Cucumbers that are listed early in the Spring Festival are generally planted in sunlight greenhouses. Every 667m2 can be applied with 10 000 kilograms of high-quality rotten manure, deep plowing 30 centimeters. It can be said that 1 kilogram of fertilizer is 1 kilogram of melon. If the short-term cultivation or yield index is only about 5,000 kilograms, 5,000 to 6,000 kilograms of decomposed farmyard manure may be applied per 667 m2. Then we can make soil preparations and extend it to the north and south. The height of the sorghum is 60-65 cm wide, the width of the sulcus is 40-45 cm, and the height is 10-15 cm. We practice large and small rows of ribs with centimeters of ribs and 50 cm of row spacing. Planting from late November to early December. Before planting, open the ditch and lay the seedlings first at a spacing of 25 cm, 3 500 to 3 700 seedlings per 667 m 2 , diammonium phosphate can be applied between the plants, 5 to 6 g per plant, 230 to 40 kg per 667 m, After burying the seedlings in 1/3 of the height with a mortar, the water shall be poured to plant water and the water shall be sealed after the water seeps. Planting seedlings should not be too deep. After the burial, the small line covers the plastic film, and the large line spreads straw to reduce the air humidity. Finally, the greenhouse is insulated from cold and the ground temperature above 15°C is maintained. The temperature should be 30°C during the day and 20°C during the night. After the cucumbers start to grow slowly, the temperature can be controlled appropriately to reduce the temperature and raise the roots. Under normal circumstances, no watering is required, and the temperature difference between day and night should be increased. If the temperature exceeds 30°C, the window or quilting ventilation is required. After stopping at 20°C, the ventilation is stopped. 15 Put the grasshopper at °C and keep it at 15°C in the middle of the night and 12°C in the middle of the night. It should be maintained at 10～8°C before unwinding in the morning. After easing the seedlings, the vines must be inserted in a timely manner. The plastic vines should be the best for the cranes. The labor is convenient and the culvert can be set at any time when the faucet approaches the roof. Top dressing can be carried out 5~7 days before root melon harvesting. Fertilizers are mainly ammonium nitrate and diammonium phosphate. They can be applied alternately, each time being 10 to 15 kilograms, with the water under the mulching of small ridges under the plastic film. Cover with plastic film after irrigation. The full fruit period is the Minggou top dressing, and fully cooked chicken manure and fermented cake fat can also be used. Irrigation lasted for about 80 days and received 15 days of water. In the latter part of the result, it is a week of water. A total of about 15 irrigations of this cucumber are used. Irrigation should be performed on a sunny morning. Top dressing began from the beginning of the harvest, 20 days to 1 month, 10 days to half a month later, a total of 10 times. The cucumber has more severe weather and cannot normally be uncovered for several days in the case of continuous rainy days, so that the interior will not see the sunlight for a long time and suffer cold or even freezing damage. Special attention should be paid to cold insulation. When the outside temperature is not too low on cloudy days, it is necessary to fight for time, expel winds, and pay attention to water control. When the weather turns fine, it should pay attention to uncovering the straw curtain. If it cannot be lifted, the cucumber cannot adapt to the rapid increase in room temperature, often causing dehydration and wilting. Therefore, when the sunlight is strong at noon, the curtains should be shaded, and when the light turns weak, they will be exposed again. In the event of a sudden strong cooling of the cold air, emergency measures such as temporary fires or geothermal lines can be used to overcome the difficulties. The entire cucumber can not be topping, just drop the shelf treatment, a total of 2 to 3 times, each time before the fall can be destroyed by the old leaves, harvest root melon should be properly advanced in order to facilitate the growth of melons, increase production and quality.
