Abstract
The invention provides a selenium-enriched plant nutritional agent. The selenium-enriched plant nutritional agent comprises the following components by weight ratio: 20%-25% of dried cow dung, 20%-25% of dried straw powder, 25%-30% of attapulgite, 5%-7% of a selenium source, 2%-3% of potassium phosphate, 2%-3% of calcium superphosphate, 2%-3% of plant ash and 15%-20% of river sediment powder. The selenium-enriched plant nutritional agent has the following benefits that a slow-release effect is great, and the nutritional agent is convenient to store for a long term with a good effect.
Description
Technical field
The invention belongs to Selenium-rich nutrient field, be specifically related to a kind of enriched-selenium plant nutrient.
Background technology
Plant nutrient agent is for a kind of fertilizer additive in growing process, can improve the fertility in some soils, some be lacked to the soil of some element-specific, can by trophic structure adjustment period of interpolation specific plant nutrient agent.
Selenium is the trace element of needed by human, participates in multiple selenoenzyme and Selenonic protein in synthesized human, can improve human immunity, promote the synthesis of lymphocytic propagation and antibody and immunoglobulin (Ig).Simultaneously; selenium is also known as " anticancer king " in body trace element; existing scientific research shows; the height of blood selenium level is closely related with the generation of cancer; a large amount of survey data also illustrates; a regional food and the height of Selenium in Soils content have direct relation with the sickness rate of cancer, and therefore, people can select some rich selenium foods usually.
Therefore, for some scarce selenium areas, select suitable enriched-selenium plant nutrient to improve the selenium content in plant, and then promote that the selenium intake of local people is a kind of methods of recommendation.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of enriched-selenium plant nutrient, the soil nutrient structure lacking selenium area can be improved, and there is good slow release effect.
The present invention is achieved through the following technical solutions.
A kind of enriched-selenium plant nutrient, comprises the component of following weight proportion: dry cow dung 20% ~ 25%; Dry straw powder 20% ~ 25%; Attapulgite 25% ~ 30%; Selenium source 5% ~ 7%; Potassiumphosphate 2% ~ 3%; Calcium superphosphate 2% ~ 3%; Plant ash 2% ~ 3%; Bed mud powder 15% ~ 20%.
The present invention is by selecting suitable component and proportioning, wherein dry cow dung and dry straw powder provide very sufficient carbon source to plant, take off energy release of carbon dioxide, be supplied to plant in dividing of microorganism, discharge the trace element that plant-growth is necessary simultaneously, ensure plant normal growth; Attapulgite is a kind of mineral clay with vesicular structure, has certain adsorption, and selenium source is adsorbed in the gap of its porous by attapulgite, can in soil slow releasing, selenium source is existed at soil stabilization, is not run off, improve remaining time, reduce the pollution to environment; The interpolation of potassiumphosphate and calcium superphosphate, can provide the bioelement needed for plant further, and play the effect regulating soil acidity or alkalinity, in weakly alkaline environment, the selenium of solubilised state can fully be absorbed by plant the most fully simultaneously; Plant ash can play certain hygroscopic desiccation effect, is convenient to the permanent preservation of this enriched-selenium plant nutrient; Containing a large amount of high-quality soil ulmin and the trace element needed for plant in bed mud, being dried after making powder to be dispersed in plant nutrient agent uniformly, and the effective constituent in bed mud powder also can produce adsorption effect with attapulgite, plays the object of slowly-releasing, extend fertilizer efficiency.
As preferentially, described selenium source is selenium ore nanometer powder, the selenium content >=20g/kg in described selenium ore nanometer powder.Selenium ore selected by selenium source in the present invention is preferably the high selenium ore of enshi, and in this ore, selenium content reaches more than 20g/kg, and the content of other heavy metals must not exceed the index in the relevant fertilizer standard of country.By this ore after multi-stage crushing through nanometer pulverize, the effect that selenium source is adsorbed by attapulgite can be improved, also improve the efficiency that selenium element is absorbed by plants.
As preferably, described selenium ore nanometer powder is the selenium ore nanometer powder through activation treatment, and activation temperature is 220 DEG C ~ 250 DEG C.Ore is through the process of activating technology, and the selenium that the activity selenium of the inside of ore being changed into fully can be beneficial to by plant is higher, improves raw material availability.
As preferably, described bed mud powder is the fresh bed mud bed mud powder through drying, pulverizing, after activation treatment, and this activation temperature is 110 DEG C ~ 130 DEG C.Organic matter in bed mud powder after activation and ratio >=1/7 of inanimate matter, the activation of bed mud powder is selected to carry out at a lower temperature, is conducive to the maintenance of its inner soil ulmin structure and energy while drying.
Compared with prior art, the present invention has following beneficial effect: provide a kind of enriched-selenium plant nutrient, and this nutrition agent has good slow release effect, and convenient long-term preservation, effective simultaneously.
