example 1

[0023] Weigh calcium zeolite 770kg, quick lime 200kg, phospholipidized starch mixture 30kg;

[0024] Grind all the above-mentioned raw materials to 100-200 mesh in advance, then put them into the mixer, mix them evenly, and get the paddy field water sedimentation and fertilizer fixation agent after packaging;

[0025] According to the use amount of 100 kg per mu, in a paddy field of 0.5 mu, the field water can be clarified within 20 minutes.

example 2

[0027] Take by weighing vermiculite 665kg, unslaked lime 300kg, phospholipidized starch mixture 35kg;

[0028] Grind all the above-mentioned raw materials to 100-200 mesh in advance, then put them into the mixer, mix them evenly, and get the paddy field water sedimentation and fertilizer fixation agent after packaging;

[0029] According to the consumption of 150 kg per mu, the water in the paddy field of 0.5 mu can be clarified within 15 minutes.

example 3

[0031] Weigh montmorillonite 740kg, quicklime 240kg, phospholipidized starch mixture 20kg;

[0032] Grind all the above-mentioned raw materials to 100-200 mesh in advance, then put them into the mixer, mix them evenly, and get the paddy field water sedimentation and fertilizer fixation agent after packaging;

[0033] The above-mentioned components are used in 0.5 mu of paddy fields according to the amount of 50 kilograms per mu, and the field water is gradually clarified in 30 minutes.

[0034] By probation, when the rice ear is mature and harvested, the rice grains are full, and the ear length (cannot be measured because of the unified harvest of the harvester) is observed in use, and embodiment one is the best formula.

Abstract

The invention provides a rice field water settling and fertilizer fixing agent and relates to the technical field of sewage treatment.The rice field water settling and fertilizer fixing agent is composed of 650-750 parts of a base material, 200-350 parts of quick lime and 20-35 parts of a phospholipid starch mixture.The rice field water settling and fertilizer fixing agent and a preparation method thereof have the advantages that mineral rich in minerals is adopted as the main raw material, harmful substances in pesticide are converted into harmless substances, toxicity of pesticide is relieved, leaked trace elements caused by long-term utilization of chemical fertilizer in the agricultural cultivation process can be supplemented, toxicity in soil can also be supplemented, and a connection function is achieved for recovering soil aggregate.By means of the rice field water settling and fertilizer fixing agent and the preparation method thereof, the technology is simple and easy to operate, and a significant role is played in improving rice field water loss pollution and protecting the ecological environment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a paddy field water sedimentation fertilizer fixer and a preparation method thereof. Background technique [0002] In recent decades, a large amount of chemical fertilizers and pesticides have been used in agricultural cultivation. When it rains, the denitrification ground flows into the water body along with the rainwater, causing water pollution, especially in paddy fields. The rice planted in agriculture has changed from the original rice seedling transplanting to sowing, sowing rice fields At the end of the wheat harvest, the rice seeds are directly sown into the field. The nitrogen and phosphorus fertilizers used as base fertilizers are replaced by surface fertilizers. Pesticide control, harmful substances in pesticides and residues of heavy metals such as arsenic, cadmium, and cyanide in some pesticides are also mixed with fertilizers, mixed in field water, and fer...
