Method for cultivating potted anthurium under condition of subtropical zone dry-hot valley climate

Abstract

The invention discloses a method for cultivating potted anthurium under the condition of the subtropical zone dry-hot valley climate. By means of the method, temperature reduction and humidification are carried out at the same time. The potted anthurium is cultivated in a greenhouse. The environment parameter in the greenhouse is controlled in the mode of illumination control and temperature reduction and humidification control, wherein according to the illumination control, when illumination intensity exceeds 18000Lux, a black sunshade net at the outer layer of the greenhouse is unfolded for shading, and if the illumination intensity still exceeds 18000Lux, a silver sunshade net at the inner layer of the greenhouse is started for supplementing shading and meeting the illumination requirement; according to the temperature reduction and humidification control, when the indoor temperature in the day is higher than 27 DEG C, a water screen draught fan system is adopted for temperature reduction and humidification, namely a water pump is utilized for supplying water to a water screen in the greenhouse, an axial flow draught fan drives air to enter the greenhouse and pass through the water curtain, heat exchange is carried out between the air entering the greenhouse and water, and the humidification of the air entering the greenhouse increases, and when the indoor day and night temperature is below 17 DEG C, a hot-water pipeline laid at the bottom of a seedbed emits heat for increasing the temperature.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a method for cultivating potted anthurium flowers under subtropical hot and dry valley climate conditions. Background technique [0002] Panzhihua is a high-altitude, low-latitude, plateau-type inland mountain "island-like" south subtropical three-dimensional climate type, and it is a natural large greenhouse. The microclimate is complex and diverse, with rich heat, sufficient sunlight, small annual temperature range, large diurnal range, distinct dry and rainy seasons, no obvious distinction between four seasons, and obvious vertical climate differences; Large, warm and early spring, vigorous evaporation, no extreme heat in summer, concentrated rainfall, frequent night rain, cool autumn and less rain, and no severe cold in winter. [0003] Anthurium is native to tropical and subtropical forests of Central and South America. It likes a warm, humid and semi-shady environment, b...

At the same time, the humidity in the greenhouse is also low. The traditional method of spraying water for humidification needs to consume a lot of water resources, and the air flow in the greenhouse is small, the effect of humidification is not obvious, and it will also cause water accumulation in the greenhouse.
