Embodiment 1

[0018] A cultivation method for selenium-enriched, zinc-enriched, and calcium-enriched Chinese yam comprises the following main steps:

[0019] 1. When planting, soak the stems of Chinese yam for 3 hours with selenium Fengbao diluent 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, 0.4% zinc sulfate dilution and 0.8% calcium nitrate, respectively in the seedling stage, vigorous growth stage, and p...

Embodiment 2

[0026] A cultivation method for selenium-enriched, zinc-enriched, and calcium-enriched Chinese yam comprises the following main steps:

[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, 0.5% zinc sulfate dilution and 0.6% calcium nitrate, respectively in the seedling stage, vigorous growth stage, and ...

Embodiment 3

[0033] A cultivation method for selenium-enriched, zinc-enriched, and calcium-enriched Chinese yam comprises the following main steps:

[0034] 1. When planting, soak the Chinese yam stems 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 12,000 times selenium-rich amino acid dilution, 0.3% zinc sulfate dilution and 0.8% calcium carbonate, respectively in the seedling stage, ...

Abstract

The invention discloses a selenium, zinc and calcium rich Chinese yam cultivation method including the steps of (1), soaking seedlings or roots of Chinese yam by selenium fertilizer diluent for two to four hours, planting or culturing seedlings after taking the seedlings or roots out of the selenium fertilizer diluent to dry 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 Chinese yam during the growth period by two to six times. By the selenium, zinc and calcium rich Chinese yam cultivation method, selenium, zinc and calcium contents of Chinese yam are increased further, nutritive value and health value of Chinese yam are enriched, and physical health of people eating the Chinese yam can be improved.

Description

technical field [0001] The invention relates to yam cultivation, in particular to a cultivation method of yam rich in selenium, zinc and calcium in acidic red soil areas in southern China. Background technique [0002] Huaishan, also known as yam, contains amylase, polyphenol oxidase and other substances, which are beneficial to the digestion and absorption of the spleen and stomach. And it contains a variety of nutrients, which can strengthen the body, nourish the kidney and nourish the essence. According to the search on the Internet, the current research on the cultivation technology of yam mainly focuses on high-yield cultivation, and there are few reports on the research on further improving other nutritional and health components in yam. Contents of the invention [0003] The purpose of the present invention is to provide a cultivation method of selenium-rich, zinc-rich and calcium-rich yam in the acidic red soil area of ​​southern China, so as to further improve th...
