Chicken manure is the chronic poison for orchards!
Grape winter fertilizer is the basis for the harvest of grapes in the coming year. When it comes to winter fertilizer, many people will think of chicken manure. In the previous years, chicken manure was used as raw material for organic manure to produce high yields for grapes, and Hunan, Changsha, Huaihua and Changde. The garden has a strong dependence on organic manure in chicken manure, but it has been found in the past two years that both the unprocessed chicken manure and the organic manure produced from chicken manure (incomplete fermentation) have caused a series of problems for the grapes. The possibility that, for example, nematodes ravaging the grape fields, accelerating soil acidification, white rot, falling grains, and other issues, directly caused huge economic losses to the grape growers. Unfortunately, many growers still do not realize the chronicity of chicken manure. The hazards of cancerous tumors, the following to understand the chicken chicken manure on the chronic poisoning effect.
There are five major disasters that can easily be caused by using chicken manure in vineyards:
One: burning root, burning seedlings, smoked trees, dead plants
After using the chicken manure that has not been thoroughly fermented in the grape garden, the soil temperature is measured by inserting the soil into the soil. The soil temperature is obviously high. This kind of high temperature easily burns the roots of the grapes. When you look closely, you can see the white roots turning black and wilting. Damage causes the grapes to absorb fertilizer and moisture. The potential safety hazard of using chicken manure in winter and spring of greenhouses is the biggest, because the temperature in the greenhouse is high, chicken manure fermentation will emit a lot of heat, resulting in burning root phenomenon; the vineyard uses chicken manure in winter and spring, before and after the root dormancy, Once roots are burned, it will affect nutrient accumulation and flowering and fruiting in the coming year.
II: Salinized soil in the shed, reduced production
The use of chicken manure for successive years has left a large amount of sodium chloride salt in the soil. A large number of field surveys found that the chicken manure contained an average of 30-40 kg per kilogram of salt, and 10 kg of salt per acre had severely restricted soil permeability and activity. Cured phosphate, potassium, calcium, magnesium, zinc, iron, boron, manganese and other important elements, the emergence of abnormal growth of vines, sparse flower buds, fruit production and other false phenomena, which significantly restricts the increase in grape yield and quality. At the same time, the utilization rate of fertilizers has plummeted. The utilization rate is less than one year in a year, and the amount of fertilizer used is more than one year. It obviously increases the input cost but does not increase the output.
III: Acidify the soil and induce various rhizospheric diseases and virus diseases
Because chicken manure has a pH of about 4 and is extremely acidic, it will acidify the soil. Many garden soils in Ji County, Hunan province are acidic, causing chemical trauma and severe damage to the base and root tissue of the stem grape, causing large amounts of virus to be carried by the chicken manure. Bacteria, soil-borne pathogenic bacteria, and viruses provide opportunities for entry and infestation. Diseases can develop if humidity and temperature are reached. The use of chicken manure that is not thoroughly fermented can easily cause wilting of plants, yellow dryness, atrophy not long, no flowers and fruit, and even death, resulting in ulcer disease, white rot, ear dry, etc., stem rot, root rot, Spike blight becomes the most obvious sequela of using chicken manure;
Four: breeding root knot nematodes
Chicken manure is the campsite and hotbed of root-knot nematodes. The number of eggs carrying Meloidogyne spp. is 100 per 1000 g. The nematode eggs in chicken manure are easy to hatch, multiply overnight by tens of thousands, and the nematodes in the soil The incidence of plots with chicken manure increased 500% or more. Nematodes are extremely sensitive to chemical agents. After application, nematodes quickly migrate to the depths of 50 cm to 1.5 meters underground, so it is difficult to cure them. Especially for the old sheds over 3 years old, root-knot nematodes are one of the deadliest hidden dangers.
V: Bring antibiotics, affect grape quality and safety
The feed contains a lot of hormones. The chicken droppings from the chickens fed on the feed contain a lot of antibiotics. These antibiotics carry chickens and feces into the soil, seriously affecting the quality of the grapes and the safety of the grapes. The grapes may not be able to buy a good price and may give it to oneself. Get trouble.
Medical protective clothing refers to the protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning personnel, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its function is to isolate germs, harmful ultrafine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
