted in the afternoon, it must be filled with about 3.3 centimeters of deep water. Fully cooked organic fertilizer can be used for surface fertilizer. Reduce damage. To minimize the mechanical damage in the process of dragging, tying, transporting, and transplanting, and the leaf withering damage caused by water loss in the seedlings, and to pull, transport, and insert. Pay attention to prevent floating, elbow, and overnight. Shallow water transplanting deep-seated seedlings. When transplanting rice, there must be no mud in the field and water must be provided. Otherwise, the sun will kill the seedlings. After transplanting, the deep-water irrigation before returning green will reduce the mud temperature and water temperature, weaken the transpiration of seedlings, and promote early-onset and rapid-onset. After returning green, the irrigated fields in the well-irrigated area will be changed frequently, and the way of night irrigation will be used to increase the night's cooling rate, which will facilitate the growth of seedlings. At the same time, pay attention to the high temperature when not inserted, generally inserted after 4 pm. Rainy days grab time all day transplanting.
