Embodiment 1

[0023] (1), take 0.1 part of sodium humate, 0.30 part of borax, 0.2 part of ferrous sulfate, 20 parts of water, and 20 parts of landfill leachate by weight and add them to a closed mixing tank, fully Stir and mix, depending on the foam situation, add silicone defoamer as appropriate to eliminate foam. The stirring time is 40 minutes. At the same time, start the centrifugal pump equipped with a high-energy magnetizer for cyclic magnetization. Minutes or more, take the supernatant and set aside;

[0024] (2), put the supernatant of the mixed liquid obtained in step 1 into a closed reaction stirring tank, add 8 parts of ammonium dihydrogen phosphate, 7 parts of potassium chloride, and 0.3 parts of citric acid into the mixed liquid in the reaction tank , at a stirring speed of 100 rpm, the stirring time is 30 minutes. Depending on the foam situation, silicone defoamer is added to eliminate foam. While stirring, a centrifugal pump equipped with a high-energy magnetizer is started f...

Embodiment 2

[0028] (1) Take 0.2 parts of sodium humate and potassium humate in a ratio of 1:1, 0.2 parts of borax, 0.15 parts of ferrous sulfate, and 0.15 parts of magnesium sulfate by weight, and add 50 parts of landfill leachate to the closed In the mixing tank, fully stir for 60 minutes at a stirring speed of 150 rpm. Depending on the foam situation, add silicone defoamer to eliminate foam. At the same time, start a centrifugal pump equipped with a high-energy magnetizer with a central magnetic field strength of 22,000 Gauss for cyclic magnetization. , and then put it into the sedimentation tank for 30 minutes, and take the supernatant for later use;

[0029] (2), put the liquid obtained in step (1) into a closed-end reaction stirring tank, mix 8.5 parts of ammonium dihydrogen phosphate, 8.5 parts of potassium sulfate, 0.35 parts of citric acid, 0.75 parts of compound amino acid powder, 0.01 part of zinc sulfate, Add 0.2 parts of manganese sulfate and 0.015 parts of copper sulfate into...

Embodiment 3

[0034] (1), by weight, take 0.2 parts of sodium humate, potassium humate or a mixture of the two in any proportion, 0.8 parts of compound amino acid powder, 0.3 parts of borax, 0.1 part of ferrous sulfate, 0.1 part of magnesium sulfate, landfill leachate Add 45 parts into a closed mixing tank, fully stir and mix at a stirring speed of 140 rpm, add silicone defoamer as appropriate to eliminate foam according to the foam situation, stir for 50 minutes, and start a high-energy magnetizer at the same time The centrifugal pump is used for circular magnetization, the central magnetic field strength is 25000 gauss, and then put into the sedimentation tank for 60 minutes, and the supernatant is taken for use;

[0035] The above-mentioned landfill leachate preparation process is as follows: the collected domestic waste and water are mixed and soaked at a ratio of 1:1 by weight for more than 1 hour, passed through a 0.5mm sieve, and the permeate is taken.

[0036] (2), put the mixed liq...

Abstract

The invention discloses a method for preparing a highly-efficient magnetized liquid compound fertilizer for drip irrigation and a liquid compound fertilizer prepared by the method. The method comprises the following steps: sodium humate, potassium humate, water or landfill leachate, ammonium biphosphate, potassium chloride or potassium sulfate, urea and ammonia are stirred and chelated; simultaneously, under the condition that the strength of a central magnetic field is more than or equal to 20,000 gausses, the mixture is magnetized; and the PH value of the mixture is adjusted to between 4 and 5 through concentrated sulphuric acid or concentrated nitric acid. Compared with the prior art, the liquid drip irrigation fertilizer has good dissolution and full nutrition, is very favorable for absorption by crops, greatly improves the utilization rate of the fertilizer and simultaneously causes no soil hardening.

Description

Technical field: [0001] The invention relates to a method for preparing a high-efficiency magnetized liquid compound fertilizer for drip irrigation and the prepared liquid compound fertilizer, in particular to a method for preparing a high-efficiency magnetized liquid compound fertilizer for drip irrigation that can effectively utilize the landfill leachate of urban domestic waste. The preparation method of fertilizer and the liquid compound fertilizer prepared therefrom. Background technique: [0002] With the large-scale promotion of micro-drip irrigation technology under plastic film and the support of national supporting policies, the improvement of benefits and effects brought by micro-drip irrigation has been accepted by the majority of farmers, especially in the northwest region, where there are many lands, few people, and Drought, therefore, is also the fastest and largest area of ​​drip irrigation in China. However, at present, the drip irrigation fertilizers used ...
