Cucumber is widely distributed in China and is welcomed by many people. Cucumbers can not only be eaten raw and fried, cut into slices and applied on the face, but also have a certain beauty and whitening effect. With now gradually entering the spring, the management of cucumbers is also gradually busy. So are there any management precautions for cucumbers grown in greenhouse in spring? Next, the editor will introduce to you, let's have a look!

1. Soil preparation and fertilization

Cucumber mostly exists in the form of seedlings in spring, and the water content of seedlings is large, so it is easy to break if it is not managed properly, and cucumbers have a large demand for water, but their drought tolerance is relatively weak. Therefore, we should tilt properly when preparing the soil in spring to facilitate the management of planting and row management. Then it is necessary to apply sufficient base fertilizer and apply corroded farm manure in layers during soil preparation to improve the content of organic matter in the soil. It is necessary to ensure that the soil environment and nutrition are suitable for the growth of cucumber and create a good growth environment for cucumber.

2. Soil disinfection

If it is cultivated in ridges for a long time, then the content of bacteria in the soil is relatively large, so we still need to do a good job of disinfection when planting. According to the soil area to control the dosage, the main disinfectant is fulvic acid salt and carbendazim. Disinfection should not be sprinkled directly into the soil, it should be fully stirred with fine sand and sprinkled evenly on the ridge, and then fine rake ridges. When ridging, we should pay attention to control the specifications, promote the growth of cucumber, and facilitate the planting and farming operation in the middle and later stage.

3. Timely planting

Spring is a good time to plant cucumbers every year. We need to do the first two preparations before planting, and then dig ditches around the ridges. One row should be planted on both sides of the ditch, and the planting density should be paid attention to when planting, and the row spacing should be controlled at about 35-55 cm. It is not suitable to plant too densely to prevent mutual influence on growth. When successful emergence of seedlings to prepare seedlings, it is necessary to use fungicides to do a sterilization work. Then, after all the planting is successful, the greenhouse should be fumigated again to avoid insect pests.

4. Careful management

When cucumber seedlings grow to about 32 cm, attention should be paid to hanging seedlings to improve the permeability of the garden and the growth rate of cucumbers. Then every morning timely watering, such as in the noon when the leaves are found to be in a withered state, but also timely watering. And should pay attention to observation, found that the female flower withered behind, should be timely topdressing, fertilizer such as urea and other compound fertilizer. Promote the expansion of cucumber and increase the yield. Then it is necessary to control the temperature at about 26-27 degrees during the day, reduce it to about 16 degrees at night, and then pay attention to ventilation to reduce humidity and temperature.
