Correct methods for using cotton seedling protection agent
I. Methods for using cotton seedling protection agent The cotton seedling protection agent consists of three bags: large, medium and small. The specific seed soaking steps are: 1. Soak 5 kg of cotton seeds in clear water mixed with three parts hot (about 70°C) and one part cold for 5 minutes, remove the cotton seeds and squeeze out excess water. 2. Dissolve the small bag of reagent in 0.5 kg of clear water, pour it into the cotton seeds soaked in the three-hot-one-cold clear water, stirring while pouring, and after thorough stirring leave for 24 hours (stirring 2~3 times during this period). 3. Dissolve the medium bag of reagent in 1.54 kg of clear water, pour it into the cotton seeds soaked with the small bag of reagent

Key Technical Points for the Use of Different Chemical Control Agents on Cotton
Chemical control of cotton means using chemical regulation methods to shape cotton into an ideal plant type and create a high-photosynthetic-efficiency population. In this way, plants can grow vigorously, pest and disease occurrence can be reduced, cotton yield can be increased, and quality can also be improved. However, there are currently many chemical control agents, and correct application techniques should be adopted according to different agents to achieve better results. 1. Mepiquat chloride. At present, mepiquat chloride is widely used in cotton chemical control, and its effect is also relatively ideal. It can reduce cotton plant height, decrease the number of fruiting branches, promote the shift of photosynthesis toward reproductive growth, reduce cotton boll

Tea seed cake can be used as a pond-clearing agent
Pond clearing and disinfection generally use quicklime or bleaching powder, but if the pond is used for shrimp farming, using tea seed cake to clear the pond has effects that other agents cannot replace, with better results. Tea seed cake, also called tea seed meal, is a purplish-brown granular residue left after oil is pressed from the fruit of plants in the Theaceae family. Tea seed cake contains saponin, also called saponin glycoside, which is a hemolytic toxin that can dissolve the red blood cells of fish, so it can kill various wild and trash fish such as loach, as well as snails, river mussels, frog eggs, tadpoles and some aquatic insects. Saponin is easily
