不同株型小麦新品种超前繁育技术和效益分析

Study on the Leading Breeding Technology and Benefit Analysis to Different Wheat Plant Types

采用不同播种方法对两种不同株型的小麦品种的繁殖系数和经济效益进行研究分析,结果表明:小麦新品种超前稀繁的繁殖系数随行距扩大而提高; 3cm株距时,紧凑型品种的超前繁育以 40cm行距为宜,松散型小麦品种的超前繁育以 50cm行距为宜,均可获得最高经济效益。

By adopting different sowing methods, we analyse the breeding indexs and economic benefit of the two various kinds wheat plant types, It indicates that the breeding index of the leading scattered breeding of the new wheat variety increases with the row spacing expand, 40cm (row spacing) is proper for the variety whose leaves are upward and 50cm is suitable for the ones whose leaves are downward, Thus, great benefit can be gained when we take the two methods.
