Comprehensive sunshading and cooling device for cress cultivation in summer

Abstract

The invention relates to a comprehensive sunshading and cooling device for cress cultivation in summer, which comprises a cress planting pool, a deep well, a sunshading and cooling shed, a micro nozzle and a water pump, wherein the cress planting pool is in a strip shape and faces to the southeast direction; the deep well is arranged beside the cress planting pool; the sunshading and cooling shed is arranged above the deep well; the frame of the sunshading and cooling shed comprises a phototropic vertical rod, an apheliotropic vertical rod and a longitudinal rod; a sunshading screen is fixed on the phototropic vertical rod; shrinkable and expandable sunshading curtains are arranged on the top and other three surfaces of the shed; the micro nozzle is fixed on the longitudinal rod; and the water pump is used for supplying water in the deep well to the micro nozzle. The device of the invention can be used for comprehensively controlling illumination, temperature, humidity and air permeability in the cress growing process in summer, thereby enabling climatic conditions in the shed frame to be closer to suitable environmental conditions for cress growth, controlling the growth of leaves and stalks of cress, improving the color and the luster of stalks and leaves of cress, controlling the content of crude fibers in stems, enhancing the brittleness of cress, improving the quality and the yield of cress, and enabling the commodity rate of cress to be close to that of cress in winter.

Description

【Technical field】 [0001] The invention relates to an out-of-season cress planting appliance, in particular to a comprehensive sunshade and cooling device for summer cress planting. 【Background technique】 [0002] Cress, also known as Chukui, is a traditional aquatic vegetable variety in my country. The conventional cultivation is sowing or transplanting in autumn and harvesting in winter and spring. With the improvement of people's living standards, the nutritional and health benefits of cress are more and more recognized by people, and the market requires annual production and supply. In recent years, many people are trying to produce annual water celery. During the annual planting process, summer planting of water celery is the most difficult. Planting cress out of season in summer, due to the influence of high ambient temperature and excessive light exposure, the environmental and climatic conditions are difficult to meet the growth requirements of cress, not only the co...
