广东近几年发展起来的水稻“低群体”高产栽培技术,它的主要内容是:生育前期在确保计划穗数(茎数)的前提下,尽量降低苗峰,为中期粒数发育创造条件,在协调穗数与粒数发展的同时,扩大后期同化面积,延长叶片寿命,增强同化物质来源,提高结实率和千粒重。力求以低消耗,低成本而取得高效益、
In recent years, the “low-population” high-yielding rice cultivation technology developed in Guangdong has the following main points: In the early stage of growth, under the premise of ensuring the number of spikes per plant (number of stalks), Miao Feng should be reduced as much as possible to create conditions for the mid- While coordinating the development of spike number and grain number, the area of late assimilation should be expanded to prolong the life of leaves, enhance the sources of assimilation materials, increase the seed setting rate and grain weight. Strive to low consumption, low cost and achieve high efficiency,
