Which month is best for cucumber seedling cultivation (cucumber seedling cultivation method and time in early spring)

When is the best time to grow cucumber seedlings?

There are two main time periods for cucumber seedling cultivation. One is from January to March in early spring, when the climate is mild and the growth rate is fast, which is very conducive to germination. The other time is from June to August in summer and autumn.

The cultivation of cucumbers in the open field also depends on different regions and weather conditions. Generally speaking, cucumbers can be cultivated as long as they are not in the frost period. At present, if you harvest in autumn, there will be a better market price, which can increase your income.

Therefore, it is recommended that you start raising seedlings in late May to early June, and then start transplanting in July, so that you can harvest around the end of October .

It can be sold until early November. There are fewer vegetables on the market at this stage, so this kind of cyclical cultivation can sell for a good price.

If you are raising seedlings during this period, you need to choose loose soil, preferably sandy loam, because cucumbers have relatively high requirements for soil.

Moreover, there is more rain in various regions during this season. In order to avoid the impact of rain, sandy loam is more suitable and has faster drainage.

If the soil is heavy, you might as well bring some river sand and mix it into the field. After thorough plowing, you can achieve the effect of improving the soil.

How to grow cucumber seeds

Select suitable seeds, ensure good quality, screen the seeds, and pick out dry and damaged seeds.

Soak the seeds in hot water, keeping the temperature at about 55 degrees, and take them out after about half an hour.

After washing with clean water, soak it in clean water for 6-8 hours, then wrap it in wet gauze and place it in an environment of 25-30 degrees for germination. White spots will appear after 2-3 days.

Prepare the seedling tray and the soil, water it thoroughly, sow the seeds, cover them with a thin layer of soil, about 0.5-1 cm, and adjust the surrounding temperature to 24-30 degrees.

Seedling raising time of delayed autumn cucumber

The temperature varies from place to place, the speed at which the temperature drops in autumn varies greatly, and the duration of rainy and cloudy weather in winter is different, resulting in significant differences in the sowing and harvesting periods of delayed autumn cucumbers.

Especially in the south, the temperature in greenhouses is low. The main factor is that there is a lot of rainy weather, the temperature in the greenhouse cannot be raised, the light intensity is too poor, the humidity in the greenhouse is high, the growth and development are poor, and pests and diseases are rampant, which also causes differences in the sowing period.

The earliest sowing time is early July, and the latest sowing time is mid-September. Late sowing is suitable for greenhouse cultivation where the temperature can be maintained above 8°C in winter.

For greenhouses with poor insulation, the sowing period is generally more suitable in July and August. Harvesting should be stopped in early December, and the growing period should be kept at 90-100 days.

Cucumber seedlings are generally grown during the period of highest temperature. Strong light and high temperature, accompanied by strong winds and rainstorms, are very unfavorable for seedling cultivation. It is generally required to build rainproof sheds and shade sheds.

In the later period of the year, the light intensity is the worst and the sunshine time is the shortest. The temperature is low and it is difficult for cucumbers to grow. Therefore, you must choose high-quality varieties that are resistant to high temperatures, strong in stress resistance, strong in disease resistance and tolerant to weak light.

The seedling raising period is in an environment of high temperature and long daylight, with a small temperature difference between day and night. When the seedlings have 2-3 leaves, you can spray 100ppm ethephon solution to promote the differentiation of female flowers.

The seedlings are in a high temperature and high humidity environment, and the probability of downy mildew and blight is very high. You can irrigate the cucumbers every 10 days after the cucumbers emerge, and add high-quality mineral potassium humate to promote root growth and cultivate strong seedlings.
