Description
Technical Field
The invention belongs to the technical field of seedling culture, and particularly relates to a rice nutrient solution water culture pretreatment cultivation device and a use method thereof.
Background
The rice nutrient solution culture device is widely applied, is a novel soilless culture mode of plants, and is often applied to scientific experiments in laboratories and special seedling pretreatment production, such as pretreatment of rice seeds by soaking in a bactericide, enrichment of medium and trace elements in the seedling stage of rice seedlings, immunity enhancement and the like.
To date, the device of laboratory water planting is when seedling is cultivated and field planting, and traditional way process includes: soaking and sterilizing, accelerating germination of seeds, cultivating and planting germinated seedling seeds and the like. In the seedling cultivation process, the related vessels are more in types; in the process of soaking and accelerating germination, materials such as filter paper, absorbent paper and the like are generally paved on a plate, and clear water needs to be replaced in time to prevent seeds from mildewing and rotting, so that the air permeability is not good enough. The water culture nutrient solution needs to be replaced regularly (3-5 days/time), and the rice is cultivatedEach of which isThe nutrient solution needed in the growth period has different types and concentrations,in thatWhen the nutrient solution is replaced, the nutrient solution is required to be replacedTransferring rice seedlingThe residual nutrient solution in the cultivating device is cleaned, and the process of replacing the nutrient solution is relatively complicatedSimultaneously brings damage risk to rice root system and influences growth and development of rice seedlings. In the process of rice growth, generally, sponge or cotton is selected to wrap the stem of rice, holes are formed in the foam board, the rice is fixed on the foam board, microorganisms such as algae are easy to breed around the sponge and the foam board (in a visible light area), the young stem of the wrapped part of the sponge or cotton cannot see light, crop growth is restricted, in addition, the root system of the rice is easy to damage when the sponge is taken down for monitoring real-time data such as root length, plant height or root secretion, and the like, and possible data distortion is caused. Meanwhile, the water demand of rice seedlings is usually different at different stages along with the increase of the seedling age；Nutrient solution does not need to be supplied at the beginning, and the roots of the seedlings need to be completely soaked in the nutrient solution along with the growth of the rice seedlings, so that the height of the seedlings or the liquid level of the nutrient solution needs to be adjusted according to the growth condition of the seedlings to ensure that the seedlings can absorb nutrients, but the conventional culture device is simple in design and cannot timely adjust the contact height of the rice seedlings and the nutrient solution in the culture device。Generally, after rice germination，Will be transferred to the same size incubation box until moved Planting，And thenThe consumption of the nutrient solution in the early period of the rice is relatively small,and the nutrient solution of the rice seedling needs to be replaced regularly,this may result in excessive waste or incomplete utilization of a large amount of nutrient solution.
Therefore, it is necessary to design a rice nutrient solution culture device which integrates rice seed soaking, sprouting and seedling culture, and is convenient for pretreatment of rice in the early stage and subsequent indoor water culture.
