不同耕作方式对北疆夏大豆荚粒空间分布及产量的影响
Effects of tillage patterns on spatial distribution of seeds and yield of summer soybean in North Xinjiang
摘要
Abstract
In order to explore the effects of different tillage patterns on agronomic traits,seeds per plant,space ver-tical distribution of seeds,seeds per pod,and yield of summer soybean under drip irrigation in North Xinjiang,four tillage treatments including tillage of plus (TP),tillage (T),rotary-till (RT)and no-till (NT)were adopted in large plot areas of the field.The results demonstrated that the agronomic traits of TP,T and RT were better than those of NT, among which TP was the best and T was second.Space vertical distribution of pod number and seed number per plant varied due to tillage methods.The space vertical distribution of TP,T and RT were mainly distributed in the middle and upper portions of the main stem,but NT was mainly distributed in the middle and lower parts of the main stem.The number of different seed pods was positively correlated to yield per plant.Two-seed and three -seed pods were the main compositions of the yield per plant under different tillage methods,with correlation coefficients of 0.99 and 0.98,re-spectively.TP resulted in the most number of various types of pods,and made the number of pod number and seed num-ber of per plant the most,reaching a significant difference level from other treatments (P <0.01).As a result,the yield became increased 7.43%,10.85% and 16.05% more than that of T,RT and NT respectively.关键词
