Problems solved by technology

[0004] After years of research and experiments, it was found that although spraying fertilizers on selenium-enriched leaves in the past can increase the selenium content of wheat seeds to a certain extent, it is still difficult to meet the production requirements of selenium-enriched agricultural products. The waxy layer of the plant affects the entry of selenium and other nutrients into the plant, especially in arid and semi-arid regions

Embodiment 1

[0022] The experiment was completed at the Shenyang Institute of Applied Ecology, Chinese Academy of Sciences. The soil for testing was collected from the Shenyang Ecological Experiment Station, which is located in the center of the Liaohe Plain, about 35km away from Shenyang City. The soil is meadow brown soil. This plot has not used chemicals for more than 10 years and is a clean soil. The basic physical and chemical properties of the soil 0-20cm for the test are as follows: the available nitrogen, phosphorus, and potassium of the soil are 80.4, 12.0, and 77.0 mg / kg respectively. The selenium content of the soil is 0.14 mg / kg. Other physical and chemical properties are listed in Table 1.

[0023] Table 1

[0024]

[0025] Test variety: the wheat variety is Liaochun No. 10.

[0026] The ceramic pots used in the experiment are 20cm high and 15cm in diameter. Each pot is filled with 2.5kg of soil. After the soil is sieved through a 2mm sieve, the base fertilizer is added. ...

Embodiment 2

[0035] Experimental site, experimental method and test soil are the same as in Example 1.

[0036] In the selenium-rich fertilizer in parts by weight, selenium element: iron element: manganese element: copper element: zinc element magnesium element: alkyl polyglycoside: chitosan: sulfur: chitosan quaternary ammonium salt=1:3.0:0.6 :0.6:0.6:0.8:2.5:8.0:3.6:0.8.

[0037] The selenium element is selected from sodium selenite; the iron element is selected from ferrous sulfate; the manganese element is selected from manganese sulfate; the copper element is selected from copper sulfate; the zinc element is selected from zinc sulfate; and the magnesium element is selected from magnesium sulfate.

[0038] Application preparation method:

[0039] Mix selenium, iron, manganese, copper, zinc, magnesium, and chitosan raw materials according to the above ratio of parts by weight, dilute to 1L with water, use it as preparation A, and put it into an opaque plastic bottle; then put the alkyl...

Embodiment 3

[0043] In 2012, the selenium-enriched fertilizer of the present invention was used in a pilot-scale application in a wheat production base. The implementation site is Nanchang Village, Dashetai Town, Bayannaoer City, Inner Mongolia, with an implementation area of ​​10 mu. Among them, the area of ​​sandy loam and heavy loam is 5 mu each. According to the national soil type distribution and soil physical and chemical properties, it is confirmed that the soil type is irrigated meadow chestnut soil. Its main physical and chemical properties are listed in Table 2.

Abstract

The invention relates to an agricultural product production technique in the field of agricultural fertilizers, particularly a high-efficiency selenium-rich wheat or rice foliage spray fertilizer. The foliage spray fertilizer is composed of the following elements in parts by weight: 1 part of selenium, 2.0-3.0 parts of iron, 0.4-0.6 part of manganese, 0.4-0.6 part of copper, 0.4-0.6 part of zinc, 0.7-0.8 part of magnesium, 1.5-2.5 parts of alkyl polyglucoside, 7.0-8.0 parts of chitosan, 2.6-3.6 parts of sulfur and 0.7-0.8 part of chitosan quaternary ammonium salt. After being sprayed to the wheat or rice foliage, the spray fertilizer can be quickly absorbed by the plant, and can supplement selenium and multiple necessary nutrient elements for plants. The foliage spray fertilizer has the obvious effects of promoting plant growth, reducing the plant diseases, increasing the yield, enriching selenium in the product and the like.

Description

technical field [0001] The invention relates to the production technology of agricultural products in the field of agricultural fertilizers, in particular to a high-efficiency selenium-enriched wheat or rice foliar spray fertilizer. Background technique [0002] Selenium is an essential trace element for the healthy growth of humans and animals. Selenium is called "the fire of life" by the medical and nutritional circles at home and abroad. Agent" and other reputation. Selenium deficiency will directly lead to the decline of human immunity and threaten human health. More than 40 kinds of diseases in the human body are related to selenium deficiency. Proper selenium supplementation has a positive effect on improving human immunity, anti-oxidation, delaying aging, protecting and repairing damaged cells, preventing and fighting cancer, preventing and treating cardiovascular and cerebrovascular diseases, and reducing the toxicity of environmental pollutants. Food is the main c...
