Problems solved by technology

For example, in the genetic breeding of sweet potato, different materials are intertwined in the field, which seriously interferes with the experimental investigation, and the tuber production cycle of conventional planting is long. The time required is long, resulting in a longer breeding cycle
In addition, in the research on the stress resistance and pest resistance of sweet potato plants, since multiple treatments and repetitions need to be designed in the experiment, if the vines are entangled with each other, not only will the different treatment groups interfere with each other, but also in the investigation of the test results. , takes up a lot of space, and is not conducive to the operation of the test

Embodiment 1

[0029] 1. Cultivation of cuttings explant raw materials

[0030] First of all, the sweet potato seedlings are cultivated in the nursery, and the technology is the same as the conventional seedling method in production. Then, cultivate sweet potato vines suitable for making cutting explants. Cut 18-20 cm strong potato seedlings from the nursery, and plant them in the nursery. When the potato seedling vine grows to a length of 0.4-0.8 meters, the main vine has 2-9 functional leaves, namely The vines can be collected as raw materials for cutting explants.

[0031] 2. Preparation of seedbed for cuttings of explants

[0032] Put a nutrient-rich seedling substrate (Hangzhou Jinhai Agricultural Technology Co., Ltd., Zhe Nong Fei (2011) Zhunzi No. 0044) into a plug with a deeper hole to fully absorb water to a moisture content of 70%-80%, and place it in Reserve in a greenhouse with 24-28 degrees Celsius and humid air.

[0033] 3. Preparation and cutting of cuttings explants

[0034] Cut th...

Abstract

The invention discloses a method for cultivating sweet potatoes. The method comprises the steps that the cirrus of the sweet potatoes is taken and cut to be a cuttage explant comprising stem sections and functional leaves but not a terminal bud; axillary buds of the cuttage explant are removed, then the cuttage explant is placed in a cultivation medium for rooting cultivation in a cuttage mode, and potato seedlings are obtained; the potato seedlings are transplanted to the cultivation medium to be cultivated after seedling hardening; axillary buds on the potato seedlings are prevented from growing all the time in the whole cultivation process. The method is simple, high in resource utilization rate, capable of improving the economic yield of the sweet potatoes, particularly suitable for production of potato seeds and mini sweet potatoes, and capable of improving the accuracy of relative experimental researches on the sweet potatoes and creating peculiar potted plants for viewing and appreciation.

Description

Technical field [0001] The invention belongs to the technical field of agricultural cultivation, and particularly relates to a method for cultivating sweet potatoes. Background technique [0002] Sweet potato is native to tropical Central America. It has strong stress resistance and disease resistance, vigorous growth, high and stable yield, easy to multiply and plant, and has been widely planted in my country. Nowadays, the usable arable land area in my country is gradually decreasing, the cultivation, breeding and physiological research of sweet potato is continuously deepened, agriculture and tourism are booming, and the health food of sweet potato is constantly emerging, so the degree of attention of sweet potato is increasing. [0003] Sweet potato belongs to the sweet potato species of the genus Convolvulaceae [Ipomoea batatas (L.) Lam.], a vine herbaceous plant, annual or perennial, with alternate leaves. When the vine grows to a certain length, it grows evenly on the ground...
