1.机收水稻籽粒破碎的原因 (1)水稻品种的影响。水稻的类型很多,按稻种类型分有籼稻和粳稻。籼稻谷粒狭长,颖毛短稀;粳稻谷粒短圆,颖毛长密。在相同的状态下,联合收割机收割籼稻容易出现断米和剥壳现象。另外,还存在着品种变异的影响,如1998、1999、2000年我们用桂林-3、桂林-6等机型收割太湖糯米型水稻时,表现为难脱,几乎无破碎,但2001年收割时表现为易脱、有破碎现象,并且调整操作不当时,破碎率更高。
1. Machine-made rice grain broken reasons (1) the impact of rice varieties. There are many types of rice. There are indica rice and japonica rice according to the type of rice. Indica rice grain narrow, Ying Mao short; Japonica rice short circle, Ying Mao long dense. Under the same conditions, the combine harvester is liable to be broken rice and peeled off the indica rice. In addition, there are varieties of variation, such as 1998, 1999, 2000, when we use Guilin -3, Guilin-6 and other types of rice harvesting in Taihu Lake, the performance of hard to break, almost no broken, but the performance of the harvest in 2001 For easy to take off, broken phenomenon, and adjust the improper operation, higher crushing rate.
