市场需求大玉米增播快由于玉米市场价格行情看好,加之它的商品经济价值高,加工食品品种丰富,例如玉米油、玉米方便面、玉米罐头等等,它还是各类饲料的主原料,另外,玉米还是我区出口创汇各种粮食中的主要品种。因此,1994年我区玉米播种面积比例较往年有较大增加...
The market demand for large maize broadcast fast As the market price of corn is optimistic about the market, coupled with its high economic value of the commodity, rich variety of processed foods, such as corn oil, corn, instant noodles, canned corn, etc. It is the main raw material for all types of feed, Corn or my region exports all kinds of food exports of the main varieties.
