摘要
试验采用三因素三水平正交设计方法,研究保水剂类型、保水剂用量和氮肥用量在干旱半干旱地区对燕麦(Avena sativa cv.Qingyan No.1)不同生长阶段干草产量和种子产量的影响。结果表明,3种因子在生育期对青燕1号燕麦干草产量影响大小为氮肥用量>保水剂用量>保水剂类型,施加抗旱保水剂,保水剂用量60 kg·hm-2,氮肥用量60 kg·hm-2,可增加种子产量、干草产量、产量构成相关性状指标和种子田经济效益。
Effects of super absorbent polymers type and dosage and the nitrogen fertilizer on oats yield and hay production in different growth stages were studied with orthogonal design with 3 factors and 3 levels at arid and semi-arid region. The results showed that the influence on oats yield decreasing in the following order: nitrogen fertilizer,super absorbent polymers dosage and super absorbent polymers type. The optimal treatment was Soil Conditioner Warer with dosage of 60 kg·ha- 1and 60 kg·ha- 1nitrogen fertilizer which can increase the yield,yield performance and economic benefit of Avena sativa cv. Qingyan No. 1.
