随着农村生产责任制的落实,我省水稻栽培技术有很大提高,大部分稻区单产都在千斤以上。但也有的农户求高产心切,施肥量过大,密度过高,水分调节不适当,造成水稻群体过旺,导致病害或倒伏减产。水稻栽培管理中的晾田和烤田,是控制群体过旺的有效手段,两者间的区别和运用方法介绍如下。什么是晾田和烤田?晾田和烤田,也有的地方通称为晒田,两者都是水稻高产栽培中的水分调节形式。晾田,在水稻各生育期都可进行,每次连续1～2天。晾田时田面没有水层,但土壤水分仍较充足,基本保持在土壤水分饱和和最大持水量上下,既可调节水稻生态环境,又可起到轻度的控制作用;烤田,在水稻分蘖末期到幼穗分化期进行,以控制水稻生育为主。烤田时,田面
With the implementation of the responsibility system for rural production, rice cultivation techniques in our province have greatly improved, most of the rice yields are above the kilos. However, some peasants also seek high yielding products with too large an amount of fertilizer, too high a density and inappropriate water regulation, resulting in overpopulation of the rice population, resulting in disease or lodging and yield reduction. Rice cultivation management in the fields and baked fields, is an effective means of controlling the population over-consumption, the difference between the two and the use of methods described below. What is the field of drying and baking? Drying fields and baking fields, also known as Sha Tin in some places, both high-yield cultivation of rice in the form of water regulation. Dry fields, in the rice growth period can be carried out, each successive 1 to 2 days. When there is no water layer in the field, the soil moisture is still adequate, and the soil moisture content is basically maintained at the maximum and the maximum water holding capacity, which can not only regulate the rice ecological environment but also play a slight role in controlling the environment. The end of the panicle to panicle differentiation to control rice-based. Baked fields, the surface
