Embodiment 1

[0076] Embodiment 1, metal-organic framework material fertilizer and preparation method thereof, preparation of compound I: take 1 mole of ferric chloride, 6 moles of phosphoric acid, 1 mole of oxalic acid, urea (CO(NH 2 ) 2 ) 3 moles, deionized water (H 2 O) Put 100 moles in a beaker and stir with a glass rod. After the reaction substrate is completely dissolved and mixed evenly, pour it into the reaction kettle and seal it completely. Set the reaction temperature to 100°C, and the reaction time is 24h. The stirring speed was set at 2°C / min, and the rotation speed of the stirring bar was set at 120 rpm. After the reaction was completed, the reaction kettle was opened when the temperature dropped to room temperature, the solution was filtered with filter paper, and then washed with deionized water for 3 times to obtain the product.

[0077] Nutrient release measurement method: accurately weigh 0.13g of urea, mix it with 300g of test soil, and then add it to a culture plate wi...

Embodiment 2

[0078] Embodiment 2, metal-organic framework material fertilizer and preparation method thereof, preparation of compound II: Weigh 1 mole of ferric chloride, 0.25 mole of zinc sulfate, 6 moles of phosphoric acid, 1 mole of oxalic acid, urea (CO(NH 2 ) 2 ) 3 moles, deionized water (H 2 O) Put 100 moles in a beaker and stir with a glass rod. After the reaction substrate is completely dissolved and mixed evenly, pour it into the reaction kettle and seal it completely. Set the reaction temperature to 100°C, and the reaction time is 24h. The stirring speed was set at 2°C / min, and the rotation speed of the stirring bar was set at 120 rpm. After the reaction was completed, the reaction kettle was opened when the temperature dropped to room temperature, the solution was filtered with filter paper, and then washed with deionized water for 3 times to obtain the product.

Embodiment 3

[0079] Embodiment 3 is basically the same as Embodiment 1, but with the following changes: the molar ratio of the metal-organic framework material composition is: ferric chloride (FeCl 3 ·6H 2 O) 0.25, phosphoric acid (H 3 PO 4 ) 5, oxalic acid (H 2 C 2 o 4 2H 2 O) 0.5, urea (CO(NH 2 ) 2 ) 3. Deionized water (H 2 O) 100.

Abstract

The invention discloses a metal organic framework fertilizer and a preparation method thereof. The novel fertilizer is prepared from a nutrient molecule and an outer framework thereof. The metal organic framework fertilizer is characterized in that the outer framework is prepared from an inorganic metal ion cluster and an organic joint under a hydrothermal condition through coordination. The metalorganic framework material is divided into a metal organic framework material containing zinc and a metal organic framework material not containing zinc. Hydrothermal synthesis conditions for the novel metal organic framework material fertilizer are as follows: the reaction temperature is 100 DEG C, reaction time is 24 hours, the heat-up rate of a reaction kettle is 2 DEG C / min, and rotation speed of a stirrer is 120 revolutions per minute. The novel fertilizer is prepared from the following nutrients: a compound I prepared from 4-5% of N and 16-20% of P, and a compound II prepared from 5-7%of N, 15-18% of P and 2-3% of Zn. According to a soil cultivation test, the novel metal organic framework material fertilizer has good nutrient controlled-release effect, and increases utilization rate of nutrients.

Description

technical field [0001] The invention belongs to the technical field of fertilizer manufacture, and specifically designs a metal-organic framework material-based novel fertilizer and a preparation method of the metal-organic framework material-based fertilizer. Background technique [0002] As we all know, chemical fertilizers play an important role in agricultural production. According to statistics from the Food and Agriculture Organization of the United Nations (FAO), fertilizers play a 40-60% role in increasing food production [1] , the current global population is about 7 billion and is expected to reach 9.5 billion by 2050 [2] At that time, the demand for food will be twice what it is now. It is foreseeable that chemical fertilizers will become more prominent in the next few decades, and the amount of input will also increase significantly [3] . However, the problem of unreasonable fertilization is still prominent, resulting in low fertilizer utilization rate, whic...
