Improved agricultural hydroponics device

Abstract

The invention discloses an improved agricultural hydroponics device which comprises a hydroponics tank, a seal plate and seedling fixing plates. Nutrient solution is stored in the hydroponics tank, the seal plate is fixed into the hydroponics tank, a plurality of mounting holes for arranging the seedling fixing plates are formed in the seal plate, a through hole is formed in each seedling fixing plate, an automatic water supplementing device is further mounted in the hydroponics tank and comprises a solution storage cavity, a solution inlet cavity, a first float ball, a guide rod and a secondfloat ball, the solution storage cavity is fixed onto the seal plate, the solution inlet cavity is fixed to the top of the solution storage cavity, the bottom of the solution inlet cavity is of a hemispherical structure, and a connecting hole is formed in a joint of the solution storage cavity and the bottom of the solution inlet cavity. The improved agricultural hydroponics device has the advantages that the nutrient solution can be automatically supplemented to the hydroponics tank without being manually added, the seedling fixing plates can be ejected by ejection devices after seedlings arecompletely cultivated, accordingly, the improved agricultural hydroponics device is easy to operate, and the time and labor can be saved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an improved agricultural hydroponic device. Background technique [0002] Hydroponics, also known as solution culture, refers to the method of cultivating plants with an aqueous solution containing a certain amount of nutrients needed for plant growth. Compared with the traditional soil seedling cultivation method, hydroponic seedling cultivation has the characteristics of not being restricted by region, time and space, and easy to control the growth environment. It has now developed into a mature plant cultivation method and is widely used in gardening and agricultural production. [0003] A kind of hydroponic device and hydroponic system disclosed in CN206462130U can make the roots of seedlings fully immersed in the nutrient solution of hydroponic box all the time, keep good growth and development, make seedlings avoid lack of nutrition and die, thereby improve the accura...
