扩大春粮种植面积,提高复种指数,发展新三熟是迅速发展粮食生产的一条重要途径。选择优良的春粮品种,对于提高春粮产量,是变目前春粮低产为高产的一条有力措施。皮大麦早熟三号经过两年的试种,表现耐湿性强,抗病性好,早熟、省肥、高产,适于水田三熟制栽培的优良品种。但是,在今年长期阴雨的情况下,出现了严重的空壳现象。为了弄清其原因,使这个品种能充分发挥它的增产作用,我们对早熟三号的空壳现象进行了观察和调查,现整理如下,供各地参考,以求得正确的认识和切实的解决。
Expanding the planting area of spring grains, raising the multiple cropping index and developing new third-tris are an important way to rapidly develop food production. The selection of good varieties of spring grains, for improving spring grain yield, is the current low yield of spring crops for the production of a powerful measure. After two years of trial planting, barley early maturing three showed good moisture resistance, good disease resistance, early maturity, fertility and high yield, and was suitable for the fine varieties cultivated in the paddy field. However, during the prolonged overcast and rainy weather this year, there was a serious shell-empty phenomenon. In order to clarify its causes, so that this species can give full play to its role in increasing its yield, we observed the early phenomenon of empty shells on the 3rd and investigation, are now organized as follows for reference, in order to achieve the correct understanding and effective solution .
