Embodiment 1

[0051] Carry out the preparation of novel environmentally friendly medicinal fertilizer in the following ways:

[0052] S1 Preparation of kaolin protein composite slow-release adhesive

[0053] S1-1 Add 0.1mol / L NaOH aqueous solution to the water-soluble feather keratin powder until it is completely dissolved, then add deionized water to dilute to obtain a feather keratin hydrolyzate with a feather keratin content of 1mg / L. Dissolving hydroxypropyl methylcellulose with deionized water into a hydroxypropyl methylcellulose aqueous solution with a hydroxypropyl methylcellulose content of 1mg / L, according to the volume ratio of 9:1, the hydrolyzate of feather keratin and The aqueous solution of hydroxypropyl methylcellulose is mixed, and the pH value is adjusted to 8 with an aqueous NaOH solution to obtain an aqueous solution containing a natural polymer protein complex.

[0054] S1-2 According to the weight ratio of kaolin, guar gum and natural high-molecular protein complex is ...

Embodiment 2

[0063] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment:

[0064] In S1-1, the hydrolyzate of feather keratin is mixed with the aqueous solution of hydroxypropyl methylcellulose according to the volume ratio of 6:4.

[0065] The weight ratio of kaolin, guar gum and natural polymer protein complex in S1-2 is 1:0.5:0.8.

[0066] In parts by weight, the composition of the medicinal fertilizer is 80 parts of macronutrient fertilizer, 5 parts of medium and trace element fertilizer, 10 parts of monosultap, 2 parts of chlorantraniliprole and 20 parts of kaolin natural polymer slow-release adhesive.

[0067] Among them, the fourth slow-release layer contains 64 parts of macronutrient fertilizer and 12.5 parts of kaolin protein composite slow-release adhesive, and the third slow-release layer contains 5 parts of monosultap, 2 parts of chlorantraniliprole and 2 parts of kaolin Natural polymer slow-release adhesive, the second slow-release...

Embodiment 3

[0069] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment:

[0070] In S1-1, the hydrolyzate of feather keratin is mixed with the aqueous solution of hydroxypropyl methylcellulose according to the volume ratio of 8:2.

[0071] The weight ratio of kaolin, guar gum and natural polymer protein complex in S1-2 is 1:0.3:0.6.

[0072] In parts by weight, the composition of the medicinal fertilizer is 60 parts of macronutrient fertilizer, 3 parts of medium and trace element fertilizer, 6 parts of monosultap, 1.5 parts of chlorantraniliprole and 15 parts of kaolin natural polymer slow-release adhesive.

[0073] Among them, the fourth slow-release layer contains 45 parts of macronutrient fertilizer and 8 parts of kaolin protein composite slow-release adhesive, and the third slow-release layer contains 2 parts of monosultap, 1.5 parts of chlorantraniliprole and 1.5 parts of kaolin Natural polymer slow-release adhesive, the second slow-relea...

Abstract

The invention belongs to the technical field of agriculture, and relates to a novel environment-friendly medical fertilizer which comprises the following components in parts by weight: 50-80 parts of a macroelement fertilizer, 0.1-5 parts of a medium trace element fertilizer, 1-10 parts of monosultap, 0.1-5 parts of chlorantraniliprole and 10-20 parts of a kaolin natural polymer slow-release adhesive. The preparation method comprises the following steps: respectively crushing a macroelement fertilizer, a medium trace element fertilizer, monosultap and chlorantraniliprole according to set weight parts, and preparing a kaolin protein composite slow-release adhesive according to set weight parts; the fourth slow-release layer, the third slow-release layer, the second slow-release layer and the first slow-release layer are sequentially wrapped and dried to prepare a pesticide fertilizer finished product. The invention further provides application of the novel environment-friendly pesticide fertilizer in rice pest control. The kaolin natural polymer slow-release adhesive is used as the adhesive, so that the action time of the medical fertilizer can be prolonged, the utilization rate of the medical fertilizer is increased, and degradable natural components are adopted, so that the requirement of environmental friendliness is met.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a fertilizer for planting crops, in particular to a novel environment-friendly medicinal fertilizer and its preparation method and application. Background technique [0002] my country is a large grain and agricultural production country in the world. With the continuous acceleration of urbanization and industrialization, agricultural production is facing a shortage of labor. Although professional organizations such as aerial defense and contracted prevention and control have emerged in China, which have improved some problems in the agricultural production process, for areas with small areas and many mountains, areas that are not suitable for mechanized operations, the contradictions in agricultural production are still prominent, and phenomena such as abandonment appear . [0003] Medicinal fertilizer is a new type of ecological compound fertilizer formed by mixing pesticides...
