Spring management technology of cucumber in greenhouse

Cucumber is a very common melon and fruit vegetable in our daily life. It is planted all over our country, and now the planting method of cucumber is mainly planted in greenhouse. If cucumbers are planted in the greenhouse, it is possible to grow cucumbers out of season. When planting cucumbers in the greenhouse, we need to do a good job of management according to the season. So how to manage cucumber in greenhouse in spring? Today, the editor brings you the management technology of cucumber in the greenhouse in spring. Let's take a look at it.

1. Carry out land preparation

The rhizome water content of cucumber seedlings is very large and brittle, so it is easy to break if it is not well managed when planting. Its waterlogging and drought tolerance is relatively poor. Therefore, we should pay attention to do a good job in soil preparation, in soil preparation, to ensure that the soil is flat, and to make it properly inclined to one direction. Improve the beat inertia of the soil to ensure that there is no large bumpy material in the soil and is rich in organic matter. When arable land, we should also pay attention to the layered application of sufficient mature organic fertilizer. Its fertilizer can be used with chicken manure, cake fertilizer and so on to ensure that the soil fertilizer is sufficient.

2. Soil disinfection

The multiple cropping index in the greenhouse soil is still relatively high, but the content of bacteria will also be relatively high. So we should also pay attention to do a good job of soil disinfection, can be used fulvic acid or carbendazim and other agents for disinfection. Mix it with fine soil, spread it over the head, and cultivate it by ridging. When ridging, we should give priority to wide and narrow rows. The wide line is kept around 80cm, and the narrow line is kept around 70cm. And dig a good watering ditch between the ridges and keep an appropriate amount of water in the ditch. Finally, the ridge is covered with a layer of plastic film to increase the ground temperature.

3. Timely planting

After the site preparation and disinfection has been done, we will have to plant it in a timely manner. When planting, we first need to plant a row on the ridge and on each side of the drain. The row spacing of the plant should be kept around 30*60cm. Control the amount of planting, do not plant too much per mu. And before the emergence of seedlings, we also used chlorothalonil in the seedbed sterilization once. After planting in the whole greenhouse, fumigants such as Subai tobacco and aphid lice fumigant were fumigated once in the greenhouse to reduce the incidence of diseases and insect pests.

4. Strengthen the management

When cucumber seedlings grow to about 30cm, it is necessary to do a good job of hanging seedlings and remove melon seedlings from the seedlings. Improve the permeability and promote its rapid growth. According to the actual situation of cucumbers to do a good job of watering. In the place where the cucumber grows, if the dew is beautiful in the morning or the temperature is good at noon, it should be watered under the film in time. And after the female flowers withered, appropriate amount of urea, potassium sulfate and other compound fertilizers should be properly applied to promote the expansion of melons and fruits and increase the yield. Finally, it is necessary to control the temperature, do a good job of ventilation, dehumidification and cooling, and protect the appropriate temperature difference between day and night.

The above is a brief introduction to the spring management technology of cucumber in greenhouse. That's all for today's introduction. This article is for reference only. I hope it can help you all.
