本试验针对红壤新开地的特点,对5个抗旱、耐酸、耐瘠牧草品种进行了基肥效应的研究,结果表明:红壤新开地施用基肥能促进牧草出苗、生长、刈割、再生,并提高产量,其中有机肥效果最好。不同品种对基肥的反应有较大的差异,冬季俄勒冈黑麦草、徐苕3号,夏季杂交狼尾草、印尼大绿豆可作为红壤新开地的先锋作物。
In this study, based on the characteristics of newly opened red soils, the effects of basal fertilizer on five drought-tolerant, acid-tolerant and weedless pastures were studied. The results showed that the application of basal fertilizer on the newly opened red soil could promote the emergence, growth, cutting and regeneration of forage Improve production, of which the best organic fertilizer. The responses of different varieties to basal foraminifera were quite different. Winter Oregon ryegrass, Xuhuang 3, summer hybrid Pennisetum and Indonesian big mung bean could be regarded as pioneer crops in red soil.
