Abstract

The invention discloses compound fertilizer specially used for the potato and a method for preparing the same. The compound fertilizer comprises saturated aqueous solution of zinc salts of organic acid, saturated aqueous solution of calcium salt of organic acid, saturated aqueous solution of ferrum salt, saturated aqueous solution of boron-containing compound and surfactant. The method for preparing the compound fertilizer comprises the following steps: mixing evenly the saturated aqueous solution of zinc salts of organic acid and the saturated aqueous solution of calcium salt, adjusting the pH value of the mixture to 7.4-8.5, adding the saturated aqueous solution of ferrum salt, the saturated aqueous solution of boron-containing compound and the surfactant and evenly mixing the saturatedaqueous solution of ferrum salt, the saturated aqueous solution of boron-containing compound and the surfactant with the mixture. Before being applied, the compound fertilizer is evenly mixed with water and then is sprayed on the surfaces of the potato leaves or irrigated to the roots of the potato plants. The biorational compound fertilizer can meet the need of balancing the nutrition of the potato plants, improve the stress resistance of the potato plants, realize the high quality, the high efficiency and the high yield of the potatoes and meet the need of the scale planting and the healthydevelopment of the potatoes.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a special compound fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potatoes are underground tubers rich in carbohydrates, which can be used as food and vegetables, and produce starch, alcohol, etc. It has high nutritional value and is the fourth most important food crop in the world after wheat, rice, and corn. Potatoes are rich in vitamins A and C and minerals. The content of high-quality starch is more than 16%, vitamin C is 4 times that of tomatoes, and it also contains a lot of lignin. It is known as the "second bread" for humans, and its market potential is huge. considerable. Potato is not only an important food crop (especially in the western region), but also a high-efficiency crop for exporting foreign exchange, and it is also one of the important raw materials for the starch industry because of its resistance to stress, wide adaptability,...
