摘要
试验运用三元二次正交旋转回归方程对多效唑(MET)的喷施浓度、喷施时期和栽植密度对莴笋产量的影响进行了研究。结果表明,适时适量喷施是莴笋增产的有效措施,莲座期—肉质茎形成期是喷施的最佳时期,100mg/L是MET的有效喷时浓度。
In this experiment,we used tribasic quadratic prependicularity regression equation method to study the influence on the production of lettuce,the consistency of Multi-Effects Triazole＇s spracying,the timing of spraying,the density of planting.It turns out it is an effective measare for the production increasing of lettuce,appropriate spraying at proper time.The best timing for spraying is rosette stage 100mg/L is an effective concentration of MET
