Description

High-flux simple rice seedling stage water planting device

Technical Field

The invention relates to the technical field of water culture in a rice seedling stage, in particular to a high-flux simple water culture device in the rice seedling stage.

Background

The stress resistance characteristics of rice in the seedling stage are usually identified by a hydroponic method in a laboratory. For example, in tests for identifying salt tolerance in rice seedling stage, the methods commonly used at present are: firstly, placing rice seeds on a screen mesh fixed in an open container such as a turnover box, and then adding a proper amount of culture solution for culturing; or firstly placing rice seeds in a transparent PCR plate, and then adding a proper amount of culture solution into an open container such as a turnover box and the like to float on the liquid surface for culturing. The method of using the screen mesh is very unfavorable for dynamic observation of root growth, because the screen mesh is fixed, which brings trouble to use, such as placing seeds, supplementing or replacing culture solution, etc. In addition, as the screen mesh is not provided with a space, the efficiency of screening the salt tolerance of multiple varieties is greatly reduced. Although the method using the PCR plate overcomes the above problems, it also creates a number of new problems, such as that the size of the hole in the PCR plate is uniform, and the difference of the sizes of seeds of different varieties is very large, so that some slender seeds cannot be fixed on the PCR plate, and in addition, the manner of putting the seeds into the holes in the PCR plate one by one greatly increases the workload, and the PCR plate is inconvenient to take out one by one when the culture solution is replaced. The water evaporation capacity of the open container is large during culture, so that the salt concentration in the treatment group is easily increased, further, the systematic error is increased, and the experimental result is influenced. In order to ensure consistency of salt concentration, a method of replacing the culture solution at regular intervals (every 1-12 days) is generally used, so that not only is the workload increased, but also a great amount of unnecessary waste is caused.

Detailed Description

As shown in fig. 1 to 13, the present invention mainly comprises a hydroponic tank 1, a seedling tray 2, a screen 3, a spacer 5, a film cover 6 and a fixing rope 7, and is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 4, the hydroponic tank 1 has a rectangular structure with an open top, is made of plastic, and has a light weight while ensuring a certain structural strength. The water planting box can be a transparent piece so as to conveniently observe the growth condition of rice seeds and seedlings in the water planting box. As shown in fig. 5, a pair of partition plates 11 are fixed on the inner wall of the upper middle part of the water planting box, a seedling tray 2 is arranged above the partition plates, and the arrangement of the partition plates can ensure that the seedling tray is always arranged on the upper middle part of the water planting box, so that the seedling tray can be conveniently taken out after the water planting is finished.

As shown in fig. 6 and 7, the seedling tray 2 is a plastic member with a rectangular structure, preferably a transparent member, and a plurality of first elongated slots 22 are arranged on the upper surface of the seedling tray along the transverse direction and the longitudinal direction, and the first elongated slots arranged along the transverse direction and the longitudinal direction form a net structure. The first long grooves which are arranged transversely and longitudinally are arranged vertically in a crossing way, a placement hole 21 is arranged at the intersection of the two first long grooves which are arranged vertically in a crossing way, and the placement hole is a through hole and penetrates through the upper surface and the lower surface of the seedling tray. Each placement hole can accommodate 10-20 rice seeds, handles 23 are respectively fixed on the left and right side walls of the seedling tray, as shown in fig. 7, four insertion holes 24 are arranged at the bottom of the seedling tray, and the four insertion holes are respectively positioned on four vertexes of the rectangle. The seedling tray can also be a foam plate so as to reduce the cost.

The bottom of seedling dish is equipped with screen cloth 3, as shown in fig. 8, and the screen cloth is rectangular shaped plate, is equipped with the aperture 31 that arranges with the matrix form on the screen cloth, is fixed with four inserted bars 32 at the upper surface of screen cloth, and the inserted bar is pegged graft the cooperation with the jack of seedling dish bottom and is realized the installation of screen cloth and seedling dish, and the hole of placing on the seedling dish communicates about the hole on this moment and the screen cloth, and places the hole and correspond with a plurality of apertures.

In use, as shown in fig. 9, the rice seeds are spread on the seedling tray, at this time, part of the rice seeds 4 directly fall into the placement hole, the other part of the rice seeds fall into the first long groove, and the other part of the rice seeds fall onto the upper surface of the seedling tray. And (3) sweeping down the upper surface of the seedling tray and the rice seeds in the first long groove by using a brush, wherein the rice seeds in the first long groove fall into the placing holes. Thus, each placement well is filled with 10-20 rice seeds. Then adding water into the water planting box, placing the seedling tray on the partition board, floating the seedling tray on the water surface, germinating and rooting rice seeds in the placing holes, and allowing the roots of the rice seeds to extend downwards through the small holes.

The open end of the water planting box is provided with a film cover 6, the essence of the film cover is a plastic film, the open end of the water planting box is covered by the film cover when in use, and then the film cover is tied by a fixing rope 7 so as to realize the closing of the open end of the water planting box. For convenient dismantlement and installation, fixed rope can adopt the elasticity rope, covers the film lid behind the open end of water planting case, with fixed rope cover in the open end of water planting case can.

In order to facilitate the placement of rice seeds with different sizes, a spacer is arranged above the seedling tray. As shown in fig. 10, 11 and 12, the spacer 5 is a rectangular plastic member, the spacer is provided with second elongated slots 52 arranged in a crossing manner, and an adjusting hole 51 is arranged at the intersection of the two second elongated slots arranged in each crossing manner, and the adjusting hole is also a through hole and penetrates through the upper and lower surfaces of the spacer. A plurality of parallel cutting strips 53 are arranged at the bottom of the spacer and are in inserted connection with the first long grooves on the seedling tray. During installation, the cutting is inserted into the first long groove to realize the assembly of the seedling tray and the partition pad. After the partition pad is arranged on the seedling tray, the quantity of rice seeds falling into the regulating hole is less than that of rice seeds directly falling into the placing hole.

In order to further facilitate the connection between the screen and the seedling tray, as shown in fig. 13, a slot 25 is provided at the bottom of the seedling tray, and the screen is inserted into the slot during installation.

When the rice seedling tray is used, firstly, the rice seeds are scattered on the seedling tray, then, the excessive rice seeds are swept down from the upper surface of the seedling tray by using a brush and are swept into the placing holes, and at the moment, the rice seeds are all placed in the placing holes and are positioned on the screen; then, adding water into the water planting box, wherein the liquid level in the water planting box is higher than the partition plate by a certain height, and the water adding amount is enough to ensure that the seedling tray still floats on the water surface after the water planting is finished, namely the rice seeds are always contacted with the water in the whole water planting process; then placing the seedling tray on the water surface; the open end of the water planting box is covered by the film cover, and then the film cover and the water planting box are fixed together by the fixing rope.
