夏莜麦区饲草燕麦复种技术探讨

Sequential Cropping Technology of Forage Oat in Summer Oats Area

莜麦—饲草燕麦和饲草燕麦—饲草燕麦作物组合的燕麦复种试验结果表明,在夏莜麦区实施一季籽实、一季饲草和两季饲草的燕麦复种方式均可行。莜麦—饲草燕麦作物组合,第1季种植早熟材料185、第2季种植皮燕麦品种XZ04170,同一地块上可产莜麦籽实2 648.70 kg/hm2、鲜草16 443.30 kg/hm2;饲草燕麦—饲草燕麦作物组合2季都种植皮燕麦品种XZ04170,共产鲜草34 751.7 kg/hm2,第2季产草量达到第1季产草量的89.81%。

Results of sequential cropping technology of the combinations of buckwheat ＋ forage oat and forage oat ＋ forage oat showed that,in summer oats area sequential cropping method of a crop of seeds plus a crop of forage or two crops of forage were feasible.Seeds 2 648.70 kg/hm2 and grass 16 443.30 kg/hm2 respectively could be got by planting the early mature variety 185 as the first crop and skin oats variety XZ04170 as the second crop in naked oats ＋ forage oats,combination;The grass output could reach 34 751.7 kg/hm2 by only planting the same skin oats variety XZ04170 in two crops in the forage oats ＋ forage oats combination.The grass output in the first combination was 89.81% of the second.
