    Chlorpyrifos, as an organophosphorus insecticide and acaricide, is suitable for the control of various chewing and sucking mouthparts pests such as wheat. However, excessive use will lead to changes in crop soluble proteins, glutathione-S-transferase, glutathione peroxidase, etc., resulting in pesticide stress, thereby affecting crop growth. In 2015, Zhang Shoudong, Northwest Institute of Plateau Biology, Chinese Academy of Sciences, etc. published an article "Effects of Alginate Oligosaccharides on Physiological and Biochemical Indexes of Wheat Seedlings Under Chlorpyrifos Stress". In this experiment, spraying 0.4% concentration of Alginate oligosaccharides significantly alleviated the decrease of chlorophyll content and wheat biomass in wheat seedlings under chlorpyrifos stress, inhibited the increase of proline, soluble protein and soluble sugar content, and enhanced wheat Resistance to chlorpyrifos stress. Test Results: (Note: CK: distilled water treatment, T0-T4:...

Rhizobium soybean is a live microbial preparation. The rhizobia in the root nodules and the legumes are mutually beneficial: the organic matter produced by the legumes through photosynthesis is partly supplied to the rhizobia; the ammonia produced by the rhizobia through biological nitrogen fixation is supplied to the legumes plant. , it fixes free nitrogen in the air to supply soybeans to meet soybean demand for nitrogen. It is a good measure to increase soybean yield, save fertilizer and reduce pollution, and has been valued by researchers around the world. First, the role of rhizobia 1. Nitrogen fixation Soybean rhizobia uses the products of soybean photosynthesis as energy, and converts nitrogen in the air into nutrients required for soybean growth and development. Rhizobium and soybean have a symbiotic nitrogen fixation relationship. At the beginning, soybean rhizobia fixed little nitrogen, until flowering to drum. The initial stage of grain is the peak of nitrogen fixation by so...

  γ-aminobutyric acid (CAS number: 56-12-2), (GABA for short), with a relative molecular weight of 103.1, is a four-carbon, non-protein amino acid, which is widely used in vertebrates, plants and Widespread in microorganisms. The content of GABA in plant tissues is extremely low, usually between 0.3 and 32.5 μmol/g.  It has been reported in the literature that the enrichment of GABA in plants is related to the stress response experienced by the plant. When subjected to stress such as hypoxia, heat shock, cold shock, mechanical damage, and salt stress, it will lead to the rapid accumulation of GABA.  It has become a research hotspot to process plant food raw materials into GABA-rich functional products after a certain stress treatment or through microbial fermentation to increase the GABA content in the body.  As a novel functional factor, GABA has been widely used in the food industry.  Foods developed using raw materials such as GABA-rich  germinated brow...

Potassium indolylbutyric acid (IBA-K) is the potassium salt of indole butyric acid with relatively stable properties. It is mainly used to promote the development of capillary roots. It can be used as basal application, flushing application, and can also be added with compound fertilizer, compound fertilizer, BB fertilizer, etc. For use, such as seedling cuttings, it is recommended to use it in combination with sodium naphthalene acetate. Potassium indole butyrate is a root-promoting plant growth regulator, which induces crops to form adventitious roots. It is transmitted from leaf seeds and other parts to the plant body through foliar spraying, dipping roots, etc., and is concentrated at the growing point to promote Cell division induces the formation of adventitious roots, which are characterized by many roots, straight roots, thick roots, and many root hairs. It is easily soluble in water, has higher activity than indole acetic acid, decomposes slowly under strong light, and has st...

Uniconazole is a triazole plant growth regulator widely used in cotton production. In recent years, it has an obvious effect on controlling the growth of cotton, promoting flowers and peaches, and can also increase the ratio of cotton double bolls. Welcomed by some cotton farmers.  Today, I will introduce to you a new type of plant growth regualtor, which is more effective than Uniconazole. It is better than Uniconazole because it is not prone to premature aging and defertilization of cotton. 1.

Recently, many vegetable farmers have reported that the quality of tomato sepals are poor and turned brown, so that the fruit does not look bright, which affects the sales price, and many vegetable farmers have no remedy for this. There are four main reasons for the poor quality of tomato sepals. Vegetable farmers can take preventive measures. 1. Root injury is growing poorly Due to drought, waterlogging, excessive fertilization, etc., the roots are damaged, the plant growth is poor, and the plant's endogenous hormone synthesis is insufficient, which will cause the leaves to yellow and the sepals of the fruit will age and turn yellow-brown. This requires strengthening management, improving growth, and avoiding root-damaging factors. Suggest Irrigation with rooting agents to promote root recovery, foliar spray with 6000 times of sodium nitrophenolate and 1500 times of brassinolide plus 400 times of nucleotides to promote the green synthesis of tomato leaves and sepals. 2. High tempe...

 Soil compaction refers to the lack of organic matter and poor structure on the surface of the soil. The structure is destroyed and the soil is dispersed due to external factors such as irrigation or rainfall. After drying, the soil becomes hardened by cohesive force. The main reasons for the formation of soil citrus are as follows: 1. The acidity of the soil is too large or too small, such as acid rain. 2. Plastic products, such as plastic mulch, have not been cleaned up in time and cannot be completely decomposed in the soil. 3. Long-term single application of chemical fertilizers will not be able to be replenished in time for humus, which will also cause soil compaction and may also crack. (1) After excessive application of nitrogen fertilizer to the soil, the nitrogen supply of microorganisms will increase by 1 part, and the corresponding carbon consumption will increase by 25 parts. The consumed carbon comes from soil organic matter, and the low organic matter content affects ...
