Why bacillus subtilis is the most popular biofertilizer?

Bacillus subtilis grows fast.It can produce heat-resistant and stress-resistant spores. It can be made into various dosage forms. It can be mixed with chemical pesticides without inactivation, and the mass production process is simple, the cost is low, and the application is convenient and storage.

The effects of Bacillus subtilis on plants are mainly reflected in the following aspects:


1.Nutrition and space competition

The competitive effects of Bacillus subtilis mainly include nutritional competition and spatial locus competition. It can rapidly and massively multiply and colonize in the rhizosphere, body surface or in the soil and in the soil, effectively reject, prevent and interfere with the colonization and infection of plant pathogenic microorganisms on plants, thereby achieving antibacterial and disease-preventing effects.


2.Produce antibacterial substances

Bacillus subtilis can produce a variety of substances with antibacterial and bacteriostatic activities during the growth process, such as subtilin, organic acids, antibacterial proteins, etc. These substances can inhibit the growth and reproduction of pathogenic bacteria, and even destroy the bacterial structure and kill Pathogens. Therefore, Bacillus subtilis has a good effect on the prevention and treatment of diseases such as double rot, root rot and gray mold.


3.Increase crop’s immune system and growth

Bacillus subtilis can secrete active substances, activate plant defense systems, enhance crop immunity and disease resistance, and reduce or eliminate the harm of pathogenic bacteria to plants.
It can also promote the growth and development of a variety of plant seeds, seedlings and roots, and enhance the disease resistance of plants, thereby indirectly reducing the occurrence of diseases. Such as the increase in the formation of auxin such as indoleacetic acid, stimulate crop root development and enhance photosynthesis. At the same time, the materials that are difficult to absorb in the soil are converted into substances that are easy to be absorbed by the crops, and the absorption and utilization of nutrients by the crops are promoted, and the utilization rate of the fertilizers is improved.


4.Induce plant resistances to dieases

Bacillus subtilis not only directly inhibits plant pathogenic bacteria, but also enhances plant disease resistance by inducing the plant’s own disease resistance potential. For example, B. subtilis, a biocontrol agent against rice sheath blight, can induce the activity of enzymes (POD, PPO and SOD) related to disease resistance of rice leaf sheath cells, and achieve disease resistance.

Best Guide- Details to Trimming Cannabis

图片
Trimming is among the most reliable means to adjust and guide the growth of a cannabis plant. If you're seeking to limit the dimension of your plant, promote side branching, delay the onset of flowering, or increase yield, trimming checks all packages. It may feel counterproductive to trim parts of your plant as it expands. However, by pruning ineffective development, you can reroute the plant's energy as well as sources into establishing high-quality flowers. While trimming is sensibly straightforward, it's likewise an ability that comes to be polished and less complicated with the method. These pruning pointers and also tricks should assist in demystifying the procedure. Why do you trim marijuana? Pruning refers to the process whereby tiny, certain sections of the plant are cut to motivate healthy growth. At its most basic level, trimming eliminates development that is harmed, ineffective, or blocking sunshine from reaching budding flowers. Pruning describes the procedure

The benefits of triacontanol on Cannabis growth

图片
Triacontanol is a powerful natural stimulant, it plays an important role during the whole cannabis growth. Excellent ability to help cannabis increasing photosynthesis, roots & flower formation and development. Triacontanol Effect On Cannabis 1.Enhance photosynthesis As we know, photosynthesis is an essential process for all plants. It is the process of turning light into energy and it is. For healthy vegetation marijuana needs over twelve hours of light per twenty-four hour period. As photosynthesis is responsible for over 70% of cannabis production, your goal is to maximize the amount of photosynthetic activity occurring in your crops’ foliage. Triacontanol can be used as a photosynthesis enhancer. When applied to cannabis, it can significantly increase the amount of chlorophyll in leaves, thereby improving the rate of photosynthesis. 2.Promote root development The source of a healthy cannabis plant is a healthy root system. The job of the roots is to absorb the

Best Guide of Common Plant Disease in Garden

图片
For home gardeners, nothing is more frustrating than seeing their work destroyed by pests and diseases. The disease occurs when environmental conditions are suitable for the growth of pathogens on susceptible hosts. Some pathogens attack a variety of plants, while others attack only specific plants. In addition, some pathogens can attack all parts of the plant, while others attack only selected tissues. Many types of organisms cause plant infections , but the top five types of plant pathogens are fungi, water molds, bacteria, viruses, and nematodes. Adverse environmental conditions may also lead to non-infectious diseases of plants, called diseases. Adverse conditions include inappropriate soil pH, nutrient deficiency and toxicity, soil compaction, excessive water content, and herbicide destruction. Plants weakened by adverse conditions may be more vulnerable to pathogens. The following is a brief introduction of several common plant diseases, symptoms and solutions, I hop
