1制种田栽培方式及管理要点1.1合理密植,兼顾制种产量和质量要求所有制种田块集中连片种植。父本、母本种植行比1∶9,母本种植密度1.65万～1.95万株/hm2,大小行种植,此密度便于人工去雄授粉操作及田间制种质量检查,正常情况下毛籽产量也可以达到1500kg/hm2以上,母本密度过大,既不便于田间操作,易造成漏花,也不利于监督管理。父本密度可加大到3.30万～3.60万株/hm2。
1 system of farming methods and management points 1.1 reasonable close planting, taking into account seed production and quality requirements of the ownership of farming plots concentrated contiguous planting. The ratio of male and female parent plants is 1: 9, and the density of female parent plants is 16500-19500 plants / hm2. The density is convenient for artificial male pollination and field seed quality inspection. Under normal circumstances, Can also reach more than 1500kg / hm2, female parent density is too large, neither easy to field operation, easy to cause leakage, is not conducive to supervision and management. Paternal density can be increased to 3.30 million ~ 3600 / hm2.
