Description

TECHNICAL FIELD

[0001] The utility model relates to carbon dioxide supplement field, concretely relates to a kind of carbon dioxide supplement device of strawberry planting greenhouse. BACKGROUND

[0002] With the quality demand of agricultural products and the improvement of agricultural planting technology level, the proportion of facility agriculture represented by greenhouse is increasing year by year. The carbon dioxide concentration in the greenhouse is maintained at 100-250 ppm for a long time, which is far from the ideal carbon dioxide concentration (800-1200 ppm) for photosynthesis of plants. This directly affects the photosynthesis of crops and inhibits the growth and development of fruits and vegetables, significantly reducing planting income. Therefore, when strawberries are planted in the greenhouse, carbon dioxide gas needs to be supplemented regularly, and pesticides or nutrient agents need to be sprayed regularly to improve the yield and quality of strawberry planting, shorten the growth cycle and promote agricultural modernization.

[0003] However, the existing carbon dioxide supplement device is generally composed of a carbon dioxide generator and a gas pipeline. The gas pipeline is connected to the output end of the carbon dioxide generator, and the other end of the gas pipeline is placed in the greenhouse. However, when supplementing carbon dioxide gas, it is easy to cause uneven carbon dioxide concentration in different parts of the greenhouse, which affects the uniformity of crop growth in different areas of the greenhouse. At the same time, the gas pipeline cannot be used to spray pesticides or nutrient agents, and other equipment or manual spraying is needed, which is inconvenient to operate.

[0004] Therefore, it is necessary to invent a carbon dioxide supplement device for strawberry planting greenhouse. UTILITY MODEL CONTENT
