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.

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

What are the precautions for releasing brood shrimp in rice-shrimp rotation
Currently it is the golden time for releasing brood shrimp. When releasing brood shrimp, farmers should pay attention to the following points: 1. Do a good job of basic rice field renovation, mainly by digging the surrounding ditches well, reinforcing the embankments, building the inlet and drainage systems well, and setting up anti-escape facilities. 2. Do a good job of disinfecting the surrounding ditches, preferably by spreading quicklime evenly, with a dosage of 100 jin per mu, and release the brood shrimp one week later. 3. Select good brood shrimp and release them reasonably. The brood shrimp to be released should be sexually mature, healthy, and have complete appendages, and should be released at a female-to-male ratio of 3:1. Release brood shrimp per mu

Key Points of High-Yield Cultivation Techniques for Upland Rice Gaoshan No. 1
Upland rice Gaoshan No. 1 was bred from a wild upland rice that grows in the Dupangling area on the border of Hunan and Guangxi. Because this wild upland rice has long grown under harsh natural environmental conditions, it has strong resistance to pests, diseases and weeds, and is also tolerant of poor soil and drought, with a particularly well-developed root system. The Gaoshan No. 1 variety is suitable for both paddy and upland cultivation. In 2000, it was trial-planted in Tancheng County, Shandong Province and Wencheng County, Zhejiang Province, with the highest yield reaching 9750 kg/hectare and an average yield of 7687.5 kg/hectare, an increase over local hybrid rice

Breeding and High-Yield Cultivation Techniques of the Rice Variety Lindao 12
1 Breeding history: In 1999, the Linyi City Rice Research Institute used radiation mutation breeding, treating 500 g of Yujing 6 seeds with 60Co alpha-rays at a dose of 40,000 roentgens, and planted the Mo generation that year; the population showed high sterility, and all seeds (M1 generation) were harvested in autumn; in the winter of the same year, winter multiplication in the south was carried out to add a generation, planting the M1 generation, and the population showed high segregation, and all M2 generation seeds were harvested. In 2000, the quartering bulk breeding method was used, planting the M2 generation, and in autumn superior plants were selected from the mutant population.

Detailed Explanation of Key Techniques for Super-High-Yield Cultivation of Double-Season Rice in South China
(1) Sow at the right time and cultivate strong seedlings. For early rice, use dry-raised seedlings, with a seeding rate generally of 90 g/m2 and a sowing period in mid-to-late March; for late rice, use sparse sowing for strong seedlings or two-stage seedling raising, with a seed rate of about 1.0 kg per mu. (2) Ridge and bed cultivation. Bed width 3-4 m, ditch width 0.2-0.25 m, and open surrounding ditches well to facilitate water management and field operation management. (3) Wide-row close planting. The planting density is 30-40 hills/sq m, with a row spacing of about 25 cm. Generally, early rice has 3-4 seedlings per hill, and late rice is transplanted as single seedlings or double seedlings, ensuring
