Principles and Methods of Oral Medication for Preventing Rice Field Eel Diseases
Also called the oral administration method, it generally involves mixing the medication to be used into the feed at the prescribed dose to make medicated bait, so that the rice field eel ingests the medication by eating the feed, thereby achieving the purpose of preventing and treating diseases. The problem with using this method is that usually once rice field eels become ill, it becomes a group outbreak, with generally reduced appetite or almost complete cessation of feeding, meaning that the amount of medication entering the rice field eels' bodies will not be very large, and the treatment effect will not be very good either. Therefore, certain technical measures need to be taken to do everything possible to get the sick rice field eels to better ingest the medicated bait, such as stopping feed

Detailed method for making glutinous rice paper from sweet potato
Starch film, commonly known as glutinous rice paper, is an edible film made from starch as a raw material. In the food industry, it is used as a laminated packaging material for candy and pastry foods. The process for making glutinous rice paper: starch emulsification, sieving -- batter preparation (adding phospholipid emulsion) -- steam insulation -- film casting -- finished product 1. Starch emulsification and sieving: Screen sweet potato starch through a 100-mesh sieve, add water at 50-55 degrees Celsius to emulsify it. The amount of water used is 2.5-3 times that of the starch. After preparation, the concentration is 15-17 Baume. Stir continuously so that the starch is completely and evenly dispersed in the water. Then pass it through a 100-mesh copper sieve and pump it into the gelatinization pot.

How to prevent rice field eel diseases in spring? Garlic and salt solution works well
After overwintering, rice field eels begin to become active in spring when the temperature rises. At this time, they are very susceptible to saprolegniasis, skin rot disease, bacterial septicemia and other diseases, which can lead to death. If a clarified solution made by soaking fresh garlic and high-quality salt at an 80-100 fold dilution is promptly splashed into the breeding pond, once every 3-5 days, for 2-3 consecutive applications, splashing 2-3 kg per square meter of breeding pond each time, evenly sprinkled on the water surface, the rice field eels will not be infected by the above diseases, and the breeding survival rate will be high.

How to Add Value to Sweet Potato and Rice Through Processing
Sweet Potato Starch Production Technology Wash the sweet potatoes, drain the water, crush them into pieces about 2 cm in size with a crusher, feed them into a stone mill or electric pulp grinder, add 3 to 3.5 times their volume of water, and grind into a starch slurry. Pour the starch slurry into a sieve with a mesh size of 60 and sieve out the potato residue to obtain starch milk. Place the starch milk in a settling tank and let it stand overnight so that the starch settles to the bottom of the tank. Drain off the supernatant, take out the crude starch, repeatedly rinse and settle it with clean water to obtain pure starch, then sun-dry, crush and sieve the starch to obtain

Shallow water warming for rice to promote tillering, fertilization with "two preventions" to grow strong seedlings
Due to the impact of unfavorable weather conditions such as low temperatures, frequent rain and insufficient sunlight, rice has been slow to turn green, with yellow leaves, few tillers and delayed growth. For this reason, rice expert Xu Yirong, after an on-site inspection in the Heilongjiang reclamation area, proposed countermeasures such as shallow water warming to promote tillering, fertilization with "two preventions" to grow strong seedlings, and fitness-based disease prevention. First, water layer management must be done well: deep water is a heat-preservation measure, shallow water is a warming measure, and not establishing a water layer is a cooling measure. For plots with deep water formed by rainfall, drainage must be carried out promptly to raise temperature, promote root growth and promote

What are the key points of glutinous rice cultivation techniques? A detailed explanation
(1) Select good varieties: Choose high-yield, high-quality glutinous rice varieties with a suitable maturity period, strong glutinousness, excellent grain quality, and suitability for producing peach slices. The main recommended varieties include "Jinling Xiangnuo", "Yinqiao Nuo", "Hexiang Nuo", "Myanmar Nuo", and others. (2) Sparse sowing under plastic film to grow strong seedlings: Seeds must be disinfected before sprouting. In areas below 300 m altitude, sow from March 5-10; at 300-400
