Cucumber cultivation methods and technical details!

Cucumber is a kind of vegetable suitable for both young and old, which can be eaten raw or processed. At present, the market demand is growing. Below, we will explain in detail the cultivation methods and techniques of cucumber for reference.

I. cultivation methods of cucumber

From the point of view of the current popularized cucumber cultivation methods, there are mainly three cultivation modes: open-air cultivation, greenhouse cultivation and soilless cultivation.

1. Cucumber cultivated in the open air

Open-air cultivation of cucumber is a traditional way of cucumber cultivation in China, which is usually planted by directly planting and planting cucumbers. Open-air cultivation of cucumber has the advantage of low cost, but it is greatly affected by climate and season.

2. Cucumber cultivation in greenhouse

Cucumber cultivation in greenhouse is the most common way of cucumber cultivation at present, although the cost is higher, but it can be cultivated earlier or later according to the market trend, which is better than open-air cultivation in terms of ability to be lower than natural disasters.

3. Soilless cultivation of cucumber

It is understood that the yield of cucumber under soilless cultivation is second only to tomatoes. It is mainly divided into cucumber cultivated in bags and cucumbers cultivated in non-bag soilless culture. The culture medium can be selected according to local conditions. The main sources of materials include, but are not limited to, rice husk, grass carbon soil, perlite, vermiculite, washed sand, cinder, crushed straw and so on.

2. Key points of cultivation techniques of cucumber

Open-air cultivation, greenhouse cultivation and soilless cultivation of cucumber have their own emphasis on cultivation techniques.

1. Main points of cultivation techniques of open-air cucumber.

(1) Variety selection

Open-air cucumber cultivation should choose strong resistance, heat and drought resistance and easy cultivation, such as top melon 668, Yanqing Taiwan melon, Dingfeng 839, Kingfeng and other varieties.

(2) Disease and pest control

Open-air cultivation should focus on the control of cucumber diseases and insect pests, such as downy mildew, powdery mildew, anthracnose and so on.

2. Key techniques of cucumber cultivation in greenhouse.

(1) selection of greenhouse

Generally, the greenhouse selected for planting cucumber is the solar greenhouse, which mainly includes soil wall solar greenhouse and brick wall solar greenhouse. The former is suitable for out-of-season cultivation, and the cost is lower, but the life is easily affected by the weather, and the cost of the latter is higher. But sturdy and durable, the service life is at least more than 20 years.

(2) temperature control of greenhouse

Taking the slow seedling stage of tomato as the limit, the temperature should be kept at 25-30 ℃ during the day and 20 ℃ at night before the slow seedling stage, and 20-25 ℃ during the day and 15 degrees Celsius at night after the slow seedling stage.

3. Technical points of soilless cultivation of cucumber.

(1) preparation of matrix

The selection of soilless culture substrate materials was mentioned above, but these substrates still need to be steam sterilized and bagged when they are configured.

(2) selection of cucumber varieties.

Generally, the variety of cucumber selected in soilless cultivation is the Dutch "Zhuanggua". After the cucumber seeds were soaked and germinated, the seedlings were sowed and raised by the way of burrow plate seedling.

(3) preparation of nutrient solution

Soilless cultivation of cucumber generally does not apply fertilizer, but according to the actual growth of cucumber real-time preparation of nutrient solution, and then sprayed through the drip irrigation system.

Soilless cultivation needs specific greenhouse and substrate nutrient solution, so the production cost is relatively high, so the market price of cucumbers cultivated in soilless culture is much higher than that in open air and greenhouse.
