Problems solved by technology

However, this method consumes a lot of energy, and the cycle process is exposed to external sunlight, which is easy to breed a large number of algae and directly affects the growth of hydroponic plants.
[0005] Therefore, there is a need to provide a fertilizer that can release nutrient solution stably, which can solve the problem of energy consumption caused by using a motor for flow circulation

Abstract

The invention discloses a colloidal granular fertilizer and a preparation method thereof. The preparation method comprises the following steps: mixing a water soluble fertilizer and a colloidal liquid to form a fertilizer aqueous solution, wherein the water soluble fertilizer comprises at least one selected from a group comprising KH2PO4, MgSO4.7H2O, MnSO4.4H2O, H3BO3, Na2B4O7.10H2O, CuSO4.5HO2, ZnSO4.7H2O, (NH4)6Mo7O24.4H2O, CO(NH2)2, Fe-EDTA and KNO3, the colloidal liquid comprises at least one selected from a group comprising agar, a xanthan gum, shellac, a cyanopsis tetrag onoloba gum, a natto gum, a pectin, a synthetic aqueous glue and poly (lactic-co-glycolic acid), and the colloidal liquid content in the fertilizer aqueous solution is 1.5-15 wt%; and adding the fertilizer aqueous solution to water with a temperature of 0-4 DEG C, such that the fertilizer aqueous solution is subjected to solidification molding.

Description

technical field [0001] The invention relates to a fertilizer and a manufacturing method thereof, in particular to a colloidal granular fertilizer for hydroponic cultivation and a manufacturing method thereof. Background technique [0002] The cultivation of traditional fruits and vegetables or flowers is generally done by soil cultivation. The way of soil cultivation is to place plants outdoors, which is easily affected by insect pests, light damage or weather factors, making the process of plant breeding and the specification of plant growth impossible to accurately control or predict, which often causes serious economic losses to farmers. loss. [0003] Based on the above reasons, a hydroponic planting that combines modern structural technology and agricultural nutrient solution technology, especially in the technical field of refined agriculture and high-economic crops, occupies a very high proportion and an important position. [0004] In hydroponic planting technology...
