栽培制度优化对泽泻产量的影响
Effect of Cultivation System Optimization on Alisma orientalis of Yield
摘要
Abstract
Objective:To study the effect of combined transplanting period,drainage period,harvest period on the yield of Alisma orientalis tuber in the relay cropping system of rice-Alisma orientalis tuber/wheat or rape,to provide theoretical basis for Alisma orientalis tuber standardization cultivation.Methods:Three factors quadratic regression orthogonal rotation design was used to research,the mathematical model of transplanting period,drainage period and the harvest period on the yield of Alisma orientalis tuber was built.Results:Three factors had a significant effect on the yield,and the contribution rate of each factor to the yield was in turn for transplanting period ＞ harvest period ＞ drainage period.But two factor interaction effect were not significant,and optimal selection was obtained by using the method of statistical frequency,when the target yield of Alisma orientalis tuber was greater than 450 kg/667 m2,and under the confidence interval of 95％,the optimal agronomic cultivation measure for Alisma orientalis tuber were as follows,transplanting period on September 11 ～ 16,drainage period for 41 ～46 d,harvest period on December 11 to 16.Conclusion:Agricultural cultivation measures affected the production on the yield of Alisma orientalis tuber,in order to ensure that prevailed in rice and wheat or rape can stable increase the yield at the same time with three ripe in one year,to maximize economic benefits,which suggests that Alisma orientalis tuber is late for transplanting,extend the appropriate drainage dried period,and the harvest period properly is in advance.关键词
