1站秆扒皮,收前降水在种子乳熟末期至蜡熟期之间,将玉米果穗的苞叶扒开,使果穗暴露在空气当中,可收到明显的降水效果。扒皮时间在9月上中旬,收获前10~20d进行。试验表明,收前20d扒皮可比对照多降水9.7%,收前15d扒皮可降水8.6%,收前9d扒皮则降水6.5%。站秆扒皮尤其适用于那些生育期偏长,活秆成熟和籽粒脱水较慢的组合。2适期早收,高茬晾晒乳熟末期的玉米种子已具有较好的种用品质,是适
1 station stalks skinning, pre-harvest precipitation in the milk ripening period between the wax maturity, corn ear bracts leaves open, so that the ears exposed to the air which can receive significant precipitation effect. Grilled skin time in mid-September, before harvest 10 ~ 20d. The results showed that the first 20 days of harvesting could have 9.7% more precipitation than the control, the first 15 days of harvesting could have 8.6% of precipitation, and the first 9 days of harvesting had a precipitation of 6.5%. Stalk peeled peel particularly suitable for those long growth period, live stalk and grain dehydration slow combination. 2 early harvest, high-stubble dry milk end of the corn seed has better quality of use, is suitable
