Problems solved by technology

[0007] In order to solve the technical problem of using the same species of plants to absorb the eutrophic elements in the water body to purify the water body, the technical problem of which plant configuration mode to adopt has a more competitive absorption relationship with the nutrients in the culture medium is ignored, the invention provides a hydroponic Method for determining the competition relationship of nutrients in the same plant under different conditions

Embodiment Construction

[0037] Combine below Figure 1-Figure 4 , introduce the method of the present invention in detail. The method for measuring the nutrient competition relationship of the same plant under the hydroponic condition of the present invention is to carry out the following test 1 and test 2 simultaneously:

[0038] (1) Test 1:

[0039] 1. Select two plants with small individual differences from the same plant for hydroponics. The two selected plants come from different mother plants, one of which comes from mother plant A, and the other plant comes from mother plant B. The judging parameters for plants with small individual differences between the two plants are: the difference between the total leaf area of ​​the two plants ≤ 5mm 2 , the difference in plant height between two plants is ≤10mm, and the difference in main stem thickness between two plants is ≤1mm;

[0040] II. Insert a seedling tray 4 into each of the two planting cups 5 of the incubator 1 of the device for measuring...

Abstract

Disclosed is a method for measuring nutrient competition of the kindred plants under water planting. By the method, an experiment 1 and an experiment 2 are performed at the same time. The experiment 1 is performed by selecting a stock plant A and a stock plant B of the kindred plant to be cultivated in a kindred-plant nutrient competition measuring device under water planting. Different from the experiment 1, the experiment 2 selects two plants from the stock plant A. The method includes calculating competition intensity index of non-relative plants for nutrients in the water by the measured nutrient content of the stock plants, if the index is larger than zero, determining that the kindred plants have nutrient absorption competition relation, and selecting the distribution mode of the non-relative plants when the water is purified by hydroponic plants; otherwise, selecting the distribution mode of the relative plants; if the index is equal to zero, selecting any one of the distribution modes. The method can conveniently determine the competition relation among the non-relative modes and can select the advantageous plant distribution mode having good nutrient absorption effect in the water to be applied to water purification in the water ecological restoration.

Description

technical field [0001] The invention relates to a device for measuring nutrient competition relationship among plants of the same species under hydroponic conditions, and belongs to the technical field of water ecological restoration. Background technique [0002] At present, building and restoring water ecology is a low-cost and effective water ecological restoration method in the eutrophication control measures, absorbing and removing eutrophic elements in water through aquatic plants or plants suitable for hydroponics. The general hydroponics method is to put the same kind of plants in the water body for cultivation, and remove the nutrients in the water through the absorption of nutrients in the water by the plants during the growth period. The same plant refers to plants of the same species. [0003] However, in the process of hydroponic cultivation of the same species of plants, the research on the special ecological functions of plants in the water environment is ign...
