High-yield cultivation method for honeysuckle on saline and alkaline land

Abstract

The invention relates to a high-yield cultivation method for honeysuckle on saline and alkaline land. The method includes the key technical steps: selecting 'great mullein' breeds and two-year seedlings; selecting the saline and alkaline land with the salt content of 0.2%-0.3% and pH (potential of hydrogen) of 7.5-8.5; building a drainage system, plowing the land and excavating planting holes; applying 15kg of decayed farm manure and 250g of saline and alkaline land crop compound fertilizers as basic fertilizers in the holes; timely changing soil, planting the honeysuckle and covering black plastic films; reasonably performing pruning and topdressing; comprehensively preventing insect diseases; timely harvesting the honeysuckle; and the like. The honeysuckle is planted on a light saline and alkaline land parcel by the method, so that plants can normally grow and develop, saline and alkaline land resources are sufficiently used, the ecological environment of the saline and alkaline land can be improved, and the land can be improved step by step. Compared with a common planting method, the method has the advantages that the survival rate of the honeysuckle plants reaches 100%, the yield of five-year grown plant medicinal materials is increased by 86.3%, the content of chlorogenic acid and galuteolin is slightly improved and meets 2010 edition standard requirements of China Pharmacopeia, and the method is simple, practicable, easy to operate, remarkable in economic, ecological and social benefit and wide in popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant cultivation methods, and specifically relates to a high-yield cultivation method for honeysuckle in saline-alkali land, which can ensure normal growth and development of honeysuckle plants, improve the yield and quality of honeysuckle medicinal materials, and is of great significance for the development, utilization and improvement of saline-alkali land. Background technique [0002] Saline-alkali land refers to the soil type with a salt content above 0.1% to 0.2%, or soil colloids absorbing a certain amount of exchangeable sodium, and the alkalization degree exceeds 15% to 20%, which is harmful to the normal growth and development of plants. According to statistics from the Food and Agriculture Organization of the United Nations and UNESCO, there are about 1 billion hectares of saline-alkali land in the world 2 , roughly accounting for 10% of the global land area, involving more than 100 ...

AI Technical Summary

Problems solved by technology

Because the unique natural environment of saline-alkali land is very different from ordinary cultivated land, when using ordinary methods to plant honeysuckle on saline-alkali land, not only the growth and development of the plants are slow, but also the plants often die, the yield of medicinal materials is low, and the planting income is not high. Therefore, planting honeysuckle in saline-alkali land has never been successful. Promote it on a large scale
