从试验研究和生产实践证明,采用多种绿肥混播,是一项提高绿肥产量的有效措施。由于豆科、禾本科和十字花科等绿肥的根系分布的范围不同,根系分泌物、根际微生物区系、对土壤养分和水分要求、生长特性以及抗逆性等诸方面不同,因而合理搭配混播能充分利用空间、土地和光能,夺得绿肥高产。 From the experimental research and production practices have proved that the use of a variety of mixed green manure is an effective measure to increase green manure production. Due to the different root distribution of green manure such as leguminous plants, grasses and cruciferous plants, root exudates, rhizosphere micro-flora, soil nutrient and water requirements, growth characteristics and stress resistance are all different Mixed broadcast can take full advantage of space, land and light energy, won the green manure high yield.
