今年我区小麦苗期生长很好,但越到生育后期就越差劲,主要原因是4—5月份遇到了连阴雨天气而造成严重减产。当地群众说:“麦收三条沟”,即用开沟降低地下水位来防止小麦湿害。外地也有这样的好经验。 淮南稻区麦田要不要起沟排涝防湿害?起沟的效果如何?今年我们结合小麦生育期间的气象条件进行了试验。 This year, the wheat growing in our district is very good, but the worse it is, the more it reaches the later stages of fertility. The main reason is that serious rains have been caused by the rainy weather in April-May. Local people said: “Wheat received three ditches”, that is, using ditches to reduce the water table to prevent wheat from damaging wheat. There is such a good experience in the field. Huainan rice fields wheat or drainage to prevent dampness? What is the effect of ditch? This year we combine the wheat during the meteorological conditions were tested.
