"Jujube has more than 3,000 years of planting history in China. China is the origin of jujube and the world's largest jujube producing area." Leader of the "Research and Demonstration of High-Efficiency Key Technologies for Jujube-forest Eco-regulation" Project Leader, Dean of Beijing Agricultural College Some years said, "This important economic crop has high nutritional value and high medicinal value. Especially, it can quickly bring income growth to farmers. Management is relatively simple and easy to promote." However, jujube It's a good thing to say. It's also true for insects. It seems that everyone has this experience: bite a date ... a worm manure! This guy who specializes in defecation in the heart of the jujube heart is called Peach. It is one of the world's pests. It not only harms jujube but also harms apple, pear, apricot and hawthorn and other fruit trees. This kind of peach borer, which everyone has seen, is a larva of a moth. The traditional method of prevention and control is the spraying of chemical pesticides, but the drawbacks brought about by this control method are: pesticide residues cause pollution to the environment and fruits. Every year, 20% to 30% of jujube forests are victimized, and the loss is more than several billion yuan. In the “Zhulin High-efficiency Ecological Regulation Technology†study, Beijing Agricultural College and related affiliated organizations identified a total of 129 species of herbivorous pests and 78 natural enemies of jujube forests in China, together with 74 new pests of jujube forest and 36 species of natural enemies. These achievements are brought together into a “food network structure map of jujube-forest pests and natural enemiesâ€. In a set of “efficient ecological regulationâ€, “controlling pests†is one of the key points, but the result is far more than this. “Zhaoshu will be a very important tree species for mountainous areas, old areas, poverty-stricken areas, and areas to be developed in the west.†Wang Younian said that in the 1990s, there were two pilot sites in Beijing in the early 1990s. One was the Changping Black Mountain Village. One is Pinghua Dahuashan, the development of several major characteristics of fruit, jujube is one of them. Another example is Aksu, Hetian, Xinjiang, jujube is now a leading industry in the region; the construction of 1,000 km of green belts in the Tarim Basin, the most important of which is dates, walnuts, such as dried fruit, it is necessary to obtain economic value, but also to solve desert problems. Another group of figures can easily prove the correctness of the phrase “science and technology are primary productive forcesâ€. After the comprehensive technology of ecological regulation has been promoted and applied in the Zaozuo region, the use of mu has been reduced from 18 to 7 times. The cost of prevention was reduced from 78 yuan to 46 yuan, the average yield per mu was increased by 29.31 kg, and the efficiency was increased by 103.67 yuan. The overall promotion and application area of ​​the project reached 12.7602 million mu, which increased production by 448 million kg, increased income by 1.02 billion yuan, and saved 420 million yuan in expenditure. The increase in revenue and expenditure totaled 1.422 billion yuan.
Flow Cytometry is an important tool in cell biology research.10,000 cells per second, the cell size, DNA content, extracellular proteins can be quickly, large throughput statistical analysis, divided into With high analysis sensitivity, more than ten parameters can be analyzed at the same time. It is known as the "CT" of biological laboratory.
