When the garlic farmers planted garlic, this phenomenon of dead trees appeared, and it was also extremely serious. The garlic farmers were suffering. What is the cause of garlic dead tree? How to prevent garlic farmer how to treat it? Let's take a closer look! The main reasons are as follows: 1, heavy There is a virus in the garlic itself, and garlic is repeatedly planted in a piece of land for more than ten years, and internally produced self-toxic and harmful substances. In the process of growth, it also secretes some self-inducing substances harmful to itself, and is left in the soil through the leaching of the ground, root exudates and diseased plant residues, which are planted with garlic for years. These bacteria will increase year by year and inhibit garlic. Growing, severe cases lead to death. 2, garlic carrying bacteria Long-term self-cultivation can lead to the degradation of garlic, the lack of one or several nutrients, and the accumulation of self-toxic substances and diseases. If you do not mix and disinfect the garlic with the pesticide before planting, it is easy to carry the bacteria into the soil. 3. Garlic is infected with germs during growth Garlic white rot, bacterial soft rot, garlic small sclerotium disease, garlic dry rot, garlic root rot and other diseases can cause yellow, rotten roots, dead trees. 4. Unreasonable fertilization leads to soil deterioration The extensive use of compound fertilizers leads to soil acidification, acid-base imbalance, and high salt content; neglecting the use of medium and trace element fertilizers leads to nutritional imbalance and deficiency; using soil fertilizers that are not fully fermented and fermented, farmyard manure causes roots, rooting, etc. Not conducive to the growth of garlic roots. 5, garlic hazards Repeated use and use of unfertilized farmyard manure livestock manure carrying pathogens and eggs, exacerbating the danger of garlic dead. 6, management measures are not in place If the watering is too large and the soil is too high, the soil in the garlic field will be low in temperature and lack of oxygen, leading to dead garlic. 7. Natural factors such as bad weather The high temperature in the early stage of planting and the excessive rainfall lead to the growth of garlic seedlings; the high temperature and high humidity of the soil tend to cause the soil pathogen to infect the garlic one or more times; the low temperature in winter causes the low temperature to cause freezing disasters. Garlic dead tree prevention measures: 1. Reasonable rotation to avoid heavy mistakes It can be rotated with cabbage, onion, and large shed celery. The seriously ill plot should be planted with garlic after 2-3 years. It can also promote the use of large banners for other winter vegetables and play a role in changing crops. 2, garlic selection and disinfection Avoid planting from your own diseased fields, it is best to switch to a disease-free area in different places. The garlic should be selected from a variety of garlic that has no fullness and no mold and mildew. And use metalaxyl, chlorothalonil or donut copper preparations and other seed dressing disinfection. 3. Timely medication to prevent diseases When watering the water after the year, the nurses of the genus Paecilomyces militaris 1000g will be sterilized and disinfected to resist heavy mites and prevent diseases. 4. Add organic fertilizer, microbial fertilizer and medium and trace element fertilizer In the case of bottom fertilizer, the amount of compound fertilizer is reduced, and organic fertilizer, microbial fertilizer, and iron, magnesium, zinc, boron, calcium and other medium and trace element fertilizers are added. Combined with deep fertilization of 30 cm, it not only increases soil organic matter and beneficial microorganisms, but also reduces the deficiency caused by deficiency, and also balances acid and alkali, reduces soil salinity, and improves soil physical, chemical and biological properties. 5. In order to avoid the root cause, acidification hazard and the source of the disease-causing egg infection caused by farmyard manure, soil-fertilizer and animal manure, it must be fully decomposed in advance. Unfertilized farmyard manure, soil fertilizer and animal manure are strictly prohibited from being applied to garlic fields. 6, depending on the weather and soil drought conditions, humidity control, watering On the one hand, the soil moisture is too large to reduce the ground temperature, and the other is easy to lack oxygen, which will seriously affect the development and growth of garlic roots. Focus on soil-borne diseases to protect soil health. Insulin Syringes Needle,Disable Syringe,Monoject Syringe,10 Ml Syringe FOSHAN PHARMA CO., LTD. , https://www.pharmainjection.com
