Problems solved by technology

[0002] Many vegetable growers treat bacterial angular spot caused by copper deficiency as fungal downy mildew for prevention and treatment, resulting in misdiagnosis and severe yield reduction; downy mildew caused by potassium deficiency does not pay attention to potassium supplementation, which eventually leads to seedling damage

Embodiment

[0017] [Temperature] The room temperature is controlled at 25°C to 32°C during the day, 18°C ​​to 16°C in the first half of the night, and 10°C to 12°C in the second half of the night; balance between aboveground and underground, vegetative growth and reproductive growth. When there are few small melons, the daytime temperature drops to 20°C-24°C to induce young melons; when there are many small melons, raise the temperature to 30°C-32°C to promote the growth of melons.

[0018] [Moisture] The relative air humidity is required to be kept at 85% during the fruiting period. There are two seams on the south edge and the top of the greenhouse to drain moisture in time. It can be watered above 20°C, and keep small water in the middle and late stages of growth. It is required to keep the soil nitrogen content of 100 mg / kg, phosphorus content of 24-40 mg / kg, and potassium content of 240 mg / kg. The best application amount of 45% biological potassium is 24 kg each time, and the soil w...

Abstract

The invention discloses a middle late-stage cultivation method of cucumber. The method comprises the following steps of: temperature: the room temperature is controlled between 25 and 32 DEG C on the day, between 18 and 16 DEG C on the first half of the night, and between 10 and 12 DEG C on the second half of the night; moisture: the relative air humidity is required to be maintained at 85% in the fruiting period; illumination: the lower limit of illumination is 10000 lux, and the upper limit of illumination is 55,000 lux; vine tying: yellow leaves, old leaves, too dense leaves, damaged leaves, diseased leaves and axillary buds are removed to prevent from generating ethylene to accelerate the aging or waste nutrition: gas: in a hour after the sun comes out on the day, carbon dioxide generated at night is absorbed, and is manually supplemented in 10 to 12 hours; dead plant prevention: after the second crop or when the blight is found, 2 kg of copper sulfate is watered per 667 square meters or a bio-fertilizer is frequently used to occupy niches; nutrient supplementation to prevent diseases; coverings; a straw curtain is taken off early and is covered early in winter, so that the plants are lightened early and the night temperature is high; in the high-temperature long-sunshine period, the straw curtain is taken off late and is covered early to create a short-sunshine environment to promote to produce female cucumber. The investment is less, and the economical effect is better.

Description

technical field [0001] The invention relates to a method for cultivating cucumbers, in particular to a method for cultivating cucumbers in the middle and late stages. Background technique [0002] Many vegetable growers treat bacterial angular spot caused by copper deficiency as fungal downy mildew for prevention and treatment, resulting in misdiagnosis and severe yield reduction; downy mildew caused by potassium deficiency does not pay attention to potassium supplementation, which eventually leads to seedling damage. In addition, the phenomenon of bent melons caused by boron deficiency is more common. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating cucumbers in the middle and late stages; not only can avoid severe yield reduction, but also can supplement potassium and avoid the phenomenon of bent melons, and correspondingly improve economic benefits. [0004] Technical scheme of the present invention is: [0...
