摘要
分析了寒地水稻生产中,单位面积穴数不足、均度不够、产量低的主要原因是普通人工插秧行距偏大、穴距过大。论证了缩垄增行是解决这一问题的主要技术措施,其机械行距为24cm,人工插秧实行(19+35cm)的宽窄行。指出在一定范围内,保证群体密度,田间分布均匀是保证质量、提高产量的关键。
The chief reason that cause hole number isn't sufficient ,even extent is not enough and yield was rather low within unit area is that the distances between rows and holes are too large in manual transplanting rice seedlings.Shortening ridges and adding rows are the main countermeasures to solve this problem.Its mechanical row distance is24cm while manual transplanting adopted wide-narrow row(19+35cm).Refer to guaranteeing colony density and even distribution in a certain range are the key to in creasing quality and yield.
