安宁河流域稻田主要种植模式生态经济效益分析

Analysis on Economic Returns of Several Paddy Field Planting Patterns

针对安宁河流域稻田主要种植模式进行了多年定点的试验研究，并采用反映“三大”效益（经济效益、生态效益、社会效益）的10个指标对其效益进行了综合评价。结果表明，8种稻田种植模式的效益大小顺序为麦＋菜—玉—稻、麦＝玉—稻、豆＋菜—瓜—稻、麦＋菜—瓜—稻、麦＝瓜—稻、豆＝瓜—稻、麦—稻、豆—稻，而且稻田多熟种植的光能利用率均在3％以上，总产值超过3．3万元／hm2，净产值在2．7万元／hm2以上，纯收益2．4万元／hm2以上，是攀西地区有条件的地方选用的高产优质高效种植模式。

The author have done many years fixed noint experiment and re-search on the rice field planting model in the Anlin river basin. Ten indexes of three benefits (ecology benefit,economic benefit,society benefit) were used to evaluate it. The result showed that the eight kinds of rice field planting model,s benefit when ranking from high to low are: wheat+vegetable-corn-rice; wheat=corn-rice, bean+vegetable-melon-rice, wheat+vegetable+melon -rice, wheat=melon-rice, bean=melon-rice, wheat-rice, bean-rice. And in the rice field of many crops the annual rate of plant,s use of light energy is over three percentage. The Gross output value was 33000 ZMB yuan per hec- tar,the net output is over 2700 yuan/hm2,the net benefit is over 2400 yuan/hm2. The are beneficial planting patterns for Panzhiua and xichang areas.
