大麦矮苗壮拌种的种子通过不同播期、密度试验 ,结果表明 ,大麦用矮苗壮拌种 ,生育期普遍推迟 ,生育进程普遍减慢 ,出苗率降低 ,基本苗减少 ,不同生育期单株分蘖、群体总苗数普遍减少 ,株高降低 ;适期早播 ,基本苗 30 0万 /hm2 以上 ,增产显著 ;迟播晚苗 ,基本苗偏少田块 ,普遍减产。推广应用 ,还需进一步研究。 Barley seedlings were planted with different sowing date and density. The results showed that the barley was strongly planted and sprouted, the growth period was generally delayed, the growth process was generally slowed down, the emergence rate was reduced, the basic seedlings were reduced, and the single growth stage Plant tillering, the total population of seedlings generally reduce the plant height; early sowing early, the basic seed 3000000 / hm2 above, significant yield; late sowing late seedlings, the basic seedlings less fields, generally cut. Promote the application, need further study.
