牧草耐盐力试验研究

Studies on the salt endurance of forage grasses

本文对5种禾本科牧草的耐盐力进行了试验研究,出苗期耐盐力为0.3％～0.4％,生长中期为0.5％～0.7％。在盐碱地试种表现良好,适宜在黄淮海平原黑龙港缺水盐渍区的中度盐渍土地上栽培。

Experiments on salt tolerance of five herbage varieties were carried out at the experimental sites in the water-deficient salinized region of Heilonggang.The results showed that salt-tolerance of the five varieties at their early growgh period was at 0.3 to 0.4 % of soil salt contents, and during their middle growth periods,salt-endurance was increased to 0.5 to 0.7%.The five herbage varieties can grow very well in the salt-affected soils at the test sites.So it is suitable to grow those high salt-tolerant grasses in this region.
