浙江省人多地少,历年来粮油种植面积较为稳定,且三熟制种植面积大,产量高而稳。但近年却出现了卖粮难,价格下降,种粮经济效益差的问题。随着种植业结构的调整,目前呈现出“三稳定,二减少”的趋势,即小麦、油菜、晚稻(包括单季稻)种植面积基本稳定,大麦、早稻种植面积减少。为稳定粮油总产量,提高社会和经济效益,三季品种(组合)搭配要合理,要以种植高产、优质、多抗的品种(组合)为主,以达到粮油增产,农民增收的目的。
Zhejiang Province, many people less, over the years the grain-growing area is relatively stable, and three-acre planted area, high yield and stability. However, in recent years there has been a problem of selling food, the price is declining, and the economic benefits of planting grain are poor. With the adjustment of planting structure, there is a tendency of “three stable, two reduction”, that is, the planting area of wheat, rape and late rice (including single-season rice) is basically stable, and the planting area of barley and early rice is reduced. In order to stabilize the total output of grain and oil and increase social and economic benefits, it is necessary to rationally match the three season varieties (combination) with the varieties (combinations) of high yield, high quality and multi-resistance so as to achieve the goal of increasing output of grain and oil and increasing farmers’ incomes.
