Description

Technical Field

[0001] This utility model relates to the field of rice breeding technology, and in particular to a device for breeding salt-tolerant rice varieties. Background Technology

[0002] In traditional breeding devices, precise control of salinity and oxygen supply is difficult to achieve. Salinity, a core factor influencing rice salt tolerance, can significantly impact seedling growth and development even with minute changes in its concentration. However, traditional devices often fail to ensure the uniformity and stability of salt solution concentration, leading to variations in salinity environments between different experimental batches or even different locations within the same batch. This results in a lack of comparability and reliability in breeding results. Simultaneously, oxygen supply is crucial for root respiration in rice seedlings, but traditional devices lack effective designs and methods for oxygen supplementation, easily causing root hypoxia, affecting normal seedling growth, and even leading to seedling death, thus interfering with the accurate assessment of salt tolerance traits.

[0003] During seedling transplanting and growth, the roots may rub against or be compressed by the device walls or other components, leading to root damage and affecting their ability to absorb water and nutrients, thus impacting seedling growth and salt tolerance. Traditional devices typically do not provide sufficient growing environment and space for the roots, which not only affects the normal physiological functions of the roots but also limits the seedlings' ability to adapt to salt stress, resulting in selected varieties potentially exhibiting poor salt tolerance in actual saline-alkali soil environments. Utility Model Content

[0004] The purpose of this invention is to provide a salt-tolerant rice variety breeding device that solves the problems of existing technologies in terms of salinity control, oxygen supply, and root protection.

[0006] Preferably, the breeding box has a water inlet at the top, which is connected to a water tank, and a water collection trough at the bottom, with an outlet on the water collection trough.

[0007] Preferably, the water tank includes a clean water tank and a brine tank, and the brine tank is equipped with a stirrer.

[0010] Preferably, the seedling tube is a graduated glass tube.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0024] Example 1

[0025] like Figures 1-2 As shown, this utility model provides a salt-tolerant rice variety breeding device, including a breeding box 1 made of transparent plastic to facilitate observation of the growth of rice seedlings inside. A stepped cultivation plate 2 is installed inside the breeding box 1, dividing the internal space of the breeding box 1 into upper and lower layers. A partition plate 6 is installed in the middle of the cultivation plate 2, dividing the interior of the breeding box 1 into four parts.

[0026] On the upper layer of the cultivation plate 2, two water tanks 3 are placed: a fresh water tank 11 and a brine tank 12. The fresh water tank 11 provides a fresh water environment, while the brine tank 12 provides an aqueous solution environment with a certain salinity. The brine tank 12 is equipped with a stirrer 13, which ensures that the salt solution concentration in the brine tank 12 remains uniform during operation, thereby meeting the requirements for precise salinity control.

[0027] On the lower layer of the cultivation plate 2, several seedling tubes 4 are installed. These seedling tubes 4 are graduated glass tubes to facilitate observation of the root growth of rice seedlings. The seedling tubes 4 are connected to the upper water tank 3 via water inlet pipes 5, forming a liquid circulation system. When it is necessary to provide rice seedlings with aqueous solutions of different salinities, the connection method of the water inlet pipes 5 can be adjusted to select water from the clean water tank 11 or the saline water tank 12.

[0028] like Figure 3 As shown, a support groove 14 is provided inside the seedling tube 4. This support groove 14 provides a stable growth space for the rice seedlings, preventing them from being damaged by shaking or touching during growth. A layer of fine sand 15 is laid below the seedling tube 4. This layer of fine sand 15 simulates the natural soil environment and helps protect the root system of the rice seedlings. In addition, a raised drainage hole 16 is provided at the bottom of the seedling tube 4. The height of the raised drainage hole 16 is greater than the height of the fine sand layer 15, ensuring that liquid can be smoothly discharged during drainage and avoiding water accumulation that may adversely affect the root system.

[0029] To meet the oxygen requirements of rice seedling roots, an aeration pump 7 is installed on the outside of the water tank 3. This aeration pump 7 is connected to the water tank 3 via an oxygen pipe. During operation, the aeration pump 7 can force air into the water tank 3, providing sufficient oxygen to the aqueous solution. The oxygen then enters the seedling tube 4 through the water inlet pipe 5, supplying the rice seedling roots for respiration.

[0030] In addition, a water inlet 8 is provided at the top of the selection chamber 1 to facilitate the addition of water or salt solution to the water tank 3. A water collection tank 9 is provided at the bottom of the selection chamber 1, and a water outlet 10 is provided on the water collection tank 9 to facilitate the discharge of waste liquid in the selection chamber 1. This design simplifies the experimental operation and makes the addition and discharge of liquids more convenient.

[0031] In use, rice seedlings are first planted in the support trough 14 of the seedling tube 4, and the connection method of the inlet pipe 5 is adjusted according to experimental needs to select an appropriate aqueous solution environment. Then, the stirrer 13 and aeration pump 7 are turned on to ensure uniform salt solution concentration and sufficient oxygen supply. During the breeding process, the growth of the rice seedling roots can be monitored by observing the scale on the seedling tube 4, and adjustments can be made as needed. Finally, after the experiment, the waste liquid is discharged through the outlet 10 and the breeding device is cleaned and disinfected for future use.

[0032] Therefore, the above-mentioned salt-tolerant rice variety breeding device has the technical effects of precisely controlling salinity and oxygen supply, protecting the root system from mechanical damage, optimizing liquid circulation and root observation, and simplifying experimental operations. These effects work together in the rice breeding process to improve breeding efficiency and the reliability of breeding results.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
