Effects of side-deep placement of fertilizer on rice yield and nutrient absorption
Deep application of fertilizers is a common strategy to improve grain yield and nitrogen use efficiency.In view of the variety of fertilizer and the variety of fertilizer application methods in Linhai area,this study studied the effect of different fertilizer and different fertilizer application methods on rice yield and soil fertility through field random block experiment.The results showed that the side-deep placement of Huiduoli compound fertilizer(HS)and the side-deep placement of Huiduoli compound fertilizer reduction(HSJ)had obvious effects on rice yield increase;while the one-time side-deep placement of Moith slow-release fertilizer(MSY)significantly increased the nitrogen content of rice.Therefore,rice yield and nutrient uptake were significantly affected by fertilizer types and fertilization methods.In terms of soil nutrients,the effect of Moith slow-release fertilizer reduction and side-deep placement(MSJ)significantly increased pH value,and also significantly increased soil organic matter,total nitrogen,available phosphorus,and available potassium.HS and HSJ fertilization treatments showed significant efficiency gains in plant height and spike length and significantly increased rice yield,which is recommended for subsequent agricultural production.
