The Effects of Potassium Silicate Hydrate Mixing Urea on the Growth and Development in Winter Wheat

摘要

In order to increase the fertilizer use efficiency, the effects of Potassium Silicate Hydrate (PSH) mixing urea on the growth and development in winter wheat are rarely to be studied. So the effects of the same amount of PSH mixing different quantity of urea on the growth and development in winter wheat have been done to investigate the role which PSH plays during the fertilizer of urea working. The results indicate that the effect on root-shoot ratio in wheat display dissimilarly among different treatments, on root activity is more effective than without urea, on malondialdehyde (MDA) is to reduce its content and on proline content is conducive to the accumulation. Overall, the effects of treatment 2 (T2) which 5 kg/667 m~2 PSH mixing 30 kg/667 m~2 urea are better than other treatments, so T2 can be taken as the suitable application. This will be of great significance for the efficient and safe application of PSH and urea.
