Embodiment 1

[0018] The liquid carbon dioxide is polymerized into carbon dioxide snowflake dry ice through a polymerizer, and the carbon dioxide snowflake dry ice, calcium carbide powder, and distiller's grains are stirred evenly by a mixer in a weight ratio of 2:1:0.2, and then sent to a granulator to obtain a granular fertilizer; The fertilizer is put into the bucket of the fertilizer applicator, and then the granular fertilizer is evenly sprayed into the soil between vegetables through the spray gun by the air pressure of the air compressor, and the injection volume is 60 kg / mu.

Embodiment 2

[0020] The liquid carbon dioxide is polymerized into carbon dioxide snowflake dry ice through a polymerizer, and the carbon dioxide snowflake dry ice, calcium carbide powder, and distiller's grains are stirred evenly by a mixer in a weight ratio of 4:1:0.5, and then sent to a granulator to obtain a granular fertilizer; The fertilizer is put into the bucket of the fertilizer applicator, and then the granular fertilizer is evenly sprayed into the soil between the vegetables through the spray gun by the air pressure of the air compressor, and the injection volume is 40 kg / mu.

Abstract

The invention discloses a method for preparation of particle fertilizer for pollution-free vegetables and the method for use, which contains: polymerizing liquid carbon dioxide into carbon dioxide snow with a polymerizer, stirring uniformly the mixture of carbon dioxide snow, carbide powder and lees by weight ratio of (2-4): 1: (0.2-0.5) by a stirrer and sending into pelletizer to prepare particle fertilizer; putting the particle fertilizer into a bucket of a fertilizer applicator, spraying into the space earth of the vegetable by the gas pressure of air compressor, the spraying usage being 40-60kilogram / unit of area. The invention is characterized in that the method for preparation is simple, it is convenient to operate, and it is highly effective and nontoxic.

Description

technical field [0001] The invention relates to an agricultural chemical fertilizer, in particular to the preparation and application method of granular chemical fertilizer for pollution-free vegetables. Background technique [0002] With the continuous improvement of people's living standards, urban and rural residents' demand for edible vegetables, especially pollution-free vegetables, is increasing day by day, resulting in the continuous development and expansion of the production and planting scale of pollution-free vegetables. The traditional way of controlling insect pests in vegetables is to use pesticides. Usually, the pesticides are diluted with water and poured into the spraying machine, and then manually sprayed on the farmland. It causes pesticide poisoning and other hazards, and also pollutes the soil, and it is impossible to apply fertilizers to control insects in high temperature and rainy days. [0003] The content of carbon dioxide in the air is 0.03-0.04%....
