Rice gene design breeding: scientists cultivate new varieties
The aroma of rice is richer, like fruit, with higher iron and zinc content, so there is no need to supplement other nutrients; all of this can be achieved through molecular design of rice genes. Recently, the author learned from the "Crop Molecular Design and Innovation" symposium that China is currently building a large bioinformatics infrastructure platform to ensure that high-quality genes are "hit every time." Zhu Yingguo, an academician of the Chinese Academy of Engineering, said that taking rice as an example, japonica rice with a soft and glutinous texture is more favored, and people also hope that rice aroma will be richer or have special aromas such as "fruity" notes. Moreover,

Management Methods and Technical Key Points for Adult Scorpion Breeding
The Chinese scorpion (Mesobuthus martensii) generally enters the adult stage after molting 6 times. At this point, individuals that are large and robust can be selected as breeding scorpions. The period from April to September is the breeding and mating season for scorpions. Female and male scorpions can be kept together in a ratio of 3:1 and allowed to mate freely. The site for breeding scorpions should be clean and quiet, with more fresh, juicy, and nutritious food provided, and the temperature and humidity should be suitable. The density of breeding scorpions should be reduced appropriately. During the period when the female scorpion is carrying young, its nutritional requirements are greater and better than those of ordinary scorpions. Therefore, more fresh and juicy insects should be fed.

Detailed Explanation of Color Fox Breeding Technology, Mastering the Key Points of Color Fox Farming
Foxes are canids, divided into two genera. The genus Vulpes includes the silver fox (i.e. silver-black fox), red fox, and color fox; the genus Alopex includes the blue fox and colored arctic fox. Color foxes and colored arctic foxes are mutant varieties arising from coat color variation, because fox coat color variation occurs under natural conditions, and the general mutation rate is only one in one hundred thousand or one in one million. Rarity makes things precious, and a single high-quality color fox pelt sells for as much as several thousand US dollars. Foreign research and farming of color foxes has a history of over 50 years, and currently there are more than 30 color types of color foxes. In order to develop

Detailed Explanation of Key Technical Points for Velvet Deer Breeding and Reproduction
Physiological Characteristics of Velvet Deer Sexual Maturity and Suitable Age for First Mating Sexual maturity is the maturity of reproductive physiology, at which point deer can produce mature sperm and eggs and exhibit sexual behavior. The sexual maturity of velvet deer is related to factors such as breed, type, sex, genetic status, nutritional conditions and individual development. Sika deer mature earlier than red deer, females earlier than males, and deer of the same breed with good nutritional status and rapid individual development also mature earlier. General sexual maturity period: female sika deer at about 16 months of age, well-developed

What are the latest rice breeding technologies? A full analysis of the world's cutting-edge methods
Research on salt-tolerant rice breeding The aims of this research are: 1. To enable new salt-tolerant rice to adapt to cultivation in saline-alkali land. 2. To make full use of seawater irrigation when freshwater is scarce. Abroad, there have been reports of salt-tolerant crops such as tomato, melon and barley. Salt-tolerant rice bred by the University of Sussex in the UK can grow vigorously in the field, but the complexity of regulating salt content in the field must be recognized. Research on genetic engineering of salt-tolerant rice is quite active in the UK. Researchers insert genes from salt-tolerant rice into rice,

National rice gene breeding platform established with Shanghai taking the lead
According to the latest news released by the Shanghai Academy of Agricultural Sciences, a nationwide rice gene resource and molecular technology breeding platform, established with the lead of units including the Shanghai Agricultural Biological Gene Center, has achieved sharing across society, has mapped a large number of genes related to rice yield, grain quality, stress resistance and other traits, and has bred multiple new rice varieties and new combinations. According to relevant personnel from the Shanghai Academy of Agricultural Sciences, the main goals of current rice variety improvement are to further increase yield potential, improve quality and enhance stress resistance. The history of rice research shows that breakthrough

What to Pay Attention to When Buying Breeding Scorpions
1. When buying breeding scorpions, choose stock from well-known scorpion farms with a long breeding history and a relatively large scale, and check the business license issued by the industry and commerce authorities or the certificate of honor awarded by the relevant unit. Do not buy blindly just to save money or travel expenses. 2. Before buying breeding scorpions, also check the number of breeding scorpions at the supplier. If the supplier has more adult scorpions than young scorpions, it is very likely a breeding scorpion dealer. In a normal farm, the ratio of adult to young scorpions should be about 1:30. Second, also check the number of yellow mealworms at the supplier,

Questions and Answers on Building a Raccoon Dog Farm and Introducing Breeding Stock
Q: What are the prospects for raccoon dog farming? Can it make money? A: The prospects for raccoon dog farming are promising, and it can make money. Q: Which regions are suitable for developing raccoon dog farming? A: The raccoon dog's place of origin is in the northern regions of our country, and it can be raised in any area north of 30°N latitude. The quality of raccoon dog pelts produced in higher-latitude regions is superior to that of pelts from lower-latitude regions (30°--40°). To ensure pelt quality, breeding stock should be introduced from high-latitude regions (north of 40°) as much as possible, and preferably a portion of new breeding stock should be introduced every year to renew the bloodline and improve

How to Keep Neon Tetras? Detailed Guide to Care and Breeding
Also known as red neon tetra, neon light, red light fish (Hyphessobrycon innesi), originally distributed in Peru, tributaries of the Amazon River, Colombia, and Brazil. Characteristics: The neon tetra is one of the more famous ornamental fish among tropical fish. Body length 4 cm. The body is delicate and small. The whole body is covered with a cyan-green glow, with a bright blue-green band running from the head to the tail, and below the blue-green band on the rear half of the body there is also a red band, the belly is blue-white, and the red and blue bands run through the whole body, dazzling to the eye.
