Composite fertilizer suitable for planting vegetables and preparation method thereof

Abstract

The invention discloses a composite fertilizer suitable for planting vegetables and a preparation method thereof. The composite fertilizer is characterized in that the composite fertilizer is prepared from the following raw materials in parts by weight: 60-80 parts of urea, 40-50 parts of ammonium sulfate, 80-90 parts of potassium sulfate, 15-18 parts of manganese sulfate, 10-15 parts of borax, 10-12 parts of ammonium molybdate, 5-7 parts of nitro-fulvate, 45-55 parts of diammonium phosphate, 80-100 parts of argy wormwood, 100-140 parts of vervain, 200-250 parts of iris laevigata and 8-10 parts of soil improver. The formula of the invention is designed according to the nutritional requirements of the vegetables, and high nitrogen makes a contribution to improving the yield of the vegetables. The soil improver in the composite fertilizer disclosed by the invention contains a jade component, and the jade component contains a large number of trace elements which are beneficial to human bodies; simultaneously, the composite fertilizer disclosed by the invention can effectively adsorb and cure toxic heavy metal elements in soil, reduce the absorption of the heavy metal elements by crops and improve the yield of the crops.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a compound fertilizer suitable for vegetable planting and a preparation method thereof. Background technique [0002] Vegetables are rich in vitamins, and they consume a large amount of food in people's daily life. They are equally important to food in the human diet structure, and their output and planting area have a clear upward trend. It plays an important role in people's livelihood and national economy. The economic benefits of vegetables depend on the yield and production cost of vegetables. The high quality of vegetables is the goal that people relentlessly pursue. Effective use of limited land resources to improve the yield and quality of vegetable crops is the direction of people's efforts. Vegetables are crops that require a lot of nitrogen fertilizers, and most of the nitrogen elements need to be absorbed during the growth process. Nitrogen fertilize...
