Planting method of organic selenium-enriched flos chrysanthemi

Abstract

The invention discloses a planting method of organic selenium-enriched flos chrysanthemi. The planting method comprises the following steps of firstly preparing selenium-enriched foliage fertilizers for flos chrysanthemi: uniformly mixing EM original liquid namely a functional live bacterium agent, a selenium-enriched agent, a high-efficient organic silicon agricultural spraying addition agent and water in the mass ratio of the EM original liquid namely functional live bacterium agent, to the selenium-enriched agent, to the high-efficient organic silicon agricultural spraying addition agent and to the water being (4-6) to (10-15) to (0.1-0.2) to (300-450) so as to obtain selenium-enriched foliage fertilizers for the flos chrysanthemi; and then applying the foliage fertilizers: adding water for diluting the selenium-enriched foliage fertilizers for the flos chrysanthemi until the volume of the diluted selenium-enriched foliage fertilizers is 100-150 times of that of the selenium-enriched foliage fertilizers, at 4 p.m. of a cloudy day or a fine day 7-10 days before harvesting chrysanthemum flowers, performing uniformly spraying once on spraying points of rear leaf surfaces, spraying upper and lower leaves so that the leaves are uniformly covered with medicinal liquid until the leaves are fully wet and the medicinal liquid does not drop, and preventing the situation that the sprayed leaves are in contact with rain within 24 hours after the leaves are sprayed. The planting method disclosed by the invention is simple, outstanding in selenium-enriched effects and suitable for large-scale production, and the flos chrysanthemi produced by the method has the advantages of containing selenium, being high in content of organic selenium, good in quality and high in eating safety.

Description

technical field [0001] The invention relates to the field of chrysanthemum planting, in particular to a method for planting organic selenium-enriched chrysanthemum. Background technique [0002] Chuzhou chrysanthemum is one of the four major local medicinal materials in Anhui Province. It ranks first among the four major medicinal chrysanthemums in the country for its unique medicinal and health care values. It was accepted as a tribute in the Qing Dynasty, so it is also called "Chuzhou Gongju". At present, other chrysanthemums are developing selenium-enriched chrysanthemums, but the research and development of Chuju, which has unique medicinal and health value and ranks first among the four major medicinal chrysanthemums in the country, is still blank. [0003] Organic selenium-enriched chrysanthemum is to use selenium-enriched technology to make chrysanthemum contain selenium and organic selenium during the production process of chrysanthemum. The reasons for researching ...

Problems solved by technology

[0008] (2) Although some methods obtain higher total selenium content of chrysanthemum, the method is tedious, time-consuming and labor-intensive, and the fermentation broth needs to be prepared first, so it is difficult to adapt to large-scale production

[0009] (3) Another method is to use the red heart white chrysanthemum of Hangbai chrysanthemum strain as the chrysanthemum for testing. Although a very high chrysanthemum total selenium content has been obtained, the highest chrysanthemum total selenium content reaches 11.03mg / kg (organic selenium content is not reported). , but the operation method is more complicated, and the large-scale production is more difficult. This method is the sand culture pot method

The test substrates were river sand and vermiculite. The river sand was first rinsed with tap water and then dried. The vermiculite was first soaked in dilute hydrochloric acid solution for 48 hours, washed repeatedly with tap water and then dried. Then, 9.7kg of river sand and 0.3 kg mixed and put into a plastic basin, there are small holes in the bottom of the basin, equipped with a basin support, and nylon yarn is laid on the bottom of the basin before filling the basin, which is one of the reasons why it is difficult to scale production
