(I) Direct application method: The carbon dioxide gas is compressed into a steel bottle and can be directly applied in the protection zone using a plastic pipe. Generally, two parallel ventilation pipes are set in the protected area, about 80 centimeters from the ground, 10-20 centimeters away from the top of the shed, and a hole with a diameter of 0.3 centimeters is drilled every 60 centimeters on the pipe. It is 8 o'clock on sunny days. Relieving air once every 30 minutes to 11:30, and adding about 2 kg of carbon dioxide for 1 hour, the carbon dioxide concentration in the greenhouse can reach 1200-1500 ppm. This method is convenient, low labor intensity but high cost.
(b) Chemical reaction method: Generally, dilute sulfuric acid and ammonium bicarbonate are used to produce carbon dioxide gas in production. The specific approach is: take 10-20 points per acre, dig at each point 30 cm in diameter, depth of 20 cm in the earth pit, can also be abandoned plastic bottles or bowls, etc. hanging in the protected area in mid-air, due to carbon dioxide ratio The air is heavy and the plastic containers are more than 1 meter away from the ground. In order to prevent the reaction of the ammonium bicarbonate from being violent, the foam splashes, and the operator and the stems and leaves of the celery should be injured. A certain amount of fresh water should be injected into the container first, and then the quantitative sulfuric acid should be gradually added to the clean water to continuously stir the water. , can be formulated once in 3 days. The amount of sulfuric acid released per point may depend on the control area. Ammonium bicarbonate is added half an hour after sunrise every day, and stirring is continued. Then, the protected area is sealed for about two hours and then released. From the start of easing seedlings, they can be placed continuously for 40-60 days (parking on rainy days). Once a 1-2 kilograms of carbon dioxide is added to the conservation area once per acre, the production can be significantly increased, and its concentration in sunny days does not exceed 1500 ppm. Due to the unequal area of ​​protected areas, the amount of sulfuric acid and ammonium bicarbonate used each time is different. Their amount can be calculated as follows: Daily amount of ammonium bicarbonate required (grams): Volume of protected space (cubic meters) Applied carbon dioxide concentration (ppm) 0.0036 (1 ppm of carbon dioxide per cubic meter of ammonium bicarbonate required Grams); The required amount of hydrophobic acid per day (grams) = the amount of ammonium bicarbonate needed per day (grams) 0.62 [1 grams of ammonium bicarbonate requires 0.62 grams of sulfuric acid (specific gravity 1.84) to react].
Green Tea is unleavened tea that is not made by fermentation. Because of the different processing method, tea have two kinds shape named Gunpowder Tea and chunmee tea, gunpowder is round shape likes pearl and chunmee is strip shape likes eyebrow. Green tea retains more natual substances of fresh leaves and contains more nutrients such as tea polyhenols, catechins, chlorophyll, caffeine, amino acids and vitamins. These natural nutrients has many function such as:
1. Anti – aging effects;
2. Disease suppression;
3. Preventive and anticancer properties;
4. Radiation protection;
5. Resisting virus bacteria;
6. Beauty & Skincare effect;
7. Refresh the mind;
8. Effect of diuresis;
9. Relieve fatigue;
10. Protecting teeth and improving eyesight;
11. Eliminate bad breath;
12. Reduce high blood pressure, high blood lipids, high blood sugar;
13. Reducing fat and promoting digestion;
14. Visceral fat suppression;
And so on.
