What is the effect of greenhouse in gardening?

Plants require warmth, humidity, and light for growth. A greenhouse stabilizes the growing environment by buffering ambient temperature and protecting plants from extreme cold, extending the growing season and enabling early sowing and harvest. By sowing successionally, greenhouse growers can reap early harvests, especially by nurturing late-sown seedlings.

The greenhouse also protects plants from pests and diseases, allowing them to become an oasis free from flying pests like adult aphids and egg-laying butterflies. By implementing biological controls and limiting access to the greenhouse, pests can be minimized without toxic chemicals. This allows for organic produce for the family.

Tomatoes can be grown in a greenhouse environment to minimize plant diseases like blight. Fungal spores are less likely to reach plants, and the growing conditions inside the greenhouse are less conducive for fungi to infect them. By choosing blight-resistant varieties, tomato blight can be virtually eradicated, providing a significant advantage over growing outside.

Is greenhouse farming bad for the environment?

The intensive agricultural methods used in greenhouses can damage local environments by overtaxing water supplies and polluting rivers and soils with nutrients, pesticides, and plastic waste. However, the impact of these seas of plastic on local temperatures can be even more dramatic and beneficial. They increase the albedo, or reflectivity, of the land surface, typically by around a tenth, and reduce solar heating of the lower atmosphere. A new satellite mapping exercise revealed the extent of the planet’s growing enthusiasm for greenhouses, estimated at 3.

2 million acres, with China hosting more than half of this expanse. The albedo iceberg is not just the surface, with temporary coverings of crops by reflective plastic sheets potentially increasing the figure by 10 times.

What is a main benefit of the greenhouse effect?

Greenhouse gases play a crucial role in maintaining Earth’s temperature for life. Without the natural greenhouse effect, Earth’s heat would escape into space, resulting in an average temperature of around -20°C. The greenhouse effect occurs when most infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted by greenhouse gas molecules and clouds. This warms the Earth’s surface and lower atmosphere.

Greenhouse gases absorb infrared radiation in the form of heat, which is circulated in the atmosphere and eventually lost to space. They also increase the rate at which the atmosphere can absorb short-wave radiation from the Sun, but this has a weaker effect on global temperatures.

What is a greenhouse and its importance?

A greenhouse is a building designed to protect plants from excessive cold or heat. It evolved from brick or timber shelters in the 17th century to a roofed and walled structure built of glass with minimal wooden or metal skeleton. By the mid-19th century, greenhouses had evolved from a refuge from a hostile climate into a controlled environment, adapted to the needs of particular plants. Large greenhouses are important in agriculture, horticulture, and botanical science, while smaller structures are commonly used by hobbyists, collectors, and home gardeners.

Modern greenhouses are usually glass- or plastic-enclosed framed structures used for producing fruits, vegetables, flowers, and other plants that require special temperature conditions. The basic structural forms include the span-type greenhouse, which has a double-sloped roof, and the lean-to greenhouse, which has only one roof slope and leans against the side of a building. Glass is the traditional glazing material, but plastic films, polyethylene, polyvinyl, and fibreglass are also common. The framing of the structure is made of aluminum, galvanized steel, or woods like redwood, cedar, or cypress.

Plants grown in greenhouses fall into several broad categories based on their temperature requirements during nighttime hours. Cool greenhouses have nighttime temperatures of 7-10°C (45-50°F), suitable for azaleas, cinerarias, cyclamens, carnations, fuchsias, geraniums, sweet peas, snapdragons, bulbous plants, daffodils, irises, tulips, hyacinths, and narcissi. Warm greenhouses have nighttime temperatures of 10-13°C (50-55°F), suitable for beonias, gloxinias, African violets, chrysanthemums, orchids, roses, coleuses, ferns, cacti, and other succulents. Tropical greenhouses have nighttime temperatures of 16-21°C (60-70°F), suitable for caladiums, philodendrons, gardenias, poinsettias, bougainvilleas, passionflowers, palms, and orchids.

How does the greenhouse effect affect farming?

Climate change is posing significant challenges to agriculture and fisheries, as it affects the growth of plants, livestock, and fish. Moderate warming and increased carbon dioxide in the atmosphere may help some plants grow faster, but severe warming, floods, and drought may reduce yields. Livestock may be at risk from heat stress and reduced food supply quality. Agriculture and fisheries are highly dependent on climate, with climate changes potentially increasing crop yields in some areas but also affecting nutrient levels, soil moisture, water availability, and other conditions.

Changes in drought frequency and severity could pose challenges for farmers and ranchers, and threaten food safety. Warmer water temperatures may also cause habitat shifts for fish and shellfish species, disrupting ecosystems. Overall, climate change could make it more difficult to grow crops, raise animals, and catch fish in the same ways and places as in the past.
