Ecological effects of inter-plantation of leguminous grass in Loquat orchard

摘要: 测定枇杷园套种豆科牧草对果园植被覆盖度、牧草生物产量的动态变化、可刈性以及枇杷果实产量和品质的影响,结果表明,套种3种豆科牧草覆盖度在其生长后期或开花初期可达70%~90%,不同生育期鲜草产量以出苗至营养生长后期刈青的产量最高,可刈次数方面以只刈青2次的产量为最高。在闽南地区枇杷园套种圆叶决明可以一年种植多年生长,同时提高单位面积枇杷产量和果品的质量,降低总酸,提高可溶性固形物。Abstract: Vegetation coverage,yield and regeneration of the fresh grass,as well as yield and quality of loquat fruits by inter-planting leguminous grasses in a loquat orchard were studied.The results showed that the coverage of the grass reached 70%-90% by inter-planting three different leguminous forages during the late growth period or initial flowering stage.The highest fresh grass yield occurred during seedling emergence until the late growth period with no more than twice in cutting.Chameacrista rotundifolia was a choice perennial for the inter-plantation in southern Fujian.Compared to the control(i.e.,without inter-planted grass),the inter-plantation increased the percentage of the top-grade fruits and average single fruit weight,and decreased the total acid content of the loquat harvested.
