Rice Cultivation in Greenhouse
What is Rice Cultivation in Greenhouses?
Rice cultivation in greenhouses involves growing rice crops within a controlled environment, such as a greenhouse. This method allows farmers to manipulate factors such as temperature, humidity, and light to create ideal growing conditions for the rice plants. By controlling these factors, farmers can increase the yield and quality of their crops, reduce the risk of pests and diseases, and minimize the impact of adverse weather conditions. This type of rice cultivation in greenhouses provides a sustainable and profitable alternative to traditional farming methods.
The Basics of Rice Cultivation in Greenhouse
- The first step in cultivating rice is to select a suitable variety for greenhouse cultivation.
- Rice should be grown in a soilless or hydroponic system in the Greenhouse.
- The ideal temperature for rice growth is 25-30°C during the day and 20-25°C at night.
- Rice requires a minimum of 12-14 hours of light daily, and supplemental lighting may be necessary during winter.
- The pH should be maintained between 5.5 and 6.5.
- Rice requires high levels of nitrogen, phosphorus, potassium, and other micronutrients.
- Pest and disease control measures should be taken to prevent damage to the rice plants.
- Harvesting should be done when the rice grains have matured and turned brown.
The Benefits of Greenhouse Rice Cultivation
- Controlled Environment: Greenhouses offer a controlled environment for rice cultivation, which enables farmers to regulate temperature, humidity, and light to optimize plant growth and yield.
- Pest Control: Greenhouses protect rice crops from pests, diseases, and harsh weather conditions, reducing the need for chemical pesticides and increasing the quality of the harvested grains.
- Water Conservation: Greenhouse rice cultivation requires less water than traditional outdoor methods due to recycling irrigation water and controlling the soil’s moisture level.
- Improved Yield: Greenhouse rice cultivation can lead to higher yield and quality of the harvested grains, resulting in higher profits for farmers.
- Reduced Labor Costs: Greenhouse rice cultivation requires less manual labor than traditional outdoor methods, allowing farmers to manage labor costs and increase productivity.
- Year-round Cultivation: Greenhouse rice cultivation can produce year-round rice, allowing farmers to increase their income and meet market demands.
According to research conducted by Purdue University, greenhouse rice cultivation can increase rice yield by up to 35% compared to traditional outdoor cultivation methods. Additionally, using greenhouses can reduce water usage by up to 30% and significantly reduce the use of chemical pesticides.
Material Required to Setup Up a Rice Greenhouse
- Site Selection: Choose a flat and well-drained site with access to a reliable water source and proper sunlight exposure.
- Greenhouse Structure: A greenhouse structure of galvanized steel, aluminum, wood, and polyethylene film covering is recommended. The size and shape of the Greenhouse can vary depending on the farm’s needs and the space available.
- Flooring: A gravel or concrete floor is recommended to provide a stable surface for the Greenhouse.
- Irrigation System: A drip irrigation system is ideal for rice cultivation. It is essential to have a reliable water source, a water storage tank, and a pump to ensure a consistent water supply to the plants.
- Ventilation System: A ventilation system is required to maintain the temperature and humidity inside the Greenhouse. The ventilation system should include fans and vents to maintain optimal conditions for rice growth.
- Rice Seeds: Choose high-quality rice seeds adapted to the local growing conditions.
- Fertilizers and Pesticides: Choose organic fertilizers and pesticides to ensure a safe and healthy crop.
- Sterilized Soil, clay, or silt loam: Sterilized soil has been treated to eliminate pathogens or contaminants that may harm the rice plants. Clay or silt loam soil is ideal for rice cultivation as it holds moisture well.
- Commercial Potting Mix: A commercial potting mix can supplement the soil and provide additional nutrients for the rice plants.
- 8 ½” Diameter x 7.5″ Plastic Pots: These pots are ideal for starting rice seedlings as they provide a stable environment for the young plants.
- Nitrogen Fertilizer (Pelletized Urea): Nitrogen is essential for rice growth, and pelletized Urea is a common source of nitrogen fertilizer for rice cultivation.
- Tools and Equipment: Basic tools such as shovels, hoes, rakes, and pruning shears are required for planting, pruning, and harvesting.
The cost of setting up a rice greenhouse can change depending on the size of the Greenhouse and the materials used. According to a study conducted in Taiwan, the cost of setting up a greenhouse for rice cultivation can range from $5,000 to $15,000.
How to Grow Rice in the Greenhouse
Growing rice in a greenhouse is a relatively new concept gaining popularity due to its numerous benefits. Unlike traditional rice farming, growing rice in a controlled environment like a greenhouse allows farmers more control over the growing conditions, leading to higher yields and better quality rice. Additionally, greenhouse cultivation of rice reduces the impact of environmental factors like pests, diseases, and weather conditions, making it a more sustainable and reliable option for farmers.
Soil Preparation for Growing Rice in the Greenhouse
- Use sterilized soil, which can be either sterilized and sized field soil to remove rocks or small amounts of autoclaved soil.
- Mix two parts sterile soil with 1 part commercial potting mix to create a suitable growing medium for the rice plants.
- Fill 8 ½” diameter x 7.5″ tall plastic pots with the soil mix, leaving 2 inches from the top.
Planting Rice Seeds in the Greenhouse
- Moisten the soil before planting seeds, but avoid standing water.
- Plant up to 5-7 seeds per pot at ½ inch depth and lightly cover them with soil.
- Keep the pots moistened at least daily through germination, which can occur between 5-10 days after planting.
Applying Fertilizer and Water to Rice Grown in Greenhouse
- Applying 1/8 teaspoon nitrogen (pelletized Urea) per pot when four leaves have emerged.
- To ensure a permanent flood, keep the water level 1 to 112 inches deep and equal to the top of the pot.
- Water the plants in the morning to allow the foliage to dry before dark.
Growth and Flowering of Rice in a Greenhouse
- The plant will increase water uptake and express panicles during the reproductive stage, which occurs about 60-100 days after planting.
- Flowering normally occurs in the morning, with pollination around mid-morning (9-10 a.m.).
- The panicles will begin to tilt over as the seeds ripen and mature, and the seeds will dry and turn brown.
Harvesting and Storage of Rice Grown in a Greenhouse
- Once the seed is ready for harvest, cut the panicles and leave them on a greenhouse table for several days to dry further.
- Harvested panicles can be placed into paper bags or envelopes.
- For long-term seed material storage, use cold storage (ca. 40º F, 20% RH).
Conditions Required for Rice Grown in Greenhouse
Maintaining optimal growing conditions, such as temperature and lighting, is essential to ensure healthy plant growth. The greenhouse conditions should be controlled with a minimum of 70º F at night and a maximum of 85-90º F during the day. The lighting conditions should be controlled with a 12-hour day during winter and a normal day length during summer.
Growing rice in a greenhouse is an efficient and sustainable way to cultivate this essential food crop. With proper soil preparation, planting, fertilizing, watering, and harvesting techniques, rice can be grown successfully in a greenhouse. By providing a controlled environment, greenhouse cultivation can lead to higher crop yields, better quality rice, and a reduced environmental impact compared to traditional open-field cultivation.
