Embodiment 1

[0018] A cultivation method for selenium-enriched, zinc-enriched, and calcium-enriched sweet potatoes, comprising the following main steps:

[0019] 1. When planting, soak the sweet potato stems or tubers 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;

Abstract

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