Description

Technical Field

[0001] The utility model relates to a water-fertilizer applicator, in particular to a water-fertilizer quantitative applicator for deep liquid flow cultivation, belonging to the technical field of water-fertilizer applicators. Background Art

[0002] Deep liquid flow cultivation technology refers to immersing most of the roots of leafy vegetables in a culture solution with a deeper liquid layer. Since leafy vegetables need to continuously absorb nutrients during the growth process, a fertilizer applicator is needed to fertilize the leafy vegetables. In order to improve the nutrient absorption effect of leafy vegetables, water fertilizer is usually applied to the leafy vegetables. Water fertilizer refers to dissolving the fertilizer in a certain proportion of water and then applying it to the culture solution of the leafy vegetables.

[0003] According to a fertilizer applicator for deep liquid flow cultivation of leafy vegetables disclosed in patent No. CN220776894U, the fertilizer applicator can push leafy vegetable branches or other debris accidentally dropped at the bottom of the planting trough to the bottom of the suction frame and extract them for cleaning, thereby avoiding the situation that most of the leafy vegetable branches or other debris at the bottom of the existing planting trough cannot be cleaned by the fertilizer applicator, resulting in poor quality of the nutrient solution. The quality of the nutrient solution for circulating fertilization is guaranteed by timely cleaning the leafy vegetable branches and other debris at the bottom of the planting trough, thereby ensuring the growth quality of the leafy vegetables.

[0004] However, in the technical solution of the above patent, since it does not have a stirring function, the dissolution rate of fertilizer and water is low, and the fertilizer may even be deposited in the water, resulting in insufficient nutrients in the applied water and fertilizer, thereby affecting the growth of leafy vegetables. At the same time, after cultivating a crop of leafy vegetables, people need to remove the culture plate and clean it. However, in the prior art, it is inconvenient for people to disassemble the culture plate, which makes people disassemble the culture plate at a low rate. Utility Model Content
