摘　　要：本定位评价进一步阐明了本区稻田作物布局至今仍以一季中稻为主的生态经济依据。肯定了稻田一熟改两熟能显著提高生产力，提出近期稻田改制仍应以两熟为主，改进技术，主攻单产，提高效益。同时表明本区的温光资源条件，基本能满足一年三熟正常生育的要求，但提高三熟产量的技术有待进一步研究。The experiment has further explained the ecological and economic evidence of the cropping system,a crop one year,which is the main cropping system at present.and also shows the productability can be significantly promoted through changing a crop one year into two crops one year.From now on,we should pay attention to change a crop one year into two crops one year,improve cultivation technique, promote unit yield and increase economic effect.The experiment results have showed the conditions of developing two rices one year are ready,but the technique of promoting yield and economic effcet of three crops one year still needs to be studied.
