The Main Technology Mode of Simplification,Modernization and Greenization of Facility Tomato Production
In response to the obstacles of continuous cropping in facility tomato production,the problem of environmental pollution caused by the excessive application of pesticides and chemical fertilizers and high labor costs and difficulties,facility tomato bumblebee pollination and green prevention and control of pest and disease technologies as well as using straw as fertilizer in the original field were adopted for demonstration and extension in four crop season which were over summer,late autumn,over winter and early spring.Production practice proved that these two technologies were typical simplified,modern and green production technologies that could be widely promoted,which could significantly improve the quality of facility tomato,reduce production costs,increase yield and economic benefits.The yield of facility tomato in the demonstration area could reach more than 8 500 kg per 667 m2 and the benefits could reach over 10 000 yuan per 667 m2.At the same time,it could effectively improve the ecological environment of facility agriculture,promote the development of ecological facility agriculture,and generate an effect of 1+1≥2.
