從農(nóng)業(yè)部門調(diào)查情況看，今年河南省小麥長勢是近年來最為均衡的一年，麥田總體呈現(xiàn)群體充足，個體健壯，根系發(fā)育好，分蘗增多，地上地下生長協(xié)調(diào)的特點。其中，洛陽、三門峽等旱地麥區(qū)因雨水充沛，小麥單產(chǎn)預(yù)計較上年增加10%以上；周口、商丘、南陽、駐馬店4市夏糧生產(chǎn)形勢明顯好于上年，由于4市小麥播種面積大，增產(chǎn)量預(yù)計占全省的70%；豫北、豫中等地總產(chǎn)也較上年略增。
據(jù)了解，由于河南省麥撥后墑情適宜，小麥出苗情況好，越冬期一、二類苗比例占89.9%，大部分麥田實現(xiàn)了壯苗越冬。返青期一、二類苗比例占93%，較去年同期增加了4.4個百分點，尤其旱地麥區(qū)一、二類苗較常年更是明顯增加。同時，河南省春季小麥病蟲害防治投入力度大，累計防治面積2.55億畝次，占發(fā)生面積的140%，為夏糧豐產(chǎn)豐收贏得了主動。
