Pulverizers are machines that pulverize large solid materials to the required size. Pulverizer Machine,Crushing Machine,Milling Machine,Grinding Mill, Grinding Machine JIANGYIN CITY XUAN TENG MACHINERY EQUIPMENT CO.,LTD , https://www.machineryxuanteng.com
Summarizing the symptoms of most vegetables, often with the following symptoms, some monocotyledons misuse herbicides such as herbicides, herbicides and other herbicides, they begin to show signs of stagnation, and buds and sections of meristem appear around 5 days. The heart leaves and other leaves gradually turn purple or yellow, withering for about 10 days; some soybeans are treated with acetochlor before sowing, and the leaves are hypothermia and rainy after emergence, causing the leaves to shrink, the surface rough, the midrib to become shorter, and the single leaves to be heart-shaped or Cup-shaped, dwarfed plants, pale leaves. Some soybeans use sulfonylurea herbicides at the three-leaf stage, such as chlorsulfuron-methyl herbicides, which tend to yellow the leaves, shrink the leaves, turn brown veins and stems into the tissue, and easily break the stems. The point of necrosis, although there may be branches in the late, but late-maturing glutinous, reduced yield; some improper application of glyphosate, mist floating on the vegetables, the whole plant chlorosis, necrosis, dry; some sweet corn Affected by paraquat, the new leaves first wilted and then dried up to the whole leaf; some eggplants and tomato plants were inhibited by the growth point, and the leaves were cup-shaped, mainly by carbamoyl herbicides such as chlorfenapyr. harm.
In order to prevent and alleviate herbicides causing phytotoxicity to vegetables, the following technical measures should be taken care of:
Adjust the medication according to the ecological environment. Herbicides should not be applied when the temperature is below 15°C or above 35°C. When high temperatures, droughts, and strong light are used, weeding herbicides should be avoided. When the temperature is between 15 and 30°C and the soil is soiled, herbicides applied after 4 o'clock in the morning before 10 o'clock in the morning are effective. The use of herbicides in soils with low organic content and high salinity is less effective. Soils with high organic matter content and low salinity have a strong adsorption capacity for herbicides and are generally not susceptible to phytotoxicity.
Select the right medicine and apply it at the right time. At present, there are many types of herbicides. First, we should select drugs for the types of weeds that are easily associated with the local vegetable crops. Second, we must dilute the drugs according to the type of herbicide and the content of active ingredients. Third, we can scientifically mix drugs, but we cannot Random use of indiscriminate use; fourth is to grasp the time of application, such as before sowing, before emergence, after emergence, should strictly distinguish between medication.
Found phytotoxicity and timely remedy. When herbicide harm occurs on vegetable crops, according to local experience, Huimanfeng active liquid fertilizer can be used to alleviate or relieve the phytotoxicity. For example, pepper can be sprayed with 1:800 to 1000 times dilution, and other vegetables can be sprayed 1: 500 times liquid; can spray 1:800 times the harvest No. 1; can spray 0.05% of the 920 solution; can spray PBO and other regulators, both detoxification, but also to repair damaged cells; can increase urea, water fecal Such as quick-impact nitrogen fertilizer raising seedlings.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
The current vegetable injury can not be ignored
Every vegetable production enters the peak season, especially in the summer, when the temperature is too high, vegetable farmers all over the country are often reflected in the process of spraying pesticides, and vegetables are prone to phytotoxicity. Analyze the reasons, first, the climate and environmental changes induced drug harm; Second, misuse of pesticides that are not correct; Third, improper operation techniques, high doses; Fourth, there is no preventive measures to control the spread of phytotoxicity.
