Problems solved by technology

At present, there are only domestic reports on the effects of selenium-enriched organic fertilizers, trace element fertilizers in amino acids, trace element fertilizers in humic acids, and mineral fertilizers on the selenium-enriching ability of broad beans. All patents, achievements and literature related to the production of selenium-enriched agricultural products have added exogenous selenium, mainly sodium selenate, sodium selenite, selenium dioxide and their derivatives, which are toxic substances and have high agricultural production costs. And it is easy to cause environmental pollution; the applicant applied for a foliar fertilizer for improving the selenium-enriching ability of potatoes in 2011, and the application number is 201110020584.5, which discloses the foliar fertilizer for the selenium-enriching ability of potatoes

example 1

[0004] Example 1: Cultivate horse teeth broad beans in selenium-enriched soil using conventional cultivation techniques. Spray a foliar fertilizer that improves the selenium-enriching ability of broad beans before 9:00 a.m. in the blooming period of broad beans. 0.01g, 0.01g leucine, 0.01g histidine, 1g methionine, 0.01g cystine, 15g threonine, 15g phenylalanine, 40g serine, 40g tryptophan, VC: 40 mg, VE: 40 mg, VB1: 50 mg, VB6: 40 mg, VB12: 40 mg, 116.5 grams of 99% potassium sulfate, including 60 grams of potassium oxide and 2 grams of coenzyme II, mixed well and then sprayed. Mu sprayed 15 kilograms of clear water, and the results are shown in Table 1.

example 2

[0005] Example 2: Cultivate Qinghai No. 9 broad bean with conventional cultivation techniques in dry land with selenium-enriched soil. Spray a foliar fertilizer to improve the selenium-rich capacity of broad bean before 9:00 a.m. at the flowering stage of broad bean. The amount of water per mu is 15 kg, glutamine 10 grams of acid, 10 grams of leucine, 10 grams of histidine, 50 grams of methionine, 40 grams of cystine, 0.01 grams of threonine, 0.01 grams of phenylalanine, 0.01 grams of serine, 1 gram of tryptophan, VC: 0.01 mg, VE: 0.01 mg, VB1: 0.01 mg, VB6: 0.01 mg, VB12: 0.01 mg, 2.1 g of 95% potassium sulfate, which contains 1 g of potassium oxide, 0.01 g of coenzyme II, stir well and then spray , the control group was sprayed with 15 kilograms of clear water per mu, and the results are shown in Table 1.

example 3

[0006] Example 3: Cultivate Qinghai No. 12 broad bean by conventional cultivation techniques in dry land with selenium-enriched soil. Spray a foliar fertilizer that improves the selenium-enriching capacity of broad bean before 9:00 a.m. at the flowering stage of broad bean. 5 grams of acid, 10 grams of leucine, 5 grams of histidine, 20 grams of methionine, 30 grams of cystine, 15 grams of threonine, 15 grams of phenylalanine, 20 grams of serine, 35 grams of tryptophan, VC : 30 mg, VE: 20 mg, VB1: 20 mg, VB6: 20 mg, VB12: 10 mg, 96 grams of 95% potassium sulfate, including 47 grams of potassium oxide and 1 gram of coenzyme Ⅱ, sprayed after stirring evenly, the control group Spray 15 kilograms of clear water per mu, and the results are shown in Table 1.

Abstract

The invention relates to leaf fertilizer for improving the capability of selenium enrichment of fava beans, and belongs to the technical field of agricultural leaf fertilizer. The leaf fertilizer adopts the formula that water of 15 kg, glutamic acid of 0.01-10 g, leucine of 0.01-10 g, histidine of 0.01-10 g, methionine of 1-50 g, cystine of 0.01-40 g, threonine of 0.01-15 g, phenylalanine of 0.01-0.15 g, serine of 0.01-40 g, tryptophan of 1-40 g, VC of 0.01-40 mg, VE of 0.01-40 mg, VB1 of 0.01-50 mg, VB6 of 0.01-40 mg, VB12 of 0.01-40 mg, potassium oxide of 1-60 g and coenzyme II of 0.01-2 g are uniformly stirred. The invention has the advantages that exogenous selenium is not needed, the formula is simple, the preparation is easy, the leaf fertilizer facilitates enhancing the capability of selenium enrichment of fava beans, and enables the selenium content of fava beans to reach the selenium enrichment standard of 0.01 mg / kg, and the use cost is 30-70 yuan / mu; besides, the antiviral performance and stress resistance of fava beans can be improved, the agricultural production cost and environmental pollution can be reduced, and excellent economic and ecological benefits are obtained.

Description

1. Technical field [0001] The invention relates to a foliar fertilizer for improving the selenium-enriching ability of broad beans, and belongs to the technical field of agricultural foliar fertilizers. 2. Background technology [0002] Selenium is one of the essential trace elements for the human body. Selenium-rich foods have obvious anti-aging, anti-cancer, anti-radiation damage, anti-mutation, anti-oxidation, hinder the formation of nitrous acid, and have good effects on reproductive system diseases. Beneficial to people's health. At present, there are only domestic reports on the effects of selenium-enriched organic fertilizers, trace element fertilizers in amino acids, trace element fertilizers in humic acids, and mineral fertilizers on the selenium-enriching ability of broad beans. All patents, achievements and literature related to the production of selenium-enriched agricultural products have added exogenous selenium, mainly sodium selenate, sodium selenite, seleni...
