| 摘 要： | 本文是根据1984—1985年大田资料建立的一个棉花生长发育模型。模型利用光能辐射,叶面积指数,植株干重等来计算净光合产物,并在各器官之间进行分配。利用生理学时间来预测主茎节数,根据顶芽、腋芽分化的同步序列,来确定果枝数、果节数。单铃重随其生理时间而呈逻辑斯谛克曲线分布: BW=8.2842/(1+e5.2701-0.0073×PT) 并定出蕾铃潜在增长率,根据潜在增长率求出每米~2土地上蕾铃干物质需求量,从营养供求状况来控制雷铃脱落。 根据模型预测,可确定棉花不同生育时期最佳栽培措施;与棉虫动态模型偶联,可研究棉虫动态经济阈值。

| Abstract: | In this paper,a cotton(Gossypiwm hirsutum L.)growth and development model is established, according to field experimental data of 1984 and 1985. Net photos-ynthetic production is calculated according to light radiation, leaf area index, dry plant weight etc. , and is distributed to the organs . Mainstem nodes are predicted by using physiological time. The numbtrs of fruiting branches and fruiting sites are determined by the synchrosequence of terminal bud and axillary buds. The following logistic curve is p... |
