研究了五种播量 ( 60kg/hm2 、12 0kg/hm2 、180kg/hm2 、2 4 0kg/hm2 和 3 0 0kg/hm2 )对家庭牧场“圈窝子”燕麦 (YTY品种 )生长发育及营养成分的影响。结果表明 ,燕麦分蘖的总数和单位面积的株数随播种量的增加呈上升趋势 ,但每株分蘖数呈下降趋势 ;播量为 180kg/hm2 时燕麦青干草产量最高 ( 1650 .78g/m2 ) ,粗蛋白质产量为 2 0 0 .73 g/m2 。燕麦生长发育的规律对不同播量的反映具有一致效应 ,随播量的加大燕麦粗蛋白质的含量呈逐渐降低的趋势 ,粗纤维含量呈逐步上升的趋势 ,而粗脂肪和粗灰分的变化不明显。播量增加不利于燕麦叶量的积累 ,相对较有利于茎量的积累。家庭牧场“圈窝子”内是种植燕麦收获青干草最理想的地方
The effects of five sowing rates (60kg / hm2, 120kg / hm2, 180kg / hm2, 240kg / hm2 and 300kg / hm2) on the growth and nutrient composition of Yukuri (Oryza sativa L.) Impact. The results showed that the total number of tillers and the number of plants per unit area of oats increased with the increase of sowing rate, but the tiller number per plant showed a downward trend. The highest yield of oat hay (1650.78g / m2) Crude protein yield was 2.0 0 .73 g / m2. The law of growth and development of oats had the same effect on the response of different sowing rates. The crude protein content of oat showed a gradual decreasing trend with the sowing rate increasing, the crude fiber content showed a gradual upward trend, while the change of crude fat and crude ash content did not change obvious. Increased sowing amount is not conducive to the accumulation of oat leaves, is relatively conducive to the accumulation of stems. Family ranch “circle nest” is the ideal place to grow oat hay harvest hay
