How to solve the problem of garlic?

One: What is heavy

The same or the same crop is continuously planted in the same plot for three or more years and is called "heavy" in cultivation. (One year is called Xinyi, two years is called Yingxi). Heavy cropping is an important cause of the growth of many crops, the increase in disease, the decrease in yield, and the decline in quality.

Second, the reasons for the obstacles

1. Nutritional disorders

The same or the same crop has certain nutrient requirements, and the plants do not like the unwanted elements that are absolutely not absorbed. Plants are not as useful to humans as they are, and they are useful for the health. Lead to the lack of certain elements in the soil, excess of some elements, leading to nutritional imbalance.

2, soil accumulation

On the one hand, the soil accumulation caused by the residues caused by herbicides and pesticides; on the other hand, the soil accumulation caused by the toxins secreted by the crops can degrade soil fertility, hinder the absorption of nutrients, and underdeveloped roots.

3, the amount of soil bacteria is large

The crop seeds themselves carry harmful bacteria. Due to the long-term accumulation and reproduction of heavy crops, they cannot be effectively decomposed and digested, and the number of original pathogens in the soil is accumulated for a long time.

4, fertilization is not balanced

Due to the unscientific long-term fertilization, soil compaction, acidification and salinization are serious. Excessive phosphate fertilizer and metal ions in the soil solidify in the soil to form a knot; excessive application of nitrogen fertilizer, excessive nitrogen will be oxidized to nitric acid, leading to acidification of the soil; excessive application of fertilizer or long-term application of chemical fertilizer will lead to soil salt Water staining.

Three: the performance of heavy obstacles

1. The accumulation of soil and the amount of germs caused the occurrence of soil-borne diseases, which eventually led to the death of dead trees and low survival rate.

2, imbalance of nutrients will lead to: crop growth and development, affecting the quality and yield of crops

3, uneven fertilization: compaction: soil agglomerate structure damage, poor permeability, crop roots are not developed, physiological obstacles and dead tree rotten seedlings and other soil-borne diseases are serious; acidification: lack of physiological diseases such as calcium, magnesium, boron. It also limits the survival of nitrogen-fixing bacteria; salinization: the roots are short and underdeveloped, the leaves are rigid, the plants are short, and even water shortage is caused.

Four: prevention and treatment of heavy obstacles

1, squatting: also called rotation, can effectively avoid heavy obstacles, but its operation is troublesome, resulting in large changes in the local planting structure, and is not convenient to manage.

2, grafting: can effectively avoid the phenomenon of dead tree rotten seedlings, but it is only anti-heavy, can not solve the heavy sputum, and its operation is difficult, there are certain limitations, some crops can not be grafted, its grafting survival rate is also low.

3, sterilization: Some places, especially in greenhouse areas, use fungicides or shacks to kill bacteria in the soil, but this method can only kill surface bacteria, the bottom temperature of the soil can not reach, killing, and this method Not only will the harmful bacteria be killed, but also the beneficial bacteria will be killed, and the problem of soil accumulation will not be solved.

4, fertilization: increase the application of organic fertilizers and biological fertilizers, but these living conditions require harsh living conditions, use is more troublesome, often can not fully play the effect, and is not conducive to long-term storage, affecting sales time. It is also impossible to solve the problem of soil accumulation.

Five: professional anti-heavy weight - Wanmu Kang

First, product features:

The product is mainly made up of microbial metabolites, photosynthetic super-carbon and bee-quality, and is produced by high-concentration double chelation technology with high activity humic acid as carrier.

Second, the mechanism of action:

a: The core technology of this product is a microbial metabolite containing a variety of polypeptide enzymes, active molecules, amino acids, etc., which can promote the reproduction of bacterial flora in the soil, and can decompose soil accumulation, improve crop living environment, and effectively prevent and solve soil transmission. The hazards of the disease, and the characteristic component of the bee seed can clear the crop conduit, promote the absorption of nutrients, promote cell division and activation, and make the crop change machine.

b: The polypeptide and active molecules contained in this product can decompose the solidified phosphorus and metal trace elements in the soil into ionic state, let the crops re-absorb and utilize, and contain certain trace elements to ensure the supply of crop nutrients.

c: This product also contains photosynthetic super-carbon, which is small molecule carbon, which enhances the absorption of carbon by crops from the roots. And this product is based on organic matter, and can also supplement the organic matter content in the soil in a small amount.
