The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow. 75 cm cell culture flask,t75 cell culture flask,suspension cell culture flask Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yonyuebio.com
Preventive measures: Add boron fertilizer to sandy loam soil, apply 1 kg of boron fertilizer to 667 square meters (1 mu), apply with other fertilizers as base fertilizer, or spray 0.2%-0.3% boric acid solution in the mid-season of radish. Second; deep ditch sorghum, digging and weeding, multi-application of organic fertilizer to prevent soil compaction; avoid continuous cropping with cruciferous vegetables; soil disinfection before sowing, seedling stage with 72% agricultural streptomycin sulfate wettable powder 4000 times liquid or 14 The solution of the ammonia-copper solution 300 times was sprayed once every 3-7 days, and sprayed 3-4 times continuously.

Diagnosis and prevention of boron deficiency in spring radish
When radish is planted in spring, if it is not properly used, it is easy to produce "black skin" and "black heart" phenomenon, which causes the radish to partially or completely lose its commerciality. Prevention and control of spring radish "black skin" and "black heart" is one of the important techniques for spring radish. The main cause is the lack of boron in sandy loam soil; the water staining or stagnation of the land; and black rot.
