Abstract

The invention relates to a long-acting slow release fertilizer special for tomatoes and a preparation method thereof. The long-acting slow release fertilizer special for tomatoes disclosed by the invention comprises the following components in parts by mass: 230 parts of nitrogen fertilizer active ingredients, 120 parts of phosphorus fertilizer active ingredients, 10 parts of potassium fertilizeractive ingredients, 92-100 parts of bentonite and 7-9 parts of a long-acting compound fertilizer additive, wherein the bentonite contains 85-90 percent by mass of montmorillonite; and the long-actingcompound fertilizer additive comprises the following components in parts by mass: 2-8 parts of quinhydrone, 3-25 parts of dicyandiamide, 0.1-0.8 part of complex rare earth and 70-95 parts of zeolite powder. The invention further provides a preparation method of the long-acting slow release fertilizer special for tomatoes. By applying the long-acting slow release fertilizer special for tomatoes disclosed by the invention, crop yield is increased by over 20 percent, and quality is enhanced remarkably. Nitrogen utilization ratio and phosphorus utilization ratio are increased greatly; and moreover, the long-acting slow release fertilizer special for tomatoes disclosed by the invention is safe for human beings, livestock and crops, and residues in soil and crops are avoided.

Description

Technical field [0001] The invention relates to a special long-acting slow-release fertilizer for tomato, and the invention also relates to a preparation method of the special long-acting slow-release fertilizer for tomato. Background technique [0002] Tomato requires less fertilizer in the early stage of growth, and the amount of fertilizer required in the peak period increases sharply; according to the various fertilizers required, it focuses on dinitrogen fertilizer in the early stage of growth, and potash fertilizer in the later stage, and phosphorus fertilizer is used throughout the growing period; the application of ordinary fertilizers needs to grow in the tomato During the period, topdressing was performed many times, and these fertilizer requirements of tomatoes could not be well satisfied. Therefore, it is necessary to provide a fertilizer suitable for its growth characteristics that does not require top dressing. Chinese Patent Application Publication CN1163449A disc...
