Method for planting selenium-enriched jasmine flower

Abstract

The invention discloses a method for planting selenium-enriched jasmine flowers. The method comprises the following steps: 1) preparing cuttage seedlings, namely cutting jasmine flower twigs longer than one year as cuttage seedlings, by taking cut ends as inclined surfaces, inserting the cut ends of the cuttage seedlings into a nutrient solution, performing water culture, and after roots grow out, transplanting into a planting field; and 2) performing planting field treatment, namely applying a heavy metal chelation liquid into the planting field, covering the planting field with a preservative membrane, introducing earthworms, continuously covering the planting field with a preservative membrane, turning over soil to remove earthworms, applying a farmyard fertilizer, uniformly mixing with planting field soil, adjusting the humidity of the planting field to 45-50%, and transplanting the jasmine flower cuttage seedlings treated in the step 1) into the planting field. By adopting the method, the selenium-enriched jasmine flower cuttage seedlings are firstly cultured, the planting soil is secondly treated with the heavy metal chelation liquid, then heavy metals of the jasmine flower planting field do not exceed standards, furthermore as the farmyard fertilizer is adopted as a base fertilizer, rapid growth of the jasmine flowers can be promoted, the selenium content and the yield of the jasmine flowers can be remarkably increased, and the quality of the jasmine flowers can be improved.

Description

technical field [0001] The invention relates to the technical field of jasmine planting, in particular to a planting method of selenium-enriched jasmine.

Problems solved by technology

With the development of the economy, in recent years, with the continuous improvement of people's quality of life, people's demand for jasmine tea is constantly increasing and its quality requirements are also constantly improving, requiring green environmental protection, but also with the development of the economy , over-exploitation, and excessive use of pesticides and fertilizers have led to more and more serious pollution of the planting soil, soil alkalization, serious soil erosion, and heavy metals exceeding the standard, so that even if jasmine flowers are planted without pesticides and fertilizers in the later stage, the quality of jasmine flowers will not reach the level of environmental protection. public nuisance
