大豆采用机械直接收获的缺点是损失大。主要损失表现在割茬留荚、炸荚、破碎和泥花脸等。因此,研究适应大豆生物学特性的收获工艺,减少损失这是农机工作多年来一直在研究解决的问题。我场早在1962年就进行过大豆分段收获的尝试。当年因秋雨大,割晒的晚,气温偏低,致使拾禾脱谷的损失大而告失败。 The disadvantage of direct mechanical harvesting of soybeans is the loss. The main loss in the performance of stubble to stay pods, pods, broken and mud face and so on. Therefore, the study to adapt to the biological characteristics of soybean harvesting process, reduce losses This is the work of agricultural machinery has been studied for many years to solve the problem. My field as early as 1962 on the soybean segment harvest attempt. In the past due to autumn big, cut the drying of the evening, the temperature is low, resulting in picking Wo threw losses and failed.
