Description
Technical Field
The invention relates to a dandelion seed soaking liquid meeting the microelement water-soluble fertilizer standard and an application method thereof.
Background
The dandelion belongs to perennial herb of Compositae, is named as Huanghualang, herba Veronicae Divaricatae, milk juice grass and the like, is bitter, sweet and cold in taste, enters liver and stomach channels, and has the effects of resisting oxidation, resisting tumors, enhancing immunity, inhibiting bacteria and the like. The dandelion has good taste and rich nutrition, is a health-care vegetable, and is one of hundreds of plants which are homologous in medicine and food and are listed by the national committee. With the gradual understanding of people on the health care efficacy of the dandelion, the utilization of the dandelion begins to develop into diversification of Chinese patent medicines, beverages, tea leaves and the like, the demand is increased year by year, while the wild resources of the dandelion are reduced year by year, so that the artificial planting of the dandelion has higher economic benefit and good development prospect. However, from the start of sowing to the end of emergence, the seeds remain in the soil environment for a considerable period of time, which is variable or even unfavorable, and measures are therefore required to increase the rate of emergence of the sprouts. Proper seed treatment before sowing is beneficial to complete seedlings, uniform seedlings, even seedlings and strong seedlings, and is one of effective measures for improving the yield.
In recent years, researchers have paid attention to the content of trace elements in the dandelion, and researches have shown that the dandelion contains a large amount of potassium, the essential trace nutrient elements are mainly zinc, manganese, copper and iron, the average content ratio of zinc (Zn) to copper (Cu) is about 3, the application of a proper amount of nitrogen fertilizer can provide high yield and quality of the dandelion, and the optimal nitrogen (N) application amount is 73.6-110.4kg/hm2. Cultivated lands lack trace elements of iron, copper, manganese and zinc in China account for 5%, 6.9%, 34.5% and 51.5% respectively, but iron-deficient soil in traditional Chinese medicine cultivation bases is relatively less. Therefore, Zn (NO) is mainly developed aiming at the nutrition characteristics of dandelion3)2、Cu(NO3)2KNO in constant concentration system3-Mn(NO3)2-H2And (3) performing O-phase balance research, and preparing dandelion soaking liquid meeting the microelement water-soluble fertilizer standard (NY1428-2010) according to a phase diagram.
