Technology integration and benefit analysis of rice+frog-mushroom comprehensive planting and breeding model
The rice+frog-mushroom comprehensive planting and breeding model is an ecological agricultural development model that efficiently utilizes the spatio-temporal resources of rice fields for annual production.In recent years,it has shown a good development trend in northwest Hubei and gradually formed a certain scale.The technical measures such as field supporting engineering construc-tion,rice planting,frog farming,and Morchella esculenta(L.)Pers.cultivation technology measures of the model were expounded,and the comprehensive benefits of the rice+frog-mushroom comprehensive planting and breeding model and the conventional planting system were analyzed.The results showed that the yield to investment ratios of the rice+frog-mushroom comprehensive planting and breeding model and the rice-rape rotation model were 1.53 and 1.46,respectively.The average net income of the former reached 201 967 yuan/hm2,which was much higher than that of the latter.Although the rice+frog-mushroom comprehensive planting and breeding model had a high cost investment,the entire process adopted green production technology,which improved the utilization rate of agricultural resources and product quality,and had good ecological and social benefits.Finally,relevant suggestions were put forward for the rational development of the rice+frog-mushroom comprehensive planting and breeding model.
