Plants are in a state of "quasi-starvation" with a C2 concentration(cheap plastic plant pots wholesale price lithuania). As the light weakens and the night arrives, plant respiration dominates, and the COQ concentration continues to rise. Different sheds and management are different, and the peak level of CO2 concentration is different(plastic planter manufacturers). Only the one-time investment is high, and the requirements for absorption and filtration devices are strict.

For example, the average particle diameter is about 1 cm, and CO2 can be slowly released when applied to the soil(fabric bag manufacturer). In practice, in the process of greenhouse vegetable production in China, it usually starts at sunrise or 0.5 ~ 1 hour after sunrise and ends before ventilation. Increase the application of organic fertilizer, increase the soil organic matter, and cultivate vegetables in the facility(cheap plastic plant pots wholesale price lithuania).
I don’t understand some long-acting and slow-release C2 gas supplement ways(nursery supplies pots), and I don’t know how to use the microorganisms in the soil to decompose organic matter, which not only decomposes and releases CO(cheap plastic plant pots wholesale price lithuania)? gas, but also plays the role of potassium release, nitrogen fixation, and phosphorus release for plants to absorb in a long-term and balanced manner. use(plastic plant pots cape town).
Coq resources were discovered in Foshan, Guangdong and Taixing, Jiangsu in the 1970s and 1980s respectively, with purity of 99.6% and 98.75%, but they have not been well developed and applied(plastic garden plant pots). Fuel combustion will further transform coal-fired stoves, add gas purification devices, and input them into the facilities after removing harmful components such as No., S2 and Co(cheap plastic plant pots wholesale price lithuania).
Special attention should be paid to the water management of greenhouse vegetable production: water should be controlled during the seedling stage to promote root growth, and small water should be frequently poured in the middle and late stages to increase yield(polystyrene plant trays). CO2 fertilization in the facility, in addition to enhancing ventilation, artificially supplemented CO2 fertilizer sources mainly include the following five types(cheap plastic plant pots wholesale price lithuania).
The CO2 fertilization concentration in the facility is usually 800~1500 microliters as the recommended fertilization concentration for most crops(20 gallon grow bags). Or the amount of nitrogen fertilizer and human feces and urine applied at one time is too large, which often causes crops to be damaged by ammonia(cheap plastic plant pots wholesale price lithuania). During most of the time between 3:00 and 15:00, the CO2 concentration is very low, only about 200 microliters/liter.
In order to promote the uniform distribution of temperature and CQ in the greenhouse(cell flats), and alleviate the low concentration of CO2 and high relative humidity of the plant population, it is necessary to promote the air flow in the facility to achieve high-quality and high-yield vegetable production in the greenhouse(cheap plastic plant pots wholesale price lithuania). According to the measurement, the CO2 concentration can be as high as about 800 microliters/liter(heavy duty nursery pots).
Therefore, to make up for the C2 deficit in the facility, it is generally possible to increase production by 20% to 30% and improve quality(cheap plastic plant pots wholesale price lithuania).During the production process of the facility, the CO2 gas concentration changes in the facility are not understood, the Ca fertilization technology in the facility is not well mastered, the management is rough, and the expected results cannot be achieved or cause harm(seed starting pots).
CO2 fertilization in facilities is an important management measure in facility cultivation(cheap plastic plant pots wholesale price lithuania). According to measurements, the diurnal changes of COQ concentration in the shed under the airtight conditions in winter and spring show a typical "single-valley" change, that is, as the sun comes out during the day(fabric bags wholesale), plant photosynthesis continuously consumes C2, and the CO2 concentration drops sharply at 10 in the morning.
The suitable concentration range is 600 to 900 microliters/liter(nursery bags suppliers). The CO2 fertilization time in the facility. In theory, the CO2 fertilization in the facility should be carried out during the period when the photosynthesis is most vigorous in the life of the crop and the time when the light conditions are the best in a day(cheap plastic plant pots wholesale price lithuania). In addition, the furnace or lamp with biogas and alcohol as fuel can also be used for CO2 fertilization.(grow pots for sale)
The device uses coke, charcoal, briquette and coal as fuel, and has a good development prospect in rural areas(cheap plastic plant pots wholesale price lithuania). The simple fertilization method is to place plastic buckets at different points in the greenhouse and manually put sulfuric acid and ammonium bicarbonate to produce C2, which is inconvenient to operate and poor controllability(nursery grow bags). Under relatively airtight conditions, the airflow speed in the greenhouse is low.
There are two sources of liquid C2: brewing industry, fertilizer industry by-products; ground storage 0Q(plug trays canada). Under the conditions of vegetable cultivation in the shed, the gas environment in the facility, from the content point of view, mainly includes three aspects: water vapor in the air, CO2 and harmful gases (please refer to Question 68)(propagation trays australia). Below the C concentration compensation point, the plant has no dry matter accumulation(cheap plastic plant pots wholesale price lithuania).
C2 granular gas fertilizer, such as CO2 granular fertilizer developed by Shandong Academy of Agricultural Sciences, is processed with CaCO as raw material, inorganic acid carrier and industrial conditioner according to scientific ratio(grow bags manufacturers). Liquid CO2 has high purity, safe and convenient use, but it has high cost and inconvenient ventilation(cheap plastic plant pots wholesale price lithuania). It is reported that 40 ~ 50kg is applied every 667m for about 40 days.
A variety of complete sets of CO2 fertilization devices have been developed in Shandong(plastic ground cover for weeds), Liaoning and other places to realize the sub packaging of sulfuric acid and ammonium bicarbonate, the gas production can be controlled, and the application effect in production is good(cheap plastic plant pots wholesale price lithuania). The CO2 release rate of this granular fertilizer is significantly affected by temperature and humidity, and the storage conditions are strict(greenhouse plant pots).
8 kg per 667 m2 per day can ensure the environmental CO2 concentration of about 1000 μ L / L(heavy duty plastic plant pots). Due to the limited source of sulfuric acid, the cost of this method is relatively high(nursery tree pots). Chemical reaction uses sulfuric acid ammonium carbonate reaction for C2 fertilization, which is the most widely used form in production at present(cheap plastic plant pots wholesale price lithuania). The chicken manure applied in the production of greenhouse vegetables is not rotten.
Sometimes improper operation will produce harmful gases and harm crops(cheap plastic plant pots wholesale price lithuania). The application of human manure and urine shall not exceed 500 kg every 667 meters, the application of cow manure and chicken manure as base fertilizer shall not exceed 3000 kg, and the application of topdressing shall be 300 kg(decorative plastic planters). The requirement is breeze conditions, the wind speed is 0.5~1m/s, and it is realized by ventilation, circulation fan, etc.
Because there is a great contact surface between plant roots and soil, there is frequent material exchange between soil and plants, which strongly affects each other(plastic plant pots ireland). Therefore, soil is an important ecological factor of plants. The growth and yield of plants can be affected by controlling soil factors(cheap plastic plant pots wholesale price lithuania). The ability of soil to meet the requirements of plants for water, fertilizer, gas and heat in time is called soil fertility(10x20 growing trays).
