Problems solved by technology

However, sodium selenate is a highly toxic chemical, which can easily cause great harm to the health of operators during production
At the same time, the residual sodium selenate that has not been absorbed by plants will pose a great threat to the health of consumers
[0007] On the other hand, in the existing selenium-enriched fertilizers, except for the high content of selenium, the content of other nutrient elements is relatively small, and even completely does not contain some trace elements necessary for plant growth.
The single use of this kind of selenium-rich fertilizer will have a great impact on the yield and quality of dishes
And if other fertilizers are applied in addition, it will not only increase the purchase cost, but also increase the labor cost
[0008] Third, many traditional selenium-rich fertilizers need to be applied directly to the soil
On the one hand, the selenium element in the fertilizer will be leached into the deep soil with irrigation, which is not conducive to the utilization of vegetables and will cause waste of fertilizer
On the other hand, heavy metal elements in fertilizers will continue to accumulate in the cultivated soil as they are applied, and then eventually enter the plants, causing potential harm to the safety of dishes

Embodiment Construction

[0014] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] The present invention will be further described below in conjunction with specific embodiment

[0016] (1) the formula of the selenium-enriched fertilizer of the embodiment of the present invention and application method are as follows:

[0017] The fertilizer formula is as follows:

[0018]

[0019] In the selenium-enriched fertilizer of the present invention, sodium selenite is used instead of sodium selenate, which avoids the health threat of the fertilizer itself to producers and consumers. In addition, in addition t...

Abstract

The invention discloses a selenium-rich fertilizer for fruits/vegetables. Every kilogram of fertilizer contains 165.43g of urea, 178.87g of potassium chloride, 363.02g of calcium superphosphate, 123.25g of magnesium sulfate, 3.25g of ferrous sulfate, 0.53g of manganese sulfate, 0.06g of zinc sulfate, 0.02g of copper sulfate, 0.72g of boric acid, 10.00g of sodium selenite and 154.85g of ground phosphorite. The selenium-rich fertilizer for fruits/vegetables has important functions for producing selenium-rich fruits/vegetables, is convenient to apply, has the advantages of high safety and lower cost, is beneficial to popularization, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of fruit and vegetable fertilizers, in particular to a fruit and vegetable selenium-rich fertilizer used for cultivating selenium-rich fruit and vegetables on selenium-deficient soil. Background technique [0002] Selenium (Se) is a trace element with a molecular weight of 78.96. It is located in the VIA group of the chemical element periodic table, and its chemical properties are similar to the sulfur element of the same group. The current general view is that an appropriate amount of selenium in the diet plays an important role in maintaining the health of the human body. First of all, selenium plays an irreplaceable role in improving the body's antioxidant capacity. In addition, selenium also has important physiological functions such as anti-cancer, liver protection, binding heavy metals, and prevention and treatment of cardiovascular diseases. At the same time, selenium deficiency is also an important cause of ...
