Description

Plant hydroponics device

Technical Field

The utility model belongs to plant breeding device, concretely relates to plant hydroponics device.

Background

The physiological state of the plant seeds in the germination period and the seedling period is an important factor for determining the good growth of the plants in the later period, and the physiological and biochemical research on the plants in the germination period and the seedling period is a research means and has extremely important significance for the improvement of crop varieties. In some cases, direct planting of seeds in soil is not conducive to research (e.g., research on root development), and plant seedlings must be obtained by hydroponics. In conventional hydroponic tests, the germinated seedlings are often grown on other substrates for some time and placed in hydroponic apparatus, or germinated on moist gauze, filter paper, or seeds are placed directly in nutrient solutions. However, these methods are not versatile and have problems: the roots of the seedlings can be damaged in the transplanting process, and the reliability of research results is influenced; sprouting on gauze and filter paper, on one hand, the roots of seedlings can grow into the gauze or the filter paper, the seedlings cannot be moved in the test process, and on the other hand, the roots cannot be shaded because the roots cannot be stretched in the culture process, so that the growth condition of the roots under natural conditions cannot be simulated; the culture mode of directly placing the seeds in the nutrient solution is only suitable for partial monocotyledonous crops such as wheat, rice and the like, but is not suitable for most dicotyledonous crops such as rape, soybean and cotton, and seedlings of the monocotyledonous crops are difficult to grow normally in the nutrient solution. In addition, when seeds of rape, cotton and the like germinate, the cotyledons can be normally unfolded only by leaving the seed coats in a matrix (such as soil), so that the process is difficult to realize in a matrix-free water culture mode, and the growth state of seedlings is seriously influenced.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: to above-mentioned prior art, this application provides a simple structure practicality, convenient observation measurement root system, the plant hydroponics device of convenient transplantation.

The technical scheme is as follows: the plant water culture device comprises a water tank, a cover plate and a planting cup, wherein the cover plate and the water tank are mutually buckled, and through holes for placing the planting cup are distributed in the cover plate; the planting cup is vertically communicated, and the upper part of the planting cup is provided with a cup edge to be hung on the through hole; the sponge is placed in the planting cup, two pieces of absorbent paper are clamped in the sponge, and the plant seeds are placed between the two pieces of absorbent paper.

According to the method, the plant seeds are placed between two pieces of absorbent paper, the tough absorbent paper is used for limiting the growth of the roots, the roots cannot grow into the sponge, the sponge is taken down if measurement or observation is needed, and the whole roots can be observed by separating the absorbent paper. If the sponge culture is directly adopted, the germinated root hairs can directly grow into the sponge, including the main root and the lateral roots; especially, wheat, rice and the like are fibrous roots, most of the fibrous roots are pricked into the sponge, so that dead angles exist in the observation of roots, particularly the observation of root-stem joints, and indexes such as root physiology, root surface area and the like cannot be measured. Simultaneously, this application still conveniently transplants, directly takes off planting the cup, separates sponge and absorbent paper and can take off complete plant.

In addition, this application apron is the lock with the water tank and links up, makes things convenient for the split, can take out from this and plant the cup and observe, survey etc. single plant, when needing to observe the all plant root system circumstances of contrast, then take out the apron and can realize.

The planting cup is cylindrical, and the diameter of the sponge placed in the planting cup is larger than the inner diameter of the planting cup. Generally, the diameter of the sponge is larger than the inner diameter of the planting cup by more than 0.5cm so as to ensure that the sponge can be kept tightly plugged in the planting cup after absorbing water, and meanwhile, the sponge is utilized to properly extrude seeds so as to realize the function of smoothly dropping off the seed coats when the seeds germinate.

The sponge is formed by splicing two semi-cylinders, and two pieces of absorbent paper are clamped in the middle. The width of the water absorption paper is less than the inner diameter of the planting cup, and the length of the water absorption paper is greater than the depth of the planting cup but less than the depth of the water tank.

This application is in order to avoid the sponge to inhale the poor ventilation of the plant root system that leads to behind the sufficient water, only utilizes the sponge to carry the seed, and the paper that absorbs water goes on through absorbing water, and moisture content is moderate, and the air permeability is good. And the design is suitable for different seed sizes of different plants.

Furthermore, the water tank and the cover plate are made of plastic materials, and the color of the water tank and the cover plate is black or dark.

Preferably, the sponge is as high as the planting cup.

Plant nutrient solution or clear water is filled in the water tank, and the depth is between the lower edge of the water absorption paper and the lower edge of the cylindrical sponge.

Generally, the length, width and height of the water tank are about 50cm, 40cm and 10cm, the diameter of the through hole is 3cm, the depth of the planting cup is 5cm, the inner diameter of the planting cup is slightly smaller than 3cm, the diameter of the cylindrical sponge is 3.5cm, the height of the cylindrical sponge is 5cm, and the width and length of the absorbent paper are 3cm and 9 cm. The size can be adjusted according to the actual situation.

Positions, connection relations and the like which are not mentioned in the application can be realized by any prior art.

Has the advantages that: compared with the prior art, each essential element repeatedly usable of this application device, therefore, the carrier wave prepaid electric energy meter is low in cost, extensively be applicable to monocotyledon crops like the wheat, the rice, maize and dicotyledon crops like the rape, the cabbage, the soybean, the cotton, the seed germination and the seedling growth of various plants such as cucumber, the demand of seedling root system to moisture and air has been taken into account, avoid seedling root to milden and rot, root system can extend naturally in seedling growth early stage, researcher can observe the root system at any time when not damaging the root system, measure, in addition to be like seed that rape and cotton etc. are difficult for taking off the seed coat when sprouting can make the seed coat drop when sprouting effectively, avoid the adverse effect of seed coat to cotyledon extension.
