Problems solved by technology

However, the photosynthetic CO of solanaceous fruits and legume vegetables in protected areas 2 The saturation point is at 1000-1500ppm. From November to March, the vegetable greenhouses in protected areas cannot communicate with the outside world due to the flow of thermal insulation air, and the green vegetables in the greenhouses grow rapidly. CO 2 The consumption is large, and its concentration is less than 300ppm, which is less than 60% of the concentration required for normal growth of vegetables. CO2 in the shed 2 Insufficiency seriously affects its photosynthesis, and the yield is difficult to further increase
[0004] Combining the above methods, each has its advantages and disadvantages. The traditional method takes up a lot of space, wastes the limited space in the greenhouse, is unsanitary, and has an initial odor; in the chemical

Embodiment Construction

[0014] The full-burning coke carbon dioxide gas fat cake is made of the following raw materials in weight percentage, 50% of charcoal powder after carbonization of organic matter including sawdust, 30% of desulfurized coke powder, 3% of gelatinized pullulan, high 0.2% of chloric acid, 3.8% of kaolin, the above raw materials are evenly mixed, and then 13% of water is added to reconcile, put into a cake mold for extrusion, dehydration and air drying to obtain the finished product.

[0015] The role of each raw material, water is easy to process and shape; oxidant perchloric acid is combustion-supporting; carbonized charcoal powder and desulfurized coke powder are C sources; gelatinized starch is both a binder and a C source; kaolin is a dedusting agent. Carbonized charcoal powder comes from wood chips, plant straw chips, etc.

[0016] Production process: material selection and measurement-mixing-adding water to reconcile-putting into cake-type mold extrusion-dehydration and dryi...

Abstract

A fully combustible coke-CO2 cake for generating gas fertilizer used in the plastic film shed in the winter is prepared from charcoal powder, desulfurized coke powder, gelatinized branch-chain starch, perchloric acid and kaolinite through proportional mixing, adding water, stirring, die pressing and drying.

Description

technical field [0001] The invention belongs to the field of carbon dioxide gas fertilizer, and in particular relates to an all-combustion coke carbon dioxide gas fertilizer cake and a special burner thereof, which are used for agricultural production in winter protection facilities such as plastic greenhouses to supplement the lack of carbon dioxide in the greenhouse. Background technique [0002] Carbon is an important raw material for the formation of photosynthetic products. Atmospheric and soil respiration is the uptake of CO by crops 2 The main source of CO, while atmospheric CO 2 The content has a certain range, and the CO released by soil respiration 2 It is affected by factors such as soil organic matter content, soil temperature, and microbial community. Winter and early spring heat preservation is an important task in the production of facility agriculture, and the heat preservation process affects the CO inside and outside the greenhouse. 2 AC, CO in greenhou...
