全周期胶园蔬菜间作研究初报

Yield Performance of Vegetables Intercropped in Rubber Plantation of Paired Row Planting System

胶园间作套种是国内外胶园管理常用措施,具有生态效益和经济效益双重作用。分析全周期间作模式胶园越冬期间作蔬菜的产量表现。结果表明,全周期胶园不同位置间作区的蔬菜产量差异较大,表现的总体趋势为间作区中间位置(M,W2,E2)产量显著高于两侧(W1,E1);胭脂萝卜单株产量表现优于白萝卜,与对照相比,其产量分别降低了39.4%和67.9%;胭脂萝卜间作区地上部分生物量与对照相比无显著差异;间作区豌豆产量优于荷兰豆,与对照相比,其产量分别降低了27.5%和56.7%。

Intercropping is a common practice in rubber plantations at home and abroad, which has ecological and economic benefits. The vegetables were intercropped during winter in a rubber plantation of paired row planting system and their yields were analyzed. The results showed that there were differences in vegetable yield between the locations of the vegetables intercropped in the paired-row rubber plantations. The vegetables intercropped in the middle （M, W2, E2） yielded higher than those near the rubber trees （W1, E1）. The intercrop red radish had a higher yield per plant than the intercrop white radish, and their yields were decreased by 39.4% and 67.9%, respectively, as compared with the controls. No significant difference was observed in biomass of the red radish above the ground between the control and the intercrop. The intercrop pea （Pisum sativum L） yielded higher than the intercrop snow pea （Pisum sativum var. saeeharatum）. Comparing with the controls, the yields of the intercrops pea and snow pea decreased by 27.5% and 56.7%.
