我县常年小麦播种面积40万亩,经过对今年的小麦苗情考察分析,总结出有如下特点和存在问题,并提出相应的田间管理措施。一、苗情特点1、播种偏早。适期播种面积下降。10月7日—15日(适期)播种面积24万亩,10月7日前播种面积14万亩,10月16日后播种面积2万亩。2、播量偏大,基本苗偏多。因群体偏大,麦苗生长拥挤,形成细弱苗。有些适期播种麦田播量达15—20公斤。3、出苗齐全,全县40万亩整体出苗比较齐
My county annual perennial wheat sown area 400000 mus, after this year’s wheat seedling investigation and analysis, summed up the following characteristics and existing problems, and put forward the corresponding field management measures. First, the characteristics of seedlings 1, sowing earlier. Sowing area decreased. October 7 -15 days (the appropriate period) sowing area of 240,000 mu, October 7 sowing area of 14 mu, after October 16 sowing area of 20,000 mu. 2, sowing is too large, more than the basic Miao. Due to large groups, wheat seedlings grow crowded, the formation of weak seedlings. Some sowing wheat crop sowing capacity of 15-20 kg. 3, complete emergence, the county 400000 acres of the whole emergence of more homogeneous
