种植绿肥对培肥改土、发展农牧业生产有重要作用。尤其在我区能源紧缺,秸秆及牲畜粪便等有机物质不能大量还田,而土壤肥力又逐渐下降的情况,大力发展豆科绿肥及牧草生产更显得重要。我们试图通过春播、秋播以及复种等方式,探讨在一定生态条件下绿肥的生长发育状况,鲜草产量,培肥效果及其对后作产量的影响,为我区绿肥的生产与利用提供新的技术途径。
Planting green manure to soil improvement, development of agriculture and animal husbandry production has an important role. Especially in our region, energy shortage, straw and livestock excrement and other organic matter can not be returned to a large number of soil fertility and gradually decline, to develop legume green manure and forage production more important. We try to explore the growth and development of green manure under certain ecological conditions, the fresh grass yield, the effect of fertilization and its effect on the yield after the spring sowing, autumn sowing and multiple cropping so as to provide new production and utilization of green manure in our region Technical approach.
