Soilless culture device for peanuts in full growth period

Abstract

The invention belongs to the field of agriculture and relates to a soilless culture device for peanuts in the full growth period. The device comprises a nutrient solution storage tank, detachable moving devices, an air pump, a ventilation pipeline, an air inlet pipe with a valve, and a drainage pipe with a valve; wherein the nutrient solution storage box is a box body with a top opening, the top opening of the nutrient solution storage box is covered with a plurality of detachable moving devices arrayed closely and horizontally, each detachable moving device adopts a groove structure, a plurality of hollow column bodies are arranged in the groove structures, the hollow column bodies are communicated with the bottoms of the groove structures, the air inlet pipe with the valve and the drainage pipe with the valve are respectively communicated with the side wall of the lower end of the nutrient solution storage tank, and the air inlet pipe with the valve is connected with the air pump through the ventilation pipeline. The device can be used for observing the growth of root systems of the peanuts conveniently and the partial growth of the root systems and fruits, so as to apply a soilless cultivation technology in cultivation of the peanuts in the full growth period. Meanwhile, the device has the characteristic that a nutrient solution is convenient to ventilate and convenient to replace.

Description

Technical field [0001] The invention belongs to the field of agriculture, and relates to a device for cultivating peanuts, in particular to a soilless cultivating device during the whole growth period of peanuts. Background technique [0002] In soilless cultivation, artificially prepared culture fluid is used to supply the needs of plant mineral nutrients. Soilless culture is a cultivation technique that does not use natural soil but uses nutrient solutions containing essential elements for plant growth and development to provide nutrients, so that plants can complete the entire life cycle normally. In soilless cultivation technology, whether a nutrient solution with a coordinated ratio and an appropriate concentration can be provided for plants is the key to successful cultivation. In order to make the plant stand upright, quartz sand, vermiculite, peat, sawdust, plastic, etc. can be used as supporting media, and the root system can be kept aerated. Years of practice has prov...

AI Technical Summary

Problems solved by technology

[0003] For peanuts, due to the special propagation method of peanuts, that is, flowering on the ground and fruiting underground, soilless cultivation techniques are almost used to cultivate peanuts. At present, the existing technology only uses soilless cultivation techniques in the peanut seedling stage. For peanuts The soilless culture technology of the whole growth period is still in a blank stage

In addition, in the existing soilless cultivation technology, the nutrient solution is often hypoxic due to lack of ventilation, which seriously affects the growth of the root system, and the seedlings are prone to tilting, which seriously affects the quality control of cultivation.
