甘蔗间种大豆最佳模式探讨
Preliminary report on the optimal model for sugarcane intercropped with soybean
摘要
Abstract
[Objective]This study aimed to screen out the best model for sugarcane intercropped with soybean in order to provide reference for the commercial production of sugarcane intercropped with soybean. [Method]Using Guichun 8 and Guitang 29 as the soybean and sugarcane intercropping cultivars, under experiments with different intercropping patterns (sugarcane spacing was between 1 m of conventional row spacing and 1.2-1.4 m of width spacing, and the soybean intercropping row number was set at 0, 1 , and 2 rows), the growth, yield traits, and yield index of both sugarcane and soybean were investigated and analyzed. [Result]After the sugarcane intercropped with soybean, the tillering rate and effective stalk number of sugarcane decreased. The effects of intercropping on the stalk diameter and plant height of sugarcane were insignificant, which, under suitable sugarcane spacing (1.4 m), would not cause the sugarcane yield to decrease. Intercropping could improve the total profit of sugarcane, of which under the condition of 1.4 m row spacing then planting 2 rows of soybeans, the total profit increased the most noticeably. Furthermore, compared with conventional row spacing, the width spacing of sugarcane planting could improve the tillering rate, stalk diameter, plant height of sugarcane and the yield of soybean. Under suitable soybean interplanting row condition (2 rows), the sugarcane yield would not decrease; as a matter of fact, the total profit of the sugarcane fields could increase. Among the conditions, planting 2 rows of soybean with 1.4 m of row spacing increased the sugarcane fields profit the most. [Conclusion]Under the conditions of this study, the optimal sugarcane intercropping soybean model was planting 2 rows of soybeans at 1.4 m of sugarcane width spacing.关键词
