| 摘 要： | 对印度引进的木豆晚熟品种ICP70 35 ,在怒江六库进行了不同整地方法的造林试验。试验结果表明 :木豆的单株产量以全垦整地方法为最高达 0 0 6 4kg/株 ,打塘整地方法最低为 0 0 38kg/株。通过投入与产出的经济效益分析 ,得出木豆单位面积的经济效益以全垦整地最高为 3773 2 0元 /hm2 ,种植沟整地次之为 2 932 6 0元 /hm2 ,打塘整地最低为 1971 90元 /hm2 。因此 ,在坡度较平缓、土层深厚的地块 ,宜采用全垦整地方法种植木豆 ;在坡度较大的地带 ,为最大程度地减少水土流失 ,宜采用打塘整地方法种植木豆。

| Abstract: | Silvicultural experiment of different land preparation types was carried out on pigeonpea (ICP 7035) at Luku of Nujiang prefecture. The experimental results showed that the individual yield of pigeonpea treated with overall soil preparation of 0 064 kg was the highest, whereas that of the hole site preparation of 0 038 kg was the lowest. The economic benefits of different land preparation types were assessed through analysis of input and output. The results implied that the economic benefit of overall land preparation was the highest of 3 773 20 yuan/hm 2 , next came the planting channel of 2 932 60 yuan/hm 2 , and that of hole site preparation was the lowest of 1 971 90 yuan/hm 2 . It was therefore recommended to adopt overall soil preparation at flat land with deep soil layer, and to adopt hole site preparation at steep sites for avoiding or reducing soil and water loss. |
