| 摘 要： | 对果蔗田不同种植方式的光能利用率及经济效益进行比较研究,结果表明:(1)果蔗间作番茄和黄瓜,其光能利用率达1.7705%和2.8391%,较果蔗单作分别提高48.5 7%和138.24%;每公顷纯收入分别增加2476.35元和699.00元。(2)间作的生物产量与经济产量都显著高于单作;前者的土地当量值(LER)均超过2,显示了间作有提高农田生产力和增产的效果。还测定了不同种植方式对土壤部分化学特性的影响。

| Abstract: | The aim of this experiment is to find out the light energy utility and economic effects of ditferent crops intercropping in the chewing cane field. Results show that,1.Intercropping with tomato and cucumber in the cane field,the energy utility approached to 1.7705% and 2.8391%,with inereases of 48.57% and 138.24% respectively in comparison with single chewing cane as the check.The economic effects increased to 2476.35 yuan/ha and 699 yuan/ha respectively.2.Intercroping patterns were significantly profitable in both biomass and economic yields than single cane crop patterns.The land equivalent rates (LER) were bigger than 2. This indicates that intercropping promotes land productivity and increases crop yields.3.Different cultivation patterns also affected the soil chemi- cal characteristics |
