Detailed Explanation of the Characteristics and Cultivation Techniques of the Glutinous Rice Variety Xianghu 25
Xianghu 25 is a medium-maturing late glutinous rice variety bred by the Jiaxing Academy of Agricultural Sciences in Zhejiang Province through composite hybridization of Aigeng 23 / Xianghu 14 ∥ Ce 21 / Aigeng 23. As a single-crop rice, its plant height is about 100 cm. As a second-crop rice, its plant height is 80-85 cm. When grown as single-crop late rice in the suburban counties of Shanghai, it is generally sown in late May, transplanted in late June, and matures in late October. As a second-crop rice, it is sown before June 20 and matures at the end of October to the beginning of November. It is resistant to rice blast and relatively resistant to bacterial leaf blight. The incidence of sheath blight is also lighter than that of the control. The brown rice recovery rate is about 82%, the rice grains have little white belly, and the color

Brief Introduction to the Characteristics and Traits of the New Glutinous Rice Variety Ningnuo 2
The Ningnuo 2 variety was approved and named at the seventh meeting of the Ningxia Variety Approval Committee. It has the characteristics of high yield and good quality, with a yield of 650 kg per mu and over 750 kg in high-yield fields. In 1987, it participated in the regional trial of glutinous rice and increased yield by 13.9% compared with Ningnuo 1. The breeding of Ningnuo 2 was a successful attempt in the history of high photosynthetic efficiency breeding in China, setting a new record for high yield of glutinous rice in Ningxia. This variety grows neatly and cleanly as a population, has a long leaf functional period, and fast grain filling. It heads in early August and matures in late September, with a growth period of 14

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

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
