High-yield planting method for purple sweet potatoes

Abstract

The invention discloses a high-yield planting method for purple sweet potatoes. The high-yield planting method comprises the following steps of 1 purple sweet potato vine treating; 2 planting field treating; 3 purple sweet potato vine cutting; 4 field managing; 5 harvesting. According to the high-yield planting method, purple sweet potato vines are fully utilized, one part of the purple sweet potato vines is used for cutting seedling preparation, the other part of the purple sweet potato vines is used as fertilizer components, a new way is supplied to reutilization of the purple sweet potato vines, and the environment is protected; the cost is lower, cultivated purple sweet potatoes are high in yield and good in quality, and the very good economic benefit and popularization value are achieved.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a high-yield planting method of purple sweet potatoes. Background technique [0002] Purple sweet potato has attracted much attention because it is rich in anthocyanins and other health-care substances for human nutrition. It can be eaten fresh, extracted from pigments, processed into whole powder, and processed as snack food. The market demand is strong and the planting efficiency is high. The current planting of purple sweet potatoes has the following disadvantages: using seed potatoes to bury seedlings, and then cutting and planting purple sweet potato seedlings will consume a large amount of seed potatoes, the cost of planting is large, and it takes a lot of work and time; people in order to obtain higher yields However, if a large amount of ordinary inorganic fertilizers are applied, the fertilizer utilization rate is low, and long-term use will cause soil compaction and ...

The current planting of purple sweet potatoes has the following disadvantages: using seed potatoes to bury seedlings, and then cutting and planting purple sweet potato seedlings will consume a large amount of seed potatoes, the cost of planting is large, and it takes a lot of work and time; people in order to obtain higher yields However, if a large amount of ordinary inorganic fertilizers are applied, the fertilizer utilization rate is low, and long-term use will cause soil compaction and a decrease in yield; after the purple sweet potato is harvested, a large number of purple sweet potato vines will remain. At present, the reuse of purple sweet potato vines is limited and cannot be fully utilized. its value, resulting in a waste of resources
