今年我省遇到了百年罕见的洪涝灾害,其中大部分受灾地区发生在水稻产区,再加上前期和中期的低温寡照,给水稻按期成熟带来了一定的困难。为在大灾之年尽量减少水稻的减产损失,采取水稻的中后期促早熟技术措施是十分必要的,1 排水晒田:有条件的地方将稻田的积水排干或自然落干,进行晒田,增加地温,并可以提高土壤的氧化还原电位,防止早衰,促进早熟,晒田后的水田按浅—湿—干交替程序进行灌溉管理。2 增施硅钾肥:为防止由于长期积水可能造成的
This year, our province encountered a rare flood disaster in a hundred years. Most of the affected areas occurred in the rice producing areas. Coupled with the early and mid-term low-temperature oligosols, it brought some difficulties to mature rice regularly. In order to minimize the loss of rice production in the catastrophic years, it is very necessary to adopt the early-maturing techniques of rice in the middle and later stages. 1 Drainage and tanning: if possible, the stagnant water in the paddy fields will drain or dry naturally, Field, increase ground temperature, and can improve the soil oxidation-reduction potential, prevent premature aging, promote early maturity, paddy fields after sun-shading by light-wet-dry alternate program for irrigation management. 2 additional silicon potash fertilizer: To prevent the water may be caused by long-term
