Problems solved by technology

But this method is labor-intensive, time-consuming, and seed potato-intensive, and the storage technology in winter is not easy to master, which will affect the reproduction in the next year, and it is difficult to cultivate strong seedlings with high survival rate and high quality.

Embodiment 1

[0029] A kind of sweet potato seedling raising method with high survival rate, the concrete steps are as follows:

[0030] (2) Selection of seedbeds:

[0031] (1) Construction of seedbed: choose leeward and sunny, flat terrain, good drainage, low groundwater level, and plots that have not been planted with sweet potatoes and have been used as seedbeds for at least 2 years as seedbeds. ~50cm, the length depends on the size of the transplanting area, the bottom of the bed is deep in the south, shallow in the middle, and slightly deeper in the north, forming an inverted trough shape with high middle and low surrounding;

[0032] (2) Filling the brewing material: The brewing material should be made of non-mold straw and unfermented cow, horse and sheep dung. Mix evenly according to the ratio of 1 part of straw and 1 part of dung, pour warm water, and then brew the fermented material. The water content is between 60% and 80%. Then, cover it with a film, and seal it with mud around...

Embodiment 2

[0048] A kind of sweet potato seedling raising method with high survival rate, the concrete steps are as follows:

[0049] (3) Selection of seedbeds:

[0050] (1) Construction of seedbed: choose leeward and sunny, flat terrain, good drainage, low groundwater level, and plots that have not been planted with sweet potatoes and have been used as seedbeds for at least 2 years as seedbeds. ~50cm, the length depends on the size of the transplanting area, the bottom of the bed is deep in the south, shallow in the middle, and slightly deeper in the north, forming an inverted trough shape with high middle and low surrounding;

[0051] (2) Filling the brewing material: The brewing material should be made of non-mold straw and unfermented cow, horse and sheep dung. Mix evenly according to the ratio of 1 part of straw and 1 part of dung, pour warm water, and then brew the fermented material. The water content is between 60% and 80%.

Abstract

The invention provides a high-survival-rate sweet potato seedling raising method. The high-survival-rate sweet potato seedling raising method comprises the following concrete steps: (1) seedbed selection; (2) seed selection and potato arrangement; (3) seedbed management; and (4) seedling collection. According to the invention, through reasonable seed potato treatment and seedbed arrangement, the germination rate and the tidiness rate of sweet potatoes are effectively increased; seed potatoes are subjected to coating pretreatment one day before seed metering, so the activity of germination acceleration is improved, and germination and growth at a later period are easily promoted; meanwhile, good sterilization and heat preservation performances are achieved; the periods of seed metering andgermination acceleration are significantly shortened; high germination rate and rapid bud emergence are realized; bud seedlings are healthy and strong; and the survival rate of seedlings after being transplanted is greatly increased.

Description

technical field [0001] The invention relates to the technical field of sweet potato cultivation, in particular to a sweet potato seedling raising method with high survival rate. Background technique [0002] Sweet potato, also known as sweet potato and artichoke, is an annual or perennial creeping herb. It not only has high yield, strong drought resistance, but also is rich in nutrients, rich in dietary fiber, carotene, vitamins and various trace elements. It is known as the king of anti-cancer At the same time, sweet potatoes also have huge economic value. They can process vermicelli, flour noodles, vermicelli and caramel, extract citric acid, convert ethanol, etc., which play a major role in improving people's lives and developing commodity economy. The key to high yield of sweet potatoes is to cultivate well Seedlings, only when the strong seedlings are planted early can they lay a good foundation for high yields and good harvests. The standard for strong sweet potato see...
