Efficient tea tree nutrient bioavailability evaluation method and device

Abstract

The invention discloses an efficient tea tree nutrient bioavailability evaluation method and device. The device is characterized in that a plurality of partitions are fixedly arranged inside a shell in an equal distance manner, the partitions separate the interior of the shell into multiple planting areas, a plurality of planting containers are distributed in each planting area in an equal distance manner, each planting container is of a conical structure, the diameter of the bottom of each planting container is smaller than that of the top of the planting container, a water collecting container is arranged at the bottom of each planting container, each planting container is arranged at the top of the corresponding water collecting container, the bottom of each planting container is provided with draining holes communicated with the corresponding water collecting container, and a water circulating mechanism is connected to the outer side of each water collecting container. The efficient tea tree nutrient bioavailability evaluation device has the advantages that water, which is not absorbed by soil, in the planting container can enter the water collecting containers through the draining holes and be conveyed into the planting containers through the water circulating mechanisms, and accordingly nutrient waste is prevented, and obtained test data is accurate.

Description

technical field [0001] The invention relates to the technical field of tea tree seedling cultivation, in particular to a highly efficient method and device for evaluating the biological effectiveness of tea tree nutrients. Background technique [0002] When tea trees are growing seedlings, it is necessary to test the utilization rate of nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur to determine the most suitable growth environment for tea trees. Most of the current planting containers are equipped with ventilation holes at the bottom to facilitate the cultivation of tea trees. The outside air enters the soil, which is beneficial to the growth of the roots of tea trees. However, since the nutrients in the soil will dissolve in the water body and follow the water body to lose from the air holes, the content of the nutrients in the soil will decrease, which will affect the test results. Big margin of error. To this end, we propose an efficie...
