Problems solved by technology

Most of the ecological potassium fertilizers described in the above patents are mainly formed by simply mixing organic matter or organic waste residue with potassium fertilizers, and do not deal with the pollution of soil or water by potassium fertilizers such as potassium sulfate, resulting in leaching of potassium ions and loss of sulfate radicals. Its soil is acidified or compacted, the content of microorganisms and organic matter is low, and the soil fertility is reduced.

Abstract

The invention belongs to the field of crops fertilizers and in particular relates to an ecological potassium fertilizer and a preparation method of the ecological potassium fertilizer. The ecological potassium fertilizer is mainly prepared from potassium sulfate, pine bark, humic acid, urea and natural minerals. The pine bark is treated firstly to remove substances harm to the crops, and then the treated pine bark is mixed with potassium sulfate, humic acid, urea and natural minerals to obtain the ecological potassium fertilizer. The ecological potassium fertilizer mainly adopts natural organic matters and is environment-friendly, the quick-acting fertilizer can be provided for promoting the rapid growth of the crops, and the loss of a great amount of potassic fertilizer in soil can be avoided; and besides, the soil is improved, the soil caking phenomenon is improved, the organic matters in the soil are increased, the microorganism activity is improved, the stress-resistant and disease-resistant capability of the crops is improved, the successive cropping obstacle can be relieved after the fertilizer is applied year by year, the quality of agricultural products is improved, the environment pollution is reduced, and the ecological potassium fertilizer is safe and non-toxic to human, livestock and environment and is environment-friendly.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and more precisely relates to an ecological potassium fertilizer and a preparation method thereof. Background technique [0002] With the increase of the world's population, the problem of food production is an important issue in agricultural production. In order to increase food production, the use of chemical fertilizers is essential, mainly the use of nitrogen, phosphorus and potassium. Part of the nitrogen fertilizer in the soil is absorbed by crops, and the other part will be leached and lost in the soil through nitrogen fertilizer, especially nitrate, or nitrogen oxides will be emitted into the air through nitrification, causing serious pollution to water bodies and the atmosphere. There are also varying degrees of pollution. Potassium fertilizer exists in the form of ions in the soil, a small part of potassium fertilizer is absorbed by crops, and the rest is leached and lost, and its acc...
