  • Application Technology of EM Bacteria in High-Quality Rice Production

    In recent years, China's grain output has been greatly increased, but it also faces the contradiction of severe environmental pollution and low quality of agricultural products. Long-term unreasonable application of chemical fertilizers has become one of the important factors that waste resources, pollute the environment, increase production costs, and affect the quality of agricultural products. With the improvement of human environmental protection and health awareness, the demand for pollution-free food is also increasing day by day. Therefore, in agricultural production, it is imperative to develop new biological organic fertilizers to reduce or even eliminate chemical fertilizers and produce high-yield, high-quality, and efficient agricultural products. EM

  • Scientific Potassium Application for High Yield and Quality in Garlic

    Potassium is an essential nutrient for crop growth, and its role in increasing crop yields and improving the quality of agricultural products has been confirmed in many crops, but there are still few reports on the effect of potassium on garlic yield and quality. Through two years of field trials, the Soil and Fertilizer Institute of the Zhejiang Academy of Agricultural Sciences proved that potassium application to garlic achieves high yield and quality. 1. The role of potassium application in garlic. The results of two years of field trials showed that potassium fertilizer application to garlic had an obvious yield-increasing effect. Under equal nitrogen and phosphorus levels, applying potassium fertilizer compared with no potassium fertilizer increased yield by 60.0

  • B-Mode Ultrasound Diagnostic Methods and Applications in Canine Pregnancy

    The application of ultrasound diagnostic technology in the veterinary field began in the mid-1960s, initially using A-mode and D-mode ultrasound. With the development of electronic technology and the electronics industry, it advanced to M-mode and B-mode by the mid-1970s. The B-mode ultrasound diagnostic apparatus, also known as B-ultrasound, uses brightness modulation, reflecting signal intensity through the brightness or darkness of light spots. Because B-ultrasound can perform real-time imaging of the body, display two-dimensional images of the examined area, and clearly show the dynamic changes, morphology and adjacent relationships of internal organs and tissues, as well as the internal echoes and structures of soft tissues, the distribution of blood vessels and other ducts, B-ultrasound is also called a real-time ultrasonic tomographic imaging diagnostic apparatus. Furthermore, because B-ultrasound causes no damage to the body, allows treatment of the examined area under its guidance, and has a wide range of applications, it gained the attention and widespread use of the medical community as soon as it was introduced, and has now become one of the four major medical imaging diagnostic methods. In veterinary and livestock production, B-ultrasound has likewise been widely applied; at present, whether abroad or domestically, whether in basic veterinary theoretical research, livestock production practice, or clinical veterinary application, B-ultrasound plays a very important role, and has been hailed as a revolutionary change in veterinary diagnostic technology, being applied in fields such as pregnancy monitoring, superovulation, disease diagnosis, and selective breeding and fattening monitoring. At present, one of the main uses of B-ultrasound is monitoring the uterus and fetus during animal pregnancy. Combining the author's experience, this article briefly describes the main applications of B-ultrasound in canine pregnancy monitoring.

  • Rational Application Methods and Key Points for Using Allicin

    Although allicin has very good effects, it must still be used rationally, and the dosage must not be blindly increased, so as to avoid waste or even adverse effects. Huang Xingguo et al. conducted a preliminary study on the application effect of allicin in rice field eel farming, and the results found that due to different doses of allicin added at different feeding stages, the survival rate and disease prevention and control effects differed: in the feeding stage without added allicin, after 1 month of feeding, the survival rate was 89%, and the main causes of death were red-skin disease and enteritis; when 200mg/kg and 40

  • Detailed Explanation of the Application Methods of Tea Seed Cake in Aquaculture

    Tea seed cake contains tea saponin with hemolytic action, 11%-16% crude protein, 5%-7% fat, 40% digestible sugar, 11% nitrogen, 0.37% phosphoric acid, 1.23% potassium, and various amino acids essential for animals and other nutrients, and it has a wide range of applications in aquaculture. ① Pond treatment and water fertilization. Tea seed cake is the preferred pond-clearing agent for ponds with mixed culture of fish, shrimp and crabs. The pond treatment method is: in a pond with a water depth of 30-50cm, use 25kg/hm3 of crushed tea seed cake; for a pond with a water depth of 1m, it can be increased to 50k

  • The function and application method of the automatic mounting-cluster agent for ripe silkworms

    (1) Brief introduction "Automatic mounting-cluster agent for ripe silkworms" is a new type of silkworm medicine that promotes uniform maturity of silkworms and automatic mounting of ripe silkworms onto clusters; at the same time, unripe silkworms, diseased silkworms and weak silkworms do not climb onto the clusters, improving cocoon quality and reducing the rate of inferior cocoons. (2) Advanced nature of the technology "Automatic mounting-cluster agent for ripe silkworms" passed appraisal organized by the Guangdong Provincial Higher Education Bureau in 1993, and experts unanimously considered that the result reached the domestic leading level. In China, molting hormone is used to make silkworms mature uniformly; when they are ripe, they are picked up one by one by hand and placed on clusters, or unripe and ripe silkworms are picked up together with both hands and placed on clusters.

  • A Detailed Guide to the Application of Fresh-keeping Technology for Exported Garlic

    Garlic is one of the main varieties of agricultural products exported from China, with an annual export volume of about 300,000 tonnes. Of this, refrigerated (fresh-keeping) garlic accounts for about 60% of total exports. Therefore, whether the fresh-keeping technology is mature has a direct impact on the quality of exported fresh-keeping garlic. I. The fresh-keeping principle of garlic. After the cloves of a garlic bulb develop and mature, the bulb immediately enters a dormancy period of 1-2 months, during which it will not sprout even under suitable environmental conditions such as temperature, humidity and gas composition. After the dormancy period, the bud sheath and bud primordium begin to grow and become active, and under suitable conditions the young sprouts gradually germinate. In practice, the storage and fresh-keeping of garlic means that after the dormancy period of the bulb, necessary measures are taken to create unsuitable growing conditions and thereby force it to remain dormant. That is, through appropriate low-temperature, low-oxygen and other measures, its intensity of life activity is inhibited, the rate of consumption of its substances is reduced, and its original fresh state is maintained.

  • Detailed Explanation of the Production and Application Technology of Shiitake Mushroom Capsule Spawn

    At the end of the last century, Japan invented capsule spawn and applied it on a large scale to log-cultivated shiitake mushrooms. In 1999, this technology was introduced to our country. After years of research, the Qingyuan County Edible Fungi Research Center overcame the technical difficulties of applying capsule spawn to substitute-material-cultivated shiitake mushrooms and achieved domestic production. Because capsule spawn has the advantages of saving labor, saving effort and a high survival rate, it is very suitable for large-scale production. In the past two years, the amount used has doubled and redoubled, and tens of millions of bags have been promoted and applied so far. It is estimated that in a few years this technology will become common in our country.

  • Application of Euonymus japonicus 'Aureo-marginatus' in garden color blocks

    Garden construction cannot do without the use of color. At present, red, yellow and green shrubs are commonly used in garden construction to form color blocks, so as to enrich the color composition of the garden. Because plants in red and yellow are relatively few, currently red small shrubs are mostly Loropetalum chinense var. rubrum, yellow small shrubs are mostly Ligustrum vicaryi, while green small shrubs have relatively rich varieties, including Euonymus japonicus 'Microphyllus' and Ilex crenata 'Convexa'. The commonly used Ligustrum vicaryi among yellow small shrubs has its obvious shortcomings: Ligustrum vicaryi is a deciduous shrub of the genus Ligustrum in the family Oleaceae, light-loving, slightly shade-tolerant, not tolerant of drought
