Embodiment

[0024] In order to make the purpose of the present invention and the technical scheme clearer, the present invention uses specific examples to carry out the research and screening process of the selection of treatment plants, the concentration selection of treatment medicaments, the composition of treatment medicaments, the dosage and frequency of medicament spraying, etc. Sufficient description is given to prove the correctness of the research results, but it does not mean that the present invention is limited to these examples.

[0025] 1) Selection of treatment plants

[0026] This embodiment selects the safflower loropetalum in the campus of Kunming University as the experimental material. According to the growth status of the test material, it is divided into three types: healthy tree, vigorous tree, healthy tree, medium tree, basically healthy tree, and vigorous tree. Weak, unhealthy tree body and weak tree vigor, all selected test materials were artificially sprayed wit...

Abstract

The invention discloses a chemical and a method for reducing damage and improving ornamental value of loropetalum chinense under acid rain stress. The chemical includes: 0.4-1.6 mmol / L salicylic acid, 0.4-1.6 mol / L sodium nitroprusside and 12-48 mmol / L calcium nitrate. The invention solves the problem in the prior art that no method for effectively alleviating the harm of acid rain to the loropetalum chinense exists. By the adoption of the chemical and method, in urban landscapes in areas with serious acid rain harm, leaves of the loropetalum chinense are not or rarely damaged, few leaves become yellow, and dry, and fall off, leaves are not atrophied or deformed, chlorophyll, cyanin and flavonoids are basically stable, and leaf color still maintains the original bright red or dark red or other colors without obvious leaf color change visually, so that the loropetalum chinense still maintains a higher ornamental value.

Description

technical field [0001] The invention relates to the technical field of horticultural plant protection, in particular to a medicament and a method for alleviating damage to Loropetalum safflower and improving ornamental performance under acid rain stress. Background technique [0002] Loropetalum safflower is native to my country, and it is an evergreen shrub of Hamameliaceae, Loropetalum genus, and Variety of Loropetalum genus. It has luxuriant branches and leaves, graceful posture, resistant to pruning and pinching, and when the flowers bloom, the tree is full of red flowers, which is extremely spectacular. The new leaves of P. safflower are bright red, and the leaf color of mature leaves varies from dark green to dark red. In various cities south of the Yangtze River in my country, P. safflower has become an indispensable tree species for gardening , can be used for cluster planting as color fence, group planting as color blocks, molded flower beds, isolated planting as co...
