organic bamboo fungusThe organic bamboo fungus was a common mushroom. It tasted refreshing, crisp, and refreshing. It was rich in nutrients such as protein, protein, and protein. It was known as one of the Eight Treasures of Grass. Bamboo fungus was especially rich in Glutinic acid, which could be used to make fresh soup. After picking, the bamboo fungus would usually be air-dried to retain its original flavor. After soaking, the bamboo fungus regained its vitality. Its snow-white surface was filled with voids, allowing it to absorb the soup well when making soup, making it taste even more delicious. Gutian, Fujian Province was a well-known bamboo fungus producing area in China. The quality of the bamboo fungus produced was high. There were many brands of organic bamboo fungus on the market, such as Jintang and Member's Mark. In addition, organic bamboo shoots could also be purchased on some e-commerce platforms, such as Jingdong and Taobao.
organic chloridizing reactionThe chloration reaction of organic matter was the process of introducing a Cl-atom into the molecules of organic compounds. The common chloration reaction method was as follows:
1. Using SOCl2 or PCl/PClwas the most common method of chloridizing alcohol. The reaction mechanism using phosphorous acid as a source of chloridizing was similar.
2. Ph P/NCS (or (ClCl
3. Using MeLi then TsCi/LiCi, this method uses an alkyi lithium reagent as a base, which will form an oxygen negative ion, suitable for alcohol compounds with large steric hindrance.
4. Through TsCl-NaCl2, this method had an advantage for allylalcohol and had a good regional selection.
5. Relatively uncommon method:
- Using the combination of DPS and DPS, it had a good selectively for allylalcohol and benzylalcohol, and other saturated alcohol was inactive under these conditions.
- There was also a method similar to the Mitsuobu reaction, which would result in the reversal of the chirality center, which was applicable to both allylalcohol and saturated alcohol.
In addition, the industry could also directly use Cl2 for the reaction. In organic compounds, there are generally two types of substitution and addition chloration. For example, the hydrogen in the molecular substitution of the chloridizing reagent could be replaced by the chloridizing reagent to form the chloridizing reagent. In the presence of an iron catalyst, the hydrogen in the chloridizing reagent could be replaced by the chloridizing reagent to form the chloridizing reagent. In addition, the chloridizing reagent could be used to form the chloridizing reagent, such as the chloridizing reagent, to form the chloridizing reagent.

About organic farmsAn Organic Farm
I once had the opportunity to visit an organic farm, which was an extremely interesting and educational experience.
When I first arrived at the organic farm, I was immediately attracted by its natural beauty. The farm was like a large green paradise. There were neat vegetable plots everywhere. The vegetables growing there were very fresh and healthy. For example, the tomatoes were bright red, as if they were little red lanterns hanging on the branches. The cucumbers were long and straight, with a fresh green color that made people feel full of vitality.
In addition to vegetables, there were also various livestock on the farm. The chickens were walking around freely in the yard, looking for food here and there. The cows were grazing leisurely in the pasture. They looked very docile, and their mooing seemed to be a unique symphony on the farm.
The management of this organic farm is very scientific. The farmers do not use chemical fertilizers and pesticides at all. Instead, they use natural compost and biological pest control methods. For example, they will use some beneficial insects to control pests, which not only protects the environment but also ensures the purity of agricultural products.
This visit to the organic farm made me deeply understand the importance of organic agriculture. It not only provides us with healthy food but also protects our ecological environment. I hope more farms can adopt organic farming methods in the future.

organic fertilizer disinfectantThe following are some products and methods related to the fermentation of organic fertilizers with sterilization effects:
- Youjunkang organic fertilizer starter: During use, it has the effect of raising temperature, removing odor, eliminating pests, weed seeds, and increasing nutrients. It indirectly plays a role in sterilization.
- Rapid fermentation tank for organic fertilizer: It uses advanced fermentation technology. In the process of rapid fermentation of organic fertilizer, it can ensure that the organic fertilizer meets the national standards through strict quality control system. To a certain extent, it can suppress harmful bacteria. It is suitable for the fermentation of chicken manure, pig manure, cow dung, sheep manure, quail manure and other raw materials.
- On the market, there were products such as fermented organic fertilizer inoculants (livestock manure organic fertilizer inoculants for fruits and vegetables, soil improvers, straw microorganisms) and 32.3 yuan microorganisms inoculants (B. subtils water fertilizer inoculants, EM bacteria). These inoculants helped to ferment organic fertilizers, and the beneficial microorganisms in some products could suppress harmful bacteria during the fermentation process.
- Self-made fermented liquid: Use 1 kg of brown sugar and 25 grams of yeast powder for making noodles to melt in warm water, add 10 kg of clear water, and put it in a place with a temperature of 20 - 35 degrees to ferment for about a week (success is achieved when there is a fragrance of wine). When fermenting organic fertilizer, it can improve the soil environment and reduce soil pests and diseases. If possible, it would be better to add 0.2% of B. subtils or EM bacteria solution.
- [em] Compost fermenting bacteria: When fermenting vegetable leaves and weeds to make organic fertilizer, it can achieve heat and odor removal, eliminate bacteria eggs and weed seeds, thereby improving fertilizer efficiency and improving soil.
- Compound organic fertilizer starter: It can be used to ferment farmyard fertilizer. During the fermentation process, it suppresses harmful bacteria through the action of beneficial microorganisms. It was sold in general agricultural stores or online.
When using these starter cultures or related fermentation methods, they can be selected according to actual needs, such as the type of fermentation raw materials, the scale of fermentation, and other factors.

The difference between organic fertilizer and bio-organic fertilizer in northwest ChinaThe organic fertilizer mainly comes from plants and (or) animals. It is a carbon-containing material that is applied to the soil to provide plant nutrition as its main function. It is processed by biological matter, animal and plant waste, and plant residue to eliminate toxic and harmful substances. It is rich in a large number of beneficial substances, including a variety of organic acid, peptides, and rich nutrient elements such as nitrogen, phosphorus, and potassium. It can provide comprehensive nutrition for crops and has a long fertilizer effect. It can increase and update soil organic matter and promote the reproduction of microorganisms. It could improve the physical and chemical properties and biological activity of the soil, which was the main nutrient for the production of green food.
Bio-organic fertilizer refers to a type of fertilizer that has both the effects of a biochemical fertilizer and an organic fertilizer. It is a compound of specific functional microorganisms and organic materials that are mainly derived from animal and plant residue (such as livestock manure, crop straws, etc.) and have been harmlessly treated and decomposed. After the beneficial microorganisms enter the soil, they form a symbiotic relationship with the microorganisms in the soil, which suppresses the growth of harmful bacteria and transforms them into beneficial bacteria. They interact and promote each other to play a cooperative role in the group. The beneficial bacteria produce a large number of metabolism products in the growth and reproduction process to promote the decomposition and transformation of organic matters. It can directly or indirectly provide various nutrients and stimulating substances for crops, promote and regulate the growth of crops, and recover agricultural waste. It can reduce environmental pollution, is safe for people, livestock and the environment, and is non-toxic. It is an environmental friendly fertilizer.
Whether it was in the northwest or other regions, the difference between organic fertilizer and bio-organic fertilizer was mainly that bio-organic fertilizer contained the essential feature of specific functional microorganisms. There were differences between the two in terms of source, mechanism of action on soil and crops, and environmental benefits.
