The optimized method of the color pepper cultivation by the application of "CO2 slow release oxygen-enriched straw fermentation technology"
First, Get ready for greenhouse according to the "CO2 slow release oxygen-enriched straw fermentation technology".
Second, selection of species
Select highly yield, strong resistance, and strong adaptability of the color pepper species, such as the rubasse pepper, citrine pepper and so on.
Third, Cropping arrangements
To meet the demands of the market, the Plan of cropping arrangements should be scheduled. For example, planning sell the color pepper on Chinese New Year, it should breed in mid-August, transplant stock in early October. The age of seedlings should between 45～50 day.
Fourth, land preparation and fertilization (distribution of fertilizer types and amount according to production standards)
1, Base fertilizer
(1) Green criteria: new vegetable farmland, 35 kg of diammonium phosphate, 20 kg of urea, 40 kg of potassium sulfate, fowl manure fermentation 3-6 cubic meters; old vegetable land, superphosphate 50 kg per Chinese acre, fowl manure fermentation 3-6 cubic meters. (It’s not necessary to use the chemical fertilizers when the farmland has continuous cultivated vegetable for more than three years)
(2) Organic standards: each Chinese acre use FCMP 75 kg, fowl manure fermentation 6-9 cubic meters, bean 500 kilograms.
2, Land preparation: try to make the base fertilizer evenly and then make a deep ploughing.
Fifth, Field planting
1, Density: Row space is 0.65 to 0.75 meter, inter plant distance is 0.45 to 0.5 meter. It should plant crops between 2277 and 1776 each shed.
2, It should plant on high ridge, transplant stock along the ridge. Waters totally to make seedling steady after planting (Before the end of October watering in afternoon or in evening, while after the end of October watering in morning).
3, Second days seal with the soil, then drill hole between seedlings along the seedling line, insure the hole deep enough to pass though the fermentation layer, and the aperture should be about 2 centimeters.
Sixth, field management
1, Early management
Protect from high temperature with the shading net and the measure of ventilation.
Pest control, especially protect from aphids and red spider (use of insect-protect net, yellow plate, biological pesticides or chemical pesticides); anti-virus disease (control by biological, physical, chemical methods).
Lay film in proper time, it's not suitable lay the film immediately after planting in late September or early October, for the temperatures is so high that the too much water and the high temperature would cause the seedling to death. It's suggested laying the film in early November.
Pruning: remain the appropriate sprouts to promote root growth, which will help the medium-term fruit produce. It's time to wipe out the sprout when it is long as 0.18 to 0.20 meters. (Commonly known as Feng Zhang pruning). Generally do pruning two or three times.
Irrigate mainly with water, it can water with the leaching liquid of fermentation but fertilizer. After the watering day inspect whether the air holes between seedlings is clear, and drill holes as necessary.
Every 3-5 days spraying the leaching liquid of fermentation tank, mix with doubled or tripled water in accordance with the concentration of liquid.
Properly hoe tillage to increase soil permeability.
Supplement water to fermentation tank in time, generally seven days one time, and keep air supply fan running all day to supply carbon dioxide.
2, Medium-term management
The point is pruning, deblossoming and fruit thinning, that is, to maintain two or three branches and wipe off redundant buds promptly, carry out deblossoming and thinning of fruit timely. It is proposed that maintain 4-6 fruit per plant.
Timely watering, and supplement appropriate fertilizer in period of fruit expansion. Be careful not excessive, generally the quantity is a third of amount of conventional cultivation.
Control relative humidity of greenhouse, prevent from disease. And it is suggested that control the pest and virus disease by spraying leaching liquid timely or other biological control means.
Proper temperature management: 28 to 30 degrees Celsius during the day and not more than 35 degrees Celsius; 15 degrees Celsius during the night and not less than 10 degrees Celsius.
3, Fruitful-term management
Points: temperature management, keep more than 30 degrees Celsius during the day, while maintain more than 15 degrees Celsius at night. When it’s consecutive cloudy, in order to color the fruit and keep the normal growth of the next batch of buds and fruit, it is necessary to give artificial light.
Seventh timely harvest
When the fruit is colored completely, it is time to harvest. Prevent the fruit from dehydration and not lose marketability.
Eighth, the main technical parameters and economic parameters on application of "CO2 slow release straw oxygen-enriched fermentation technology"
The concentration of carbon dioxide can increased 4-6 times than conventional cultivation conditions, the temperature of soil 20 cm deep increased by 5 to 7 degrees Celsius after November, at the best raise more than 11 degrees Celsius; while the air temperatures increase 2 to 3 degrees Celsius (The data come from the greenhouse of Wang Wanzhao and Liu Baoyu, the farmer of Lige village, Miyun District Beijing China; technical operator Sun Hua, Wang WanZhao). On crops' performance: well developed root, stout stems, hypertrophy leaves, nice color, large flowers, increased waxy, thickening pulp, pure taste, good-shape color pepper, good marketability, few deformed fruit, and high commodity rate (assessment by Beijing Xiaotangshan special food supply base, technical director: Wang fudong, technical tracker: Li Junjie).
The yield of color pepper can increase more than 50 percent.
Ninth, Note: Any soil fungicide is prohibited.
