A Preliminary Study on Planting Pattens and Resource Utilization of High-Yield and High-Benefit on Rice Land in Anning River Basin

The present paper deals with the productivity,money input and output,resource utilization and cultural practices of different planting pattens on rice land in Anning River Basin,Sichuan Province.The-basin was the main parttion in Panxi area.There were the rich in light-thermal re- sources at the basin,In the middle and down stream of Anning River,the thermal resource was the first at Sichuan.Based on the experimental results in the middle stream of Anning River dur- ing 1991-1992,the yield,benefits and utilized coefficient of light-temperature resources in wheat +vegetable-watermelon-rice,fababean+vegetable-watermelon-rice,and fababean-watermelon- rice were better than other planting pattens.Among these,the benefit in wheat-rice was the least.
