1 玉米种子的收获时期多年生产实践证明,靠自然晾晒降低种子的含水量,确定适宜的收获时期是一项关键性措施。我们曾做过试验,结果是9月15日收获的,虽然收获当时种子含水量达48.12%,经过30d的晾晒,种子含水量下降到13.29%。收获期延迟到10月2日的,虽然收获当时种子含水量只有25.89%,比9月15日收获的降低22.23%,由于10月份气温较低,直到
1 corn seed harvest years of production practice has proved that natural drying to reduce the seed water content, determine the appropriate harvest time is a key measure. We have done the test, the result is September 15 harvest, although the harvest was 48.12% moisture content of seeds, after 30d of drying, seed moisture content dropped to 13.29%. The harvest period was delayed until October 2, although the moisture content of the seeds at the time of harvest was only 25.89%, 22.23% lower than the harvest on September 15 due to the cooler temperatures in October until
