应用微机统计分析了1987—1988年直播水稻群体系统试验资料,从中明确了每亩穗数、干物重、叶面积系数、株高和上展叶长与产量构成因子中的穗数、每穗实粒数的关系,并看到六叶期与九叶期是预测穗数、实粒数的适宜时期。从而指出直播稻亩产500公斤的各生育期的诊断指标及其调控技术,以供直播稻生产应用和参考。
Using computer statistics to analyze the experimental data of direct seeding rice population from 1987 to 1988, the number of panicles per panicle, dry matter weight, leaf area coefficient, plant height, leaf length and yield components of panicle were determined. The relationship between the number of grains, and see the six-leaf stage and nine leaf stage is to predict the number of spikes, grain number of suitable period. It is pointed out that the directing rice yield of 500 kg of each growth period of the diagnostic indicators and its regulation techniques for direct seeding rice production applications and reference.
