[Abstract]:Based on the understanding of the basic situation of the study area and the investigation of the local plant species resources, 22 species of vine and tree shrub salt tolerant species were selected for field introduction experiment. By investigating the survival rate and measuring the growth of introduced tree species, the adaptability and growth status of these plants on salt ground were discussed, and the economic and environmental value of these plants were evaluated. The salt-tolerant plants suitable for the growth of the local saline soil environment were screened out, and the propagation methods of several introduced salt-tolerant plants were discussed through cutting and seed potted planting experiments, and the salt tolerance of cuttings and seeds of the tested materials were evaluated. The conclusions are as follows: (1) A total of 65 species of wild plants were found in the coastal area of Cangzhou, belonging to 39 genera of 22 families, including Gramineae, Compositae, Chenopodiaceae, Leguminosae, and herbaceous plants. According to the different saline soil environment and plant dominant species, the plant communities in the study area can be divided into strong salt tolerant plant community-Suaeda salsa community, moderate salt tolerance community-bicolor community. And the light salt tolerant community including Reed community and weed plant community. Among them, three kinds of plants, such as Suaeda bicolor, Suaeda salsa and watermelon seedling, all have some ornamental and medicinal value, and have high value of development and popularization. (2) the survival rate of 22 salt-tolerant plants introduced in the field was studied. Through comprehensive investigation and measurement of growth and growth status, 12 introduced plants with certain salt tolerance were selected. Among them, Lagerstroemia, Acacia, and Lycium barbarum have good growth and high adaptability. The survival rate of the plants with the highest survival rate is 100. The survival rate of fast-growing white wax, privet, mulberry and Luan trees has also reached more than 85%; secondly, the survival rate of aspen, torch wood, hibiscus, The survival rate of common white wax was also relatively high, and the survival rate was between 67.5% and 70%. (3) three kinds of salt-tolerant plants with better adaptability to soil environment were used in cutting experiment. The experiment consists of 0. 0. 21 and 0. 30 and 0. 42 and 0. 53, 5 treatments with different salt contents. In the course of the experiment, the survival rate and growth of the cuttings were investigated and counted. After the experiment, the number of rooting of the cuttings was counted and the inhibition rate was calculated. It is concluded that the salt tolerance of each plant can be changed from strong to weak, and the leaf of Lycium barbarum L. with five leaves is Lagerstroemia chinensis. The survival rate of the cuttings was 80 when the salt content was 0.21, and the survival rate was 87% and 73% in the soil with 0.21% salt content, respectively. The survival rate of Lycium barbarum was about 0.40% in the soil. The survival rate can reach 90%. (4) seed planting experiment was conducted with three kinds of seeds of Lagerstroemia chinensis, Artemisia pentaulata and Albopsis acacia as experimental materials. Through the analysis of seedling emergence rate, relative salt damage rate and other salt tolerance indexes of plant seeds, it was found that all three plant seeds had salt tolerance to a certain extent. The emergence rate of three plant seeds of Lagerstroemia rugosa, Acacia pentaulata and Acacia acacia was the highest among the three plant seeds when the salt content in soil was 0.21, respectively, and the seed emergence rate was: 1. 78%, 87. 775 and 75. 75%, among the three kinds of plant seeds, Albizia amurensis seeds had the strongest salt tolerance.
