摘要
目的研究栽培方式对当归地上部分和根的生长动态以及当归麻口病、早薹率、产量的影响。方法以垄作、沟植、覆白色地膜、覆黑色地膜4种不同的栽培方式与平作比较,分析栽培方式对当归干物质积累和生长动态的影响。结果黑色地膜覆盖对当归株高、地上部分和根部干物质积累量的影响最大,其次为白色地膜覆盖。垄作对麻口病的抑制作用最明显,黑色地膜覆盖有提高早薹率的现象。覆黑色地膜的处理产量最高,较对照平作增加4650kg/hm2,增产率达33.4%;覆白色地膜的处理产量次之,较对照增加3372.2kg/hm2,增产率达24.3%,沟植和垄作的增产作用不显著。结论在当归栽培中应大力推广黑色地膜覆盖栽培技术。
Objective To study the effects of cultivation methods on growth dynamics in the aerial part and root of Angelica sinensis and Ditylenchus destructor, rate of early bolting, and yield of A. sinensis as well. Methods Compared with conventional planting, ridge planting, furrow planting, white plastic mulch coverage, and black plastic mulch coverage were used to evaluate the effects of cultivation methods on dry matter accumulating and growth dynamics of A. sinensis. Results The influence of black plastic mulch coverage to growth dynamics of A. sinensis is the biggest, next for white plastic mulch coverage. There is the best inhibition to D. destructor under ridge planting. Black plastic mulch coverage can enhance the rate of early bolting. The treatment of black plastic mulch coverage has the highest yield, which can increase the yield by 33.4% （4 650 kg/hm^2） compared to conventional planting; next for the treatment of white plastic mulch coverage, which increased the yield by 24.3% （3 372.2 kg/hm^2） compared to conventional planting. But there were no significant effects of ridge planting and furrow planting on increasing yield. Conclusion The cultivation methods of black plastic mulch coverage should be brought into wide use in A. sinensis cultivation.
