Why we choose chitosan oligosaccharide for our organic farming?

图片
In the application of agricultural production, chitosan oligosaccharides not only make crops grow better and robust, but also has obvious effects in stress resistance and pest resistance. Numerous studies have shown that chitosan oligosaccharides can induce broad-spectrum resistance, enhance the plant’s own defense ability, inhibit the growth of a variety of plant pathogenic microorganisms, and it is non-toxic and can be microbial degradation, and will not pollute the environment. This makes it an important role in agricultural production as a new type of green production.  1. Inducing the production of plant resistance proteins Chitosan oligosaccharides and their derivatives can induce plants to produce resistance proteins against pathogens. Many studies have shown that chitooligosaccharides induce plants to produce chitinase, chitosanase and l-3-glucanase. Chitinase, chitosanase and 1,3-glucanase induced by chitosan o...

Advantages of mycorrhiza in agriculture

What’s the function of Mycorrhiza? Expand the nutrient absorption surface of plants The roots of plants are important organs for plants to absorb water and other nutrients. However, due to various external factors, the growth of roots is still limited to a certain extent, such as hard soil texture, drought and water shortage, which will affect to a certain extent. Absorption of water and nutrients. The epithetized hyphae are hyphae that grow outward from the surface of the plant roots and grow far beyond the roots of the plants. Even in places where the roots of the plants cannot reach, there will be traces of epithelial hyphae, which greatly increases the absorption surface and absorption range of the roots of the plants, thus helping the plants absorb more water and other nutrients. Mycorrhiza increases the absorption of phosphorus by plants Phosphorus is the least easily decomposed and flowing element. The majority of phosphorus in soil is poorly soluble phosphorus an...

What's Mycorrhiza ?

Introduction of Mycorrhiza Excessive dependence on chemical fertilizers can result in the destruction of a large number of beneficial microbial communities in the soil and a decrease in soil activity. To improve the current soil ecosystem with serious damage and improve soil fertility, it is imperative to supplement soil beneficial microorganisms. The application of microbial fertilizer is the most direct and effective method. Symbiotic bacteria are fungi that need to grow with plants, but do not harm plants and they are beneficial to plant growth. The symbiotic bacteria can grow together with the roots of some plants to form a special symbiont-exogenous mycorrhiza, which exchanges substances with each other through the mycorrhiza. Therefore, people call it ectomycorrhizal fungi. It is estimated that plants with mycorrhiza account for about 97% among the known flowering plants in the world. Among them, most arbor species form ectomycorrhizal fungi, accounting for about 3...

What's advantages and disadvantages of crop rotation ?

Advantages of crop rotation 1.Improves soil conditions Crop rotation can make a big difference in soil structure over time. By utilizing different crops, especially those with tap or fibrous roots, it can enhance the chemical, biological and physical structure of the soil. This improves the water holding capacity of the soil, as well as organic matter and nutrients. At the same time,  Trichoderma harzianum  can also be used to improve the soil environment, inhibit soil-borne diseases, control nematodes, slow down the growth and reproduction of nematodes, enhance soil fertility, and create a good growth environment for plant roots. 2.Reduces soil erosion and water runoff Rotating crops can help bring down erosion by improving soil tilth and microbial communities. This creates a more stable soil structure that cuts down on surface runoff. 3.Reduces pests and weeds Insects, weeds and pests can’t survive long without their host. By playing musical chairs w...

Application of chitosan in agriculture

图片
General information Chitosan is derived from chitin which is widely found in nature,such as arthropods(shrimp and crab). The chitin is deacetylated by adding alkali and heating.  In agriculture, chitosan is used as feed additive,plant pathogen antibacterial agent and plantseed surface covering agent, etc. Specification of Chitosan Advantages Control insects and help crop resist diseases. Decompose trace metal elements in the soil. Enhance plant immunity and promote plant health. Improve yield and quality. Compatible with most pesticides and fertilizers. What’s features of Dora Chitosan? 1.High antimicrobial activity One of the most important proprieties of chitosan is its high antimicrobial activity against a wi...
