研究了杂种披碱草—圆柱披碱草×披碱草(简称Y×P)和披碱草×肥披碱草(简称P×F)及亲本—披碱草,肥披碱草和圆柱披碱草的产量和品质特性。结果表明:Y×P的干草产量为9 168.75kg/hm2,比亲本提高46.8%~52.0%,P×F的干草产量为8 223.15 kg/hm2,比亲本提高18.3~40.7%;两个杂种披碱草叶量较为丰富,茎叶比均显著低于母本。杂种Y×P的营养成分均不同程度的高于其亲本。杂种披碱草在产量和品质特性方面均表现出较高的杂种优势,其中Y×P的杂种优势高于P×F。
Elymus hybrids, Elymus cinerea × Elymus herb (abbreviated as Y × P) and Elymus herbicides × Pseudostellariae grass (referred to as P × F) and their parents-Elymus herb, The Yield and Quality Characteristics of Soda. The results showed that the yield of hay with Y × P was 9 168.75 kg / hm2, which was 46.8% -52.0% higher than that of the parents, and the hay yield of P × F was 8 223.15 kg / hm2, which was 18.3-40.7% higher than that of the parents. Siberian grass leaf is more abundant, the stems and leaves were significantly lower than the female parent. Hybrid Y × P nutrients are different to some extent higher than their parents. Hybrid Elymus hybrids showed higher heterosis in yield and quality characteristics, among which Y × P heterosis was higher than P × F.
