With a reputation of "heat is not dead, drought is not dead, and freezing is not dead," Jingtianke is well-known as the plant A. formosanus. Currently, it is widely used in fields such as roof greening and park landscaping. Especially in terms of roof greening, the use of P. gracilis not only alleviates the phenomenon of “cold winter and hot summerâ€, improves the comfort of living, but also protects the roof from damage caused by high temperature, ultraviolet rays, etc., and is conducive to prolonging the life of the roof. In addition, it plays an important role in purifying air, preventing secondary dust, regulating urban climate, and mitigating the heat island effect. In the process of cultivation and propagation of A. gracilis, its resistance to diseases and insects has always been talked about by growers. In the current published literature, except for the polyphagous beet armyworm, there are few reports of other pests and diseases. The management of weeds has gradually become the most concerned issue in the process of breeding A. sinensis. In particular, the early growth of A. formosanus should be paid attention to in order to reduce the adverse effects of weeds on A. sinensis. When the coverage of S. gracilis reaches 80%, the weeds are difficult to appear in S. gracilis. The weed control technology of A. gracilis is introduced as follows. Pre-planting work 1. Control weeds through fine soil preparation. In particular, the roots of perennial weeds and perennial weeds should be sorted out, otherwise it will be very difficult to manage the turfgrass at a later stage. Such as wild dogroot, dandelion, field bindweed, bowl flowers, water peanuts, thorny vegetables and so on. 2. If you have enough time, you can use chemical herbicides. Lightly run horse water to promote weed growth. When the weeds are basically in the same condition, we use the herbicide paraquat or glyphosate to spray the stems and leaves to kill the weeds. According to the data, the residual period of the two herbicides in the soil is very short, and they are inactivated by soil passivation after 8 to 10 hours of contact with the soil. The fact is that the residual period of paraquat in soil can last for about 10 days, and the residual period of glyphosate in soil is longer, ranging from 20 days to 30 days. During the remaining period of these two herbicides, common planting plants will suffer from different degrees of phytotoxicity. Therefore, after using these two types of herbicides, do not grow Buddha grass within the residue period. Control of weeds after planting 1. For germinating grass weeds, more herbicides can be used, such as large killing crickets, fine quebrachosol, fine stable killing, and high-efficiency herbicides. Weeds. It is highly safe to Sablegrass under the recommended dosage. Even if it exceeds three or four times the recommended dosage, there is still a high level of safety for Buddha grass. We can use the above herbicides to control weedy bermudagrass, thatch and other weeds, as well as older weeds of various grasses such as crabgrass, goosegrass, green foxtail, barnyardgrass, and bluegrass. 2. For germinating broad-leaved weeds, we need to grasp the principle of "except early, except small". Prevent broad-leaved weeds as early as possible to use drugs, weeds are most likely to control around 3 leaves. It is recommended to use a special herbicide "Fargare" water-dispersible granules, 2 g to 4 g per mu, and watering 25 kg to 30 kg of stem and leaf spray. From 7 days to 10 days, the weeds will begin to turn yellow and die. 15 It died completely around days. "Fo Jia Le" is a micro-toxic herbicide, no odor, no drift, toxicity is only equivalent to one-third of the toxicity of salt, for A. sinensis safety. 3. For the Aconite in A. sinensis, the use of the “Falco-Largeâ€-enhanced type can effectively prevent and protect the A. sinensis. Herbicides such as paraquat and glyphosate, which are unsuitable for use, should not be used during the growth period of S. gracilis. Met-tetrachloro-sodium salt, ammonium salt, propionic acid, two or four drops of butyl ester and its related herbicides are not allowed to be used in S. aconitiflora. Common herbicides for control of broadleaf weeds in wheat, rice, and corn fields must not be used in S. mellifera, such as tribenuron (Superstar, Mai Lele), Pentium, Citrobacter, and Fluroxypyr To make it long), bromobenzonitrile, pyrazosulfuron, benzulfuron, nicosulfuron (Yu Nongle) and so on. Shima, clodinafop acid can prevent grass weeds in the grass. Herbicides with a long residual period should not be used in Scutellaria herba, such as metsulfuron, atrazine, and clomazone.
