Description

Sand water culture device for culturing crop seedlings

Technical Field

The utility model relates to a crop cultivation field, concretely relates to combine sand culture water planting advantage for cultivate crop seedling's sand water culture device.

Background

Seedlings such as wheat seedlings, peanut seedlings, corn seedlings and the like are often cultured in a sand culture or water culture manner in laboratories, so as to observe the influence of different culture solutions on the germination of crop seeds and the growth condition of the seedlings.

The sand culture method is a method for culturing flower plants by taking sand, perlite, plastic or other inorganic substances with the diameter of less than 3 mm as a matrix and adding nutrient solution. Can well support the vertical growth of crops, and the crops are easy to root and have no risk of root rot. The defects that the crops absorb nutrient substances and mineral substances slowly and are not sufficient, and the growth is slow; in the test process, the growth condition of the root system needs to be observed, and the sampling of the root system sample or root system secretion is inconvenient.

Hydroponics refers to growing plants without the need for soil. The minerals contained in hydroponic soil are not absorbed by the growth of plants. Hydroponic cultivation is to supply minerals needed for the growth of plants directly through water. However, water is a fluid and has no function of supporting the crops to stand, so that the crops are not easy to normally stand, and the plants can rot due to the lack of oxygen at the roots.

Therefore, the method has respective advantages and disadvantages in sand culture and water culture, and the sand culture is easy to take root and the water culture is easy to rot the root; but the water culture can directly provide nutrients, and the nutrient utilization rate is higher than that of the sand culture. The influence of different culture solutions on the germination of crop seeds and the growth condition of seedlings cannot be observed perfectly by a single crop culture method, and a crop culture device combining a sand culture method and a water culture method is not available in the market at present.
