摘要
2012—2016年,平利县组织开展了桑园间作套种茶树生产效益比较试验。结果表明:桑茶间作套种第一年的生产投资较高,但低于普通密植桑园和纯茶园单独建园的投资之和;进入丰产期后,3种不同栽植密度的桑茶间作套种园的生产收益均高于普通密植桑园和纯茶园,以每667m^2栽桑1000株和750株的桑茶间作套种园生产效益较好。
From 2012-2016, a comparison experiment on economic benefits of intercropping mulberry and tea trees in mulberry orchard was carried out in Pingli County. The results show that the investment in first year of production was higher, but lower than the total of ordinary intensely planted mulberry orchard and pure tea garden; after entering the high yield period, the benefits of three intercropping orchards with different planting density were all high than that of the ordinary intensely planted mulberry orchard and pure tea garden, among which the orchard with 1000 mulberry trees and 750 tea trees per 667m^2 had the best benefits.
