合理调整减少损失1.控制割台损失在大豆收获中,割台损失一般占总损失的80%以上。控制割台损失应从减少漏割、掉枝和炸荚3方面入手。(1)减少漏割。现行垄距一般为65～70厘米,以3060型联合收割机为例,大豆挠性割台割幅为2.75米,每幅正好收割4垄,所以漏割的主要原因出在割茬高度上。割茬过低,易出现割台前集堆;割茬过高,易留“马耳茬”和切割底荚。大豆最低结荚高度一般为6～8厘米。因 Reasonable adjustments to reduce losses 1. Control of header losses In soybean harvesting, header losses generally account for more than 80% of total losses. Control of header loss should be reduced from the cut, broken branches and fried pods 3 start. (1) to reduce leakage cut. The current ridge spacing is generally 65 to 70 cm. Take the Model 3060 Combine, for example, the yield of a soy flexible header is 2.75 m, which is exactly 4 mls. Therefore, the main reason for missed cuts is the height of the cut. Cutting stubble is too low, prone to header heap before pile; stubble too high, easy to stay “stubble ” and cut bottom pods. Soybean minimum pod height is generally 6 to 8 cm. because
