Description

A kind of potted sweet potato cultivation method

technical field

The invention relates to the technical field of potted plants, in particular to a potted sweet potato cultivation method.

Background technique

Ornamental potted plants refer to the general term for living plants that have specific ornamental value and are planted in flowerpots. Ornamental potted plants are evolved from traditional Chinese garden art. Along with the raising of people's living standard, it has become a kind of life fashion to plant the potted plants of ornamental plants in the office or at home or on the balcony to pursue individualized natural beauty. Plant potted plants usually take plants as the main body, supplemented by stones, grass, moss and ornaments, imitating the shape of natural plants, adding artistic processing such as pruning and pruning, to shape the natural beauty of plants in the pot, and achieve the artistic effect of seeing the big from the small.

With the development of modern biotechnology, the diversity of sweet potato varieties is becoming more and more abundant. Some sweet potato varieties have strange leaf shapes and bright colors, and the color of leaves can change significantly during the growth process, which is very suitable for making ornamental potted plants. . Because the sweet potato material is cheap to purchase and the sweet potato itself has strong stress resistance, the ornamental potted plants made of sweet potato have the advantages of low cost, simple management and unique shape, which are very suitable for people to decorate their rooms and offices. But there are very few reports about the potted cultivation of sweet potato at present.

Ningzishu No. 4 is a fresh-eating purple sweet potato variety selected by the Jiangsu Academy of Agricultural Sciences. Mature leaves are green, and the plant itself has a strong ornamental value, so it is suitable as an ornamental potted potato.

(1) Preparation: Choose Ningzishu No. 4 potato cubes that are moderate in size, beautiful in shape, healthy and disease-free, and have no scars on the surface. Carefully clean the surface of the sweet potato with a soft brush, and try not to damage the potato skin during the cleaning process; It is necessary to choose a small flower pot with beautiful appearance, moderate size, and openable drainage holes on the bottom or side, and fill it with a certain amount of sand and water, and the water surface should not be higher than the surface of the sand;

(2) Insert the top and bottom of the sweet potato block into the flowerpot vertically or at a certain angle (45-90°C), and the insertion depth is preferably 30-50% of the vertical height of the sweet potato;

(3) Place the flower pots filled with sweet potatoes in a light incubator to cultivate and accelerate germination. The culture conditions are constant temperature 28°C and light time 8 hours/day. During this period, pay attention to the amount of water in the flower pots and replenish water in time;

(4) After about 12 days of cultivation, Ningzishu No. 4 potato cubes began to germinate. When the potato seedlings grow to a height of about 15cm, move the potted plants out of the light incubator and place them on a window sill that can be exposed to sunlight. Supplement the nutrients needed for plant growth;

(5) When the potato seedlings grow to more than 30cm, the potato seedlings will hang down due to insufficient support. At this time, the stem tip can be cut off to promote the growth of its side branches, and a small amount of thin iron wire or thin wooden sticks can also be inserted into the flower pot. Use strings to assist in fixing the stems and vines for modeling, so that the plants grow into a shape that conforms to your own design;

(6) If the plant grows too vigorously, the plant can be sprayed with paclobutrazol 10% wettable powder 500 times liquid to inhibit its growth;

(7) If you want the plant to bloom, you can perform short-day treatment (6-8 hours of light/day) until it blooms.

(8) If there is whitefly damage during plant growth, it can be controlled by spraying 2000-3000 times of 5% imidacloprid EC.

After three months of cultivation, the potted plants grow vigorously and have strong ornamental value.

Example 2 Using the potato block of the sweet potato variety "Guangshu 87" as the main material to make ornamental potted plants

Guangshu 87 is a fresh-eating sweet potato variety bred by Guangdong Academy of Agricultural Sciences. The plant of this variety is semi-erect, the leaves are deeply notched, the top leaves are green, and the veins are reduced to purple. The plant itself has strong ornamental value , suitable as an ornamental potted potato.

In order to prove the beneficial effect of the present invention, the applicant has also carried out following test, specifically as follows:

Contrastive experiment using pastoral frozen soil and non-pastoral frozen soil

Under the same conditions of other cultivation substrate formula components and cultivation conditions, adopt the cultivation substrates of pastoral frozen soil and common non-pastoral frozen soil to plant 10 pots of sweet potatoes, and the length, width and height of the flower pots are respectively 40cm, 25cm and 15cm, and then the Its unified management and management conditions are exactly the same. The comparison results are shown in Table 1.

Table 1

It can be seen from Table 1 that the average emergence time of sweet potatoes cultivated in the pastoral permafrost substrate is 5 days shorter than that in the non-pastoral permafrost substrate, the average emergence of single potato is increased by 60%, and the average vine length of 30 days after emergence is increased. 47.4%, the average number of leaves at 30 days after emergence increased by 50%, and the biomass at 30 days after emergence increased by 45.6%. It can be seen that the use of pastoral permafrost substrates can promote the growth of potted sweet potatoes.

Although the present invention has been described in detail with general descriptions and specific examples above, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, the modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the protection scope of the present invention.
