2. Cultivate strong seedlings; There are both imported varieties and domestic varieties of fruit cucumber seeds, but the prices are relatively expensive, so it is necessary to use precision sowing to raise seedlings at one time. Seedbeds can be made of horse manure or electric hotbeds. The seedling stage requires strict temperature, and the optimum temperature for germination is controlled at 24 ~ 28℃. After emergence, it is kept at 23 ~ 28℃ during the day and at 12 ~ 18℃ at night. Seedbed nutrient soil is made of decomposed horse manure, chicken manure, furnace ash, etc. , in line with the requirements of both relaxation and fertility.
3. Soil preparation and field planting; Fruit cucumber has high yield, large leaves and early fruiting period, but its root system is shallow and its fertilizer absorption ability is weak. Therefore, intensive cultivation is needed before planting, and it is best to improve the soil in greenhouse plots where vegetables are planted. The specific measures are as follows: applying livestock manure decomposed by biological bacteria to the 25cm topsoil in the shed, applying 4-5m3 per 667m2, 50kg of potassium sulfate, 30% of sand or furnace ash residue, etc. Then rotary tillage is used to till it is flat, so that the soil is loose and fertile, and watering does not harden, creating a soil environment conducive to the growth and development of roots.
4. Carry out wide and narrow row cultivation, with a width of 90 cm, a narrow row of 40-50 cm and a plant spacing of 25-28 cm. Irrigate root water immediately after planting.
5. Temperature management; After planting, measures such as multi-layer covering and heating can be taken to keep the temperature in the shed high, which is beneficial to slow down the seedlings. At the initial stage of planting, the daytime temperature is maintained at 28 ~ 32℃, the nighttime temperature is maintained at 16 ~ 18℃, and the temperature is lowered after slow sowing, and the daytime temperature is maintained at 25 ~ 30℃ and the nighttime temperature is maintained at 14 ~ 17℃. After flowering and fruiting, the temperature rose to 32 ~ 35℃ during the day and dropped to 12 ~ 16℃ at night.
6. Water management; After planting for 5-7 days, water the seedlings once when they are delayed, depending on the weather. Generally, it is better to water at 6-8 o'clock in the morning on sunny days (overheated cold water is harmful to roots at noon, and watering in the afternoon or at night will easily lead to high humidity in the shed and low soil temperature, leading to illness). No watering in rainy days.
7. Lighting and ventilation; Fruit cucumber has strong tolerance to low light, and can also obtain high yield under low light. When it is hot and bright in summer, use a sunshade net to cover it. In greenhouse management, the temperature and humidity in the greenhouse should be adjusted by ventilation, and the relative humidity should be controlled at 70% ~ 80% to prevent diseases caused by excessive humidity and the growth and development from being affected by excessive dryness.
8. topdressing; Combined with watering for topdressing, the filling stage of melon is carried out according to the principle of watering with fertilizer and eating less and eating more meals. When the root absorption fertility is weak in the middle stage of melon-bearing, organic fertilizer should be applied in combination with wide loosening soil. At the same time, root fertilization must be combined with chemical spraying during the whole growth period, and 2 1 16+ 1% fermented milk +0.5% urea solution should be sprayed continuously, once every 10 day and 0.3% ~ 0.4% phosphoric acid should be sprayed at intervals.
9, melon seedling management; Implement the management of unlimited growth of hanging seedlings. Cucumber seedlings are pulled up at the height of 180 cm, and a thin nylon rope is tied on the iron wire, which is 600 cm long. The tip of the rope is tied with melon seedlings, which are wound on the rope in an S-shape, and then tied on the top wire with a slipknot, and the excess part is wrapped into a ball and hung between the melon seedlings. After harvesting the lower part of the melon, remove the old leaves at the base, loosen the knot, drop the melon seedlings by releasing the rope, put the old seedlings in a ring shape after landing, and then tie the hanging rope to the top iron wire again. Repeatedly, the growth period of cucumber can reach about 300 days, and the yield of melon can reach as much as 30 thousand kilograms.
10, harvesting; Fruit cucumber grows rapidly, from sowing to picking commercial melons for about 55 days. Generally, there is no melon left at the root, so picking young melons in time is beneficial to plant growth, because the stronger the seedlings grow, the faster the melons grow, which will not affect the harvesting time. Early commercial melons should also be harvested early to increase early yield.
