Problems solved by technology

The roots of vegetables need oxygen for respiration to obtain enough energy to absorb the nutrients in the nutrient solution. In the prior art, the floating plate fills the liquid level of the cultivation pond, which reduces the contact area between the nutrient solution and the air, thus making The oxygen content in the nutrient solution is too low

Embodiment 1

[0053] A kind of green leafy vegetable factory floating hydroponic method, such as figure 1 shown, including the following steps:

[0054] A. Make the cultivation pond 11: the cultivation pond 11 is a cuboid as a whole, and one end of the cultivation pond 11 in the length direction is provided with a water outlet 14 positioned at the bottom of the cultivation pond 11, and the other end of the cultivation pond 11 in the length direction is provided with the height of the water outlet 17 Higher than the water pump 15 of the cultivation pool 11, the water inlet end of the water pump 15 is provided with a pipeline 16 communicating with the water outlet 14;

[0055] B. Add nutrient solution 13: add the nutrient solution 13 that provides nutrition to vegetables in the cultivation pond 11, the distance between the liquid level of the nutrient solution 13 and the bottom of the cultivation pond 11 is greater than 15cm;

[0056] C. put into the spoiler: put some spoilers that can sink ...

Embodiment 2

[0075] A factory floating hydroponic method for green leafy vegetables, the difference from Example 1 is that the same floating tray a and floating tray b are placed in the cultivation pool 11, and the floating tray a is located at the side of the floating tray b close to the water outlet 14. side;

[0076] Vegetable a and vegetable b are planted on the floating plate a and the floating plate b respectively, and the maturity period of vegetable a is earlier than that of vegetable b;

[0077] When vegetable a is mature and vegetable b is immature, start the water pump 15;

[0078] Vegetables a are harvested at the water outlet 14, and the floating tray a is taken out from the cultivation pond 11.

[0079] According to the needs of production, different vegetables a and vegetables b are planted, and the floating disk a and the floating disk b are arranged according to the order of vegetable maturity. Since the width of the floating disk is the same as that of the cultivation po...

Embodiment 3

[0084] A factory floating hydroponic method for green leafy vegetables, the difference from Example 2 is that before the vegetables b mature, according to the needs of production, the floating plate c is put into the cultivation pool 11, and the floating plate b is located on the floating plate c The side close to the water outlet 14;

[0085] Vegetable c is planted in the floating tray c, and the maturity period of vegetable b is earlier than that of vegetable c;

[0086] When the vegetable b is mature and the vegetable c is immature, start the water pump 15;

[0087] The vegetable b is harvested at the water outlet 14, and the floating plate b is taken out from the cultivation pond 11.

[0088] When there are immature vegetables in the cultivation pond 11, a new floating tray 12 can be put into the cultivation pond 11 according to production needs, and new different types of vegetables can be planted on the new floating tray 12, and make it close to the outlet. Vegetables ...

Abstract

The invention discloses an industrial floating water cultivation method for green vegetables, and relates to the field of vegetable water cultivation. The method solves the problems that vegetables are not convenient to harvest, a nutrient solution is not uniform, and the oxygen content in the nutrient solution is low. According to the technical scheme, the method is characterized by including thesteps of making a cultivation pond, wherein one end of the cultivation pond is provided with a water outlet, and the other end of the cultivation pond is provided with a water pump communicated withthe water outlet; adding a nutrient solution into the cultivation pond; putting a turbulence part capable of sinking to the bottom of the nutrient solution into the cultivation pond; cultivating vegetables, wherein floating trays with the width equal to the width of the inner wall of the cultivation pond are placed in the cultivation pond, vegetables are planted on the floating tray, the water pump is started once every 8-24 hours, and the duration of the started state of the water pump is larger than 1 hour each time; harvesting the vegetables, wherein the water pump is started, and the vegetables are harvested at the end, near the water outlet, of the cultivation pond. The effects that the vegetables are convenient to harvest, the nutrient substances of the nutrient solution are uniform,and the oxygen content in the nutrient solution is high are achieved.

Description

technical field [0001] The invention relates to the field of hydroponic cultivation of vegetables, in particular to a method for industrialized floating hydroponic cultivation of green leafy vegetables. Background technique [0002] Hydroponic vegetables refer to vegetables whose roots grow in layers of nutrient solution and only provide water, nutrients, and oxygen through nutrient solution, which is different from traditional soil cultivation. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals necessary for the human body. [0003] The Chinese invention patent with the notification number CN102349434B discloses a method for high-yield cultivation of terrestrial water spinach by floating in river water into a lake. The specific technical scheme is as follows: A. Domestication of terrestrial water spinach to aquatic, B. Transplantation, C. Cultivation management, D. harvest. In the present invention, the seeds of terrestrial ...
