随着玉米种植面积的逐渐扩大,农民对玉米种子质量要求越来越高。怎样才能满足广大农民的要求呢?关键在于繁育高质量的玉米种子。在自然条件下,繁育高质量的玉米种子的最大困难就是“降水难”的问题,高茬挂晒是解决这一问题的较好办法。据吉林省毛都站镇农业站试验测定高茬挂晒的白单9降水情况表明,9月5日挂晒的,定点采样称重玉米棒4公斤,到10月4日测定该点玉米棒称重是2.05公斤,前后共用30天的时间,平均每天降水1.625%。同时,测定种子的含水量是14.3%,达到了合格的标准,收到了良好的经济效益。
With the gradual expansion of corn acreage, farmers are demanding higher and higher quality corn seeds. How can we meet the demands of the vast number of peasants? The key is to breed high-quality corn seeds. Under natural conditions, the biggest difficulty in breeding high-quality corn seeds is the problem of “difficult precipitation”. The high-stalk drying is a better way to solve this problem. According to the experimental station of Maozhan Town, Jilin Province, the determination of precipitation in the high-stained Baidian 9 showed that on the 5th of September, 4 kg of the cob was weighed and fixed on the spot, and the cob was measured on October 4 Weighing is 2.05 kg, shared 30 days before and after, the average daily rainfall of 1.625%. At the same time, the determination of the water content of the seeds is 14.3%, reached the eligibility criteria, received good economic benefits.
