[0021] Take ammonium bicarbonate (A), potassium dihydrogen phosphate (B), potassium hydrogen phosphate (C) and water for later use.

[0022] 1. Take 25 parts of A, 60 parts of B, and 15 parts of C, and mix them evenly.

[0023] 2. Take 45 parts of A, 50 parts of B, and 5 parts of C, and mix them evenly.

[0024] 3. Take 40 parts of A, 40 parts of B, and 20 parts of C, and mix them evenly.

[0025] 4. Take 30 parts of A, 55 parts of B, and 15 parts of C, and mix them evenly.

[0026] 5. Take 40 parts of A, 45 parts of B, and 15 parts of C, and mix them evenly.

[0027] 6. Take 35 parts of A, 50 parts of B, and 15 parts of C, and mix them evenly.

[0028] 7. When applying, put any product in examples 1 to 6 into a simple open container in the protected area (such as a basin, a barrel or a pit, a cave, etc.) with an impermeable plastic film, in a weight ratio of 1: 5 Just add water.

Abstract

This invention discloses a CO2 gaseous fertilizer, which can provide CO2 with a certain concentration to crops in greenhouses. The CO2 gaseous fertilizer is obtained by uniformly mixing ammonium bicarbonate 25-45%, potassium dihydrogen phosphate 40-60%, and dipotassium hydrogen phosphate 5-15%. When used, the CO2 gaseous fertilizer is added into an open container in protection soil, and then diluted with water. CO2 is rapidly released in the early stage, and slowly and stably released in the later stage to keep the CO2 concentration at 800-1200 ppm. The CO2 gaseous fertilizer has such advantages as abundant raw materials, simple preparation process, and convenient usage, and can increase the productivity by 15-20%, and shorten the mature period by 3-7 days.

Description

1. Technical field [0001] The present invention relates to a chemical fertilizer, in particular to a gas fertilizer, to be precise, a protective carbon dioxide gas fertilizer. 2. Background technology [0002] 45% of the dry matter of plants is carbon, the source of which is CO in the air 2 , it takes 1.6g CO to synthesize 1g dry matter 2 . Optimum CO for plant growth 2 The concentration range is about 1000ppm. When the concentration is not higher than the saturation concentration, the rate of photosynthesis and CO 2 Concentrations are positively correlated. while atmospheric CO 2 The concentration is only about 300ppm. In high-density cultivation greenhouses, CO 2 The concentration will even drop below 100ppm, which will seriously affect the progress of photosynthesis, resulting in slow plant growth, severe flower and fruit drop, many deformed fruits, low yield and poor quality. But CO 2 When the concentration is higher than the plant saturation concentration, the s...
