1. Concentrated multivalent inactivated vaccine against Streptococcus suis: Action: prevents septicemia, encephalitis, polyarthritis and abscess disease caused by Streptococcus suis. Usage: boars and sows are injected twice a year, 3 ml per head by intramuscular injection each time; pigs over one month of age are injected 2-3 ml per head intramuscularly each time. 2. Inactivated bivalent vaccine against infectious atrophic rhinitis of swine - toxigenic Pasteurella multocida: Action: prevents atrophic rhinitis and pasteurellosis in pigs. Usage: sows are injected intramuscularly in the neck 1 month before farrowing

Application Methods of Lime in Edible Mushroom Production
Lime has a significant disinfection and sterilization effect and is also rich in calcium, giving it a wide range of uses in edible mushroom production. 1. Application on the site: Clear the weeds around the site, spread a layer of lime powder, then clean the cultivation room thoroughly, spray conventional insecticide, and spread another layer of lime powder. This can kill some contaminating microorganisms and reduce the contamination baseline, especially bacterial contamination, and can also prevent pests such as slugs from invading the site and causing damage. 2. Application in the substrate: Most edible mushrooms can grow normally in a slightly alkaline

Key Technical Points and Application Methods of Wheat Straw and Wheat Chaff Mulching
Wheat straw and wheat chaff mulching involves evenly spreading wheat straw or wheat chaff around autumn crops or between rows to form a certain mulch layer, with an appropriate amount of soil pressed onto it in spots, so as to mulch and preserve soil moisture. For wheat straw and wheat chaff mulching, it is necessary to grasp the timing and mulching amount well, and to apply chemical fertilizers reasonably and according to other such principles. 1. Timing. The relatively suitable mulching time is from late June to early to mid-July. Too early makes it easy to press down the seedlings, while too late means the crop plants are tall and difficult to work with. After mulching, if there is no rain or insufficient rainfall, it will affect the rotting and decomposition of the straw, and the effect will be poor, so watering should be done in time. It can also be done at

Processing, Application Methods and Techniques for Tea Seed Shells
Oil tea is a woody oil crop unique to China. According to statistics, China currently has more than 3.47 million hectares of oil tea area, with an annual output of 56.6 billion kg of oil tea seeds. Tea seed shells contain 52.15% lignin, 30.27% pentosan, 5.43% saponin, 2.47% tannin, 0.43% water, 0.13% oil, and 9.12% other components. Because tea seed shells are high in lignin and pentosan, research on their utilization is currently focused on the preparation of furfural, activated carbon and xylitol. 1. Tea seeds

Planting Performance and Application Prospects of Different Simplified Rice Cultivation Methods
1 Planting performance of several simplified rice cultivation methods 1.1.1 Actual harvested yield. The actual harvested yield was highest for machine-transplanted rice, with an average yield of 9000 kg/hm2; followed by hand-transplanted rice, with an average yield of 8850 kg/hm2; third was seedling-throwing rice, with an average yield of 8700 kg/hm2; fourth was wheat-intercropped rice, with a yield of 8400 kg/hm2; direct-seeded rice had the lowest yield, averaging 8250 kg/hm2. 1.1.2 Number of panicles per unit.

Engineering Applications and Management Methods for Hokkaido Boxwood
Hokkaido boxwood is an excellent landscaping material, but because it was introduced and promoted relatively late, many design units are still not familiar enough with its growth habits and characteristics, and it is used sparingly or configured inaccurately in design applications. As a result, nursery growers feel lost about how to cultivate and prune it: they plant a whole field of seedlings but do not know how to manage them, and after several years pass, they are left sighing in dismay! Based on several years of research and practice at this nursery, the following cultivation trial methods are considered effective. 1. Single-trunk small tree. When the seedling grows to 1.8-2 m, pinch out the growing tip at the top, keep the upper 30 cm for branching, and remove all branches below so that it concentrates on developing the upper part into a crown.

A detailed guide to the application technology of phenthoate: master the correct method of use
50% Miechonglu emulsifiable concentrate (phenthoate) is an organophosphorus insecticide with moderate toxicity (only 1/30 that of methamidophos). It also has stomach-poison and contact-killing effects, and gives good control of various pests on many crops such as rice, cotton, vegetables and fruit trees. It is especially outstanding against rice stem borers, and no pest has yet developed resistance to it. The application technology of this insecticide is described below: 1. Use technology: 1. To control rice striped stem borer and rice yellow stem borer, use 50% Miechonglin emulsifiable concentrate per mu

Application Methods of Phytase in Pig and Poultry Diets
Phytic acid or phytate is commonly present in plant feedstuffs, and most of the phosphorus in them exists in the form of phytate phosphorus. Phytic acid can form stable complexes called phytates with metal ions such as calcium, iron, zinc, and copper ions, and can also bind with proteins and starch, reducing the activity of endogenous amylase, protease, and lipase, and significantly lowering the digestibility of various nutrients. Phytic acid is not absorbed by monogastric animals and is mostly excreted in feces, which not only greatly reduces phosphorus utilization but also causes environmental pollution, especially water pollution.
