Abstract

The invention relates to a special fertilizer for sweet potatoes. The special fertilizer comprises the following raw materials in parts by weight: 18-25 parts of urea, 12-18 parts of ammonium chloride, 8-12 parts of monoammonium phosphate, 6-10 parts of calcium superphosphate, 35-40 parts of potassium chloride, 10-12 parts of sodium humate, 5-8 parts of grondverbeteraar and 1-3 parts of a PH buffer agent, and the raw materials are mixed together according to the ratio. Compared with the prior art, the special fertilizer blends nutrient components according to the demands of sweet potatoes, the nutrient utilization rate is high, the disease resistance is improved, and the yield of the sweet potatoes is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a special chemical fertilizer for sweet potatoes. Background technique [0002] Sweet potato is one of the food crops in the north of my country. It has the advantages of strong adaptability, drought tolerance, less pests and diseases, and high yield. It is an ideal high-efficiency crop. According to analysis, every 500 kilograms of fresh sweet potatoes contain 1.75 kilograms of nitrogen, 0.9 kilograms of phosphorus, and 2.75 kilograms of potassium. Therefore, the main components required by sweet potatoes are the most potassium, followed by nitrogen, and the least phosphorus; The root tuber is enlarged, the starch content is increased, and it has the advantage of being resistant to storage. [0003] The "Special Fertilizer for Sweet Potato" with the application number of 200810001774.4 in the prior art has the following deficiencies: 1. It only provide...
