Problems solved by technology

[0002] At present, the average utilization rate of nitrogen fertilizer is low, the loss of nutrients is serious, and it is easy to cause pollution to groundwater and rivers and lakes; conventional nitrogen fertilizer is generally not easy to control the release rate of nitrogen, so that the release rate can be synchronized with the progress of nitrogen absorption by crops, so if a large amount of nitrogen fertilizer is applied at one time Nitrogen fertilizer is easy to cause burnt seedlings at the seedling stage, and it is often difficult to topdress the fertilizer multiple times due to the limitation of manpower and cultivation conditions, resulting in poor growth of crops due to lack of fertilizer
At present, the utilization rate of nitrogen fertilizer is low, not only because the rate of nitrogen fertilizer used in general chemical fertilizers is not easy to control, but also because the soil quality in different regions is different, so the utilization rate of nitrogen fertilizer is not the same

Abstract

The long-acting slowly released nitrogen fertilizer consists of ammonium nitrogen fertilizer 22-25 wt%, soil conditioner 19-21 wt%, composite sodium nitrophenolate powder 0.01-0.03 wt% and stuffing 50.98-60.98 wt%. The soil conditioner consists of fulvic acid and amino acid mainly; the composite sodium nitrophenolate powder consists of 5-nitroguaiamar sodium, one-nitrophenol sodium and p-nitrophenol sodium; and the stuffing is soil, organic fertilizer or inorganic fertilizer. The present invention has the beneficial effects of synchronous release of nitrogen with crop' s absorption, high fertilizer utilization rate, effective activation of phosphate and potash fertilizer in soil, no side effect and fertilizer effect higher than that of single nitrogen fertilizer.

Description

technical field [0001] The invention relates to a nitrogen fertilizer composition, in particular to a long-acting slow-release nitrogen fertilizer. Background technique [0002] At present, the average utilization rate of nitrogen fertilizer is low, the loss of nutrients is serious, and it is easy to cause pollution to groundwater and rivers and lakes; conventional nitrogen fertilizer is generally not easy to control the release rate of nitrogen, so that the release rate can be synchronized with the progress of nitrogen absorption by crops, so if a large amount of nitrogen fertilizer is applied at one time Nitrogen fertilizer is easy to cause burnt seedlings at the seedling stage, and often due to the limitation of manpower and cultivation conditions, it is difficult to do multiple topdressing, resulting in poor growth of crops due to lack of fertilizer. At present, the utilization rate of nitrogen fertilizer is low, not only because the rate of nitrogen fertilizer used in g...
