不同覆盖方式对盐碱原土土壤水分和油葵产量的影响
Effects of Different Mulching Methods on Water in Original Saline Alkali Soil and Helianthus annuus Yield
摘要
Abstract
[Objective]Effects of different mulching methods on soil water and Helianthus annuus yield were studied.[Method]The field management practices including plastic film and straw dual-mulching(PSM),plastic film mulching(PM),straw mulching(SM)and conventional tillage(CK)were designed to study their effects on soil water use efficiency (WUE) and crop yield.[Result] In the seedling stage of H.annuus at the topsoil (0-30 cm),the soil water content in the treatment of PSM was lower (P<0.05) than that of PM,SM and CK,respectively.However,the water content in PSM treatment in the squaring stage was higher (P<0.05) than that in the treatments of PM,SM and CK,respectively.Plant height and leaf number of PSM treatment were 112.3 cm and 27.0,which were significantly greater than other treatments(P<0.05).The yield of H.annuus in the treatment of PSM was 35.45%,120.15% and 87.80% higher than that in treatments of PM,SM and CK (P<0.05).The water use efficiency of PSM treatment increased by 10.80% and 32.71%,respectively,compared with the treatments of SM and CK.[Conclusion]Using plastic film and straw dual-mulching to plant H.annuus in original saline alkali soil can raise the production potential of natural precipitation and promote water-saving production.关键词
