Effects Of Sugarcane Intercropping With Vegetable Soybean On The Yield And Quality Of Them And The Physical And Chemical Characteristics Of Soil

In order to investigate the effect of sugarcane-soybean interplanting on the yield and quality of them and the physical and chemical characteristics of Soil,interplant vegetable soybean in the new sugarcane variety Guitang29, research the following aspects:(1) the effect of sugarcane-soybean interplanting on their growth and quality;(2) the effect of sugarcane-soybean interplanting on the soil properties and microbial;(3)the effect of sugarcane-soybean interplanting’s density on photosynthetic characteristics of soybean;(4) the effect of sugarcane-soybean interplanting on their yield traits.the The results are as follows:1The sugarcane-soybean interplanting increase the plant height, leaf area index, dry matter accumulation of vegetable soybean and the sugarcane Brix,while reduce the fresh pod grain nutrients.The interplanting increase the plant height and stem diameter of Guitang29,while reduce the plant height and stem diameter of Roc22.2The interplanting of sugarcane and vegetable soybean improve the nutrient content of soil in sugarcane field significantly.Compared higher interplanting with Rocs interplanting,the most nutrient content of soil Rocs is higher than higher.The soil nutrient content of double row planting vegetable soybean in is higher than that of single planting in most.Intercropping of sugarcane and vegetable soybean can significantly increase soil microbial quantity.The intercropping of Guitang29and vegetable soybean is more conducive to the growth of soil microorganisms.3The planting density significantly affect its photosynthesis. The photosynthesis of vegetable soybean double-row planting is lower than that of single planting.The photosynthesis of vegetable soybean intercropping with Guitang29is lower than that of intercropping with Roc22.4The sugarcane-soybean interplanting increase the pod number per plant and yield of vegetable soybean,while reduce single pod weight and weight of100seeds of vegetable soybean pod’s commodity character. The pods,grain weight and yield of vegetable soybean double-row planted are significantly higher than that of single planted.Intercropping reduce the yield of sugarcane Roc22;Guitang29intercropping with double-row vegetable soybean significantly improve the yield.
