Embodiment Construction

[0048] A method for diagnosing Chrysanthemum chrysanthemum affected by soil secondary salinization, comprising the following steps:

[0049] Step (1), layered sampling of the soil in the chrysanthemum chrysanthemum planting site, to obtain the collected soil samples;

[0050] Distribute 6 sampling points in the sampling area in an "S" shape, take soil at a depth of 0-10cm, 10-20cm, 20-40cm, 40-60cm, 60-80cm, and 80-100cm, and divide the 6 sampling points at the same depth The soil samples were mixed to obtain the collected soil samples.

[0051] Step (2), Chrysanthemum chrysanthemum sample collection, obtain the collected chrysanthemum chrysanthemum sample;

[0052] Take 2 samples of Chrysanthemum chrysanthemum at each of the 6 "S"-shaped sampling points of soil sample collection;

[0053] Step (3), the measurement of soil electrical conductivity of Chrysanthemum chrysanthemum planting land, conducts conductivity measurement to the soil sample collected in step (1), obtains ...

Abstract

The invention relates to a method for diagnosing soil secondary salinization harm to crowndaisy chrysanthemum. The method comprises the following steps: (1) sampling soil of a crowndaisy chrysanthemumplanting field in a layered manner; (2) collecting a crowndaisy chrysanthemum sample; (3) measuring the conductivity of soil in the crowndaisy chrysanthemum planting field, namely measuring the conductivity of the soil sample collected in step (1); (4) judging the secondary salinization of the soil of the crowndaisy chrysanthemum planting field; (5) determining the influence of secondary salinization on the soil of the crowndaisy chrysanthemum planting field; (6) determining the soil secondary salinization of the crowndaisy chrysanthemum; and (7) evaluating the nitrate content value in the crowndaisy chrysanthemum sample obtained in step (6). The method measures the degree of the soil secondary salinization harm to the crowndaisy chrysanthemum by diagnosing the soil conductivity, the nitrate nitrogen content in the nitrate and the nitrate content in the crowndaisy chrysanthemum, wherein the nitrate nitrogen content in the nitrate and the nitrate content in the crowndaisy chrysanthemumcause the soil secondary salinization and are main components of the soil secondary salinization, and the invention provides a complete, reasonable and feasible diagnosis method.

Description

technical field [0001] The invention relates to a diagnosis method for chrysanthemum chrysanthemum being harmed by soil secondary salinization, which belongs to the field of modern agriculture and can be used for detecting the degree of soil secondary salinization of chrysanthemum chrysanthemum planting land and the damage degree of chrysanthemum chrysanthemum affected by soil secondary salinization. Background technique [0002] In recent years, with the rapid development of my country's facility agriculture, the planting scale of facility vegetable greenhouses has continued to expand. Large-scale protected cultivation and long-term repeated use have resulted in many soil problems, such as soil compaction, soil secondary salinization, soil nutrient imbalance, soil acidification, etc., among which the problem of soil secondary salinization is particularly prominent. [0003] Soil secondary salinization is mainly due to unreasonable fertilization, improper irrigation methods,...
