Embodiment 1

[0030] Cassava was treated with 3 different selenium fertilizers.

[0031] Treatment 1 uses organic selenium liquid fertilizer with a selenium content of 25.00 mg / l, treatment 2 uses inorganic selenium soil with a selenium content of 500.00 mg / kg for fertilization, and treatment 3 uses edible cassava selenium-enriched foliar fertilizer of the present invention. details as follows:

[0032] Treatment 1 was sprayed with organic selenium liquid fertilizer with a selenium content of 25.00 mg / l, and sprayed with 500 times of liquid;

[0033] The inorganic selenium soil of treatment 2 is sodium selenite 1.5g, potassium sulfate fertilizer (K 2 O content 51%) 350g, calcium magnesium phosphate fertilizer (P) 110g, organic fertilizer 480g; 750 kg / hm 2 Acupoints;

[0034] Treatment 3 adopts selenium-enriched foliage fertilizer of the present invention, with sodium selenite 5.5 g, potassium dihydrogen phosphate 160 g, boron fertilizer 1.0 g, nitrogen fertilizer 3.5 g, organic matter 2....

Embodiment 2

[0039] On the basis of Example 1, another two selenium-enriched fertilizers of the present invention with different proportions were prepared for comparison with Treatment 3.

[0040] Treatment 4 used 6.0 g of sodium selenite, 160.0 g of potassium dihydrogen phosphate, 1.0 g of boron fertilizer, 3.5 g of nitrogen fertilizer, 2.5 g of organic matter, 12.8 g of compound amino acids, 27 g of disodium edetate, and 1 g of soil temperature -80 to 600 ml is the mother liquor. 100 times liquid spraying (45.66 mg / l).

[0041] Treatment 5 was treated with 6.6 g of sodium selenite, 160.0 g of potassium dihydrogen phosphate, 1.0 g of boron fertilizer, 3.5 g of nitrogen fertilizer, 2.5 g of organic matter, 12.8 g of compound amino acids, 27 g of disodium edetate, and 1 g of soil temperature -80 to 600 ml is the mother liquor. 100 times liquid spraying (50.23 mg / l).

[0042] The following is the effect comparison of treatment 3, treatment 4 and treatment 5 after implementation:

Abstract

The invention belongs to the field of agricultural fertilizers, and particularly provides a selenium-rich foliage fertilizer for edible cassava. The selenium-rich foliage fertilizer for the edible cassava comprises a nutrient solution, a chelating agent and a surfactant, wherein the nutrient solution is prepared from 160 parts of monopotassium phosphate, 5.5 to 6.5 parts of sodium selenite, 1.0 part of a boron fertilizer, 3.5 parts of a water-soluble nitrogen fertilizer and 2.5 parts of organic matters; the chelating agent is prepared from 12.8 parts of compound amino acid and 27 parts of ethylenediamine tetraacetic acid disodium salt. The selenium-rich foliage fertilizer for the edible cassava is efficient and environmentally friendly, and is easy to prepare.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and specifically provides an edible cassava selenium-enriched foliage fertilizer for the production of selenium-enriched food and a preparation method thereof. Background technique [0002] Selenium-enriched fertilizers are divided into base selenium-enriched fertilizers and foliar selenium-enriched fertilizers according to the application method. At present, many selenium-rich fertilizers on the market are mostly used for tea trees, rice, fruit trees, etc., and the effect of selenium fertilizers on many markets is not particularly ideal. Inventors Qin Keming (application number 201710035059.8), Li Qi, etc. (application number 201610618397.x) invented "a selenium-enriched sweet potato fertilizer and its preparation method" and "a selenium-enriched foliar fertilizer" respectively. Fertilizer, yet the selenium-enriched fertilizer invented by it is complicated to make and inconveni...
