1.适期扒皮晾晒田间站秆扒皮晾晒是降低子粒水分的重要辅助手段,扒皮越早降水效果越好。但扒皮过早会降低产量,过晚降水效果也不好。根据我省情况,中熟品种在吐丝后45—50天,中晚熟品种在50—55天时,在田间扒皮晾晒,为适期扒皮晾晒,不但不降低产量,而且能降低水分3—5个。 2.适时晚收在早霜来迟、气温没有明显下降的条件下,尽量晚收。晚收可使茎秆和穗抽中的营养物质继续向子粒中运输。严霜后5—
1. Appropriate grilled skin drying field stand stalks peeling drying is an important auxiliary means to reduce the grain moisture, the more effective the peeling skin the better. However, premature skinning will reduce the yield and the effect of late precipitation is not good. According to the situation in our province, medium-maturing varieties 45-50 days after silking, middle-late maturing varieties in 50-55 days, drying in the field, for suitable skin drying, not only does not reduce the yield, but also reduce the water 3-5 . 2. In due course late in the early frost late, the temperature did not significantly reduce the conditions, as late as possible. Late harvest can make stalk and ear pumping nutrients continue to transport grain. After severe frost 5-
