不同海拔烟区覆膜天数对土壤温度及烟株生长的影响
Effects of Different Mulching Days on Soil Temperature and Tobacco Plant Growth in Different Altitude Area
摘要
Abstract
[Objective] The aim was to study the effects of different mulching days on soil temperature and tobacco plant growth in different altitude area of Tongren Area. [Method] Taking altitude as primarily factor, and covering film and film period as the secondary factor, the influences of different mulching days on growth, development, yield and output value of tobacco in the altitude of 600(in Longquan) , 800(in Chuanyan) and 1 000 m(in Gaoshan) in Dejiang Country of Tongren Area were studied by randomized block design. [Result] The results showed that at the tobacco area of the altitude of 600 and 800 m the best film uncovering time was about 35 days after filming, which promoted tobacco plant growing quickly, and improved tobacco leaves' yield and output value. At the tobacco area of the altitude of 1 000 m, the best film uncovering time was about 50 days after filming, which tobacco leaves' yield and output value increased, and quality was good. [Conclusion] The study provides a reference for promotion of flue-cured tobacco mulching cultivation at different altitude area of Tongren Area.关键词
