Selenium-rich strawberry nutritional agent

Abstract

The invention discloses a selenium-rich strawberry nutritional agent. The nutritional agent is prepared from, by weight, 1-2 parts of selenic amino acid rare earth, 1-3 parts of sodium selenite, 1-5 parts of trace elements, 0.1-0.6 part of an alkyl sulfonate surfactant, 1-5 parts of 6-benzylaminopurine, 5-10 parts of Disodium ethylenediamine tetraacetate and 1-3 parts of attapulgite. The selenium-rich strawberry nutritional agent has advantages that nutrient structure and quality of selenium-rich strawberry planting land are improved, selenium-rich strawberries are guaranteed of sufficient nutrient absorption, and strawberry yield is increased. In practical fertilizer production, a method is simple, attapulgite plays a role in adhesion in fertilizer production and also has a certain slow release function to enable slow release of fertilizer efficiency in a whole utilization period, and accordingly problems of low selenium utilization rate, conversion rate and the like caused by spraying of selenium fertilizers are avoided, and high organic selenium content is achieved by root application of special selenium fertilizers for the strawberries.

Description

technical field [0001] The invention relates to the field of strawberry planting, in particular to a selenium-enriched strawberry nutrient. Background technique [0002] Selenium is a beneficial element required by higher plants. Supplementing an appropriate amount of selenium can enhance the stress resistance of plants, increase the accumulation of organic matter, and achieve the purpose of increasing production. At present, the main form is to apply selenium fertilizer to the soil, but the biologically available selenium in the soil is susceptible to changes due to the influence of soil pH, and under acidic and reducing conditions, selenate is prone to reduction reactions and becomes unavailable. Elemental selenium is absorbed and utilized by plants. Strawberry is a kind of red flower and fruit. Strawberry has high nutritional value and is rich in vitamin C, which can help digestion. At the same time, strawberry can also strengthen the gums, freshen the breath, and moistu...

In addition, strawberries are best eaten after meals, because they contain a lot of pectin and cellulose, which can promote gastrointestinal motility, help digestion, improve constipation, prevent hemorrhoids, and intestinal cancer. Selenium-enriched strawberries are an extension of strawberries during planting. A new type of health-care strawberry not only has the original taste of strawberries, but also is rich in trace elements, which is beneficial to human health. In the actual planting of selenium-rich strawberries, the demand for fertilizers is relatively harsh. If the selection of fertilizers does not meet the specifications, it will directly affect When it comes to the nutrients of selenium-enriched strawberries and the yield of selenium-enriched strawberries, the fertilizers on the market have no obvious effect on selenium-enriched strawberries.
