:对 8个籽粒苋品种的生长强度、鲜草产量、籽实产量、生育期及品种性状进行了研究比较 ,结果表明红苋R10 4和红苋M7生育期中等、穗形较松散、生长强度大、产量高 ,开花期一次性测产 ,鲜草产量分别为 6 9334kg/hm2 和 6 6 134kg/hm2 ,生长强度分别为 1195kg/ (hm2 ·d)和 1181kg/ (hm2 ·d) ,比目前推广的红苋K112分别增产 2 6 4%和 2 0 4%。红苋R10 4种子产量高达 4 4 6 6kg/hm2 ,比红苋K112高 59 5% ,是其它几个品种的 1～ 3倍。比较而言 ,红苋R10 4生长强度和生产力水平明显高于其它 7个品种
The growth intensity, fresh grass yield, seed yield, growth period and variety traits of 8 amaranth varieties were compared. The results showed that the growth stages of middle-aged amaranth R10 4 and Amaranthus retroflexus M7 were loose and the growth intensity was large , The yield was high, the flowering one-time production, fresh grass yield were 6 9334kg / hm2 and 6 6 134kg / hm2, the growth intensity was 1195kg / (hm2 · d) and 1181kg / (hm2 · d) Of Amaranth K112 increased by 26.4% and 20.4% respectively. The output of the red amaranth R10 4 seeds was up to 446.6kg / hm2, 59.5% higher than that of the purple amaranth K112, which was 1-3 times of that of other varieties. In comparison, the growth intensity and productivity of R amaranthacea R10 4 were significantly higher than those of the other seven cultivars
