Background technology
The understanding of science, research and grasp be the root growth state of different plants under various conditions, the development of agricultural production is had the directive significance of important science.
At present, agricultural cience and farming techniques personnel mostly adopt existing utensil to replace, and are used to study the growth conditions of different root systems of plant.For example: the growing space of employing Nylon Bag, iron sheet barrel of no end simulation restriction root system, research restriction root system growing space is to the influence of root physiology characteristics such as corn, Chinese sorghum, plant nutrient absorption, output; Adopt overground part Nutrient Absorption, distribution and change of production features such as square case, malthoid paper web research corn, research deep layer root system is nourished and grown to overground part and influence of output or the like.
Though utilize these to replace utensil that the research of plant root growth state is played a role,, exist: the rigidity that has is relatively poor, and no solid shape maybe can't make up the soil tillage pan, effectively the different hardness of simulated soil different soil; Though commonly potted plantly can get complete root system, be subject to the influence of air themperature, hindered growing naturally of root system of plant, damage plant root easily, can't keep the natural integrality of root system of plant; The rigidity that has is better, but but can not cut on request, can't obtain the root system of plant state in the different layerings; Digging pit and get root in the field, is subjected to manpower and condition influence, is unfavorable for the defectives such as practical operation of root system research.Mostly can not study comparatively accurately and measure, influence the reliability and the authenticity of result of study, limit the development of root system of plant research work root system of plant.
The utility model content
The purpose of this utility model is at above-mentioned deficiency, provide a kind of simple in structure, cost is low, easy to use, flexible operation, can simulate the soil horizon hardness in field, keep the root growth and development natural environment, improve the test tube of the research plant root growth state of root system of plant result of study reliability and authenticity.
The technical scheme that realizes the utility model purpose is:
The test tube of this research plant root growth state, characteristics are docked up and down by at least 2 layers of identical shaped test tube connected vertically to be formed, and is connected with ring in the junction of the test tube of different layers.
The cross sectional shape of test tube can be circular, polygon or difformity such as square.Adopt modes such as screw, nut or antithesis buckle to realize flexibly connecting in the junction of ring.
In order to guarantee the root system of plant normal growth, the screw of described test tube, ring, connection ring, nut or antithesis buckle etc. are made by nonmetallic materials such as plastics, lucite.
In order to make ring energy accurate positioning when connecting the test tube of different layers, simultaneously, convenient and strength-saving when using, moving the test tube, be provided with positioning retainer ring or at least 2 positioning retaining strips in each upper edge of testing tube, both play positioning action, played the effect of handle again.
The test barrel structure of this research plant root growth state is simple, can select existing nonmetallic materials and parts for use, and adopts conventional processes to make, and implements easily.
Can be applicable in the research work to plant root growth states such as corn, jowar, soybean, peanuts.Have simple in structure, cost is low, flexible and convenient to use, can simulate the soil horizon hardness of different soils sections such as field soil topsoil and tillage pan, the natural environment that keeps root growth and development, significantly improve the reliability and the authenticity of root system of plant result of study, advantages such as applied range have practical and popularizing value.
