龙眼园绿肥品种筛选初探

Varieties Screening of Green Manure in Longan Orchard

为筛选适宜福建省龙眼园套种的绿肥品种。选取15个绿肥品种,观测其在龙眼园中的生物性状,覆盖率、攀援性、抗逆性和鲜草产量等。结果表明,爬地蓝、圆叶决明在长势、鲜草产量、抗逆性以及虫害发生情况等方面较其他绿肥品种表现优,其中爬地蓝为多年生,具根瘤,可多次割刈,更具应用价值。本研究为龙眼园套种绿肥的推广种植提供参考。

In order to screen green fertilizer varieties suitable for interplanting in longan garden of Fujian province. 15 green manure varieties were selected and planted in the longan orchard. The biological characters, coverage rate, climbing ability,stress resistance and fresh grass yield were counted. The results showed that Indigofera Endecaphylla and Cassita rotunaifolia were better than other green manures in terms of longan growth, fresh grass yield, stress resistance and occurrence of insect pests. Indigofera Endecaphylla was perennial with root nodules that can be mowed for many times, and had more application value. This study provides reference for the popularization and planting of interplanting green fertilizer in longan garden.
