Fertilizer containing additive KCO

Abstract

The invention discloses a fertilizer containing additive KCO, which comprises the following compositions in percentage by weight: 85 to 95 percent of fertilizer, and 5 to 20 percent of additive KCO, preferably 85 percent of fertilizer and 15 percent of additive KCO, wherein the additive KCO is prepared from compound potassium nitrophenolate (molecular formula: KC7H6NO4), compound sodium nitrophenolate (C6H4NO3Na) and polyaspartic acid (O-pasp) by way of chelating. The additive KCO-containing fertilizer of the invention has the advantages: the fertilizer can adjust the speed of NPK release, so that the NPK can be absorbed and utilized by the plants better; and the fertilizer can activate invalid phosphorus and invalid environment in the environment, without any side effect; and compared with general fertilizers, by using the fertilizer of the invention, the leaf surfaces of the plants are deep green and does not yellow, therefore, the fertilizer of the invention has a better effect.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a fertilizer containing additive KCO. Background technique [0002] At present, chemical fertilizers include compound fertilizers, nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, BB fertilizers and other fertilizers. However, the average utilization rate of these conventional fertilizers is low, the loss of nutrients is serious, and they are easy to pollute groundwater, rivers and lakes. Moreover, fertilizers are generally not easy to control the release rate of each nutrient, so that the release rate is synchronized with the progress of crops absorbing nutrients. Therefore, if a large amount of fertilizer is applied at the seedling stage, it is easy to cause seedling burn, and it is often difficult to do so due to the limitation of human cultivation conditions. To repeated topdressing, resulting in poor growth of crops due to lack of fertilizer. At present, the...

Problems solved by technology

[0002] At present, chemical fertilizers include compound fertilizers, nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, BB fertilizers and other fertilizers, but the average utilization rate of these conventional fertilizers is low, the loss of nutrients is serious, and it is easy to pollute groundwater, rivers and lakes

Moreover, fertilizers are generally not easy to control the release rate of each nutrient, so that the release rate is synchronized with the progress of crops absorbing nutrients. Therefore, if a large amount of fertilizer is applied at the seedling stage, it is easy to cause seedling burn, and it is often difficult to do so due to the limitation of human cultivation conditions. to repeated topdressing, resulting in poor growth of crops due to lack of fertilizer

At present, the utilization rate of nitrogen, phosphorus, and potassium is low, not only because the effective nutrient utilization rate used in general chemical fertilizers is not easy to control, but also because the soil quality in different regions is different, so that the utilization rate of nitrogen, phosphorus, and potassium in chemical fertilizers is also different. exactly the same
