Garlic field weeding is stressful

Garlic is one of the favorite vegetables for consumers and is edible all year round. Nowadays, the rural labor force is mostly elderly people. In order to reduce the labor intensity, pesticides are often applied before and after garlic planting to control weeds. Due to the lack of knowledge of the drugs, the occurrence of phytotoxicity in the application of herbicides is not uncommon. Therefore, it is necessary to put safe production. The first place to weed in the garlic field. Linyi Fertilizer Network Copyright

In the process of garlic production, the biggest headache for farmers is the accompanying weeds. If it is raining after sowing, the weeds are extremely rapid. It is a harmful situation. First, there are many weed species, monocotyledonous weeds and dicotyledonous weeds are mixed; second, garlic has a longer growth period, and the development speed is slower in the early stage, while weeds grow earlier and the growth process is often faster than garlic; Third, the amount of occurrence is large, and the dens density of some field weeds may be greater than the density of garlic seedlings; the fourth is that weeds have a long period of damage, from cultivating to harvesting and symbiosis with garlic, vying for light, competing for fertilizer, fighting for water, and striving for living space; Lighter can reduce the yield of garlic by 20%~30%, and reduce the yield by more than 50%. In order to overcome grass damage and increase garlic production, comprehensive measures such as agriculture and chemistry must be adopted to prevent and control safety as early as possible.

First, use agricultural control to reduce the weed base. Weeds rely on seeds and residual stems and leaves to breed garlic. The production must be prevented by agricultural measures. One can implement water and drought rotation, and the other can be rotated with cotton, oil, beans and other crops. The high temperature dries the weeds, the fine soil preparation, the soil soaked grass, the fourth is to clean the weeds around the field, the fifth is to clear the ditch, reduce the water level, and improve the environment that inhibits weeds.

Second, distinguish different grasses for chemical weeding. For the field dominated by monocotyledonous weeds, before the emergence of garlic, 48% of Fluramine EC 100-150 ml per acre, or 48% of alachlor EC 200 ml, 33% Le Ling EC 200 ~ 250 ml, 50% acetochlor EC 90 ~ 120 ml, 50% dichlorfen WP 120 ~ 140 g, respectively, 50 kg spray with water. For the dicotyledonous broadleaf weeds, which are mainly composed of mother-in-law, piglet and sorghum, before the emergence of garlic, 50% isoprolongol is used in 150-200 g per acre, and 50 kg of water is sprayed. For monocotyledonous, dicotyledonous weeds and sedge mixed, after the sowing of garlic to the emergence stage, or before the 2nd to 1st leaf stage of garlic 2 leaves, use 48% or 72 ml of 24% oxyfluorfen emulsifiable concentrate per acre or 37% of oxacillin and acetochlor EC 110~180 ml; or after sowing of garlic to the vertical needle period, use 40% of oxalicin oil 100-140 ml per acre, spray 40~60 kg respectively. For weed-mixed garlic fields, 25% of oxalicin oil 39 ml + 50% acetochlor EC 50 ml, or 24% oxyfluorfen emulsifiable concentrate 10 g + 33% pendimethalin WP 20 grams of powder sprayed with 40~50 kg of water has good herbicidal effect and is safer.

Third, pay attention to improve the control effect. In the process of weeding, the effects are very different due to weather changes and technical measures. Therefore, in the operation technology, we must grasp the following points: First, we must choose the former weed field with few weed bases, try to remove the weeds before planting; second, the field sensation should be good when spraying, if the lyrics are insufficient or weeds If it is too large, it is necessary to increase the dose of medicinal water appropriately; the third is to avoid high temperature and rainy days; the fourth is to spray a herbicide such as volatile trifluralin, which should be sprayed with soil and soil while spraying; It is not advisable to use sulfonylurea herbicides such as chlorsulfuron or metsulfuron in the garlic field to avoid phytotoxicity and leave residual poison to the crops.
