Effects of Different Amount of Manure Water on Wheat Yield and Soil Properties
In order to improve the utilization efficiency of manure in dairy cow farming enterprises and to clarify the effects of different amount of manure water on wheat growth and soil properties,an experiment was carried out in the base of Zhongjie Jingming Agricultural Development Company in 2021 and 2022.Five manure treatments of 0,150,300,450 and 600 m3/hm2 were designed.The plant height and yield of wheat and the soil PH,the contents of salinity,organic matter,al-kali-hydrolyzable nitrogen,available phosphorus,available potassium and heavy metals in soil under different treatments were compared and analyzed.The results showed that the performance of dung water treatment of 450 m3/hm2 was better.Compared with the treatment without dung water treatment,the wheat yield and soil organic matter content increased by 15.9%and 0.165%,respectively.The results showed that the rich content of nitrogen,phosphorus and potassium in fecal water could promote the growth of wheat and reduce the amount of fertilizer,and the application rate of 450 m3/hm2 manure water would not cause heavy metal pollution such as copper,chromium,cadmium and lead in soil in a short time.
