Cultivation and Management of Fruit Cucumber in Spring

Soil preparation, fertilization and planting fruit cucumber have a large amount of melon and need adequate nutrient supply. It is appropriate to choose loam with deep soil layer, high content of organic matter and water and fertilizer conservation. 5000 kg of rotten organic fertilizer is used every 667m2 before planting. At the same time, add 30kg superphosphate, 200kg cake fertilizer, 50kg plant ash, deep mixing, rake the border, make a 20-30cm high border, spread plastic film. If conditions permit, it is best to install drip irrigation facilities. It was planted in mid-February when the seedlings had 3-4 true leaves. When planting, dig a good hole according to the distance between the plants, plant the seedlings, bury a small amount of soil, and then irrigate the holes, waiting for underwater infiltration to seal the holes. Field management, temperature management. The greenhouse should be properly closed within one week after planting, and attention should be paid to keeping 25 ℃-30 ℃ in daytime, 18 ℃-20 ℃ at night, and no release more than 35 ℃ in order to promote seedling retardation. After slowing down the seedlings, it can be properly released to lower the temperature, generally keeping 22 ℃-25 ℃ in daytime and 16 ℃-18 ℃ at night. After entering the full fruiting stage, the temperature should be kept at 25 ℃-30 ℃ in the daytime and 15 ℃-17 ℃ at night. Fertilizer and water management. Slow seedling water should be irrigated 7 days after planting. After watering slow seedling water, root melon should be watered before sitting, generally not watered; root melon can be irrigated with small water every 3-5 days after sitting, do not flood irrigation, fertilize every other water with water once, apply compound fertilizer 10-15 kg every 667 square meters. Foliar fertilizer should also be applied 3-4 times during the growing period, generally spraying 0.2% potassium dihydrogen phosphate combined with trace elements. Plant adjustment. After planting, we should pay attention to remove the side branches from the rootstock and the side branches of the plant, generally pruning the single vine and removing the side vine. The female of fruit type cucumber is strong, and the node position of female flower is low. Generally, the female flowers produced by the first five nodes should be sparse, and melons should be retained from the sixth section to ensure yield. When the seedlings grow to more than 25 cm, the vines should be drawn in time to hang the vines, generally using silver-gray plastic rope to hang the vines. In the middle, 1-2 melons can be left in each section, and the extra female flowers can be thinned out. In general, no more than 2 melons can be left in each section, and the extra female flowers should be removed in time. In the middle and later stage of fruit cucumber growth, the lower leaves begin to age and lose the ability of photosynthesis, so the old and diseased leaves should be removed in time to improve ventilation and light transmission and reduce the occurrence of diseases and insect pests. The pest control of fruit cucumber is basically the same as that of ordinary cucumber, and the control methods are also the same. In the current production, the most serious diseases are Fusarium wilt, powdery mildew and downy mildew, and the main pests are aphids, beet armyworm and whitefly. The principle of prevention and comprehensive control should be followed in the prevention and control of diseases and insect pests. Timely harvest of female flowers in general open for 6-10 days, melon length 12-18 cm, horizontal diameter 2-2.5 cm can be harvested, harvest with scissors cut melon stalk, to prevent damage to seedlings, pay attention to handle gently.
