Four Key Points for Spring Management of Greenhouse Cucumbers

Cucumbers are distributed very widely in our country and are welcomed by many people. Cucumbers can not only be eaten raw or stir-fried, but slicing them and applying the slices to the face also has a certain beauty and whitening effect. As spring gradually arrives, the management work for cucumbers is also gradually becoming busier. So what management precautions are there for cucumbers grown in greenhouses in spring? Below, the editor will introduce them to everyone. Let's take a look!

1. Land preparation and fertilization

In spring, cucumbers mostly exist as seedlings. The roots and stems of the seedlings have a high water content, so improper management can easily cause them to break. Cucumbers also have a relatively large demand for water, but their drought tolerance is rather weak. Therefore, when preparing the land in spring, we should make it appropriately sloped to facilitate planting and irrigation management. Then we should apply sufficient base fertilizer. During land preparation, decomposed farmyard manure should be applied in layers to increase the organic matter content in the soil. We must ensure that the soil environment and nutrients are suitable for cucumber growth and create a good growing environment for cucumbers.

2. Soil disinfection

If ridge cultivation is carried out for a long time, then the amount of bacteria in the soil is relatively high, so we also need to do a good job of disinfection when planting. Control the dosage according to the soil area. The main disinfectants are fulvate and carbendazim. When disinfecting, the disinfectant should not be directly scattered into the soil. It should be fully mixed with fine sand and then evenly sprinkled on the ridge head, and then the ridge should be formed by fine raking. When forming ridges, pay attention to controlling the specifications well to promote cucumber growth and facilitate farming operations in the middle and later stages.

3. Timely planting

Spring every year is a relatively good time to plant cucumbers. Before planting, we first need to do the first two preparation tasks well, and then dig water ditches around the ridges. Plant one row on each side of the water ditch. When planting, pay attention to the planting density. The plant and row spacing should be controlled at about 35*55 cm. It should not be planted too densely, to prevent affecting each other's growth. When the seedlings have successfully emerged and are ready to be lifted, use a sterilizing agent to carry out one sterilization treatment. Then after all planting is successful, carry out one closed-greenhouse fumigation treatment on the greenhouse again to avoid pest damage.

4. Careful management

When the cucumber seedlings grow to about 32 cm, pay attention to hanging the vines to improve the air permeability in the garden and the growth speed of the cucumbers. Then water at the appropriate time every morning. If the leaves are found to be in a wilted state at noon, water them promptly as well. Also pay attention to observation. After female flowers wither, topdress promptly. The fertilizer should mainly be compound fertilizers such as urea. This promotes cucumber expansion and increases yield. Then control the daytime temperature at about 26-27 degrees, lower it to about 16 degrees at night, and pay attention to ventilation to reduce humidity and temperature.

The above is a brief introduction to the four precautions for spring management of greenhouse cucumbers. Spring is generally the sowing season for cucumbers. Therefore, their management work is very important, so everyone must pay close attention when planting. That is all for today's introduction. This article is for reference only.
