How to control stem rot of Euonymus tomentosa
Rot is a major disease of Populus tomentosa, which can cause the whole plant to die in serious cases. Under the influence of the special climate in winter and spring, the turning green of Euonymus tomentosa is not ideal, and some dead branches will appear, resulting in the weakening of the growth potential of Populus tomentosa, thus reducing the disease resistance of the plant. Some Euonymus tomentosa are prone to stem rot. In particular, the branches in 2012 suffered the most, the stem turned brown at the initial stage, the leaves lost green, the shoots drooped, and the leaves did not fall off. In the later stage, the damaged parts of the stem blackened, the cortex shrunk, the endothelial tissue rotted, and there were many small blackens.

Successful study on Water floating Seedling technique of Cotton
Cotton floating seedling technology, which has always been regarded as a "forbidden area", has been successfully broken through. The key problems of the 10th five-year Plan and the major project of the National "863"-- Cotton floating Seedling Technology, which was developed and developed by Hunan Agricultural University, passed the appraisal of the expert group a few days ago. Cotton has been a dry soil crop since it has been cultivated, and it is vulnerable to waterlogging, so the original cotton seedlings also regard floating seedlings as a forbidden area. Since 2000, the research team led by Professor Chen Jinxiang of Hunan Agricultural University began to "break the ban", after nearly five years of hardship.
