Cucumber Production Under Proper Greenhouse Conditions

In this blog post below,we have analyzed a guide on how to produce cucumber under proper greenhouse condition.

The Important of produce cucumber under greenhouse

It is clear that cucumber plants have very big leaves, grow vigorously, and require large amounts of sunlight. For each plant to thrive. Under good sunlight condition, each plant should be provided from 5 to 7 square feet of greenhouse space. Also, plants often require more space, where light amount is poor. Cucumbers responds and grows best only when the conditions of high temperature, humidity, and light intensity combinesd with a constant and plentiful supply of water and nutrients in order to achieve be cost-effective and sustainable goals.

 

Therefore, we people tend to grow in commercial greenhouses, especially in cold places, such as Russia, Siberia, Uzbekistan, Ohio, USA, and Ontario, Canada, etc. It is crucial for growers to make the right decisions about climate control, nutrient management, pest control and sunlight management.

 

Climate Condition

Cucumbers demand very stable climate condition. The ideal humidity should be around 60% to 70% during the day and higher at night. While maintaining precise temperatures is necessary in order to optimize the production of cucumbers, there is a relationship between temperature and light. Even though cucumbers can grow with less than 12 hours of light, INSONSHADE’s highly transparent energy saving screen prevents heat loss, allows valuable daylight in, and ensures the best possible climate for growing. In this way, the transparent screen can be used together with the diffusing screen at the same time. Its will make the sunlight even distribution. 

The Working Principle of Energy Saving Screens and light diffusion screens

The screens with maximum transmittance fully meet the lighting needs of cucumber vegetation.  Additionally, they effectively reduce the heat loss of the greenhouse and achieve the purpose of energy saving, energy saving and heat preservation.

When the night comes, the screen’s knitted construction protects the screen to avoid the formation of condensation.

When sunlight is better distributed and can penetrate further into the greenhouse, this facilitates the absorption of light of a consistent quality by the cucumber seedlings. Moreover, diffuse and indirect sunlight reduces the risk of leaf burn.

Soil

The soil for cucumbers should be rich, but not too heavy. One month before planting, amending the soil with compost and manure it is important to have a good media and soil depth; the recommended pH range for good plant development is from 5.5 to 6.8.

Humidity

Careful management of humidity in the greenhouse is an vital part of maintaining both crop production and crop health. Humidity can influence everything from plant growth rates to disease problems. This is because cucumbers perform well under conditions of high relative humidity.

Watering

 In low humidity condition, water supply is critical. Cucumbers which grow at lower relative humidity condition require a lot of water, and water shortage causes misshapen fruits, abortion, or less vigor to sprout secondary shoots. It is very necessary to ensure the availability of water, especially after the beginning of harvesting.

Pests and diseases

Greenhouse humidity can also affect the presence of pests and diseases. The risk of infection will increase if the leaf surface becomes wet from water droplets, condensation or misting. Western flower thrips a very dangerous pest in cucumber greenhouses. They feed on flowers and plant material and have the ability to wreak havoc due to the viruses they carry. They have rapidly spread throughout the greenhouse due to the transport of cargo containing materials and plants. The reproductive rate of thrips is mainly temperature dependent, so around 30º C can increase faster. This unusual and highly fertile population of thrips. In addition, due to poor control, coupled with resistance to pesticides, thrips easily overwinter in greenhouses. 

Pest Control

Using insect screen to exclude thrips may seem like an obvious and simple solution, but the selection process requires thoughtful consideration, as careful attention must be paid to mesh design, function, and characteristics.

Fertilizering

Soil Production:

Generally, cucumbers are heavy feeders so they require regular use of large amounts of fertilizer, no more than 65 tons per acre on poor soils. As a pre-plant treatment, adding phosphorus at 800 to 1,000 lbs. ssp/acre, cucumbers may require weekly feedings of a balanced solution of fertilizers such as 10-52-17, the amount of which is best determined by tissue analysis.

Hydroponic Production:

Good nutrient medium composition and balance are important.

Hydroponics allows the production of vegetables in areas where there is no suitable soil or diseases or other conditions that make ground bed production impractical.

Irrigation

Irrigation keeps the roots of cucumber plants well-watered. Excessive water reduces soil aeration. Seedlings in the greenhouse in mid-winter may need to be watered every two weeks. The same plants may need water every day on a hot summer day, with an estimation of 1/4 to 3/4 gallon per plant per day, depending on size.

Harvesting

A cucumber crop matures within 40 – 50 days and harvesting starts 45 – 55 days after planting.
