农谚云:“早禾水上飘,晚禾插齐腰。”据醴陵农民经验,晚禾下午插的最好。这次在农场实习时访问了一些农工和下农业社实习时又访问了一些农民,他们说:晚禾一般择早晨与下午插,中午不插。据此,我在试验站实习时作了一个连晚不同插植时间与深度的比较试验,目的为“单改双”求得一合理的插植时间与深度,以帮助提高产量。 Agricultural proverb goes: “early Wo water floating, late Wo inserted waist.” According to the experience of Liling peasants, late at night Wo inserted the best. During the internship on the farm, they interviewed some peasants while interviewing some peasant workers and agricultural cooperatives. They said: Late Wo usually choose morning and afternoon intermission, noon is not inserted. Based on this, I made a comparative trial of different planting time and depth even after the internship at the pilot station, aiming at obtaining a reasonable planting time and depth in order to help increase the yield.
