Preparation method and application of leaf vegetable nano leaf fertilizer

Abstract

The invention discloses a preparation method of a leaf vegetable nano leaf fertilizer. According to the method, raw materials are smashed and decomposed into nano-scale materials through high-temperature stirring, electron beam irradiation and ultrasonic treatment based on lignin containing a net structure and active radicals in papermaking black liquid, and the adsorptive property of the lignin is increased, so that a phosphate fertilizer, a nitrogen fertilizer, a potash fertilizer, imino disuccinate chelated microelements, two conditioners such as rapin and biochemical fulvic acid and nanometer titania are adhered and bonded together to prepare the leaf vegetable nano leaf fertilizer. The preparation technology is simple, low in cost and high in controllability, the prepared leaf vegetable nano leaf fertilizer is scientific in proportioning of the raw materials and high in total nutrient content, the product is mixed with water, the mixture is sprayed and applied onto leaves of leaf vegetables, so that on one hand, nutrients of the leaf fertilizer can be fixed on the leaves, drifting, leaching loss and evaporation of the fertilizer are reduced, on the other hand, nutrient absorption and movement inside the leaves of the leaf vegetable fertilizer can be promoted, and the absorption and utilization rate is high.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer production, and in particular relates to a preparation method and application of leaf vegetable nanometer foliage fertilizer. Background technique [0002] Leafy vegetables are a type of vegetables with fat and tender leaves and petioles as edible parts. The common ones are cabbage, green leafy vegetables, onions and leeks, and sprouts. Cabbage includes Chinese cabbage, head cabbage, etc. Green leafy vegetables Vegetables include spinach, celery, rape, coriander, lettuce, fungus, shepherd’s purse, amaranth, chrysanthemum, fennel, etc. Onions and leeks include leeks, garlic sprouts, etc. Sprouts include pea sprouts, chicory sprouts, buckwheat sprouts, radish sprouts, etc. . Leafy vegetables are the most diverse category of vegetables, containing a large amount of vitamins, riboflavin, carotenoids, cellulose, protein, carbohydrates and calcium, iron, potassium and dietary fiber and other excellen...

Problems solved by technology

[0004] However, due to the immature technology and technology, the commonly used foliar fertilizers have the following disadvantages: one is that the foliar fertilizers have insufficient adhesion on the leaves of leafy vegetables, and the nutrients sprayed on the leaves are easily exposed to wind. Drifting, leaching, and volatilization under the action of blowing, raining, and sunlight will cause serious fertilizer loss, short duration, low utilization rate, and environmental pollution; the second is the foliar fertilizer sprayed on leafy vegetables. After the foliage, the nutrient elements need to be absorbed into the vegetable body through the cuticle of the foliage, while the absorption efficiency of common foliar fertilizers is low, and the internal mobility after absorption is poor, resulting in low effective utilization of foliar fertilizers And the nutritional imbalance of various parts of leafy vegetables
