水稻收获后施用0、30、75、120t/hm2牛粪作基肥,研究了基肥用量对多花黑麦草(Lolium multiflorum cv.Teragold)产量和品质的影响。结果表明,秋播多花黑麦草春季生长迅速,随生长发育的进程,在抽穗之前干物质生产量直线上升,但粗蛋白含量略有降低,体外干物质消化率明显降低;与不施牛粪作基肥的对照相比,牛粪不同施用量处理对多花黑麦草各生育阶段的干物质生产及饲草品质均无显著影响(P>0.05),农田种植多花黑麦草消化牛粪的能力大于8t/667m2。
After rice harvest, 0, 30, 75, 120 t / hm2 cow manure was used as basal fertilizer to study the effects of basal fertilizer application on the yield and quality of Lolium multiflorum cv. Teragold. The results showed that the growth of ryegrass in autumn was rapid in spring. With the process of growth and development, the dry matter production increased linearly before heading, but the content of crude protein decreased slightly and the in vitro dry matter digestibility decreased obviously. Compared with the control of basal manure, the cow manure application rate had no significant effect on the dry matter production and forage quality during the growth stages of ryegrass (P> 0.05), and the ability of planting ryegrass to digest cattle manure Greater than 8t / 667m2.
