文章介绍了草田轮作试验布设概况及不同轮作方式的生产力与效益。试验表明:四区粮豆轮作:豌豆—春小麦—春小麦—糜(谷)子的粮食产量较其他轮作高而稳定,应作为当前基本农田的主要轮作方式;以苜蓿为主的草粮轮作,其生物量、产能及能量产投比都较高,拟作为农田种植业的重要组成部分,因地制宜地加以发展。根据试验结果,讨论了草粮轮作的生物量、产量、适应性、对化肥的反应以及后效等方面的问题。 This paper introduces the general situation of grassland rotation test and the productivity and benefit of different rotation modes. The results showed that the grain yield of pea-spring wheat-spring wheat-minced grain (TGM) was higher and stable than that of the other rotation in the four-region grain-bean rotation system, and should be taken as the main rotation mode of current basic farmland. The alfalfa- Biomass, production capacity and energy production and investment ratio are high, it is proposed as an important part of farmland planting industry, according to local conditions to be developed. According to the test results, we discussed the biomass, yield, adaptability, response to chemical fertilizers, and the after-effects of the grazing rotation.
