江南春雨较多,土壤过湿,使三麦根系发育不良,造成早衰、多病、倒伏和“死熟”,影响产量。青浦县地势低洼,湿害更重。近年来关于开好麦田一套沟的办法,是防治湿害的一个有效措施。但是,如何结合本地的土质、地势、气候等条件,科学地安排沟道布局,达到省工、省时、效果好,既不误农时,又有利于高产呢?1976年我们进行了试验。
More southern spring rain, the soil is too wet, so that three maltoplasia malnutrition, resulting in premature aging, sickness, lodging and “dead,” affecting the yield. Qingpu County low lying, wet damage heavier. In recent years, a set of ditch on the way to open a good wheat, wet prevention and control is an effective measure. However, how to combine the local soil, topography, climate and other conditions, scientific arrangement of the channel layout, to save time, save time, the effect is good, neither farmers, but also conducive to high yield? In 1976 we conducted a test.
