灌浆期是小麦籽粒形成的重要时期。在灌浆期合理灌水创造良好的土壤水分条件,确保小麦籽粒正常灌浆,防御各种灾害,是保证小麦高产稳产的关键环节。对小麦灌浆期的合理灌溉,众说不一。有的认为灌浆期地皮不能干;有的认为灌浆期的前期要湿润、后期应逐渐干爽;还有的提出灌浆水要两头搁,即在灌浆期的两头要各灌一次水,我们认为有必要认清小麦灌浆规律,找出小麦灌浆增重的影响因素,从而确定保证增重的灌水措施。
Grain filling stage is an important period of wheat grain formation. Reasonable irrigation in the filling stage to create a good soil moisture conditions to ensure the normal grain filling of wheat to prevent various disasters, is to ensure high and stable yield of wheat key link. Irrigation of wheat during the rational irrigation, different. Some believe that the filling of the land can not be dry; some think that the early filling period should be wet, the late should be gradually dry; some proposed grouting water to be two heads put, that is, in the filling of the two ends of each irrigation water, we think it necessary Identify the law of wheat grouting and find the influencing factors of wheat grain weight gain, so as to determine the irrigation measures to ensure weight gain.
