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:

Improving the quality of ploughshares After harvesting of early rice, the soil and irrigation conditions of the field can be plowed and ploughed, so that the mud in the field can be smashed and the mud can be fused to facilitate the rooting.

The straw-stabilized seedlings are generally used to suppress fresh grass one day before transplanting late rice, and they are drained from 7 days to 15 days after transplanting to prevent freezing seedlings. Straw returned to the field leveling, otherwise high-late late rice is easy to stiff or sunburned seedlings.

Rational fertilization uses manure, compost as base fertilizer, and volatile fertilizers as the base. 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 as foliar fertilizer.

To reduce damage, minimize the mechanical damage during dragging, tying, transporting, and transplanting, and the leaf withering damage caused by water loss in the seedlings, and be able to pull, transport, and insert. Pay attention to prevent floating, elbow, and overnight.

Shallow water transplanting deep-sea seedling transplanting seedlings, no mud, there must be water, or the sun will die in the sun. After transplanting, the deep-water irrigation before returning green will help reduce mud temperature, water temperature, weaken the transpiration of seedlings, and promote their early growth and development. 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 in the morning or after 4 pm transplanting. Rainy days grab time all day transplanting.
