李子林下套种西瓜效益表现

The Benefit Performance of Seed Watermelon Planting under Plum Tree

近年来贵州省大力发展特色李子产业,贞丰县四月李面积达23万亩,李子种植行间距3 m ×4 m,行间有足够的地面空间、光照及较好的通风条件,发展李子林下经济,管理投入较小,收益较高,可提高李子林综合效益;西瓜为夏季之水果,果肉味甜,能降温去暑,市场空间大。李子行间种植西瓜,既可以提高土地使用率,大幅度提高种植效益,还能减少李子的管理成本。本研究在李子林下套种“绿霸王中王”西瓜,三年李子林效益增加165.72%,5年李子林效益增加108.88%。

In recent years, Guizhou province has made great efforts to establish the distinctive plum industry. The area of April plum in Zhenfeng County has reached 230,000 mu, and the plums are planted at 3 m ×4 m row spacing. There is enough ground space, lighting and better ventilation between the rows, so as to develop the economy under the plum forest with less management investment and higher income, which can enhance the comprehensive benefits of plum forest. Watermelon is a summer fruit with sweet flesh, can lower temperature and get removal of heat, the market space is large. Planting watermelon between plums can not only improve the utilization rate of land, improve the efficiency of planting, but also reduce the management cost of plums. In this study, the benefit of plum forest increased by 165.72% in three years and 108.88% in 5 years after interplanting “The King of Green Lords” watermelon under plum forest.
