Description
Technical Field
The utility model belongs to the technical field of the plant cultivation, specifically be an appraisal crop seed is able to bear or endure to flood the device of sprouting and seedling ability of growing that bears flooding.
Background
The flood-resistant improvement of crops is always an important direction for the improvement of crop varieties, the improvement of the flood-resistant characteristic of the germination period and the seedling growth period of crop seeds can improve the survival rate of crops under the stress of flooding, and the planting benefit of farmers is guaranteed. Therefore, the identification of the flooding resistance of the crop seeds in the germination stage and the seedling stage is the key work for improving the variety. And how to accurately, efficiently and conveniently identify the flooding-resistant characteristic is particularly important.
At present, scientific researchers identify flooding resistance of crop seeds and seedlings in two aspects, namely field identification and indoor identification.
The field identification means that the identification material is placed in the natural environment of the field for flooding stress, and the related result is obtained. The general operation is: and sowing the germinated seeds in a field, and performing flooding stress of a corresponding depth after sowing or after seedling growth according to the requirement of flooding identification. However, since field identification is affected by factors such as weather environment, the identification result often has obvious errors, and an accurate and reliable identification result is difficult to obtain.
Most scientific researchers in indoor identification use a test tube or a centrifugal tube as a carrier for identifying the crop flooding capacity. The general operating method is as follows: the seeds are put into a test tube or a centrifugal tube after pregermination, distilled water for identifying the corresponding depth is added, finally, the seeds are put into a set artificial climate box for culture, water is changed in the midway, the relative phenotype and physiological index of the rice seedlings are measured after the time required by identification is reached, the difference of the flooding resistance between different rice is reflected by the indexes, and the required rice material is screened out. However, there are many disadvantages to the identification by test tubes or centrifuge tubes:
firstly, the amount of seeds placed is large and small, the result of the identification of the flooding resistance is influenced, excessive seeds are placed, the insides of the seeds compete with each other, meanwhile, the seeds are extruded after growing out of roots due to the excessive seeds, the seeds climb upwards, the flooding depth in the identification standard has obvious errors, and the identification result is not credible; secondly, if the seeding amount in a single test tube is reduced, the using amount of the test tube is greatly increased, and the workload of the identification process is increased; and thirdly, no matter how many seeds are, with the germination of rice seeds, the root system grows downwards and is damaged due to natural bottom sinking of the seeds, so that the root system grows to be in an unnatural state and the root system lifts up the seeds by 1-3 cm. This also leads to errors in the identification criteria; and fourthly, when the test tube and the centrifuge tube are used, the seeds can be impacted by overlarge water flow when water is changed, so that the root system or the seedling of the seeds are damaged and can be displaced.
