小偃6号于1977年育成,1978年开始示范、推广。1981年3月经省农作物品种审定委员会批准为关中灌区的推广品种。现根据播期和播量试验结果,结合各地生产上的表现,对小偃6号的主要特性与栽培技术作一简要总结。一、主要特性 1.分蘖力强,成穗数多:小偃6号冬性。根据我所1978年—80年试验结果,在肥地,适时播种,基本苗在7—8万时,冬前分蘖每亩可达80—90万,春季分蘖可达90—110万,每亩成穗数在45万左右。平均每亩冬前分蘖比丰产3号多14.5万,春季分蘖多16.7万,每亩成穗数多3.1万,平均比丰产3号增产18.5％。
Xiaoyan No. 6 bred in 1977, 1978 demonstration, promotion. In 1981 March by the Provincial Crop Variety Approval Committee approved Guanzhong Irrigation District promotion varieties. Now based on the sowing date and sowing test results, combined with the performance of production around, Xiaoyan 6, the main characteristics and cultivation techniques for a brief summary. First, the main features 1. Tillering ability, the number of spikes: Xiaoyan 6 winter. According to my 1978 - 80 years of test results, in the fertile land, timely sowing, the basic seed in the 7-8 million when the winter tillering up to 80-90 million per acre, spring tillers up to 90-1.1 million acres Into the spike in the 450,000 or so. The average number of tillers per acre was 145,000 more than that of No. 3 at the beginning of winter, the number of tillers in spring was 167,000, the number of spikes per acre was 31,000, and the average yield was 18.5% higher than that of No.3 at high yield.
