豆科与非豆科间套作成为一种农业可持续发展模式,在保证粮食产量和维持氮素平衡中发挥了重要作用。总结分析了豆科-非豆科间套作节氮理论基础和增产原理;指出合理的豆科-非豆科间套作能有效促进豆科作物生物固氮能力,提高系统内作物养分利用率,减少农田氮素损失,有利于保护农田生态环境和维持农业可持续发展;并总结了甘肃不同生态区域生产上广泛应用的豆科-非豆科间套作高产高效种植模式及实现高产高效的重点技术措施。最后对间套作栽培在集约化农业中的应用前景及间套作生产中机械化问题提出了一些看法。以期为满足农业发展新阶段的要求和农民增收的需要,建立现代农作物高产高效技术体系和耕作制度提供一定的参考依据。
The intercropping of leguminous and non-legumes has become an agricultural sustainable development model and has played an important role in ensuring grain yield and maintaining nitrogen balance. The theoretical basis and yield increasing principle of leguminous and non-legume intercropping were summarized and analyzed. It was pointed out that reasonable leguminous and non-leguminous intercropping can effectively promote the biological nitrogen fixing ability of leguminous crops and increase the nutrient utilization rate of crop plants. Reduce the nitrogen loss of farmland, help to protect the ecological environment of farmland and maintain the sustainable development of agriculture; and summarize the high yield and high efficiency planting mode and the key point of realizing high yield and high efficiency, which are widely used in the production of different ecological regions in Gansu Province Technical measures Finally, some suggestions on the application prospect of intercropping cultivation in intensified agriculture and the mechanization problem in intercropping were put forward. With a view to meeting the requirements of the new stage of agricultural development and the need of peasants to increase income, it is necessary to provide some reference for establishing modern high-yield and high-efficiency agricultural technology system and farming system.
