Plant growing experiment apparatus

Abstract

The invention discloses a plant growing experiment apparatus. The plant growing experiment apparatus is provided aiming at the fact that currently there is no special experiment equipment to carry out corresponding experiments for biology experiments in elementary and secondary schools, and is used for carrying out experiments of experimental structures of growth influence on plants of lights of different wave bands, experimental structures of growth influence on the plants of different microelements, phototropism experimental structures and the like in elementary and secondary schools; six different sets of nutrient solution grooves are formed in the plant growing experiment apparatus, when the same light is collocated, six schemes of lacking iron, calcium, potassium, sodium, phosphorus and the like are adopted in the six sets of nutrient solution grooves respectively, and on the premise that other environmental conditions are consistent, the growth difference of the same plant when lacking the different microelements is observed; six different growth groups are designed in the plant growing experiment apparatus, light sources are ultraviolet rays of 370 nanometers, blue rays of 450 nanometers respectively, the blue rays and red rays of 660 nanometers are combined with a ratio of 1:1, the red rays of 660 nanometers, green rays of 530 nanometers and infrared rays of 850 nanometers carry put a supplementary lighting experiment for the plants, and the plant growth difference under different types of illumination can be observed.

Description

technical field [0001] The invention relates to the field of educational experiment instruments and equipment for primary and secondary schools, in particular to a plant growth experiment instrument. Background technique [0002] Now primary and secondary education focuses on quality education. From the third grade of primary school to the third grade of high school, there are many contents about plants in the natural science class, for example, the phototropism of plants, and the growth of plants by lights of different bands (colors). The effect of different trace elements on the growth of plants, etc. However, so far there is no special experimental equipment to carry out corresponding experiments, and the teaching process is carried out by "looking at pictures and talking". [0003] With the improvement of teaching requirements, parents and schools have higher requirements for children's quality teaching, and there is an urgent need for a teaching instrument that can car...
