Embodiment 1

[0018] In July 2017, the experiment site was located in Pancheng Town, Pukou District, Nanjing City, Jiangsu Province. The experimental variety is Xiahei, which is a four-year-old. The daily maximum temperature during the entire test period was above 30°C. At the same time, three grape greenhouses with the same area and conditions were tested. Greenhouse 1 adopted traditional ventilation and shading cooling management, Greenhouse 2 adopted traditional ventilation and shading cooling management and added water curtain cooling management, and Greenhouse 3 adopted the following methods for cooling management.

[0019] For extreme high temperature weather, the temperature conditions, light conditions, relative humidity of the atmosphere, and soil moisture in the grape greenhouse are regulated, and grape high-temperature-resistant foliar fertilizers are sprayed.

[0020] Temperature is one of the most important factors affecting the growth of grapes. In this embodiment, the adjust...

Embodiment 2

[0029] In July 2018, the experiment site was located in Pancheng Town, Nanjing City, Jiangsu Province. The experimental variety is five-year-old Xiahei. The daily maximum temperature during the entire test period was above 30°C. At the same time, the control group experiment of traditional ventilation, sunshade and cooling treatment was carried out.

[0030] For high temperature weather, according to the environmental control technology for grapes resistant to high temperature in summer of the present invention, the atmospheric humidity, soil moisture and light conditions are regulated, and the corresponding foliage fertilizer of the present invention is sprayed. During the whole experiment process, the humidity was controlled between 40-70% through indoor and outdoor ventilation, plastic film covering, under-film irrigation, and drip irrigation. The plants selected for the test have not yet entered the mature stage of coloring, so the soil moisture is controlled at 80% of t...

Abstract

The invention discloses a grape summer high-temperature resistant greenhouse maintenance and management method by humidity regulation. When the maximum temperature of the day reaches or exceeds 35 DEGC, the method for improving the grape plant evapotranspiration capacity by atmospheric relative humidity regulation and soil humidity regulation is adopted to reduce the plant temperature. In addition to sunshade cooling and ventilation cooling, the method also adopts humidity control measures, and measures of applying a grape high-temperature resistant foliar fertilizer at the same time, the humidity control comprises soil humidity and greenhouse air humidity, a control range of the greenhouse air humidity is 40-70%, the composition of the grape high-temperature resistant foliar fertilizer is 50 [mu]mol / L of jasmonic acid, 100 [mu]mol / L of salicylic acid, 10 mmol / L of CaCl2, and 10 mmol / L of ZnSO4. The method reduces the "somatosensory temperature" of grapes by regulating meteorologicalfactors such as temperature, light, humidity, soil moisture and fertilizers in the production of greenhouse grapes, so that the healthy growth of grapes is ensured, the quality and yield of grapes areimproved, and the method has the advantages of low cost, good effect and easy operation, and is suitable for grape production popularization.

Description

technical field [0001] The invention relates to the technical field of viticulture, in particular to a method for maintaining and managing grapes in a high temperature resistant greenhouse in summer through humidity control. Background technique [0002] Grape is the fruit with the largest cultivated area in the world. It is adaptable and easy to reproduce. Grapes are known as one of the four major fruits in the world, with high nutritional value and rich antioxidant components. At the same time, it is also the raw material for the production of various beverages, such as wine. [0003] The management and regulation of temperature is one of the key technologies of protected viticulture. High temperature is a relatively common meteorological disaster. In meteorology, the daily maximum temperature reaches or exceeds 35°C as the high temperature standard. High temperature has a great impact on grapes. It can make grape leaves or a large number of withered and yellowed leave...
