提高青饲单产,增加青饲的经济效益,有利于扩大青饲的种植面积,促进市郊饲养业的发展。试验证明:①奥勒岗黑麦草生长势和再生力强,刈割利用期长,鲜草刈割量显著高于冬牧70黑麦,可以代替冬牧70黑麦在市郊广为推广;②冬牧70黑麦在越冬期及冬前的生长势优于奥勒岗黑麦草,在需要增加越冬期鲜草供应的饲养单位,采用奥勒岗黑麦草和冬牧70黑麦间条播或混播的方式,可能是冬前冬后均衡供饲,夺取更高刈割量的好方法;③撒播创造了田间植株均匀分布的条件,有利奥勒岗黑麦草和冬牧80黑麦最大限度地利用空间,接纳阳光和吸收养分,从而提高鲜草刈割量,是一种比较合理的简易播种方式。
Raising the production of green feeders and increasing the economic benefits of green feeders are conducive to expanding the planting area of green feeders and promoting the development of the suburban raising industry. The results showed that: (1) The growth and regeneration of Ryegrass in Aolingang were strong, the cutting and utilization period was long, the cutting amount of fresh grass was significantly higher than that of winter grazing 70 rye, Animal husbandry 70 Rye grew better during winter and before winter than the Aolleng ryegrass and was used for sowing or mixed sowing between the Orelgan ryegrass and wintergrass 70 rye in units requiring increased winter supply of fresh grass Way, it may be a good winter winter before a balanced feeding, to obtain a higher mowing a good way; ③ sowing to create a uniform distribution of field plants in the conditions conducive to Oregon ryegrass and winter grazing 80 rye to make maximum use of space , To absorb the sun and absorb nutrients, thereby increasing the amount of fresh mowing, is a more reasonable method of simple sowing.
