Example Embodiment
[0046] Example 1: Environmentally friendly liquid fertilizer for soil improvement, the raw material components are as follows:
[0047] 25 parts of lignosulfonate, 10 parts of potassium humate, 10 parts of urea, 3 parts of zinc sulfate, 2 parts of sodium alginate, 70 parts of water.
[0048] The preparation method is as follows:
[0049] (1) Dissolve 25 parts of lignosulfonate and 10 parts of potassium humate in 70 parts of water, stir well and dissolve;
[0050] (2) Adjust the solution of step (1) to pH 7 with a concentration of 50wt% nitric acid;
[0051] (3) Add 10 parts of urea to the solution prepared in step (2) and stir to dissolve;
[0052] (4) Heat the solution in step (3) to 60°C, add 3 parts of trace element zinc sulfate, and stir until dissolved;
[0053] (5) After the solution prepared in step (4) is cooled, add 2 parts of sodium alginate to dissolve it, and get it.
[0054] The prepared environmentally friendly soil-improving liquid fertilizer is mainly applied to vegetable c...

Example Embodiment
[0064] Experimental example 1: The effect of environmentally friendly liquid fertilizer on potato
[0065] 1. Test location and nature of the tested soil
[0066] Test site: Taoyuan Town, Feicheng City, Shandong Province.
[0067] Test site soil: The plot is light loam, the basic physical and chemical properties of the soil are: organic matter (1.72%), alkali hydrolyzable nitrogen (23.90mg·kg) -1 ), available phosphorus (111.00mg·kg -1 ), quick-acting potassium (49.58mg·kg -1 ), pH 6.49.
[0068] 2. Test time: March 3, 2012 to August 10, 2012.
[0069] 3. Field test design:
[0070] There are 3 treatments in the experiment, namely: (1) control: no fertilizer; (2) habitual fertilization (obtained through field investigation): according to local farmers' fertilization amount and basal topdressing method (basic fertilizer is 20-12-22 compound fertilizer) 150kg / mu, 15kg / mu urea topdressing in the group stage); (3) Example 1 Environment-friendly liquid fertilizer: the base fertilizer is appl...
