通过对攀西地区干旱河谷花椒品种、整地规格、造林密度、施肥量 4因素正交试验 ,结果表明 :在海拔180 0～ 2 40 0m河谷地带栽培大红袍 5年生单株结实量比正路椒、青椒分别高 2 0 4%和 32 6 % ;整地规格、株行距对结实量影响达 1%显著水平 ;施肥量对结实量影响不显著。文章阐明了攀西地区干旱河谷建立花椒丰产园的栽培技术方案 ;为该区域推广和经营花椒经济林提供优化模式。
The results showed that the five-year-old per plant of Dahongpao cultivar in the 180 0-2 240 m river valley of Panzhihua was better than that of Zhengliaojiao, Green peppers were respectively 20.4% and 32.6% higher than that of the control. Soil preparation specifications and spacing between rows and rows had a significant effect on the grain yield by 1%. The effect of fertilization on grain yield was not significant. The article clarifies the plan of cultivation technology for establishing the pepper bumper crop in arid valley in Panxi area and provides the optimized mode for the promotion and operation of the pepper biodiesel plantation in this area.
