Embodiment 1

[0043] A kind of sweet potato water seedling cultivation method, such as Figure 1-6 shown, including the following steps:

[0044] (1) Embed sweet potatoes in nutrient soil to accelerate seedlings and grow. When the tender buds grow to 6-7 vine nodes, cut the vine nodes and inoculate them in the vertical seedling rack in the nursery room for hydroponic dense planting; wherein the seedling room The temperature is set at 25-31°C, and the water used in the hydroponics is circulating water containing nutrient solution;

[0045] (2) The clipped vine nodes include 1-2 vine nodes and at least 1-2 leaves; the clipped vine nodes are planted in a three-dimensional seedling stand at 26-31°C for 15-25 days in hydroponic close-knit, get rooted vines;

[0046] (3) In the step (2), the rattan seedlings after dense planting and rooting are transplanted into the soil.

[0047] Specifically, in step (1), high-quality, healthy sweet potatoes with more germination points are selected as seed ...

Abstract

The invention discloses a sweet potato hydroponic seedling raising method, and belongs to the field of seedling raising. The method comprises the following steps: burying sweet potatoes into nutrient soil to promote seedlings and grow, when tender shoots grow to have 6-7 rattan joints, shearing the rattan joints, inoculating the rattan joints into a three-dimensional seedling raising frame in a seedling raising room, and carrying out hydroponic close planting, wherein the temperature of the seedling raising room is set to be 25-31 DEG C, and water adopted in water culture is circulating water containing a nutrient solution; and transplanting the rattan seedlings which are densely planted and rooted into soil. According to the method, a soil culture and water culture mode is adopted for the sweet potatoes, water culture is carried out under the specific temperature and humidity, the seedling culture speed can be greatly increased, and the seedling culture amount is increased. The three-dimensional seedling raising frame is adopted, the three-dimensional seedling raising frame can be rapidly placed and fixed, and operation efficiency is improved. By circulating the water containing the nutrient solution, nutritional ingredients in the water can be fully utilized, the water quality can be improved, oxygen in the water can be supplemented in time, rootstocks are prevented from being rotted, root growth is promoted, and seedling raising is accelerated.

Description

technical field [0001] The invention relates to the field of seedling cultivation, in particular to a method for cultivating sweet potato seedlings in water. Background technique [0002] Sweet potatoes are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. They have the reputation of "longevity food" and their sugar content reaches 15%-20%. It has anti-cancer, heart protection, prevention of emphysema, diabetes, weight loss and other effects. [0003] Sweet potatoes generally use tubers to grow seedlings. Sweet potato tubers generally start to germinate after the weather warms up in spring. After germination, they are buried in the soil for accelerated germination and seedlings. However, soil seedling cultivation time is fixed. In most areas, seedlings are planted in spring and harvested in summer and early autumn. Only one season can be sown a year, which shortens the supply time of sweet potatoes. Therefore, greenhouse planting is the...
