Indoor culturing device for corn variety barren tolerance research

Abstract

The invention belongs to the technical field of plant experiment devices, in particular to an indoor culturing device for corn variety barren tolerance research. The indoor culturing device comprisesa culturing tank, wherein culture medium earth for planting corn is stuffed and placed in the culturing tank; a plurality of feeding inserting pipes are arranged on the outer side walls of the culturing tank; and one end of each feeding inserting pipe penetrates through the culturing tank to be inserted into the inner part of the culture medium earth. Through the adoption of the indoor culturing device disclosed by the invention, the culturing tank which is placed indoors is arranged, and a plurality of the feeding inserting pipes are uniformly arranged on the side walls of the culturing tank,so that wastes can be uniformly transported to the culture medium earth; the corn can be planted indoors, the external environment factors relevant to the growth of the corn can be controlled to be consistent, and only the factor of the fertility of fertilizers required by the corn is changed, so that the influence of natural environment on the growth of the corn is reduced, and more accurate growth situation is obtained; and in the indoor environment, time of researchers for running to an experiment site can be reduced, and the testing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of plant experiment devices, and in particular relates to an indoor cultivation device for studying the barren resistance of corn varieties. Background technique [0002] The low content of nutrient elements in the soil, coupled with insufficient fertilization, will lead to a reduction in corn yields, especially in areas with complex and diverse natural conditions and backward economic conditions. Insufficient input is an important reason to limit the increase of corn yield. In economically developed areas, the increase in the amount of chemical fertilizer application has increased the yield of corn. However, a large amount of chemical fertilizer input will cause serious environmental problems. In addition, the relationship between chemical fertilizers and corn The price comparison is also high. Therefore, it is necessary to find a method that can solve the problem of yield reduction caused by insufficient n...

[0002] The low content of nutrient elements in the soil, coupled with insufficient fertilization, will lead to a reduction in corn yields, especially in areas with complex and diverse natural conditions and backward economic conditions. Insufficient input is an important reason to limit the increase of corn yield. In economically developed areas, the increase in the amount of chemical fertilizer application has increased the yield of corn. However, a large amount of chemical fertilizer input will cause serious environmental problems. In addition, the relationship between chemical fertilizers and corn The price comparison is also high. Therefore, it is necessary to find a method that can solve the problem of yield reduction caused by insufficient nutrients without increasing the input of chemical fertilizers, that is, to increase the utilization rate of chemical fertilizers. There are significant genetic differences in transportation, transformation and utilization, which provides a good opportunity for the use of breeding methods to solve the problem of nutrient deficiency, that is, the selection of barren-tolerant maize varieties

[0003] At present, the breeding work for barren-tolerant maize varieties is basically in the outdoor environment, and two or more groups of maize species are planted on natural land with different fertility. However, the conditions that affect the growth of maize in the natural environment include insect pests, There are many factors such as environmental temperature and humidity, land temperature and humidity, and land fertility. In the natural environment, it is difficult to determine other environmental factors, only the impact of land fertility on corn plants, and there are other uncontrollable factors. Therefore, there is an urgent need for a Indoor cultivation device for research on barren resistance of maize varieties
