Effects of Water Retaining Agent on Total Soil Moisture Content and Seed Germination of Perennial Rye-grass
摘要
Abstract
Objective] To research the effects of water retaining agent on seed germination and growth of perennial rye-grass and total soil mois-ture content, and to provide theoretical basis for the water-saving cultivation.[ Method] Under the condition of natural light and shading condi-tion, we compared the effects of different dosages of water retaining agents (0, 3, 6, 9 g/m2 ) on the seed germination growth and matrix water-holding capacity.[ Result] Effects of water retaining agent in different substrates on enhancing soil moisture content and seed germination rate were in the order of composite soil >nutrient soil >loess.When the application dosage of water retaining agent was 6 g/m2 , moisture content of composite soil was the greatest.Germination rate of rye-grass was the maximum.[Conclusion] The application of water retaining agent has sig-nificant effects on the total soil moisture content of different substrates and seed germination of perennial rye-grass, and the effect is the best when the soil matrix is composite soil with 6 g/m2 water retaining agent.关键词
