Forestry soilless seedling raising equipment

Abstract

The forestry soilless seedling raising equipment comprises a primary nutrient solution tank, a circulating device is arranged at one end of the interior of the primary nutrient solution tank, a first electric push rod is fixedly connected to one side of one end of the interior of the primary nutrient solution tank, and a movable ball is movably connected to one end of the first electric push rod; one end of the movable ball is movably connected with a push plate, one end of one side of the push plate is provided with a hemispherical groove, the nutrient solution rises from the other end of the nutrient solution circulating pool to a first circulating through hole and flows into the other end of the primary nutrient solution groove, and at the moment, a first electric push rod and a second electric push rod move backwards; the first electric push rod drives the push plate to vertically move to the other end of the primary nutrient solution tank, so that the flowing intensity of the nutrient solution is reduced, the nutrient solution circularly flows in the primary nutrient solution tank and the nutrient solution circulating pool, oxygen in the nutrient solution is increased, and the cost of traditional soilless seedling raising equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of soilless seedling cultivation, in particular to a forestry soilless seedling cultivation equipment. Background technique [0002] Soilless seedling cultivation is a new technology used in modern plant cultivation. Instead of using soil, the nutrients needed by plants are made into culture fluid to cultivate plants. The advantages of soilless seedling cultivation are that the seedlings grow rapidly, the seedling age is short, and the root system The growth is good, the seedlings are strong and neat, and the seedling time is short after planting, and they are easy to survive. Whether it is substrate seedling cultivation or nutrient solution cultivation, sufficient water and nutrient supply can be ensured, and substrate ventilation is good. At the same time, soilless seedling cultivation is convenient for scientific and standardized management. [0003] The deficiencies of the prior art: one: in order to e...

AI Technical Summary

Problems solved by technology

[0003] The deficiencies of the prior art: one: in order to ensure sufficient oxygen in the nutrient solution, the traditional soilless seedling raising equipment for forestry seedlings is usually oxygenated by an oxygen pump, and the cost is relatively high. When the soilless seedling raising equipment is in use, the nutrient solution needs to be replenished regularly, and the nutrient solution cannot be replenished when the concentration of the nutrient solution is low. The traditional soilless seedling raising equipment cannot adjust the height of the forest seedling fixing frame according to the growth length of the forest seedlings. Therefore, there is an urgent need for a forestry soilless seedling raising equipment
