海晏县燕麦与箭筈豌豆混播试验研究

海晏县哈勒景乡燕麦与箭舌笞豌豆的混播实验研究表明:混播草地的鲜草和干草产量分别达到52 000.2和14 100kg/hm2,而单播燕麦人工草地分别为25 400.1和9 100kg/hm2,混播比单播分别高26 600.1和5 000kg/hm2,增产率分别为104.72%和54.94%,ANOVA分析表明,它们之间的差异显著(P<0.05)。另外,混播草地也能提高牧草的品质,混播草地牧草的粗蛋白比单播高2.35%,而粗纤维、粗灰分、钙、磷分别下降1.11%、6.07%、0.24%和0.11%。

Study on Mixed-sown of Oat with Vicia Sativa in Haiyan County

The experiment of mixed-sown of oat with vicia sativa had been conducted in Halejing county of Haiyan county.The results indicated that the fresh and dry forage yield of mixed-sown grassland reached to 52 000.2 and 14100kg/hm~2 respectively,and as for single-mixed grassland,they was 25 400.l and 9100kg/hm~2,which of mixed-sown grassland was higher 26600.1kg/hm~2in fresh yield and 5000kg/hm~2in dry yield than one of single-sown grassland,increased by 104.72% in fresh yield and 54.94% in dry yield.ANOVA analysis showed that the different between yield of mixed-an single-sown grassland was significant(p<0.05).Besides,mixed-sown grassland not only increased forage yield,but also increased forage quality.The content of crude protein of mixed-forage was 2.35%higher than one of single-forage.The content of crude fibre,crude ash,calcium and phosphorus of mixed-forage were lower 1.11%,6.07%,0.24% and 1.11% than those of single-forage,respectively.
