The method of planting and multiplying seedlings for many years in a sweet potato nursery

Abstract

The invention provides a method of multi-year seedling producing and collecting by one-time planting of a sweet potato nursery. The method comprises the steps of planting in the nursery, building a greenhouse and circularly managing the sweet potato nursery at a plurality of times; the step of circularly managing the sweet potato nursery at a plurality of times involves the greenhouse period, the seedling collecting and planting period, and continuous growing and utilizing period of the seedlings. According to the method, the growth utilization period of the sweet potato seedlings in the nursery is prolonged, rather than removing the bed seedlings, according to germination habits of the sweet potato when the sweet potato seedlings cultivated in the nursery of various types meet the requirement on planting in spring and summer of the current year, then the seedlings can continuously grow in the bed, and the management is improved to continuously cultivate strong seedlings; the seedlings are cultivated and collected and planted in a large land or used for other proposes year after year; therefore, a novel way for collecting the sweet potato seedlings by one-time planting is created.

Description

technical field [0001] The present invention relates to a method for raising sweet potato seedlings, in particular to a method for planting and multiplying seedlings for many years in a sweet potato nursery. Into the nursery, the method of raising seedlings for many years to use seedlings. Background technique [0002] At present, sweet potato seedlings have potato root seedling raising method in early spring, stem vine or potato root greenhouse overwintering seedling raising method, summer potato picking nursery method and so on. These seedling raising methods do not make full use of the strong germination habit and regeneration ability of sweet potato. They all build seedlings every year for planting in the field. They cannot implant sweet potato breeding materials into the nursery at one time, reproduce potato seedlings continuously, and realize the use of seedlings for many years. There is the defective of labor-intensive and material-intensive. Contents of the invent...
