Variety Registration Number: GS-02-001-2008
Parents Source: Modified diploid red fleas Improved tetraploid 鲫鲤♂
Breeding Unit: Hunan Normal University
A brief introduction of the variety: Xiangyunjing 2 is a combination of distant hybridization techniques and gynogenetic development techniques. It uses the improved diploid erythrozoa as female parent, and is obtained through multi-generation breeding and breeding. This, a triploid new variety obtained through interspecific hybridization.
The species is triploid (3n=150) and has the characteristics of rapid growth and infertility similar to that of Xiangyun Yun. It has a high body size and fresh tender meat. The amount of semen of the paternal parent is 1.6 times higher than the parental semen volume of Xiangyunjing. 3 times, greatly reducing the cost of seed production.
In 2008, it was approved by the National Aquatic Products Breeding and Approving Committee, and it is suitable to be cultivated in freshwater that can be manually controlled throughout the country.
Breeding technology points: In addition to reference to the four home fish artificial breeding technology, but also need to pay attention to the following points:
1. Strictly sterilize clear ponds and thoroughly remove enemy and wild fish;
2, proper stocking density;
3, appropriate fertilizer underwater pool, scientific feeding.
Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
