Method for planting two crops of red Bharati grapes a year in intelligent greenhouse

Abstract

The invention belongs to the technical field of agricultural planting, relating to a method for planting two crops of red Bharati grapes a year in an intelligent greenhouse. By means of advantages of the intelligent greenhouse, temperature and illumination in all growth periods of grapes are effectively regulated. By management measures such as reasonable watering and fertilizing, shoot keeping and pinching, leaf picking and pruning, dormancy breaking and pre-germination, winter buds can germinate in the current year so that the second growth period within the year is started. Therefore, the targets of obtaining economic yield by planting grapes in the same year and achieving one-year-two-harvest cultivation starting from the following year are fulfilled. The fruits in the first season come into the market in the late June and fruits in the second season appear on the market before Spring Festival after New Year Day, which means avoiding the marketing period for open cultivation of grapes in the North. The unit selling price of products is increased by 3-5 times and the twice total yield of fruits goes up by 50%. The time gap for ripening between fruits in the first season and fruits in the second season is over six months. Sufficient time is provided for grapevines to accumulate nutrients. Therefore, quality and yield of grapes in the first season are ensured while production of grapes in the following year is not affected.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and relates to a method for planting grapes, in particular to a method for planting red baratti grapes twice a year in an intelligent greenhouse. Background technique [0002] Grape is one of the main cultivated fruit trees in China, and has a cultivation history of more than 2,000 years in my country. Its fruit has high nutritional value, and the sugar content of fresh fruit is 10-30%. It contains a variety of minerals and vitamins beneficial to the human body, and is very popular among people. Since the middle and late 1990s, Eurasian grapes were successfully cultivated in sheltered areas south of the Yangtze River, the grape industry has developed rapidly, the cultivated area has expanded year by year, and the output has also continued to increase. However, due to the single main variety, poor storage and transportation resistance, and limited climate and environment, the ripeni...

Problems solved by technology

However, red Baratti grapes in the northern region are subject to temperature factors, so they can only be ripened once a year. Later, they can be cultivated in smart greenhouses to achieve twice a year. However, there is currently a lack of effective control and management, resulting in an increase in the second season. The problems of color difference, low sugar content and low yield will further affect the cultivation of the first season fruit
