Embodiment 1

[0028] A humic acid long-acting compound fertilizer, which is prepared from the following raw materials in parts by weight:

[0029] Humic acid 20, bacteria agent 2, zeolite powder 4, magnesium powder 5, calcium powder 5, urea 15, monoammonium phosphate 10, potassium chloride 10.

[0030] The preparation method of this humic acid long-acting compound fertilizer, it comprises the steps:

[0031] Add humic acid and potassium chloride into the stirring tank and stir and mix for 15 minutes. When the temperature reaches 50°C, send the materials in the stirring tank into the reactor, add urea and monoammonium phosphate into the reactor, and feed Water with the same quality as urea, heat preservation reaction for 15 minutes to obtain a paste-like feed liquid; then send the paste-like feed liquid into a high-tower granulator, add zeolite powder, magnesium powder and calcium powder at the same time for granulation and drying, and then Add the bacterial agent, stir evenly with a mixer,...

[0048] Fertilizer test

[0049] Humic acid long-acting compound fertilizer has carried out crop fertilization experiments in the past three years, and the summary is as follows:

[0050] Humic acid long-acting organic-inorganic compound fertilizer has been practiced in several counties such as Junan County and Hedong District in Linyi. Compared with other multi-component organic fertilizers, humic acid long-acting compound fertilizer with the same amount of fertilizer is applied. The effect of increasing yield per mu is remarkable. Humic acid long-acting compound fertilizer was applied in various townships and towns in Feixian County from 2011 to 2012. It was applied to field crops such as corn and sweet potatoes, economic crops such as soybeans and green peppers, and fruits and vegetables such as melons, tomatoes, cabbage, grapes and pears. The results of field fertilizer demonstration experiments on a variety of crops such as , radish, etc. show that the long-acting humic a...

Abstract

The invention belongs to the field of fertilizers, and relates to a humic acid long-acting compound fertilizer which is prepared from the following raw materials in parts by weight: 20-25 parts of humic acid, 2-4 parts of microbial inoculum, 4-8 parts of zeolite powder, 5-10 parts of magnesium powder, 5-10 parts of calcium powder, 15-20 parts of urea, 10-15 parts of monoammonium phosphate and 10-15 parts of potassium chloride. The invention also discloses a preparation method of the humic acid long-acting compound fertilizer. The humic acid long-acting compound fertilizer provided by the invention can effectively control the loss of fertilizer and moisture, enhance the yield of the crops, and greatly lower the cost.

Description

[0001] technical field [0002] The invention belongs to the technical field of fertilizers, and in particular relates to a humic acid long-acting compound fertilizer and a preparation method thereof. [0003] Background technique [0004] After entering the 21st century, with the development of modern agricultural production, people are looking forward to the emergence of fertilizers with long-lasting fertilizer effects and less loss in the field of fertilizers, which can improve the soil, increase the yield and quality of crops, increase production efficiency, reduce production or improve labor. conditions and protect the natural environment. Due to the excessive use of soil, most of the soil currently has many problems, such as poor nutrient absorption capacity of crops, inactive soil, poor water and fertilizer retention capacity, serious soil salinization caused by successive years of sedimentation, serious soil-borne diseases, and trace Elements are not easily absorbe...
