| Abstract: | This paper discusses the preponderances of agroclimatic resburces and ways of their rational development and utilization in Sichuan Basin. The heat and water conditions are favourable factors, except the summer drought and autumn rainy weather conditions are unfavourable for yields and qulities of summer-harvested crops. Although the annual sunshine hours are deficient in Sichuan Basin, the total radiant energy can satisfy the need of the crops on the whole because the scattered amount accounts for 60%-70% of the total radiant energy. To spread wheat and rice ridge culture of the nontillage system for comprehensive utilization in paddy fields, expand cultivated area of double-harvested rice and wheat, semilate and late rice triple-cropping system, establish the base of oranges and tangerines production in Sichuan are important ways in bringing about a steady advance in agriculture. |
