The hotter the radish is, the better the anti-cancer performance is.
The double-bond ribonucleic acid of interferon inducer in white radish is highly resistant to oral enzymes. It is not easy to degrade in swallowing and has no side effects. In recent years, some domestic medical scientists have found that the interferon inducer contained in white radish was injected into mice and found that the malignant tumor in the body was reduced by 50% to 60%.

Don't forget to protect the parent fish in order to induce labor.
Reducing the death of spawning parent fish is an important technical work for fish fry producers. In the production practice, we found that there are two reasons for the death of parent fish: first, the physical exertion of parent fish in the process of spawning and reproduction, coupled with the side effects of spawning drugs, reduce the resistance of parent fish, if the fish is seriously injured, a variety of pathogens will take advantage of the opportunity to infect the fish and cause disease, resulting in the death of the parent fish. Second, the physique of the parent fish is poor, the gonadal development is poor, or the water temperature changes greatly during the induction of labor, and the dosage of drugs used to induce labor is inappropriate.

Schisandra chinensis can reverse the multidrug resistance of tumor.
The crude extract of Schisandra chinensis and its active component Schisandrin A can reverse multidrug resistance and greatly improve the sensitivity of tumor cells to antineoplastic drugs. The structure of Schisandrin An is different from the known multidrug resistance reversal agents, so it is a kind of Chinese herbal medicine with development prospect. This is a "new discovery" disclosed in his academic report by Liu Gengtao, a researcher at the Institute of Medicine of the Chinese Academy of Medical Sciences and academician of the Chinese Academy of Engineering, at the recent Guangzhou Pharmaceutical 2006 Cross-Strait Pharmacy (Yangcheng) Forum.

Three inducing factors of Red Leaf Stem Blight in Cotton
Cotton red leaf stem blight is a physiological disease caused by potassium deficiency, which occurs in the middle and later stages of cotton growth, especially in dry years. The disease of cotton in the field generally begins to show in the bud stage, and the disease is the most serious in the boll opening stage. The symptoms were mainly on the leaves, and the diseased leaves developed from the top to the bottom and from the outside to the inside. The diseased leaves began to lose green from the edge, first yellow, then red spots, and finally the whole leaf turned red, the mesophyll thickened, wrinkled and brittle, and the veins remained green. When the disease is serious, the leaves of the whole plant turn red and brown after losing green, and the leaves scorch and fall off into smooth rods.

The cause and Prevention of the formation of Soybean pods without fruiting
First, the reasons for the unfruitful pods. 1. Improper selection of varieties or planting system. Generally speaking, the late-maturing varieties with poor resistance induce the formation of pods due to the low temperature during filling, which seriously affects the filling speed. The content of boron in soil nutrients decreased sharply due to the continuous cropping of soybean. Because boron is an important trace element to promote the formation and growth of soybean pods, its lack of soybean pods leads to the failure of soybean pods. At the same time, continuous cropping of soybean will aggravate the harm of soybean diseases and insect pests, thus inducing pods to be unfruitful.

Application of Plant growth regulators in Flower planting
Growth regulators can control the synthesis or metabolism of hormones in flowers and plants, change the distribution of assimilates, regulate the growth and development of flowers, and their effects can make flower stems thick and short, leaves dark green and leaves thicker. Due to the inhibition of stem growth, the competition for nutrients during flower bud germination is reduced.

Application of Interferon in the treatment of Infectious Canine Hepatitis
Infectious canine hepatitis is an acute septic infectious disease caused by adenovirus. It was characterized by necrosis in the center of hepatic lobule, intranuclear inclusion bodies in hepatic parenchyma cells and cortical cells, and prolonged bleeding time. Infectious canine hepatitis does serious harm to dogs and causes great economic losses to the dog industry. The virus has strong resistance and can survive in the soil for a long time under the condition of low temperature. it still has pathogenicity after 10 to 14 days, and can survive in the dog nest for a long time. Sick dogs and recovered dogs with virus are the source of infection of the disease, and their blood secretions and excretions

Pathogen characteristics of aflatoxin in duck
(1) aflatoxin production aflatoxin, like other mycotoxins, is one of the metabolites of toxin-producing fungi in the process of growth and reproduction in the substrate. This toxin was found in the etiology of "turkey X disease" in England in 1960. In the second year, it was found that the peanut cake contaminated with Aspergillus flavus could induce liver cancer in rats and confirmed that aflatoxin was a carcinogenic mycotoxin. The main fungi producing aflatoxins are Aspergillus flavus and parasitic Aspergillus flavus, while Aspergillus winterii and Aspergillus winterii

(1) A wide range of sources of infection. 1. The source of infection in the process of sericulture: dead silkworm, pupa, moth and their diseased silkworm feces, silkworm sand, old silkworm and rotten cocoon are serious sources of infection of sericulture. 2. Cross-infection with wild insects, mulberry leaves contaminated by diseased field insects, insect carcasses and insect droppings are another source of infection of silkworm disease. 3. Pathogen accumulation and poison pollution in sericulture environment. (2) due to poor feeding and management, silkworms are physically weak and prone to disease. Do not attach importance to
