The Potential Influence of Temperature on Cotton Yield Structure and Development Rate
-
摘要: 该文利用新疆农业气象观测资料，在构建棉花品种熟性指数的基础上，建立了温度对不同品种棉花产量结构及发育速度影响的模式，进一步分析了温度变化对不同品种棉花单株铃数、单铃重、霜前花比例及发育速度的可能影响。该文对棉花生产气象监测、预测及评价工作有重要参考价值。Abstract: On the basis of variety maturity index of cotton, a model of the influence of temperature on yield structure and development rate for different cotton varieties is set up. By using agro meteorological observational data from Xingjiang, agrometeorological statigns during 1980~1993. The potential influences of temperature change on ball number of single plant, single ball weight, the perecentage of flower before frosting and development rate of different cotton varieties are analyzed. This work is significant in the agrometeorological monitoring, prediction and assessment of cotton production
