沼肥和化肥合理施用技术的研究,目的在于究竟有机和无机这两类肥料配合施用的效果。通过配合施用协调作物对营养元素的需要与土壤供肥之间的矛盾,达到提高产量、增加收入的目的:其次是研究在一定的气候土壤条件下,确定不同肥力土壤上的最佳配合比例,以便减少肥料投资,降低成本,获得最大的经济效益。第三,合理的配
The research on the rational application of biogas fertilizer and chemical fertilizers aims at exactly the effect of the two types of organic and inorganic fertilizers. Through coordinating the contradiction between the nutrient requirements of crops and supplying fertilizer to the crops, the purpose of increasing the yield and increasing the income can be achieved by cooperating with the application: secondly, to determine the optimal proportion of the soil with different fertility in certain climate and soil conditions, In order to reduce fertilizer investment, reduce costs and maximize economic benefits. Third, reasonable allocation
