Green seedling fast-growing young
The European and American Yang 107 is a scientific research achievement of the Institute of Chinese Academy of Forestry. 107 Poplar trees are tall, straight, bark gray, thick bark, narrow branches with narrow crowns and fine lateral branches. Easy to breed and grow quickly. Its prominent features are fast growth, high quality, vegetative reproduction and greater economic benefits; the average annual growth of breast diameter is 3.5-4 cm, and the average annual growth of tree height is 3.2-4 m. The survival rate of 107 young seedlings is general. It's all at 90%. Zhonglin 2001 Yang Zhonglin Beijing 2001 Yang and other excellent cultivars are well-established tree species cultivated by Professor Huang Dongsen, a famous forestry breeding expert. The general characteristics of this line are strong adaptability, fast growth, and no flying flocks in the spring. It is the best choice for urban and rural afforestation and fast-growing timber forests. Zhonglin Beijing 2001 Yang Neng-33 degrees low temperature, adaptability, wide adaptability, the species grows fast, per hectare of material up to 60-75 cubic meters; five-year trunk diameter up to 22-35 cm, growth According to the increase of 10-20% in the Italian 69 Yang, if afforestation of 1,000 hectares, it can meet the raw material needs of the 200,000 tons pulp mill. Zhonglin Beijing 2001 Yang Weixiong strains do not produce flying flocks in spring, which can reduce the pollution of urban air environment. The rapid growth of fast-growing poplars can make the trench wounds left on the tree trunks healed quickly when they lay eggs, and the eggs will be killed during the healing process. According to the statistics of experts, the effect of fast-growing and self-preserving pest control can reach 31-48%. The fast-growing fast-growing Yang is a deciduous tree with a tree height of up to 30 meters. The fast-growing poplar developed by Xinjiang Tianyan Biotechnology Development Co., Ltd. can grow to 5-7 meters in one year and leaves 30 centimeters in width. It is praised as a miracle in the history of poplar breeding in the world. This fast-growing poplar has the advantages of rapid growth rate, large amount of accumulated material, wide range of applications, low temperature resistance, sand resistance, and the like. The fast-growing poplar-shaped rods are straight and full, the skin color is grass green, the leaves are hypertrophic, the leaf gelatin is medium, the leaf shape is deep heart-shaped, and it is hairless. The tree grows to 7 meters a year, and the average diameter of the trunk exceeds 3 cm.
The yellow mealworm is not only rich in protein, fat, polysaccharid and other organic macromolecular nutrients, but also rich in phosphorus, potassium, iron, sodium, aluminum and other trace elements. For every 100g of the yellow mealworm larvae, the protein content of dry powder is between 48% and 54%, the fat content is between 28% and 41%, and the contents of vitamin E, B1 and B2 are also high. Therefore, the yellow mealworm can provide high quality protein for the earthworm.
