Description

Technical field:

[0001] The invention belongs to the technical field of special fertilizer for plants and its preparation, and relates to a special fertilizer for potato polymerization and a preparation method thereof. Background technique:

[0002] Potatoes, also known as ground beans, potatoes, yams, etc., are annual herbaceous plants of the family Solanaceae and are the fourth major food crop in the world, second only to rice, wheat and corn. Potato has many advantages such as wide adaptability, high and stable yield, and comprehensive nutrition. It is known as the "second bread" of human beings. However, in recent years, with the excessive application of chemical fertilizers and pesticides, it has brought great pollution hazards to soil, water sources, and the atmosphere, and the yield and quality of potatoes have declined significantly.

[0003] At present, in the current situation of potato fertilizers, organic fertilizers, chemical fertilizers, and biological bacteri...

Examples

Embodiment 1

[0022] This example relates to a special fertilizer for potato polymerization, which is prepared from raw materials containing water-absorbing polymer monomers, inorganic nutrients, catalysts, crosslinking agents and initiators; wherein the water-absorbing polymer monomers are 160 g of acrylic acid; the inorganic nutrients are 160g urea, 320g monoammonium phosphate, 480g potassium sulfate, 48g calcium sulfate, 48g magnesium sulfate, 56g sodium silicate, 8g ferrous sulfate, 8g sodium borate, 8g copper sulfate, 8g ammonium molybdate, 8g manganese sulfate and 8g zinc sulfate The catalyst is 160g of potassium hydroxide aqueous solution with a pH value of 8.0; the crosslinking agent is 80g of ethylene glycol; the initiator is 40g of potassium persulfate.

Embodiment 3

[0036] The present embodiment is the field experiment of the special fertilizer for potato polymerization prepared in Example 1, and the concrete experimental process is as follows:

[0037] A piece of soil was selected for testing in a certain rural area, and the potato field planting experiment was carried out in different areas. The watering conditions and field management measures of the experimental group and the control group were the same, only the fertilizer application and fertilization methods were different.

[0038] Experimental group: No treatment was performed on the test soil, and the special fertilizer for potato polymerization in Example 1 was applied at a rate of 30 kg / mu during sowing, and applied at one time.

[0039] Control group: According to the conventional potato planting method, the soil was first treated with organic fertilizer, and then the conventional fertilizer (15-15-15NPK compound fertilizer) was applied once at the time of sowing according to ...
