The Investigation And Medicament Prevention Of The Advantage Plant Of Weed In Turf In Huaibei Area Of Anhui Province

As a new industry, lawn are developing rapidly, and the mostly problem faced is the damage of weed. For the absence of appropriative medicament and technique in the market, the harm of weed becomes prosperous. At the same time, the expenditure increased quickly, and insect pest arises, which affect the growth, landscape and the function.Focus on the study of lawn, present paper study the advantage plant and chemical technology based on the investigation of the arisement and harm in Huaibei Area, Anhui Province. "M" shape sampling method was used, every sample 1 m~2 ; then write down the kind, amount and covery. At last calculate the emergency frequency and damage index, and make sure the seed species and their community. There are two treatment level, three replication, and every region area was about 10m~2.The results indicate that there are more than 100 weed species in Huaibei Area, Anhui Province. Among them, composite was 21 species, which was 21 percent; Cruciferae and butterfly faculty was 6 species respectively, which was 6 percent; labiate and euphorbia was 5 species respectively, which was 5 percent; amaranth and sedge faculty was 4 species respectively, which was 4 percent. There 9 advantageous weed species, which were spiciness, goose grass, shepherd's-purse, etc. The results indicated that Flazasulfuron, Fenoxaprop-P-ethyl, 2,4-D butylate, bentazone and Xiaoza are safe for Manila lawn, and especially Flazasulfuron and Xiaoza, which could reach 85 percent of prevention for Alligator Alternanthera, Nurgrass Galinggale,Large Crabgrass and goosegrass.The harm of weed in lawn mostly due to the improper treatment and unscientifical management. The problem of weed mostly occurred in prophase, which because that in this period there are so many weed seed in soil, and impurity and interspace in the lawn; additionally, too much water and fertilization also would accelerate the growth of weed seed. In another aspect, lawn could provide the good space for recreation, which connected tightly with people health.The urgent proplem which need be solved are the deficiency of the careerman of plant protection, the vacancy of lawn maintenance standard and distemperedness of technology and responsibility trusteeship of lawn maintenance. So in the future, our study will focus on the above aspects, which could provide perfect technology for the lawn safety.
