牧草育苗移栽比大田播种分蘖能力提高32.2～219%;多年生黑麦草、墨西哥饲用玉米和美国籽粒苋鲜草亩产分别提高7.44%、3.05%、1.26%,经 t 测定,多年生黑麦草增产达到了极显著水平(P<0.01),其余两种增产差异不显著(P>0.05)。杂交狼尾草鲜草亩产试验组比对照组下降了5.35%,但差异不显著。(P>0.05)。育苗移栽,简单易行,育苗期便于管理,避免了杂草危害,克服了天旱时牧草大田播种出苗不齐或不出苗的现象。同时也解决了草田轮作时因时间交叉与重叠的矛盾。
The yield of forage seedling transplanting increased 32.2 ~ 219% than that of field sowing. The annual output of perennial ryegrass, mexican feed corn and American amaranth fresh grass increased by 7.44%, 3.05% and 1.26%, respectively. The yield of perennial ryegrass increased Reached the extremely significant level (P <0.01), the other two yield difference was not significant (P> 0.05). Hybrid Pennisetum fresh grass mu yield of the experimental group than the control group decreased by 5.35%, but the difference was not significant. (P> 0.05). Nursery transplanting, simple and easy, nursery period easy to manage, to avoid the hazards of weeds, to overcome the drought in the field of grass sowing or lack of emergence of the phenomenon. At the same time, we also solve the contradiction between time and overlap of grass field rotation.
