Mechanized High-Yield and High-Efficient Technology Model for Double-Cropping Rice and Its Application Effects
To advance the whole process mechanization production of double-cropping rice,an integrated technological model was developed,encompassing mechanized land preparation,mechanized fertilization,mechanized lime application,mechanized seeding and seedling raising,mechanized transplanting,mechanized ditching,mechanized plant protection,mechanized straw smashing and returning,mechanized deep plowing,and mechanized green manure seeding,and a 17 hm2 demonstration application of the model were carried out in Miluo City,Hunan Province,China in 2022.The demonstration showed that this model increased annual rice yield by 2.19 t/hm2 and net income by 4 782 Yuan/hm2,significantly enhan-cing the yield and economic benefits of double-cropping rice.
