5、73～07 对产量的直接作用力以每亩有效穗最大,其次是每穗总粒数,再次是结实率,最小是千粒重。通过分析可看出,其净作用犬小的顺序和直接作用大小的顺序相似。结实率和千粒重的净作用呈负值。因此说明73～07的关键技术是争每亩有效穗数,其次才是每穗总粒数,再次是提高结实率和千粒重。
5,73 ~ 07 the direct force of production to the maximum effective panicle per acre, followed by the total number of grains per panicle, again the rate of seed setting, the minimum is 1000-grain weight. Through the analysis can be seen that the net effect of small dogs in the order and direct the size of the similar order. The net effect of seed setting rate and 1000-grain weight was negative. Therefore, the key technology of 73 ~ 07 is that the number of effective panicles per acre is the second, the total number of panicles per panicle, and the second is the rate of seed setting and 1000-grain weight.
