Effects of Cultivation Methods on Population Structure and Yield of Rice
In order to explore the effects of cultivation methods on the population structure and yield of rice,four cultivation meth-ods were set up:mechanical transplanting,mechanical direct seeding,mechanical throwing and artificial throwing,and the change characteristics of leaf area index,dry matter accumulation and yield of rice were studied.The results showed that there were signifi-cant differences in rice agronomic traits,leaf area index,dry matter accumulation and yield among different treatments,among which the mechanical seedling throwing treatment had the best growth index and the highest yield,.
