Porous nutrient brick for fruit trees

Abstract

The invention discloses a fruit-tree fertilizer in a porous brick form, which is prepared by mixing 50-70% of organic fertilizer, 10-20% of nutrient element, 15-30% of binding material and 1-5% of plant material in percentage by weight to make a brick which is 15-30 cm long, 10-20 cm wide and 5-10 cm high, wherein the width surface of the brick is evenly distributed with 4-12 pores which perpendicularly penetrate through the brick, and the diameters of the pores are 2-5 cm. The fertilizer has the advantages of easy obtainment of raw materials, simple production technique, convenient operation, comprehensive nutrient content and long effective period; when in use, the porous nutrient brick can be entirely embedded into soil; the porous nutrient brick is suitable for requirements of fruit trees; and the nutrient content is slowly dissolved and released, and then can temporarily stay in the pores, therefore being not easy to run off.

Description

(1) Technical field [0001] The invention relates to a new type of special fertilizer for fruit trees, which belongs to the field of fertilizer processing. (2) Background technology [0002] The fertilizers used in fruit tree production are mainly powdery and granular, and other types of fertilizers are less. Usually powdery and granular nutrients are relatively simple, and they need to be proportioned according to the nutritional needs of fruit trees when used. The technical requirements are relatively high, and it is difficult for ordinary farmers to master. The nutritional components of various compound fertilizers for fruit trees are relatively comprehensive, but this type of fertilizer is also mainly powdery and granular, which will be blown away in strong winds during use, which is unhygienic and inconvenient; moreover, the soluble nutrients in powdery and granular fertilizers The release is relatively fast, easy to lose, and the utilization rate is low, especially whe...

Problems solved by technology

Usually powdery and granular nutrients are relatively simple, and they need to be proportioned according to the nutritional needs of fruit trees when used. The technical requirements are relatively high, and it is difficult for ordinary farmers to master

The nutritional components of various compound fertilizers for fruit trees are relatively comprehensive, but this type of fertilizer is also mainly powdery and granular, which will be blown away in strong winds during use, which is unhygienic and inconvenient; moreover, the soluble nutrients in powdery and granular fertilizers The release is relatively fast, easy to lose, and the utilization rate is low, especially when encountering a large amount of rainfall or irrigation, it will bring certain pollution and loss of nutrients

[0003] Although the patent "Special Nutrient Block for Fruit Trees (Application No. 94115194)" is a non-powdered and granular fertilizer, it uses "potassium chloride" as a source of potassium, and many fruit trees avoid "chlorine" plants, such as apples, citrus, grapes, etc. etc. are very sensitive to chloride ions. After applying chloride-containing fertilizers, the roots are easy to burn, the sugar content of the fruit is reduced, the acidity is high, and the flavor is not good. , the nutrient block is fragile during handling

In addition, the "nutrition block for fruit trees" is solid and lacks holes for water and gas storage; the nutrient block is fragile, and the soluble nutrients in the block are still released and lost as quickly as ordinary fertilizers after being broken
