摘要
采用随机区组设计,研究青刈对饲用甜高粱杂交种天青一号产量和品质的影响。试验结果表明:相同肥密条件下,青刈甜高粱的总鲜重产量显著高于相应常规收获处理的产量,采用混合肥总量为236.30 kg.hm-2,密度为30万株.hm-2的垄上双行处理进行青刈是最佳利用方式,产量可达68.20 t.hm-2;青刈甜高粱总体效果表现为鲜重产量高,植株鲜嫩,即可青贮又可青饲。
Randomized design was used to study the influence of harvest by stages on hybrid sweet sorghum＇s yield and quality.The results showed that the fresh grass yield of harvest by stages was higher obviously than that of usual one-step-harvest under the same fertilizer and planting density.The most optimal available double rows ridge in a field disposal：fertilizer gross quantity was 236.30 kg·hm-2,planting density was 300 000 plant·hm-2,and fresh matter yield got 68.20 t·hm-2.Total effect of the harvest by stages was high-yield and fresh-tender plant,which could be not only fit for silage but also as feed.
