Rice seedlings are not dwarfed and may be caused by a variety of reasons, such as zinc deficiency, improper management of fertilizers and water, etc., and the need to identify the reasons to take targeted micronutrient fertilizers, strengthen management and other measures to promote recovery. In recent years, rice black-streaked dwarf disease in transplanted rice areas along the Huaihe River and Huaibei Province has occurred more severely. Its main characteristics are short dwarfing after rice transplanting, short leaf spacing, and dark green leaves, usually until July. In the middle and later part of the diseased plants, waxy white strips can be detected on the back. The diseased plant cannot grow normally and has strong heading. After the onset of disease, there are no effective measures to remedy the problem. The loss of production is huge and should be highly valued. For rice black-streaked dwarf disease, it is mainly necessary to use meticulous medication before and after wheat harvest to control the transmitted insects Laodelphax striatellus transferred from rice fields into rice fields. After transplanting rice, early inspections, early detections, and early measures should be taken before the end of June and beginning of July. For mild diseased fields, the diseased plants can be stepped into the mud, and the seedlings can be planted from the health point to the severely deficient seedlings; for the severe diseased field, the seedlings in the 5-6 leaf stage can be taken from the nearby direct-seeded rice fields. , Or choose live rice varieties with short growing periods to minimize losses. Generally after July 10, it is difficult to take effective remedial measures. Immunology Analyzer,Immunology Products,Rapid Blood HIV Test,Immunology Elisa System ZSL MED , https://www.zslmed.com
