一、正确选择作业速度。在正常情况下,若地块平坦、谷物成熟一致并处在黄熟期,田间杂草又较少,可以适当提高收割机的前进速度。谷物在乳熟后期或黄熟初期湿度较大,在收割时前进速度要低些。谷物在黄熟期或黄熟后期,湿度较小并且成熟均匀时,前进速度可适当高一些。雨后或早晚露水大时,谷物秸秆湿度大,在收割时前进速度要低一些。 First, the correct choice of operating speed. Under normal circumstances, if the land is flat, the grain is ripe and in ripening stage, the weeds are less in the field, and the advance speed of the harvester can be appropriately increased. Grain in the late milky or ripe early yellow humidity, lower forward speed at harvesting. In the yellow ripening or yellow ripening cereal, the humidity is small and mature evenly, the forward speed may be appropriate higher. After the rain or morning and evening when the dew is large, the moisture of the grain straw is large and the advance speed at harvest is lower.
