Key Technology Research and Economy Benefit Analysis of Early Ripening Varieties of Spring Soybean Intercropping in Sugarcane
摘要
Abstract
Sugarcane-soybean interplanting techniques, such as interplanting different soybean varieties, applying different soybean seeding time and fertilizing the interplanted soybean with different fertilization rate, were studied to evaluate their economic benefits, with the purpose to explore a scientific interplanting cultivation and to provide a basis for mass production application. The results showed that, when interplanted with soybeans, the cane height, the cane stalk diameter, and the cane stalk weight would increase but the millable canes per unit area would decrease, therefore the cane yields would also get influenced. Three soybean varieties performed well and would be suitable to interplant with sugarcane without negative influence to the growth and yields of sugarcane. The suitable seeding time of the interplanted soybeans would be in early March, 15 days after cane planting. The suitable fertilization rate for the soybeans would be 225.0 kg/hm2 when the fertilizer was N-P-K compound fertilizer with N:P:K ratio of 18:18:18.关键词
