Soil improvement: the role of 28 beneficial agricultural bacteria
At present, soil problems occur frequently. Microbial agents can improve soil, promote crop growth, reduce diseases, etc., but different agents have different functions, so it is necessary to select agents reasonably to achieve the desired effect. Let's take a look at the common beneficial bacteria!

The content of soil organic matter represents the level of soil fertility. It is one of the important indicators to measure the level of soil fertility. It can promote the formation of soil aggregates, improve the conditions of soil physical, chemical and biological processes, and improve the absorption and buffering properties of soil. If the soil organic matter is too low, the soil immunity will be low, and it is easy to harden, acidify, and the crops are easy to get sick.

Soil improvement: symptoms and control of cabbage clubroot
Chinese cabbage clubroot disease is caused by Brassica campestris. After the plant is infected by Chinese cabbage root swelling fungus, its soil roots and underground stems will form tissue swelling tumors. In the case of slight impact, the appearance symptoms of the aboveground parts of Chinese cabbage are not obvious. In severe cases, the absorption of nutrients and water transportation of Chinese cabbage are interrupted, and the aboveground parts wilt due to malnutrition, showing varying degrees of yellowing. If the seedlings are young, some of them will droop, leading to premature death.

Soil improvement: the action principle and influence mechanism of fumigant (Mianlong) on soil
Methyl isothiocyanate (MITC) is the decomposition product of Mianlong. The parent pesticide was applied to the soil before planting and sowing, and rapidly decomposed into MITC in the form of mole to mole in the presence of water. MITC is a multi-purpose fumigant, which is used to resist the activity of plant pathogenic nematodes, weeds, oomycetes and a variety of plant pathogenic fungi through a non selective enzyme inhibition mechanism. MITC can also apply granular product dazomet (trade name LongXin;) Generated in soil. Its half-life ranges from hours to days, depending on environmental conditions. MITC is unstable and may be decomposed into methylamine through thiocarbamate in water. A faster hydrolysis rate is obtained at a lower pH level.
