不同种植模式对棉田土壤物理性状及产量的影响
Effects of Planting Patterns on Soil Physical Properties and the Yield of Cotton
摘要
Abstract
Objective]In order to investigate the potential of jujube intercropping cotton agricultural pro_duction complex systems and improve economic efficiency of complex system.[Method]Research the effects of planting patterns and irrigation volume on soil physical properties and yield of cotton through two years of field trials,based on three cropping patterns and four irrigation amaunt through two years of field trials.[Re_sult](1)Under the M1 mode,0 —40 cm soil layer soil moisture was low; 60 —100 cm soil moisture was low under 250 m3 ∕667 m2 irrigation volume.(2) At soil layer of 0 —20 cm,with the increase of irrigation water, the soil bulk density increased in different planting patterns.M1 planting patter,the fluctuation of surface layer and soil deep layer bulk density was relative heavy,however,in M3 planting pattern,at different soil layers it was relatively steady.(3) Under the same pattern,the highest cotton yield came out under the 300 m3 ∕667 m2;by the same amount of irrigation treatment,the highest yield was M3 model,the highest economic efficiency was M2 model.[Conclusion]Planting cotton away from 1.0 m from young wild jujube in combination with ir_rigation water volume 300 m3 ∕667 m2 was not only conducive to maximize production potential,but also benefi_cial to enhance single cotton yield,thus improving the economic efficiency of complex systems.关键词
