preparation example Construction

[0048] The preparation method of the present invention will be described in further detail below with reference to specific examples. It should be understood that the following examples are only for illustrating and explaining the present invention, and should not be construed as limiting the protection scope of the present invention. All technologies implemented based on the above content of the present invention are covered within the intended protection scope of the present invention.

[0049] The experimental methods used in the following examples are conventional methods unless otherwise specified; the reagents, materials, etc. used in the following examples can be obtained from commercial sources unless otherwise specified.

Embodiment 1

[0051] refer to figure 1 Shown process steps: add 5g urea, 5g calcium hydrogen phosphate, and 5g zein into the ball mill (material mass ratio is 1:1:1), set the ball mill parameters, namely the ball mill rotating speed 400r / min, Mechanical reaction time 30min. The slow / controlled release fertilizer is prepared, and the slow / controlled release fertilizer contains nitrogen, phosphorus and calcium required by plants.

Embodiment 2

[0053] refer to figure 1 Shown process steps: add 8g urea, 8g calcium hydrogen phosphate, and 4g zein into the ball mill (material mass ratio is 2:2:1), set the ball mill parameters, namely the ball mill rotating speed 400r / min, Mechanical reaction time 30min. The slow / controlled release fertilizer is prepared, and the slow / controlled release fertilizer contains nitrogen, phosphorus and calcium required by plants.

[0054] figure 2 A is the scanning electron microscope image of unground zein, figure 2 The B in the zein is the scanning electron microscope image of the ground zein. It can be seen from these two images that the macroscopic structure of the gliadin has not changed, and the shape is still the same as the previous bowl. The secondary structure has not changed, it is still a protein, and it does not cause other side effects to the crop.

Abstract

The invention provides a slow / controlled release fertilizer prepared based on natural protein and its preparation method and application. The slow / controlled release fertilizer has the function of improving the disease resistance of fertilized crops and improving the quality of fertilized crops; Amino acids can stimulate and regulate the rapid growth of plants, prevent and control plant diseases, promote the growth of plants and promote the absorption of nutrients; enhance the metabolic function of plants, improve photosynthesis, promote the development of plant roots, and accelerate plant growth and reproduction; realize slow / controlled release Fertilizer, improve the utilization rate of chemical fertilizer.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a slow / controlled-release fertilizer prepared based on natural protein and a preparation method and application thereof. Background technique [0002] Chemical fertilizers play a very important role in promoting food production and agricultural production. China is a big agricultural country, and agriculture is the foundation of our country. To produce food with limited arable land, we must ensure high crop yields. Therefore, my country's agricultural production is inseparable from the use of chemical fertilizers. During the growth of crops, the use of fertilizers can provide them with the nutrients they need to increase crop yields. However, ordinary fertilizers are easily lost in soil, water and air without being effectively used by plants, which will cause soil compaction or desertification, water pollution and environmental degradation. Therefore, it is ve...
