Effect of Cultivating Natural Keeping Digitaria in Citrus Orchards

对柑橘园蓄生马唐草栽培效应进行了研究。结果表明,桔园蓄生马唐草在夏季高温季节土层月平均温度比对照温度低5～6℃,极端高温可降低14℃;8月高温干旱季节可提高相对空气湿度5.1%,土壤含水量可提高2.1%。蓄生马唐草栽培可以有效改善生态环境,降低春夏高温季节土壤表面及土层温度,提高土壤的含水量和空气相对湿度,提高水土保持能力,有利于柑橘的生长发育,提高其产量与品质。

Effect of cultivating natural keeping Digitaria in citrus orchards was studied. The results showed that the average monthly temperature of soil horizon was lower 5℃-6℃ compared to the control in summer, and the highest temperature was decreased by 14℃, air moisture and soil moisture content was increased by 5.1% and 2.1% respectively in August through cultivating natural keeping Digitaria in citrus orchards. The results showed that environment, soil moisture, air moisture content, as well as water conservation were all improved, and the temperature of soil horizon was reduced in spring and summer which temperature was very high through cultivating natural keeping Digitaria, resulting in increase of growth and development, quality and quantity of citrus fruit.
