Platycodon grandiflora [Platycodongrandiflrum (Jacq.) A.DC. ] is a perennial herbal herb and special vegetables, with antitussive, anti-inflammatory, hypoglycemic and other effects. With the adjustment of planting structure, the cultivated area of ​​Platycodon grandiflora increases year by year. Due to the long growth period of Platycodon grandiflorum, the slow growth at seedling stage, the serious damage of weeds and the difficulty of manual weeding. Therefore, controlling weeds becomes an important part of field management. In order to explore the chemical weed control technology of Platycodon grandiflorum, several kinds of herbicides such as dinitroaniline and amide commonly used in vegetables were selected. Field plot experiments were conducted from 2000 to 2001. It is used in 48% trifluralin (produced by Harbin No. 6 Chemical Plant), 50% acetochlor (acetochlor, produced by Jiangsu Kunshan Chemical Factory), and 72% of Dole (metolachlor, produced by Harbin Zhengye Pesticide Co., Ltd.). Transplanted fields of Campanulaceae; acetochlor, Dole, 33% penoxaiin (produced by American Cyanamide Company) used in the field of Campanulaceae, to explore its herbicidal effect and its influence on the safety of Campanulaceae. The experiment was conducted in our school's medicinal botanical garden. In May 2000, weeding trials were carried out on the transplanted fields of flowering bellflowers. The test site was brown loam soil, with an organic matter content of 1.98%, the former was Banlangen, and the area of ​​the plot was 9.75mz. The species of the bellflower was Jiujuan No. 1. The seedlings of the same size that had not germinated in the previous year were transplanted and the soil was sprayed after the planting. In order to screen herbicide suitable for Campanulaceae field, in May 2001, the weeding experiment of Platycodon grandiflorum in the field was conducted. The test site was loam, medium texture, organic matter content was 2.89%, the former was black soybean, and the plot area was 10m2. The varieties of bellflowers were the same variety. Herbicides were treated with soil before seeding. The main weeds in transplanted fields were Echinochloacrus galli, Setaria viridis, Amaranthus restroflexus, Chenopodium alba, and Cephalanoplossegtum. The weeds in weed fields mainly consisted of grasses, amaranth, and amaranth. Abutilon theophrasti, Artemisiasieversiana. Both the transplanted field and the direct seeding field were tested using a single-factor randomized block design with 4 treatments and 4 replicates. The transplanting field was treated with: 1.75 L/hm 2 of trifluralin and 2. OOL/hm/, acetochlor 2.70L/hm2, water volume 750L, spray water control. The weeding treatment in the field was as follows: the acetochlor dosage was 2.50L/hm2, the Dore was 2.00L/hm2, the Shitian supplement was 1.50L/hm2, the water 750L, and a separate spray water control. The use of cell-specific compression compression sprayer, uniform spray in each district. After spraying, observations were made to record the responses of the Platycodon grandiflorum and weeds to the pesticides. After 20, 30, 45, and 70 days after the pesticide treatment, the species and number of weeds in the field and the fresh weight of the aboveground parts were investigated. Each treatment was randomized to 10 points, and each point was investigated. .65m2 and 0.5m2, calculate the control effect and fresh weight control effect of each treatment strain. In the fall, the plant height, single root weight, and plot yield were investigated. The field plots and plant fresh weights were investigated in the field and significant tests were conducted. The results showed that the weed control effect of Platycodon grandiflorum transplanted field, trifluralin and acetochlor was better, and the herbicidal effect was more than 91.21% in 70 days, and it was medium and the effect was more than 81.00%. Campanulaceae live field, acetochlor, Dole effect is better, 45 days in weed control effect of the strain more than 89.5%, fresh weight control effect is more than 90.9%, Shi Tian supplement effect is poor, only 51.9 % and 58.5%. For the observation of the safety of Platycodon grandiflorum, several herbicides did not produce phytotoxicity to Campanulaceae in both tests. through LSR test, transplanted Campylobacter field, spray trifluralin, acetochlor, plot yield were significantly higher than the control; direct astragaloside field, astragaloside, Durocin, plant height, fresh weight are significantly higher than Shi Tian Supplementation and control, Shi Tianbu and control were not significantly different. The reason for Shi Tian's low efficacy may be related to the lower dosage and more soil organic matter content. In order to increase the range of herbicides and herbicides, several combinations of herbicides can be considered to improve the weed control effect. Levamisole (levamisole) is a kind of broad spectrum displacement intestinal worm medicine, is mainly used to drive the worm and worm.Levamisole hydrochloride powder INDICATIONS Levamisole Levamisole Injection,Levamisole Solution,Levamisole Tablet,Levamisole Powder Hebei Kexing Pharmaceutical Co., Ltd. , https://www.kexingpharma.com
