Introduction:
The Portable Magnetic Separator is the most popular model which used in seed, grain, flour mill plant to remove magnetic materials such as iron pieces, iron screws, iron nuts etc. it is portable, because it has very small size and easy to put on other equipment. it has a magnet cone which has high magnet strength, all magnetic materials will stick on the cones when grain passing by. so you should clean it after use for a while.
Features of Portable Magnetic Separator :

The cause of the analysis of seed bacteria is one of them.
Seed carrier is the main route for long-distance transmission of diseases, and it is also the primary source of infestation of new vegetable fields. Seeds that are not subject to quarantine can be transported at random to expand the scope of disease to a certain extent; the disinfecting treatment of seeds is not paid attention before sowing. Disease development has brought favorable conditions.
Heavy sorghum cultivation accumulates bacteria in the soil and aggravates disease occurrence.
The multiple cropping index in protected areas is high, and it is difficult to change crops in rotation. Continuous cultivation of annual crops increases the content of pathogenic bacteria in the soil. In addition, the microclimate with high temperature and high humidity in protected areas is suitable for disease occurrence and causes serious diseases.
Improper cultivation methods and unreasonable irrigation methods have created conditions for the occurrence of diseases.
According to the survey, the average incidence of flat mulberry cultivation is higher than that of high ridge cultivation, and the incidence of land with large flooding or flooding times is also heavier.
Premature colonization is also one of the causes of dead peppers.
In recent years, some vegetable farmers have only cared for early and blindly advanced sowing dates and planting dates. In particular, last year in our province Changle Ditch and other places, most of the vegetable farmers have been planted in mid-July, due to strong light, hot temperatures, high air humidity, coupled with excessive planting, resulting in severe yellow leaf dead trees.
Infection during the growth period.
According to investigations and studies in recent years, there are currently 2 types of 3 pathogens that cause dead tree disease in pepper in Shouguang City.
One is bacterial infestation, such as bacterial wilt.
The disease began to wilt from the top of the branches of the leaves, accompanied by wilting and blighting of the entire leaf, and the disease duration was short. The appearance of the diseased stem was not obvious, and the vascular bundle in the longitudinal stem turned brown, and the milky white mucus overflowed from the cross section.
The other type is fungal diseases, which mainly include three kinds of wilt disease, epidemic disease and sclerotinia disease.
In the early stage of wilt disease, the lower leaves were largely exfoliated, and the cortex of the stem base that was in contact with the ground was rotted, and the shoots and leaves of the shoots quickly withered. Epidemics can occur throughout the growing period of peppers and are most vulnerable to fruit setting. In the adult phase of disease, the diseased part forms long strips. The sick and healthy borders are obvious, the lesions are sunken or slightly contracted, and the diseased leaves are wilted and defoliated. The Sclerotinia sclerotiorum disease causes damage to stems or branches and branches. When the humidity is high, the disease minister produces white mycelium, and at the later period, the black rat fecal nucleus can grow, and finally the plants die.
The epidemic disease has the highest incidence, accounting for about 70% of the dead tree fields. The disease has a fast onset, especially after high-temperature watering, and can be extensively affected within a few hours. Not only the seedlings can be susceptible, but also the stems of adult plants. The leaves and fruit can be susceptible to disease, and the transmission speed is also faster, which is more harmful.
Followed by root rot, accounting for about 20% of dead tree fields, generally after the fruit is beginning to wilted, brown root lesions occur in the main root, the root skin is easily stripped, so that the pepper fruit can not be normally mature, root rot disease has a long course, difficult to find early Characteristics, once it is too late to find, so early defense is crucial.
The incidence of bacterial wilt and blight is very small, but bacterial wilt is a bacterial disease. It not only spreads quickly, but also has a short course of disease, dies quickly, and is often a devastating disaster.
Specific prevention and control measures against dead peppers are to prevent and control these diseases at the same time. Prevention and control must first understand the characteristics of these diseases: These diseases can be transmitted by water. The pathogens are mostly in the soil and can infect the roots of the peppers in the soil. Like the disease and bacterial wilt, they can also invade directly. The upper organs of stems and leaves that are dyed with peppers can be said to be capable of infecting peppers in all directions; root rot and epidemics can infect peppers at the seedling stage, and can also infect peppers at the adult stage, which can be said to be in chili It can be infested throughout the growing period.
In the current production practice, some vegetable farmers use grafting to prevent dead trees, and some use chemical fumigation to treat the soil, which has advantages and disadvantages. After investigation and research and practical tests, relevant experts summarized a set of techniques for the prevention and treatment of dead trees in chili peppers, and they are introduced here. This method is based on the characteristics of the whole growth period of dead cedar bacteria, and it adopts a comprehensive prevention and control strategy from the underground to the ground, prevention from the next species to the whole growth period after harvest. Its specific approach is:
Although there are more and more farmers buying finished seedlings in the past few years, most farmers still raise their own seedlings. Nursery should pay attention to their own seedbed clean, the first choice is the new soil, followed by the seedbed to eliminate the bacteria, can be used against the enemy and other agents.
Transplanting the appropriate amount of medicine to Xiangnong 4, when transplanting acupuncture points, 1000 to 1500 grams per acre, before the application can be mixed with soil mixed medicine to facilitate the use.
One month after the intensive irrigation and colonization, the roots should be irrigated with the above agents. The dilution factor should be 600-800 times. It can also be sprayed on the leaves.
Regular spraying and regular spraying precautions can be done with a broad-spectrum fungicide Dasheng-M45, or Xiangnong No. 4 800 times, once every 7-10 days.
Of course, if we can rationally and comprehensively apply biological bacterial fertilizers and fundamentally improve the soil environment, we can effectively prevent the death of peppers. For example, after the planting, Haili Soil Conditioning Agent (6 liters per mu) or live EM bacteria and fertilizer fields Biobiotic fertilizers, etc., adhere to better use.

Causes of Dead Planting of Pepper and Its Control Measures
Dead pepper is the most troublesome thing in the production of chili peppers. The loss caused to pepper farmers in recent years is not small. Some peppers are even forced to switch to producing Other vegetables because of dead trees. So what's the cause of dead pepper and how should it be prevented?
