How to plant cucumbers in deep winter greenhouses Before planting, spread over 6,000 kg of high-quality soil miscellaneous fertilizer per acre, preferably cow manure, pig manure, chicken manure compost, deep-turn 40 cm, break up clods, make feces and soil Blend evenly. After flattening the ground, a person is bowed in the front corner of the greenhouse. On the north side walkway, a person takes a wooden stick or a bamboo pole with 50 cm and 70 cm marks, and then plays with a string on the side. Line, then press 50 cm, 70 cm alternating line. After hitting the line, use the rake to open the ditch from the south to the north to form a 50 cm small row and a 70 cm wide row. In the ditch, planting seedlings were planted at a plant spacing of 25-27 cm; the distance between the south plants was appropriately reduced and the plant spacing at the north increased. One day before cutting, the seedlings were flooded with water in the seedbed to ensure that they were not cut off. Remove containers from container nursery. When the seedlings are planted, they must undergo strict selection, removing weak seedlings, aging seedlings, and injured seedlings, and selecting uniform seedlings of the same size to be planted. The depth of planting seedlings should be less than 1 cm above the ridge surface of the ridge seedlings. Because the seedlings can't be watered, they should use the earthworms to ditch the soil between the rows to form a ditch on both sides of the planting ditch, and then fill the planting water. Each seedling is watered with L5 kg. After the water seeps, the earth ridges can be taken from the rows with a trench. After cultivating the ridges, use a small wooden board with a length of 25 to 30 centimeters to flatten the ridges, and then cover 90 to 100 centimeters of mulch on two ridges of 50 centimeters. The way to cover the film is to put two square stools upside down on the north sidewalk. The legs of the stool are up and the plastic film is tied on the stool legs. Two people pull up the plastic film to the front bottom corner to bury the south end of the plastic film in the soil. Reach the aisle with a razor blade, and then use a blade to open a longitudinal hole in the position of each cucumber. Take the cucumber seedlings out of the membrane and place the membrane in the mouth. In order to increase the ground temperature, it is sometimes not only to cover the mulch between 50 cm rows, but also to cover the 70 cm large rows of mulches, which is beneficial to reducing the air humidity and increasing the temperature. The disadvantage is that due to comprehensive coverage, the carbon dioxide produced by the decomposition of organic matter by soil microorganisms cannot be fully released into the space. In order to increase the fertilizer efficiency of basal fertilizer, 50 kg of diammonium phosphate per acre is applied before the watering, which is applied between the cucumber seedlings.
