Embodiment 1

[0029] Such as Figure 1-2 As shown, the cotton hydroponic device provided in this embodiment includes a culture pot 1 and a pot cover 2 . The culture pot 1 is filled with culture fluid; the pot cover 2 is set on the basin mouth 8 of the culture pot 1; the pot cover 2 is provided with a cotton seedling placement hole 3 and a ventilation hole 4 connected with the culture pot 1, and the placement hole 3 is detachable The ground is inserted with a fixed sleeve 5, and the fixed sleeve 5 is detachably wrapped around the main stem of the cotton seedling 6;

[0030] In the prior art, when transplanting seedlings from the substrate to the nutrient solution, the root system has grown up when transplanting the seedlings, and there are a few lateral roots. The operation process is easy to cause root damage, the seedling recovery period is long, and the stress response caused by root damage will affect the research. result. However, the cotton hydroponic device provided in this embodime...

Embodiment 2

[0033] The difference between this embodiment and embodiment 1 is that a vent pipe 9 is also provided in the vent hole 4 of embodiment 1, the outer end of the vent pipe 9 is connected with an air pump 10, and the inner end of the vent pipe 9 is connected with a vent sand head 11 , the ventilation sand head 11 is set in the culture solution.

[0034] In the prior art, only ventilation holes are provided on the pot cover, and the ventilation holes can only provide less air, which cannot meet the needs of the root system in the nutrient solution. After a long time, it will cause the root system to age and change color. In this embodiment, the method of actively supplementing oxygen is adopted, and the oxygen is transferred to the nutrient solution through the air pump to ensure the oxygen demand of the root system. Avoid aging and discoloration of the root system due to lack of oxygen.

[0035] In practical applications, the material of the fixed cover 5 can be ethylene-vinyl a...

Abstract

The invention discloses a cotton water-cultivating device. The device comprises a cultivation basin, and the cultivation basin is filled with a cultivation solution; a basin cover covers a basin opening of the cultivation basin; the basin cover is provided with a cotton seedling placing hole and a vent hole which are communicated with the cultivation basin, the placing hole is internally detachably provided with a fixed cover in an inserted mode, and a fixed cover detachably covers stems of cotton seedlings; the basin cover is further provided with a crack, and the crack is communicated with the placing hole and the edge of the basin cover. Through the arrangement of the crack, the cotton seedling placing hole is communicated with the edge of the basin cover, the damage of the basin cover to root systems is avoided, the basin cover is provided with the vent hole, the purpose that a nutrition solution is communicated with outside air is guaranteed, oxygen in the nutrition solution can be supplemented, and the problems that the root systems are ageing and discolored due to poor ventilation are solved. The fixed cover used for fixing the cotton seedlings is arranged in the placing hole, and the fixed cover can firmly fix the cotton seedlings to solve the problem that the water-cultivating cotton seedlings are prone to lodging, and further the consistency of the growth of the cotton seedlings is guaranteed.

Description

technical field [0001] The invention relates to the field of plant hydroponic technology, in particular to a cotton hydroponic device. Background technique [0002] Since cotton is a cotyledon unearthed crop, it cannot be directly hydroponics, and it needs to be cultivated in the substrate, and then the cotyledon is unearthed and then transferred to the nutrient solution for cultivation. However, the hydroponics of cotton has the following problems: (1) transplanting seedlings from the substrate into the nutrient solution, the root system has grown up when the seedlings are transplanted, and there are some lateral roots, which may easily cause root damage during the operation. (2) Poor ventilation during hydroponic seedlings often causes aging and discoloration of the root system. (3) Cotton plants are relatively large, and there are often poor fixations in the indoor hydroponics process. After the cotton seedlings grow up, they are prone to lodging and staggering, which af...
