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

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.

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

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

Key Technical Points for Cultivating Strong Seedlings in Rice Tray Nursing for Machine Transplanting
Economic Daily News: Raising small strong seedlings of tray-nursed machine-transplanted rice is an important part of achieving high quality and high yield in machine-transplanted rice. The specific technical points are introduced as follows: Tray soil preparation: select loam soil that is fertile, free of stubble, gravel, weeds, and free of contamination to seedlings, with a pH value of 4.5-5.5. If such acidic soil is not available, sulfuric acid or nitro humic acid can be used to adjust the acidity. To prevent damping-off and other seedling-stage diseases, apply 50-60 grams of dexon per cubic meter of tray soil. To fertilize the tray soil, add pure nitrogen, pure phosphorus,

Key Technical Points for No-Till Potato Cultivation and Management
No-till potato cultivation is a cultivation method in which, after the late rice or single-crop middle rice is harvested, the soil layer is not plowed, fertilizer is applied directly to the soil surface, potato tubers are planted, and then rice straw is spread as mulch. This method can save the labor of plowing and reduce labor intensity, and because the rice straw and potato stems and leaves are returned to the field, it plays a role in fertilizing the soil. It is a sustainable agricultural farming model that saves labor, saves effort, reduces costs, and increases income, and it is also a good approach for making full use of winter fallow fields in the limestone mountainous areas of northern Guangdong. The key technical points of its cultivation are introduced as follows: 1. Sprouting
