Methods and Technical Key Points for Controlling the Two Migratory Rice Pests
Control recommendation: For single-cropping rice, carry out one comprehensive control treatment from July 13-15, targeting mainly the rice leaf roller and the white-backed planthopper, and also controlling the small brown planthopper and rice thrips. Pesticide formulations: 1. Use 40-50 ml of 5% fipronil (Regent) suspension concentrate per mu; 2. Use 70-80 ml of 31% fipronil-triazophos (Sanfu) per mu; 3. Use 100 ml of 50% phenthoate per mu; 4. Use 50 ml of 40% chlorpyrifos (Xinnongbao, Saiben) per mu plus 2 g of 80% fipronil (Regent) water-dispersible granules; 5. Use 3

Detailed Explanation of Key Technical Points in the Quick-Freezing Process for Exported Shrimp Meat
1. Process flow: Raw material acceptance → Raw material storage → Raw material thawing → Shrimp peeling → Acceptance → Washing → Soaking → Blanching → Cooling → Size grading → Freezing → Ice glazing → Metal detection → Boxing → Refrigerated transport 2. Operational key points 2.1 Raw material acceptance QC (quality control team) must inspect quality to prevent blackened shrimp. If blackened shrimp are found, promptly report back to the importer for handling. Keep a "Raw Material Acceptance Record" for each batch of raw materials. 2.2 Raw material storage: Store by container batch number at

How to manage fish fingerlings in autumn? These technical points must be mastered
(1) Pond clearing. After the beginning of autumn, the fingerlings should be transferred to a pond that has been cleared and disinfected for cultivation, so that the fingerlings can safely overwinter. Where there are difficulties in the turnover of water sources and fish ponds, all the fingerlings can be transferred out for temporary holding, and the original pond can be disinfected with 75-100 kg of quicklime per mu, the water quality can be fertilized according to conventional methods, and the fingerlings can be transferred back after the drug has dissipated. (2) Separate rearing. The specifications of the fingerlings stocked in the same pond must be consistent. Large-sized fingerlings have a large food intake and a strong ability to compete for food. If small-sized fingerlings are stocked at the same time, the small-sized fingerlings will

Full Analysis of the Key Technical Points for Lotus-Rice-Fish Integrated Farming
"Lotus-rice-fish" integrated farming refers to a co-culture model in which both rice is planted and fish are raised during the growing period of lotus root. The relevant integrated farming techniques are briefly introduced below. 1. Reasonable site selection. Choose gray mud fields with sufficient water sources, strong water retention capacity, and medium or above fertility. Fields with water-quality concerns, cold-waterlogged fields, and perennial lotus fields are not suitable for selection. 2. Select improved varieties. For lotus seeds, choose excellent varieties with large grains, a long flowering period, and high yield; for rice, it is advisable to choose early-maturing or early-to-medium-maturing varieties, such as Minke Zao No. 8, Zhefu 218, etc.; for fish, mainly stock common carp.

Detailed Explanation of Key Technical Points for Scientific Application of Fishery Drugs
Fishery drugs are all substances used to prevent, control and treat diseases, pests and harm of aquatic animals and plants, promote healthy growth of cultured species, enhance the body's disease resistance and improve the quality of aquaculture water. Here we specifically introduce several correct medication methods for the prevention and treatment of aquatic animal diseases: 1. Apply drugs according to the disease. There are many varieties of fishery drugs, and their physical and chemical properties differ. Therefore, before using fishery drugs, the main diseases and pathogens of the cultured prevention and treatment targets must first be accurately diagnosed, a treatment plan must be made, and then a suitable drug variety must be selected for targeted treatment; otherwise, it will not only fail

Key Technical Points and Detailed Explanation of Epidemic Prevention Methods for Swine Disease Immunization
Reference Immunization Program 1. Vaccines Recommended for General Inoculation 1.1 Classical Swine Fever Immunization: Newborn piglets receive their first vaccination with the conventional dose of lapinized attenuated classical swine fever virus vaccine at 20 days of age. (It is best to promote zero-time pre-immunization.) Piglets at 50-60 days of age receive the routine second immunization. Selected replacement pigs receive a third immunization before participating in mating. 1.2 Swine Paratyphoid Immunization: The entire herd of adult and replacement pigs are immunized at conventional doses in March of spring and September of autumn.

What are the key technical points of pig health inspection?
At present, pig production in China is still dominated by smallholder backyard farming. However, because most pig raisers lack scientific pig-farming knowledge and concepts, the level of technology in production and management - including pig breeds, feed formulation, feeding management and disease prevention and control - is very low. Pig production has long suffered from problems such as slow weight gain, low feed conversion efficiency, low profitability and even losses. Keepers and veterinary technicians should patrol and observe the health of the herd every day and deal with any problem promptly. To properly check whether a pig herd is healthy, the following technical points generally need to be mastered:

Key Technical Points for Spring Soybean Sowing in a Year of Severe Drought in Northeast China
Current drought situation in Northeast China and technical guidance for spring soybean sowing: I. Precipitation and temperature conditions last winter and this spring. In the autumn and winter of last year, the drought in Northeast China was severe, precipitation was lower than normal, and soil moisture was insufficient. From January to October 2007, the average precipitation in Heilongjiang Province was 402 mm, 20% less than the same period in previous years. In addition, this year's widespread "dry sealing of the soil" at the onset of winter was not conducive to soil moisture conservation. Since the beginning of winter, precipitation in southern Qiqihar, most of Daqing, the Hegang area, and some counties and cities in Jiamusi has been more than 90% less than the same period in previous years; other areas have had 10% to 90% less. In January 2008, the average precipitation across Heilongjiang Province was only 0.1 mm, 97% less than the same period in previous years, with most of the Songnen Plain and the western Sanjiang Plain receiving no precipitation at all for the entire month. After entering February, precipitation in various places continued to remain low. Snow depth across Heilongjiang Province also dropped significantly. Compared with the same period in previous years, snow depth in most areas of the province was about 25 cm less. In 2008, the area of cultivated land affected by drought before sowing in Heilongjiang Province may reach 50 million mu. In addition, the continuous warm winter was extremely favorable for soybean pathogens and pest eggs to survive the winter safely, and soybean diseases and insect pests may occur more heavily this year. The spring drought situation in Inner Mongolia is similar to that in western Heilongjiang Province.
