The paddy seeds were often broken or even damaged , and its germination rate or integral rice rate was reduced by the method of traditional half - feeding thresher , because it often impacts and sorts out paddy rice by wire - loop , rigid spike - tooth or rigid pole tooth 摘要传统的水稻脱粒系统通过刚性弓齿、钉齿和杆齿对水稻进行打击脱粒，造成水稻籽粒破碎或者籽粒内部损伤，降低了种子发芽率和大米加工的成米率。
Therefore , in the situation of advancing the structural readjustment of agricultural property , it is important to develop economy and protect the ecological environment in research on the water saving in paddy rice production and the environment protecting 因此，在当今大力推进农业产业结构调整的形式下，研究农业生产中特别是水稻生产过程中的节约用水、环境保护等问题对经济发展和生态环境保护具有重要的意义。
