Planting skills of Fruit Cucumber

Techniques for planting fruits and cucumbers

First, raising seedlings

The seed price of cucumber is expensive, so you can use a hole plate or nutrition bowl to sow seeds. The temperature of planting forest is very high, and the optimum temperature for germination is 24 ℃-26 ℃, which usually emerges in 4 days. After emergence, it kept 23 ℃-25 ℃ during the day and 16 ℃-18 ℃ at night. The root system likes dampness and fear of waterlogging, temperature and cold, and exuberant aerobic respiration. Be sure to choose substrates with good ventilation, heat preservation, fertilizer retention, water seepage and moisturizing ability, such as peat, vermiculite, perlite, cocoa peat and so on.

II. Colonization

Small cucumber has larger leaves, early fruiting period and continuous fruiting, but its root absorption capacity is weak, so it is necessary to make fine soil preparation before planting, apply a large amount of organic fertilizer, and apply more than 5000 kg of rotten livestock manure in 667m2, plus some compound fertilizer. Make a small high border with a width of 1 to 1.2 meters. The seedling planting standard is 2-4 true leaves, the seedling age is 25 days, and the density is 2500 plants / 667m ~ 2. Watering the seedling immediately after planting is beneficial to the development of the root system.

III. Field management

1. After planting with fertilizer and water, the seedlings were watered with a small amount of slow seedling water for 4 days to promote the slow seedling. Slow down the seedlings and then water them with fertilizer per water. 10 kg of urea is applied every 667 square meters and irrigated once every 5-7 days. During the melon-bearing period, 0.2%-0.3% potassium dihydrogen phosphate was sprayed once a week. The air humidity is kept at 80%.

two。 Within one week of planting, the temperature was kept at 25 ℃ ~ 30 ℃ in daytime, 18 ℃-20 ℃ at night, and no more than 35 ℃. The temperature should be lowered after slow seedling, 22 ℃ ~ 25 ℃ in daytime and 16 ℃ ~ 18 ℃ at night.

3. Dutch cucumber has strong tolerance to weak light, and higher yield can be obtained under low light in winter. When it is hot and bright in summer, be sure to cover the sunshade net.

4. If carbon dioxide fertilization is possible, carbon dioxide gas fertilizer should be properly supplemented to make the indoor carbon dioxide concentration reach 750 mg / kg, and the cucumber yield will increase by 20%.
