对特矮秆小麦品种83991(株高50cm)栽培技术研究表明:亩穗数随播量的增加而增加,随播期的推迟而降低;穗粒数在10月5日～15日之间播种时,随播量的增加而减少,晚播时,以播量7.5kg/亩为最高;10月5日播种的千粒重高于其它两个播期,10月15日播种的千粒重随描量增加而略有降低,其它两个播期千粒重与播量无规律性变化,生育期变化不很明显;播期早,播量偏低,产量显高。
The study on the cultivation techniques of the special dwarf wheat variety 83991 (plant height 50cm) showed that the number of ears per acre increased with the increase of sowing number and decreased with the delay of sowing date. The number of grains per spike was sown between October 5 and 15 , Decreased with the increase of sowing rate, the highest sowing rate was 7.5kg / mu at late sowing; the 1000-grain sowing on October 5 was higher than the other two sowing dates, and the 1000-grain sowing on October 15 increased with the increase of sowing weight But slightly decreased. The other two sowing date and sowing no regular changes, the growth period is not obvious; sowing date, sowing low, the yield was significantly higher.
