Cucumber cultivation is a form of cucumber cultivation that continues to be produced in the summer and autumn when the cucumbers are no longer growing, using temperature-preservative cream from the sheds. At this point in time, the climatic characteristics are the opposite of those of early spring production, with high temperatures and rainy seasons in the early stages, followed by sharp cooling. Therefore, the choice of species requires a strong resistance to disease, early guacamole, denseness and the harvesting of concentrated varieties。
Sowing and planting
The planting of large cucumbers after the fall is expected to take care of the period of sowing if it is too early to be affected by high temperature and rain weather conditions, leading to a variety of diseases, and the possibility of encounters with land cucumbers during the market period at lower prices; too late the sowing period and a sharp drop in post-growth temperatures could lead to lower yields. So choosing the right planting period is the key to the fall cucumber cultivation。
In autumn, the cucumber shed is grown for approximately 40 days, with a nursery period of about 20 days, and the seedlings are planted at a single heart, and the planting time should be set in the evening, either by live broadcasting or by high planting, suitable planting density behaviour of 65 centimetres, small behaviour of 40 centimetres, with a distance of about 26 centimetres, or 5,300 plants per acre。
The cucumber, which is broadcast live, shall be nucumbered immediately upon seeding. Masha spreads the sapling, and two saplings are set. When seedlings, disease seedlings, malformation seedlings and seedlings are detected, they should be replaced in a timely manner。
The seedlings, which had been sprayed with ethylene during the planting period, would no longer need to be sprayed. The live cucumber can be sprayed once after the expansion of the cucumber's two real leaves and once during the four real leaves. Spraying should take place at 3-4 p. M. And be followed by timely watering。
Field management
The cultivation of the fall cucumbers includes, inter alia, high-temperature management in the preceding period, medium-term moderate management and later low-temperature management in the second half of the year, three parts of the first part of the period of high-temperature and heavy rainfall. Care should be taken to protect the rain against weather variability, water should be drained in a timely manner after rain, water should not accumulate in the fields, weather should be clear, water should be poured in time, water should be cooled for the seedlings, water should be applied together after entering the condensation period, water should be used in small quantities, water should be prevented from flooding large water, and the focus of the management has become cold-proof in the latter part, that is, after mid-october, while attention should be paid to regularly replacing the melon with ventilation, maintaining a good permeability, preventing the spread of disease by excessive weting, and following periods can be followed by leaf-caping, such as plant-powered 2003, leaf-faced, spraying。
Post and temperature
When the cucumber grows to a certain height, it is necessary to raise a human-shaped frame in time, usually with a two-metre-high shelf for each seedling. When the seedling grows to the top of the cucumber, the side branch below 50 centimeters is removed in time for ventilation, and the other side branches can leave a leaf behind the female。
The production of cucumbers in the fall, with special attention to temperature control in the shed, creates comfortable growth conditions for seedling growth wherever possible. It is possible to sow a pre-sown shed that will lift four weeks of thin membrane to reduce temperature and humidity in the shed; to gradually decentralize the membrane that has been rolled up four weeks after the gradual drop in temperature in mid-september until the membrane is stretched; to the extent that the temperature in the shed is relatively comfortable between mid-september and mid-october, which will greatly facilitate the growth and development of cucumbers, and to keep ventilated for more than five hours in the shed at 25-30°c in the morning and at noon, to gradually reduce ventilation at night, to 15-18°c in the shed, which can be pressed only when the external temperature is below 15°c。
With lower external temperatures and lower temperatures in the sheds, the management focus is on taking all measures to keep the shed warm。
