In early July, the open-air cucumber planting period is in progress. Here we will introduce several points for the cultivation of open-air cucumbers for reference by farmers. Cucumber in open air is mostly broadcasted on the open, and double ditch is opened on small stilts with a ditch of 40 cm and a ditch depth of 3-4 cm. Poor soil moisture can be watered and run ditch, ensure that the next plant, according to the distance of 20-25cm dry seeds seeded, 2-3 seeds per hole, 1.5cm after sowing after sowing, do not seal groove at this time. Generally, 4-5 days after sowing, the seedlings will be seedlings, 1-2 true leaf seedlings will be seedlings, weak seedlings, diseased seedlings and abnormal seedlings will emerge. When 4-5 true leaves are selected, a strong seedling is selected and the seedlings are planted at a spacing of 20-25 cm. About 4000 strains per mu. Fill the ditch after the seedlings are set. When the cucumbers start to pull vines, they are put into racks, and they use a bamboo or bamboo shoot more than 2 meters long to form a "herringbone" shaped flower stand. When pruning, keep the main vine, when the top of the roof. The side branch, old leaves, diseased leaves and tendrils below 50 cm in the main vine are all removed to facilitate ventilation, light transmission and nutrition enhancement. Other collaterals can retain 1-2 leaves after the female flower. At the same time, the vines should be tied in time, and about 50 cm of vines should be tied once. Before the cucumber is covered with cucumbers, due to more rain, the soil is easily stained by water, affecting the development of the root system, and we should pay attention to cultivating and weeding. The cultivator depth should not be too deep. Generally, the first cultivator is 3-5cm, the second cultivator is 5-10cm, and the cultivator stops cultivating. Pay attention to the discharge of stagnant water immediately after the rain. Cucumber is a kind of vegetables that require more water. Therefore, the management of water and fertilizer should follow the principle of “watering a small amount of ground water, chasing a ground and chasing less chaseâ€. After the seedlings with watering topdressing Miao Fei, generally 4-5 kg ​​of urea per acre topdressing. Pumping vines, flowering results of re-application of phosphorus and potassium fertilizer, with water per acre topdressing phosphorus and potassium fertilizer 20-25 kg. The melon rushes to apply about 25 kilograms of potassium sulfate compound fertilizer in the middle of Hubei, and collects 1 time to recover 1 fat. At the same time, the 0.2% potassium dihydrogen phosphate and 0.1% zinc sulfate were sprayed with the spraying leaf every 7-10 days to increase the disease resistance of the plants. Pests are the focus of open-air cucumber control. Plutella xylostella, Pieris rapae, Spodoptera exigua, etc. can be controlled with a dimensional salt; aphids and whiteflies can be treated with imidacloprid plus acetamiprid.
