Strawberries taste great and have high nutritional value, but growing them is not easy. From temperature and humidity control to disease prevention, any mistake at any stage can hurt yields or even wipe out the crop. Strawberries are a typical high-value crop in greenhouse farming. Below is a look at common problems in strawberry greenhouse cultivation and how smart farm equipment can help.
Key pain points in strawberry cultivation
Disease control is the biggest challenge. Strawberries are prone to gray mold, anthracnose, and leaf spot. The main causes are high humidity inside the greenhouse, especially during flowering and harvest, which creates ideal conditions for fungus. Traditional manual spraying often misses the undersides of leaves and the base of the plants. Continuous cropping also allows soil-borne pathogens to build up over time.
Environmental control is also demanding. Strawberries need at least six hours of light per day. Less than that, and seedlings stretch too much and flower bud formation suffers. During flowering, daytime temperatures should be between 20-25°C and nighttime temperatures between 8-10°C. Anything above 30°C or below 5°C affects pollination and fruit set. Humidity during flowering should be kept between 50-60%. Above 70%, the risk of gray mold goes up sharply. Soil pH should stay between 5.5 and 6.5. If it gets too alkaline, the plants can’t absorb iron and manganese, and the leaves turn yellow.
Water and fertilizer management is also tricky. Strawberries have shallow roots and don’t handle drought or waterlogging well. Traditional watering by feel often causes problems. Too much water during flowering leads to flower and fruit drop. Not enough water and fertilizer during fruit expansion affects fruit size and sugar content. Too much humidity during harvest causes fruit to rot and shortens shelf life.
How equipment solves these problems
To address the issues above, this setup is built around three things: environmental monitoring, smart control, and precision spraying.
The smart climate control system makes the environment manageable. At different growth stages, the system automatically controls fans, cooling pads, shade screens, and heaters. When nighttime temperatures drop below 8°C during flowering, the system turns on heating. When daytime temperatures go above 25°C, it starts ventilation. On cloudy days or when light is low, the system turns on LED grow lights to make sure plants get enough light each day. All environmental data – temperature, humidity, light intensity, and CO₂ levels – is sent to a phone or computer in real time. Growers can check historical trends whenever they want.
The smart fertigation system delivers water and nutrients as needed. Different irrigation and fertilization schedules can be preset for the seedling stage, flowering stage, fruit expansion stage, and harvest stage. During flowering, the system automatically reduces watering to prevent flower drop. During fruit expansion, it increases water and nutrient supply and adds high-potassium fertilizer to boost fruit size and sugar content. Growers can adjust the schedule from a phone, and the system runs automatically. No one needs to be in the field to turn valves on and off.
The automated spraying robot solves the problem of uneven coverage. Traditional spraying is inefficient and often misses spots. The robot uses nozzle technology to break the spray into ultra-fine particles under 35 microns. These particles stick to the undersides of leaves and the base of the plants. The robot walks along a set path and can be controlled remotely or run on a preset route. The application rate is precise, so there’s no overlap or missed areas. The whole process runs without a person in the greenhouse, which also reduces health risks from pesticide exposure.
Soil sensors and pH monitoring protect root health. Multi-layer soil sensors are placed around the root zone to monitor soil moisture, temperature, EC, and pH in real time. When pH goes outside the 5.5-6.5 range, the system sends an alert and adjusts it by injecting acid or alkali through the fertigation system.
Weather monitoring and pest detection systems can be added as well. The weather station measures air temperature, humidity, light, rainfall, wind speed and direction, and other data, which can be shown on a large LED screen. The pest detection system tracks insect populations, analyzes trends, and helps growers predict outbreaks. It automatically separates insects from water and collects specimens, giving growers time to prepare for prevention.
The IoT management platform and mobile app bring all the data together. A large dashboard screen lets growers monitor equipment and environmental data in real time, assign tasks to workers, and receive alerts. Through the mobile app, growers can check conditions in each greenhouse from anywhere, control equipment remotely, and get notifications when something needs attention.
Actual results
Take a strawberry greenhouse in eastern China as an example. After switching to this system:
- Gray mold rates dropped by about 40%. Chemical pesticide use went down by 25%.
- Marketable fruit rate increased by 18%. Fruit uniformity improved noticeably.
- Water use dropped by more than 35%. Fertilizer efficiency went up by 30%.
- Labor costs fell significantly. A 10-acre greenhouse that used to need three people to manage can now be handled by one person using a phone. The farm saved over 60,000 RMB a year in labor.
- Fruit quality also improved. Average sugar content went up by 1.2 degrees. The fruit looked better and held up longer during transport.
Which greenhouse crops this works for
This system was designed with strawberries in mind, but it works just as well for tomatoes, cucumbers, bell peppers, blueberries, and other greenhouse crops. Temperature and humidity requirements, water and fertilizer schedules, and disease prevention strategies can all be adjusted in the system.
