Know the prevention and control methods of edible fungus diseases and how to irrigate the greenhouse flower production

Sprinkler irrigation, also known as artificial rainfall, is a semi-automatic irrigation method that uses sprinkler irrigation equipment to spray water into the air and fall to the ground under high pressure. Sprinkler irrigation can be combined with foliar fertilization, drug control and other management at the same time, with the advantages of saving water, easy to control, labor-saving and efficient, does not destroy soil structure, can wash plant surface dust, adjust microclimate, and is suitable for all kinds of topography. However, the equipment has a large investment and can not be used in windy areas or windy seasons. The size of fog droplets should be appropriate when sprinkler irrigation is applied.

Based on the original sprinkler irrigation technology, micro-spraying technology has been gradually popularized in the greenhouse production of flowers. Micro-spraying is an efficient and economical sprinkler irrigation technology. the micro-spraying system is designed according to the production characteristics of horticultural plant greenhouse, which is especially suitable for large-scale production of all kinds of flowers and vegetables. The water belt of the micro-spraying system adopts the upward type, and the spray water atomization degree is high, which is like a continuous drizzle, which is not easy to damage all kinds of plants, and can increase plant photosynthesis and promote crop growth, which can save water and labor, and can be combined with fertilizer and pesticide spraying, which will not cause soil erosion and fertilizer loss.

To sum up, micro-spray has the following advantages: first, excellent atomization, large coverage, sufficient humidity, strong heat preservation and cooling ability, and increase output; second, low cost, quick recovery of one-time investment, and easy and fast installation; third, it has anti-drip design, time-saving, water-saving, labor-saving, can be combined with automatic spraying, extra-root fertilization; fourth, the service life is long, and the sprinkler is easy to replace. Fifth, it can also be applied to orchard sprinkler irrigation (such as litchi, longan), the leaves and fruits of plants can be evenly sprayed. In a word, the micro-spray system overcomes all kinds of shortcomings of towing and spraying water in greenhouse production in the past, and is simple and practical.
