Qiuchan Pepper Field Management Technology

1, good water management. During the transplanting to the mild seedling stage, water is poured 2-3 times in order to ensure timely seedling growth. In the door pepper, sit on the pepper fruit and grow to 3--5 centimeters, the water and fertilizer attack, promote the fruit. After easing the seedlings to sit before the fruit is stable, generally no drought or irrigated, so as to ensure the stable growth of the seedling period, prevent prosperous growth, and reduce flowering and fruit loss. In November, the weather became cold and watering was controlled to prevent the humidity from being bad and the fruit was rotten. 2, timely fertilizer. In the door pepper, sit tight on the pepper and grow to 3-5 cm, timely fertilizer, combined with watering 3-5 times. The top dressing is buried at a depth of 7-10 cm to maximize the utilization rate. Later, 0.2% urea and potassium dihydrogen phosphate can be used for foliar dressing. 3, timely pruning. The first pruning was performed before and after the budding of the budding pepper, and all the germinations of the following peppers were knocked out. In the middle and late October, the second pruning was carried out, and the upper terminal buds and ineffective buds were destroyed, prompting nutrient concentration to supply fruit growth. 4, cultivator, earth, weeding. After easing the seedlings, the first cultivator weeding was performed. After each watering, it should be cultivated once to prevent soil compaction and promote new root development. When the door pepper, sit tight on the pepper, can be combined with fertilizer down the earth, to prevent late lodging. 5, strengthen the management of greenhouses. From early August to early September, the stage of releasing dampness and cooling is released. During this period, the outside temperature is higher than 40°C, and the light intensity is between 8-10 million luxes, with heavy rain. At this time, the greenhouse management should be released around the wind. The shed film should be lifted by 70 centimeters. The two plastic cloths should be covered with bamboo. In case of heavy rain, the two sides of the film should be put down in time and the drainage should be protected against stains. From mid-September to mid-October, during this period, the outside temperature is gradually reduced to a suitable temperature for the growth of peppers, and the average daily temperature is about 20 degrees Celsius, and the light intensity is decreased and the rainwater is reduced. The film can be peeled off and the peppers can grow under natural conditions. From mid-October to early November, it is a heat preservation phase. During this period, the outside temperature was gradually reduced to a daily average temperature of around 10°C with frost. On both sides of the greenhouse, a 1m high cold-proof skirt film should be added. During the day, the greenhouse film should be lifted above the cold-proof skirt film to form an air outlet (band), kept at a temperature of about 25°C, and put down at night to seal the greenhouse. In case of cold current, the interior is covered with a thin film. Anti-frost, keep warm at 7-13°C. From the first half of November to the first month of January, it will be the anti-freezing and fresh-keeping stage. During this period, the average daily temperature is around 5°C, and the extreme low temperature is about 10°C. At this time, the temperature of the greenhouse is maintained at about 20°C during the day and at night above 5°C. The greenhouse must be tightly closed and compacted. Only a small air outlet is left at both ends, a small bow shed is placed in the shed, and a small bow shed is covered with haystacks. The small bow film and cover were uncovered on sunny days and covered at night. Can also be inserted between the small bower and the greenhouse film wheat straw barley, thickness of 5-10 cm, a little higher than the height of pepper, can play a role in antifreeze preservation. When the cold weather came, a layer of wheat straw was placed on the small bow film. China Agricultural Network Editor
