Description
Technical field
The present invention relates to the eggplant culture technique, be specially a kind of method that makes eggplant be rich in the various trace elements such as germanium selenium zinc chrome vanadium.
Background technology
Eggplant is an important kind of solanaceous vegetables, is one of vegetables summer and autumn.In order further to improve the value medical health care of eggplant, obtaining certain achievement aspect increase eggplant healthy trace elements with household kind and the content thereof.Chinese patent Granted publication CN 100562247C patent discloses a kind of " breeding method that contains the iodine eggplant ", before the eggplant seedling field planting, use sufficient base manure, and with the disposable top layer that is manured into soil of solid iodine fertilizer, or before eggplant is gathered, spray liquid iodine fertilizer for 5-6 time by stages, can make the eggplant amount of iodine after the maturation reach 0.14-1.90mg/kg; Chinese patent application numbers 201010580190.0 discloses a kind of " selenium-enriched eggplants and production method thereof ", in the eggplant seedling raising stage, in seedling medium or the field furrow of growing seedlings, apply the selenium-rich nutritive agent that is formed by nanometer selenium plant nutrient agent, microorganism fertilizer and boiler ash sediment, balled transplanting, eggplant shoot root section is contained seleno matter bring the land for growing field crops into, final results selenium-enriched eggplants, its Se content 10-300ug/kg.Although these methods can both realize inventor's technical purpose, but, the trace element of its increase is relatively single, and the value medical health care of the eggplant that obtains is had a greatly reduced quality, and it is not yet seen the report that can make eggplant be rich in simultaneously the special beneficial elements such as germanium, selenium, zinc, chromium, vanadium.And in " selenium-enriched eggplants and production method thereof ", when eggplant seedling raising, just the selenium-rich nutritive agent is joined seedling medium or the field furrow of growing seedlings in, what the addition of selemium nutrition agent not only can affect eggplant seedling breeds that (the selenium addition is little, then the Se content of fruit is not obvious, the selenium addition is large, then can hinder seedling, and this also the method gained fruit Se content reason on the low side just), and owing to when growing seedlings, needing thinning, objectively also caused the waste of selemium nutrition agent.
Existing studies show that, in natural situation, the trace element that people obtain comes from vegetable food more than 70%, and more be conducive to the absorption of human body utilization by the mode that obtains organic trace element from vegetable food, more be conducive to safeguard the Equilibrium of Trace Elements of human body, and the trace element in the plant food directly or indirectly derives from soil.But because the difference of the many factors such as the condition that soil forms, environment, kind and the quantity variance of contained trace element are huge.For example, the selenium constituent content distributed pole at the earth's surface;on the face of the globe in the soil is inhomogeneous, and it is serious that some areas lack selenium, and according to the previous findings of the survey of the units such as the Chinese Academy of Sciences, the area of China more than 70% lacks selenium, the serious selenium that lacks in the area more than 30%.Therefore, the vegetable food that trace element is rich in exploitation satisfies that the needs tool to trace element is of great significance in the human normal physiology course.
Applicant's formerly patent application " a kind of preparation method and using method of rich germanium zinc selenide thing ion nutritional liquid fertilizer " (application number 201210053105.4) discloses a kind of rich germanium zinc selenide thing ion nutritional liquid fertilizer.In its concrete application, in the cultivation of the edible mushrooms such as woodear, glossy ganoderma and mushroom, succeed, use this fertilizer make respectively woodear, glossy ganoderma and conidial powder thereof and mushroom be rich in simultaneously the trace elements such as germanium, selenium, zinc, chromium, vanadium (see applicant's previous application " a kind of make woodear be rich in the trace element method ", application number 201210131257.1; A kind of method that makes mushroom be rich in trace element, application number 201210314959.3; A kind of method that makes glossy ganoderma and conidial powder thereof be rich in trace element, application number 201210314960.6), but not yet in the plantation of fruits and vegetables class, obtain to use.
