Water planting method for Chinese pine seeding suitable for experiment

Abstract

The invention discloses a water planting method for a Chinese pine seedling suitable for an experiment. The water planting method comprises the following steps: A. seed germination pre-cultivation, namely Chinese pine seeds are disinfected with 0.1% mercuric chloride, washed by running water for further use, clean wet sand is loaded in a cultivating device, and germination pre-cavitation of the Chinese pine seeds is conducted in general sand, B. adaptability cultivation, namely after the seeds are germinated, same-size and robust seedlings are chosen and transplanted into water for adaptability cultivation till seed cases drop off, C. growth of needles, namely after the seed cases drop off, the seedlings are transplanted to nutrient solution to cultivate, and two-wheeled needles grow after twenty days, and D. seedling collection, namely seedlings are collected according to experiment requests to be used in the experiment. The water planting method for the Chinese pine seeding suitable for the experiment has the advantages that soil is replaced by the nutrient solution to cultivate Chinese pine seedlings trough seed germination to Chinese pine growth, thus control and operation are easy, the growth of the Chinese pine seedlings is faster than soil culture, the growth of the Chinese pine seedlings is good, good seedlings are provided to the experiment, when the roots of the seedlings are under stress treatment, other factors of experimental treatment is controllable, the factor is single and strong in controllability, the Chinese pine seedlings are suitable for process of the experiment, and accuracy of experiment data is improved.

Description

technical field [0001] The invention relates to a hydroponic method for Chinese pine seedlings, in particular to a hydroponic method for Chinese pine seedlings suitable for experiments. Background technique [0002] Pinus tabulaeformis is a kind of woody plant. As the experimental material, it mainly grows in soil. Due to the complex composition of the soil, it is easy to carry pathogens and easily cause damping-off of pinus tabulaeformis. When the soil is cultivated, there are rotten roots, but the leaves are not obvious, so It may not be credible in the short term to judge the quality of seedlings only by observing the condition of leaves during previous experiments. During the experiment, it is difficult to deal with the stress of the seedling root system, and due to the characteristics of the soil, the accuracy of the control treatment is not strong, which seriously affects the accuracy and reliability of the experimental data; in addition, it is difficult to measure the...

[0002] Pinus tabulaeformis is a kind of woody plant. As the experimental material, it mainly grows in soil. Due to the complex composition of the soil, it is easy to carry pathogens and easily cause damping-off of pinus tabulaeformis. When the soil is cultivated, there are rotten roots, but the leaves are not obvious, so In the previous experiments, only the condition of the leaves can be observed to judge the quality of the seedlings, which may not be credible in the short term

During the experiment, it is difficult to deal with the stress of the seedling root system, and due to the characteristics of the soil, the accuracy of the control treatment is not strong, which seriously affects the accuracy and reliability of the experimental data; in addition, it is difficult to measure the physiological indicators related to the root , It is easy to damage the roots when taking seedlings with soil or perlite as the substrate, and it needs to consume a lot of labor
