我国种植业结构调整中的饲料作物问题

继续大力发展饲料粮生产是我国今后种植业结构调整的一个方向。研究结果表明，１９９３年我国小麦、水稻的播种面积仅占总播种面积的４１％，占粮食总产量的６２％．今后一段时间的调整方向不是继续降低细粮面积和产量，而是着重于选育和改良作物的饲用品种，结合发展复种，灵活机动地发展饲料饲草生产。通过粮饲产品结构性过剩机制的初步探讨，对以往交替出现的卖粮难、卖肉难现象作了合理解释，并说明我国粮食总量过剩现象是不存在的。

Feed Crop Problem in Crop System Adjustment in China

To increase crop production is a major approach of the crop system adjustment in China.It is shown that the planting area and the yield of wheat and rice decreased to 41% of the total planting area and 60% of the total grain yield respectively in 1993.Therefore,the crop system adjustment should not continue to concentrate on reducing the planting area and the yield of grain crops,such as wheat and rice;but should focus on crop breeding and variety improving in future.Meanwhile there still exists a great potential in feed crop production in cooperation with the crop system adjustment.Through the analysis of the surplus mechanism of grain and feed production,the alternately appearing phenomena of grain surplus and meat surplus are explained reasonablly and no existence of grain surplus is proved in China.
