我国小麦品种主要性状供给和需求演变

Supply-demand Evolution about Main Traits of Wheat Varieties in China

采用1982～2006年我国年种植面积在6666.7hm2以上的小麦品种数据,从性状供给和需求2个方面对小麦品种演变情况进行分析。结果表明,虽然我国生产上种植的小麦品种各性状得到明显改善,但农民对品种的产量性状需求仍是最主要的需求;农民对品种的粗蛋白含量的性状需求与供给无显著差异,对各种抗病性的性状需求近年有低于性状供给的趋势;各时期农民对全生育期的性状需求小于性状供给,而对株高的性状需求则较大。

Using the data which planting area was over 6 666.7 hm2 of wheat varieties in China during 1982 - 2006, the study make supplydemand analysis on the evolution of wheat varieties. The result showed that although China has got noticeable improvements in various traits of wheat, peasants are still most coneerried about the potential yield of wheat. As for the protein content, there is no significant difference between supply and demand. It is shown that the demand for disease resistance has been reducing in recent years. The supply for duration of wheat is more than its demand, while the lack of supply for plant height exists in the whole period.
