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。
Weeds are one of the major factors that severely limit the production of organic vegetables. In this experiment, cauliflower was used as test material to control the growth of weeds and cauliflower. The effects of black ground fabric, black plastic film and wheat straw on the growth of weed and cauliflower were studied. The results showed that the black weeds, black mulch and wheat straw covered the weeds by 88.50%, 83.10% and 56.97%, respectively, and their ability to inhibit annual and biennial weeds was higher than that of perennial weeds. The biomass of black ground cover, black mulch and wheat straw covered cauliflower increased by 17.61%, 18.19% and 0.80% respectively. The production of black ground cover and black mulching cauliflower increased by 14.15% and 16.04% respectively, while that of straw covered reduced by 11.79%. Black cloth on the weed suppression ability is higher than the black film, black cloth can be used in the promotion of vegetable production.
