Embodiment 1

[0018] A method for cultivating selenium-enriched, zinc-enriched, and calcium-enriched corn, comprising the following main steps:

[0019] 1. When planting, soak the corn seeds for 3 hours with selenium Fengbao dilution solution with a concentration of 15000 times;

[0020] 2. When plowing and plowing the land, apply quicklime at an amount of 100kg per mu;

[0021] 3. When planting, apply basal fertilizer in planting holes, and mix agricultural selenium fertilizer and zinc sulfate into the basal fertilizer. The ratio of materials used is: base fertilizer: agricultural selenium fertilizer: zinc sulfate=1000︰1︰5;

[0022] 4. Apply topdressing fertilizer: use 20g of agricultural selenium fertilizer per mu, mix water and drench the roots; use it 2-3 times during the growth period;

[0023] 5. Apply foliar fertilizer, use 12000 times selenium Fengbao dilution, 0.3% zinc sulfate dilution and 0.9% calcium nitrate, respectively in the seedling stage, vigorous growth stage and floweri...

Embodiment 2

[0026] A method for cultivating selenium-enriched, zinc-enriched, and calcium-enriched corn, comprising the following main steps:

[0027] 1. When planting, soak the corn seeds for 3 hours with a sodium selenite dilution solution with a concentration of 15000 times;

[0028] 2. When plowing and plowing the land, apply quicklime at an amount of 100kg per mu;

[0029] 3. When planting, apply basal fertilizer in planting holes, and mix agricultural selenium fertilizer and zinc sulfate into the basal fertilizer. The ratio of materials used is: base fertilizer: agricultural selenium fertilizer: zinc sulfate=1000︰1︰5;

[0030] 4. Apply topdressing fertilizer: use 20g of agricultural selenium fertilizer per mu, mix water and drench the roots; use it 2-3 times during the growth period;

[0031] 5. Apply foliar fertilizer, use 12000 times sodium selenite dilution, 0.4% zinc sulfate dilution and 0.8% calcium nitrate, respectively in the seedling stage, vigorous growth stage and floweri...

Embodiment 3

[0033] A method for cultivating selenium-enriched, zinc-enriched, and calcium-enriched corn, comprising the following main steps:

[0034] 1. When planting, soak the corn seeds for 3 hours with a selenium-rich amino acid dilution solution with a concentration of 15000 times;

[0035] 2. When plowing and plowing the land, apply quicklime at an amount of 100kg per mu;

[0036] 3. When planting, apply basal fertilizer in planting holes, and mix agricultural selenium fertilizer and zinc sulfate into the basal fertilizer. The ratio of materials used is: base fertilizer: agricultural selenium fertilizer: zinc sulfate=1000︰1︰5;

[0037] 4. Apply topdressing fertilizer: use 20g of agricultural selenium fertilizer per mu, mix water and drench the roots; use it 2-3 times during the growth period;

[0038] 5. Apply foliar fertilizer, use 12000 times of selenium-rich amino acid dilution, 0.5% zinc sulfate dilution and 0.6% calcium nitrate, respectively in the seedling stage, vigorous gro...

Abstract

The invention discloses a selenium, zinc and calcium rich corn cultivation method including the steps of (1), soaking corn seeds by selenium fertilizer diluent for two to four hours, taking the seeds out of the selenium fertilizer diluent and planting the seeds after drying the same, and applying 25-150kg of quick lime per mu according to the state of pH value of soil; (2), mixing selenium fertilizer and zinc fertilizer into base fertilizer during fertilizer applying; (3), mixing 10-50 g of selenium fertilizer per mu with water to water the roots and then applying topdressing; (4), spraying selenium fertilizer diluent, zinc fertilizer diluent and calcium fertilizer diluent to leaf surfaces of corn during the growth period by two to six times. By the selenium, zinc and calcium rich corn cultivation method, selenium, zinc and calcium contents of corn are increased further, nutritive value and health value of corn are enriched, and physical health of people eating the corn can be improved.

Description

technical field [0001] The invention relates to corn cultivation, in particular to a cultivation method for selenium-enriched, zinc-enriched and calcium-enriched corn in the southern acidic red soil area. Background technique [0002] Corn contains a large amount of nutritional and health-care substances. The glutathione it contains is an anti-cancer factor. The riboflavin, vitamins and other nutrients contained in corn have a great effect on preventing diseases such as heart disease and cancer. It can accelerate the elimination of toxins in the body, and natural vitamin E has the functions of promoting cell division, delaying aging, lowering serum cholesterol, and preventing skin lesions. According to the Internet search, the current research on corn cultivation technology mainly focuses on high-yield cultivation, and there are few reports on the research on further improving other nutritional and health components in corn. Contents of the invention [0003] The purpose ...
