今年我省的小麦生产,由于播种适时,底墒充足,苗情较好。但入冬以来雨雪较少,持续干旱,出现了一些不容忽视的问题:一是旱情严重,全省除信阳地区以外,各市地均出现了程度不同的旱象,而且旱情仍持续发展,不少地方耕层土壤含水量在12％以下;二是由于墒情差,小麦根系发育受阻,次生根明显减少变短,地上部和地下部发育不协调,降低了抗灾能力,并为后期倒伏埋下了隐患;三是部分麦田板结严重,土壤形成较厚的板结层,增加了管理难度;四是有700多万亩晚播 This year, the province’s wheat production, due to the timely sowing, enough moisture at the end enough, better seedling.

First, serious drought has led to the occurrence of drought in different cities and cities except Xinyang, and the drought still continues to develop. The soil moisture content of the topsoil is less than 12%. Second, due to the poor soil moisture, root development of wheat is blocked, the secondary root is significantly reduced and shortened, the uncoordinated development of the aboveground part and underground part reduces the ability to resist disasters, Third, part of the serious cornfield compost, the formation of thick layer of soil layer, increasing the difficulty of management; Fourth, there are more than 700 acres of late broadcast
