我县去年秋季少雨冬季少雪,今春无雨,土壤底墒差干旱严重。为观察玉米种子包衣后在干旱下的耐旱性和田间出苗情况,进行了此项试验。 1 材料和方法品种选用发芽力借于自交系和单交种之间的姊妹交种子予12(莫17×予20),发芽率为87%。种衣剂选用北京农业大学涿州种衣剂厂生产的玉米种衣剂19
Last year, I County less rainy winter less snow, no rain this spring, poor soil moisture at the end of a serious drought. This experiment was conducted to observe the drought tolerance under drought and field emergence in corn seed coating. MATERIALS AND METHODS Selection of germinating force The germination rate was 87% due to the cross seed between the inbred lines and single crossbreds (12 × 20). Seed coating selection of Beijing Agricultural University Zhuozhou seed coating plant production of corn seed coating 19
