Problems solved by technology

[0005] Therefore, the technical problem to be solved in the present invention is to overcome the problems in the prior art that the loss of ammonia nitrogen fertilizer is easily caused due to the alkalinity of the biomass charcoal material, the restriction of the application range of fertilizer by crops avoiding chlorine, the excessive content of nitrate in crops, and the low hardness of fertilizer. It is easy to be damaged when it reaches the standard, and the vegetables have poor drought resistance and other defects. At the same time, combined with the characteristics of fertilizer requirements of various leafy vegetables, a special biochar-based fertilizer for leafy vegetables and its preparation method are provided.

Abstract

The invention belongs to the technical field of fertilizers, in particular to a special biomass carbon-based fertilizer for leaf vegetables and a preparation method thereof. The fertilizer is preparedfrom the following raw materials in parts by weight: 200-300 parts of urea, 200-300 parts of potassium sulfate, 120-180 parts of monoammonium phosphate, 150-200 parts of biomass carbon, 40-50 parts of a filler and 20-30 parts of an adhesion promoter, wherein the biomass carbon is treated through wood vinegar spaying. The special biomass carbon-based fertilizer for leaf vegetables can reasonably and sufficiently provide nitrogen-potassium nutrients needed for crops, avoids fertilizer needing characteristics of chlorine-avoiding crops in formula, is more scientific and reasonable in formula, and is wider in applicability.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special biochar-based fertilizer for leafy vegetables and a preparation method thereof. Background technique [0002] The nutritional value of leafy vegetables cannot be replaced by vegetables such as rhizomes, and they have high vitamin and calcium content, which is especially suitable for pregnant women and children. Leafy vegetables include two categories. The first category is edible vegetables with young leaves and stems, such as cabbage, celery, spinach, amaranth, lettuce, etc., which are called green leafy vegetables; the second category is edible leafy vegetables. Vegetables, such as head cabbage, Chinese cabbage (head cabbage), cauliflower, etc., are called head leafy vegetables. Although there are many varieties of leafy vegetables, they have commonalities in terms of nutritional requirements: (1) In terms of the absorption of the three elements, nitr...
