摘　　要：杂草是严重限制有机蔬菜生产的主要因素之一。该试验以花椰菜为试材,以露地栽培为对照,研究了黑色地布、黑色地膜、麦草覆盖对杂草和花椰菜生长的影响。结果表明:黑色地布、黑色地膜、麦草覆盖对杂草的抑制能力分别为88.50%、83.10%和56.97%,且抑制一年生及一二年生杂草的能力高于多年生杂草。黑色地布、黑色地膜、麦草覆盖花椰菜生物量分别提高了17.61%、18.19%和0.80%;黑色地布和黑色地膜覆盖的花椰菜产量分别提高了14.15%和16.04%,而麦草覆盖的则减产了11.79%。黑色地布对杂草的抑制能力高于黑色地膜,黑色地布可在蔬菜生产中推广应用。Weed is one of the main factors that seriously limited the organic vegetable production. This experiment taken open field culture as control, the effects of black ground fabric mulching, black plastic film mulching and wheat straw mulching on the growth of weed and broccoli were monitored and investigated in Luonan county, Qinba mountains. The results showed that inhibiting ability on weed of black ground fabric mulching, black plastic film mulching and wheat straw mulching were 88. 50% ,83. 10% and 56. 97% ,respectively^and inhibiting ability on annual and biennial weed were higher than the perennial weed. The broccoli biomass of black ground fabric mulching, black plastic film mulching and wheat straw mulching were increased by 17. 61%, 18. 19 % and 0. 80 %, respectivelylbroccoli yields of black ground fabric mulching and black plastic film mulching were increased by 14. 15% and 16. 04% respectively,while wheat straw mulching was decreased by 11. 79%. Inhibiting ability on weed of black ground fabric mulching was higher than that of black plastic film mulching, black ground fabric could be applied in vegetable production.
