Embodiment Construction

[0022] In the middle and late April of each year, cut the potato seedlings in the sweet potato seedling bed to grow seedlings with a length of 18-25cm, pack them into bags, avoid direct sunlight, keep the ambient temperature between 25°C-40°C, and put In a humid environment, after 2-3 days new roots can be transplanted into the field; or in the first ten days of June, cut the potato vines of the second stage of seedling cultivation in the field to a length of 18-25cm, and cut the lower part of the potato vines 10-12cm Cut off the petioles below, pack them into bags, avoid direct sunlight, keep the ambient temperature between 25°C and 40°C, place 1-2cm of the roots of the seedlings in a humid environment, and move them after 2-3 days after new roots grow. Planted in the field; the potato seedlings after rooting are untied and scattered in 10-20cm deep water to ensure the moisture content of the potato seedlings and to take them easily.

Abstract

The invention discloses a root growing and high-yield cultivating method of sweet potato seedlings. The method comprises the following steps of during root growing, cutting 18-25cm of sweet potato seedling in a sweet potato seedling bed, bundling, packaging, soaking 1-2cm of seedling root in a wet environment, maintaining the environment temperature at 25-40 DEG C, growing new roots after 2-3 days, and then transplanting to the field; during cultivating, after conventional cultivating, manufacturing a groove with 3-5cm depth at the edge of a sweet potato cavity, bending the upper part of the sweet potato seedling into the groove, covering the soil on the groove, exposing the head of the sweet potato seedling during soil covering, and fully watering at the upper part. The sweet potato seedling bred by the root growing method has the advantage that after second breeding, the survival rate of sweet potato seedling during cultivating can reach 99%, various types of cultivating are met, and the sweet potato vine in the edge groove can generate the root system again; as the sweet potato seedling is close to the soil surface, the light intensity is sufficient, the growth of root and stem is strong, is well developed, and expands to the deeper layer, the fruiting time of sweet potato is early, the sweet potato is large, and the yield is improved by more than 30% than the yield of traditional direct inserting method.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for promoting rooting and high-yield cultivation of sweet potato seedlings. Background technique [0002] At present, sweet potato cultivation has spring planting and summer planting. How to improve the survival rate and high-quality and high-yield of sweet potato cultivation, one is good varieties, the other is good methods, and the third is early planting and quick work. [0003] Sweet potato seedlings generally germinate on the seedbed and grow to a certain height before transplanting after cutting off the black spots on the roots. However, during the transplanting process, it is easy to die, lack seedlings, etc., and the survival rate is not high. The impact of unreasonable methods on yield is also crucial. Some rhizomes in direct planting do not agglomerate, and the yield is low, which is easy to cause holes. Contents of the invention [0004] In order to im...
