Planting method of edible sweet potato

Abstract

The invention provides a planting method of edible sweet potato, comprising: selecting strong seedlings, preparing a land, applying fertilizers, ridging, transplanting seedlings of sweet potato, perforating mulching film, carrying out positional oblique planting, carrying out drip irrigation before and after transplanting, managing a field, disinfecting, weeding, providing chemical control, picking leaves twice, harvesting tubers of sweet potato, and storing the tubers. The planting method has the advantages that the great ridge height allows the activity range to be widened for roots and tubers of sweet potato and the day-night temperature differences of soil at the ridges to be increased; the great ridge spacing helps increase photosynthetic efficiency of leaves and reduce competition ofunderground tubers for nutrition; performing the mulching film to carry out positional transplanting of the seedlings of sweet potato helps increase the survival rate of the seedlings and increase the yield of sweet potato; drip irrigation tapes spread among the ridges for drip irrigation ensures sufficient moisture; field management, pest and disease prevention and chemical control management help increase the yield of sweet potato.

Description

technical field [0001] The invention belongs to the technical field of sweet potato planting, and in particular relates to a planting method of edible sweet potato. Background technique [0002] At the beginning of the 21st century, the National Agricultural Technology Extension Service Center (2004) formulated and promulgated the National Variety Test Management Measures (Trial) and the National Sweet Potato Variety Identification Standards (Trial). In 2008, the basis for subdividing sweet potato varieties The standards for the identification of sweet potato varieties have been revised, and the appearance attribute indicators of edible varieties have been strengthened, requiring no grooves and no cracks in the potato pieces, and smooth potato skins. Since the beginning of the 21st century, fresh sweet potatoes have developed from the front end of breeding to the end of production and consumption, from the original focus on quality and output to the enjoyment of the senses s...

Traditional sweet potato planting adopts the cultivation method of sowing first and then covering, small ridge single row or large ridge double row planting, the traditional way of sowing first and then covering with film, the traditional method of planting seedlings in time will cause the seedlings to be burned under the high temperature film, and The temperature is low in spring, and the emergence rate of sweet potatoes after sowing is low. Small ridges are planted in single rows or large ridges in double rows. The phenomenon of big seedlings bullying small seedlings, and tubers have grown to both sides at the same time, which affects mechanical harvesting
