1.以早促大穗.该品种对光照反映敏感。植株穗分化阶段温度高、日照长,则此阶段通过得快,不利于形成大穗。适当早播能使植株穗分化阶段的短日照、低温时间相对增长,有利穗部发育,使之形成大穗。据试验,该品种适当早播时,每穗可长16～18个小穗,而且多数穗可形成3～～4个小花,高者达5～6个,如果生育后期水肥充足,都可结实。晚播种的,每穗只长12～13个小穗,每小穗只结2～3粒种子。 1. Promote big spike early. The breed is sensitive to light. Plant ear stage of differentiation high temperature, long sunshine, then pass this stage faster, is not conducive to the formation of large ears. Proper early sowing can make the short-day and low-temperature time of plant panicle differentiation stage relatively increase, which is beneficial to the development of panicle and the formation of big panicle. According to the experiment, when the variety is suitable for early sowing, it can grow 16-18 spikelets per spike, and most spike can form 3 ~ 4 flower, the highest is 5-6, if the later period of fertility is adequate, it can be strong . Evening sowing, each spike only 12 to 13 spikelets per spike only bear 2 to 3 seeds.
