优质谷子陇谷6号旱地丰产栽培研究

Study on high-yielding cultivation of high-quality foxtail millet Longgu 6 in arid land

1997～ 2 0 0 0年分别进行的优质谷子陇谷 6号旱地密度、播期、地膜覆盖及谷粒黑粉病防治试验结果表明 ,陇谷 6号旱地春播的适宜密度是 37.5万株 / hm2 ,适宜播期是 4月 2 0日 ,覆膜栽培能显著提高陇谷 6号产量 ,增产率达 5 0 %以上 ,用种子量 0 .3%的速保利和 0 .15 %的拌种双拌种能有效防治陇谷 6号粒黑粉病。

Planting density, sowing date, film mulching cultivation and smut control of high quality foxtail millet Longgu 6 were tested in arid land. The results showed that preferencial planting density and sowing date were 37 500 spike/hm 2 and April 20th respectively. Yield can be increased by mulching with plastic film and the increasing rate of Longgu 6 is over 50% and smut can be controlled by dressing seeds with 0.3% Subaoli and 0.15% Banzhongshuang.\;
