Problems solved by technology

From the observation of the plant growth process, it can be concluded that the total effective rate of inorganic potassium fertilizers has not been fully utilized, so the phenomenon of potassium deficiency in plants is relatively serious. Plants are sick due to lack of potassium elements, and lodging is not uncommon. More importantly, the use of inorganic fertilizers for many years has made the soil harden to a certain level. degree

Embodiment Construction

[0012] The following examples illustrate the present invention further.

[0013] Optimal scheme 1 rice base fertilizer: take 60-80% of active straw ash, 25-35% of prepared bentonite, 10-15% of potassium humate, stir with a mixer for 35 minutes, granulate, and dry to obtain potassium carbonate grains as base fertilizer. Take 50% potassium carbonate grains, mix with 22% urea, 23% diamine phosphate,

[0014] Mixing is carried out to obtain an organic-inorganic base fertilizer. When used in paddy fields, it shows that the seedlings will not slow down, tillering ahead of time, the yield will increase by 13-15%, and the soil will be improved in the same year.

[0015] Preferred option 2: Take 50-70% of active straw ash, 15-20% of prepared bentonite, and 8-12% of potassium humate, stir with a mixer for 32 minutes, granulate, and dry. It can be used as base fertilizer and topdressing fertilizer to supplement potassium, silicon and zinc trace elements for various plants and improve ...

Abstract

The invention discloses a plant organic potash fertilizer and a preparation method thereof. The method comprises the following steps: carrying out acidity adjustment on straw ash adopted as a main raw material, complexing the acidity adjusted straw ash with sodium humate, and mixing the obtained complex with modified bentonite, turfy soil and potassium humate to prepare the organic potash fertilizer suitable for being used in different growth periods of rice, fruits and vegetables for a long term. High amounts of the potassium element and other various trace elements in the straw ash in the organic potash fertilizer can be easily absorbed by crops, and all above elements have no antagonism, can mutually promote and are difficulty immobilized by soil, so the effects of the fertilizer are fully performed. The fertilizer disclosed in the invention has the advantages of realization of reduction and full utilization of plant organic elements, no antagonism and mutual promotion of all the elements, soil hardening changing, and waste resource recycling.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, in particular to a plant organic potassium fertilizer and a preparation method thereof. Background technique [0002] Potassium fertilizers are mainly imported in my country, and most of them are inorganic potassium fertilizers. At present, a kind of biological potassium fertilizer has been produced in my country. Its function is to use biological fungi to promote the function of inorganic potassium. From the observation of the plant growth process, it can be concluded that the total effective rate of inorganic potassium fertilizers has not been fully utilized, so the phenomenon of potassium deficiency in plants is relatively serious. Plants are sick due to lack of potassium elements, and lodging is not uncommon. More importantly, the use of inorganic fertilizers for many years has made the soil harden to a certain level. degree. Contents of the invention [0003] The object of...
