| 摘 要： | 在作物生产中,不但要高产,稳产更为重要,因为大多数作物种植者处在易变多样的环境中。生产实践证明,在易变多样的生态系统中,靠单一基因型作物种群来达到既高产又稳产的目的是很困难的。根据生物多样性稳态学原理可知,若将同种作物的两个或两个以上纯系品种或品系按一定的比例组成混合种群,肯定能够提高作物群体产量的稳产性。有关作物双基因型混合种群的稳产效应研究,国内外已有许多研究报道,但大多为抗病稳产方面的研究,有关其它逆境方面的稳产效应研究报道较少。1989～1993年我们利用耐盐性不同的小麦品种,在山东省鲁北地区的盐碱土地上…

| Abstract: | The stable effect of binary genotypic mixed population were studied using different wheat cultivars with different characteristics in salt-resistance in Binzhou prefecture of north Shandong province during 1989-1993.The result shown that the stable effect in the biomass and grain yield of binary genotypic population were significantly better than mono-genotypic population under the condition of piebald saline-alkaline soil. |
