2005.2006年间,在印度喀什米尔地区的克什米尔农业科学大学的试验地对农林兼作体系进行研究,柳树与农作物的间混种植包括柳树,羽衣甘蓝(Brassica oleracea Var.acephala)和球茎甘蓝(Brassica oleracea var.caularapa)。试验地分成几个小区,每个小区(8m×2m)种植4棵两年生的柳树,间距为2m×2m。采用被推荐的间混种植的植株间距和施用的肥料浓度。结果表明:羽衣甘蓝和球茎甘蓝与柳树间混种植得出这种的种植模式的预计效益成本率分别为2.78和2.79,单独的柳树种植效益率为2.66。本研究表明,可以促进蔬菜作物与柳树间混种植模式从而代替单独的柳树种植模式。图1表7参27。
In 2005-2006, we studied the agroforestry system at the experimental site of Kashmir Agricultural Science University in Kashmir, India. The interplanting of willow with crops including willow, kale (Brassica oleracea Var. Acephala) and Brassica oleracea var. caularapa). The experiment was divided into several plots. Each plot (8m × 2m) was planted with 4 biennial willows at a spacing of 2m × 2m. The recommended interplanting spacing and applied fertilizer concentration are used. The results showed that the estimated cost-effectiveness rates for planting this kale between kale and kohlrabi were 2.78 and 2.79, respectively, and the yield of willow alone was 2.66. This study shows that it is possible to promote mixed cropping patterns between vegetable crops and willow trees to replace single willow planting patterns. Figure 1 Table 7 Reference 27.
