Method for cultivating fresh-eaten type sweet potatoes with high quality and high yield

Abstract

The invention provides a method for cultivating fresh-eaten type sweet potatoes with the high quality and the high yield. The method comprises the steps that a series of technical means such as land selection, organic fertilizer application, ridging, drip irrigation belt laying operation, black mulching film coating operation, transplantation and drip irrigation and fertilization under a mulching film are adopted and field management is enhanced. The problems that in the growth process of the sweet potatoes, seedling survival in the earlier stage is slow, the overground parts grow over fast in the middle stage, the sweet potatoes lose fertilizer and fail early in the later stage, the agricultural chemical use amount is large, the yield of the sweet potatoes is low, and quality is poor are solved and coordination and unification of the high yield and the high quality of the fresh-eaten type sweet potatoes are achieved.

Description

technical field [0001] The invention belongs to the technical field of cultivation methods, and in particular relates to a high-quality and high-yield cultivation method for fresh-eating sweet potatoes. Background technique [0002] China is the largest producer of sweet potatoes in the world, and its planting area and total output account for about 65% and 85% of the world's total area and total output, respectively. In recent years, with the improvement of people's living standards, the awareness of health care has become stronger and stronger. Sweet potato has changed from a food crop to a cash crop, and has gradually become a health food that adjusts taste and enriches the vegetable basket in life.
