Hormone spraying device for rice physiological research

Abstract

The invention discloses a hormone spraying device for rice physiological research, and belongs to the field of rice physiological tests, the hormone spraying device comprises a ground, rice is planted on the ground, an outer pipe is fixedly mounted in the middle of the rice on the ground, a telescopic inner pipe movably sleeves the middle of the outer pipe, and a horizontal spray head is fixedly connected to the top end of the telescopic inner pipe. Spraying openings are formed in the two ends of the horizontal spraying head, a sliding piston is fixedly connected to the bottom end of the telescopic inner pipe, and a pushing and lifting spring is fixedly installed at the bottom end of the sliding piston. The orderly change of the height of the horizontal spray head is realized by arranging the outer pipe and the telescopic inner pipe for combined stretching and retracting, and the change of the heat production value of the electric heating wire is regulated according to different capacities of rice leaf shielding on the arc-shaped solar panel, so that the air pressure in the air chamber is further controlled; and finally, the tested rice plant meets the saturated adsorption of the leaf on the hormone liquid with the tested concentration in different growth periods and different weather conditions, so that the quantitative controllability of the hormone test is ensured.

Description

technical field [0001] The invention relates to the technical field of rice physiology test, in particular to a hormone spraying device for rice physiology research. Background technique [0002] Plant hormones are signal molecules necessary for higher plants to sense changes in the external environment, regulate their own growth state to resist adverse environments and maintain survival. It is of great significance to increase grain yield and develop harmless agriculture by spraying corresponding hormones in the process of cultivation. The application tests of various rice hormones have shown their important beneficial effects on rice, so the hormone test research is of great significance to rice research and field production guidance. In recent years, the systematic research of new hormones that have been discovered and the emergence of new hormone products all require agricultural researchers to conduct a large number of long-term supporting field research experiments. ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing rice hormone spraying device proposed in the background technology, the present invention provides a hormone spraying device for rice physiological research, which is equipped with automatic adjustment of spraying height, timing and quantitative spraying, and automatic rainy day. Advantages such as stop spraying, solve the technical problems such as labor-intensive and large subjective error when the existing spraying device proposed in the above-mentioned background technology to deal with low seedlings, spraying time and spraying amount only rely on experience, etc.
