Problems solved by technology

Therefore, the lack of potassium in organic fertilizers has greatly affected the harvest of crops
[0004] Generally speaking, crops have a long growth cycle, and it takes a long time from planting to fruiting and harvesting. During this period, a stable supply of potassium fertilizer is required. Therefore, how to improve the ability of crops to resist drought, cold, lodging, and pests? An organic ecological fertilizer containing long-acting potassium fertilizer is an important research content in the field of fertilizers

Embodiment 1

[0026] Prepare long-acting potash fertilizer granules A.

[0027] Potassium chloride solution with a concentration of 0.2M was prepared, ZSM-5 molecular sieves were immersed in the potassium chloride solution, and after standing for 24 hours, the solid was filtered and dried at room temperature to obtain the long-acting potassium fertilizer granules.

[0028] Wherein, the pore distribution of the ZSM-5 molecular sieve used is bimodal, and the specific surface area is 60m 2 / g, the pore volume is 0.2ml / g, and the mesopores with a pore diameter of 20-40nm account for 40% of the total pore volume, and the macropores above 100μm account for 35% of the total pore volume.

Embodiment 2

[0030] Prepare long-acting potassium fertilizer granules B.

[0031] Potassium chloride solution with a concentration of 0.6M was prepared, ZSM-5 molecular sieves were immersed in the potassium chloride solution, and after standing for 36 hours, the solid was filtered and dried at room temperature to obtain the long-acting potassium fertilizer granules.

[0032] Wherein, the pore distribution of the ZSM-5 molecular sieve used is bimodal, and the specific surface area is 80m 2 / g, the pore volume is 0.4ml / g, and the mesopores with a pore diameter of 20-40nm account for 50% of the total pore volume, and the macropores above 100μm account for 35% of the total pore volume.

Embodiment 3

[0034] Prepare organic ecological fertilizer granule A.

[0035] (1) Crush the crop straw to 80 mesh, add water to form a straw suspension, add potassium hydroxide to the suspension, mix well and carry out hydrothermal carbonization at a temperature of 280°C, control the reaction time to 40 hours, and then cool naturally To room temperature to obtain the suspension after hydrothermal carbonization, and set aside; during the hydrothermal carbonization process, the crop straw forms pores inside it, and the potassium element is adsorbed in the pores;

[0036] (2) 30 parts by weight of the hydrothermally carbonized suspension obtained in step (1), 180 parts by weight of soybean cake powder, 10 parts by weight of glucose, and 100 parts by weight of water, adjust the pH value of the material to 6.8, stir for 4 hours, and stir simultaneously Use ultraviolet light to irradiate and sterilize, then add 2 parts by weight of enzyme strains and stir evenly;

[0037] (3) Input the material...

Abstract

The invention discloses organic ecological fertilizer containing potash fertilizer with long-term effectiveness. The organic ecological fertilizer is prepared from long-term effectiveness potash fertilizer granules and organic ecological fertilizer granules in a weight ratio of (1 to 5) to (30 to 100), granulating, passing through a sieve with the size of 2 to 4mm for sieving and then packaging. The application method of the organic ecological fertilizer containing the potash fertilizer with the long-term effectiveness is that 90 to 155Kg of the organic ecological fertilizer containing the potash fertilizer with the long-term effectiveness is applied in land per mu. The organic ecological fertilizer containing the potash fertilizer with the long-term effectiveness, disclosed by the invention, has the advantages of the organic ecological fertilizer; according to the organic ecological fertilizer containing the potash fertilizer with the long-term effectiveness, the soil productivity can be improved, an environment benefiting the growth of microorganisms is created, the yield of crops is increased, and the quality degradation of soil is prevented; the organic ecological fertilizer containing the potash fertilizer with the long-term effectiveness has the capability of releasing potash element at long-term effectiveness, so the supply of the potash fertilizer during the growth cycle of the crops can be realized.

Description

technical field [0001] The invention relates to the field of organic ecological fertilizer preparation, in particular to an organic ecological fertilizer containing long-acting potassium fertilizer and its application method. Background technique [0002] The per capita arable land area in my country is lagging behind in the world. In order to increase crop yields, chemical fertilizers are usually used in large quantities. Although crop yields have been increased in the short term, chemical fertilizers have caused large-scale soil damage, low soil fertility, and low production in the long run. Deterioration of quality, near-death of beneficial soil microorganisms, and resistance of pathogens to chemicals have serious consequences. [0003] In response to the above defects of chemical fertilizers, organic ecological fertilizers have developed rapidly in recent years, and their development is also a key measure for the production of green food and sustainable agriculture.
