Method for judging salt damage grade of bamboo plants

Abstract

The invention relates to a method for judging the salt damage grade of bamboo plants, and relates to bamboo plants. The method for judging the salt damage grade of the bamboo plants comprises the steps that materials are prepared as the following requirements, specifically, in a nursery, bamboo seedlings are buried and potted, plastic pots are filled with nutritious soil, the bamboo seedlings arepoured with water, when all bamboo are survived and then moved into a shed, and the pot bamboo is selected as the experimental materials; the requirements of soil salinization gradient are as follows,specifically, six salinity levels are arranged, wherein the three salinity levels repeat, and the six salinity levels comprises tap water, 0.1% of a NaCl aqueous solution, 0.3% of a NaCl aqueous solution, 0.5% of a NaCl aqueous solution, 0.7% of a NaCl aqueous solution and 1.0% of a NaCl aqueous solution; the time of soil salinization treatment is as follows, specifically, during the cultivationprocess of the potted bamboo, the NaCl aqueous solution is poured in the bamboo seedlings for every 3-5 days to maintain the soil salt concentration of each treatment, and salt treatment is stopped when most of leaf tips and leaf edges turned yellow of the tested bamboo to leaves; and the salt tolerance grade is determined by sampling and analysis. The method for judging the salt damage grade of the bamboo plants can accurately determine the salt damage grade of the bamboo plants.

Description

technical field [0001] The invention relates to bamboo plants, in particular to a method for judging the salt damage level of bamboo plants. Background technique [0002] Soil salinization is one of the important environmental problems that threaten ecological security and human survival, and it is a serious problem that affects agricultural and forestry production and the ecological environment. my country's existing saline soil area is about 2.7×10 7 hm2, accounting for almost 1 / 3 of the country's land area, are distributed in the eastern coastal areas, northeast and northwest inland regions. The development and utilization of such a large area of ​​saline-alkali land will not only help to increase the available land resources for agriculture in our country and alleviate the shortage of agricultural land in our country, but also greatly improve the ecological environment, increase green vegetation, and increase forest coverage. [0003] Bamboo plants are an important par...

Problems solved by technology

[0004] Current problems: There are generally two reasons for the scorch phenomenon of bamboo leaves, one is caused by diseases such as salt damage, and the other is physiological disease symptoms caused by potassium deficiency, which must be correctly distinguished
