Occurrence Patterns and Control Methods of the Rice Water Fly in the Aksu Region
The rice water fly (Ephydra macellaria Egger) belongs to the order Diptera, family Ephydridae. It occurs extremely severely in newly reclaimed salinized rice areas and is one of the major pests in rice production in the Aksu region. The insect gnaws on primary and secondary roots, causing poor development of rice seedlings or floating seedling death. Surveys of rice in the Aksu region from 2002 to 2003 found that yield losses in lightly infested fields reached 5.8%-8.1%, and in heavily infested fields reached 40.5%-56.1%, seriously affecting

What to Do When Rice Seedlings Suffer Fertilizer Burn? Master the Correct Remedial Methods
Blindly increasing the amount of chemical fertilizer applied will cause various physiological disorders in rice seedlings, making growth and development abnormal after transplanting. Applying excessive amounts of undecomposed organic fertilizer will also cause poor growth of rice. This kind of physiological disorder caused by excessive fertilizer application is "fertilizer burn." 1. Causes of fertilizer burn There are many causes of fertilizer burn in rice seedlings, which can be summarized into three: First, improper fertilization methods.
