Method for raising seedlings of edible sweet potato leaves and sweet potato tuberous roots by grafting

Abstract

The invention discloses a method for raising seedlings by grafting edible sweet potato leaves and sweet potato tuberous roots, which is an agricultural innovative technology, and comprises the following specific operations: directly grafting tender shoots of the edible sweet potato leaves as scions to the sweet potato tuberous roots as stocks, and carrying out high-efficiency and low-cost seedling raising and propagation. The method disclosed by the invention not only can be used for seedling raising, propagation expanding and production of edible sweet potato leaf variety cultivation, but also can be used for seedling raising and propagation expanding of edible sweet potato root tuber variety cultivation, the new thought of the grafting technology is broadened, and a new technical army is provided for factory agriculture.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a grafting and seedling raising method for edible sweet potato leaves and sweet potato roots. Background technique [0002] In the field production of edible sweet potato leaves, vine cuttings are generally used to raise seedlings. The first batch of vines for edible sweet potato leaves are cut into a section of about 15cm and cut into the greenhouse seedbed. When the cuttings grow to a certain length, cut 15cm in length for the second batch of cuttings, and at regular intervals, when the vines grow to a certain length, they are cut again for propagation. [0003] At present, the seedbed area of ​​the conventional edible sweet potato leaf seedling raising method needs to be relatively large to meet the needs of field production. In particular, the sweet potato leaves must be marketed early and in large quantities to catch up with the season, and sufficient seedbeds must be prepared to ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the present invention provides a method for grafting and raising seedlings of edible sweet potato leaves and sweet potato tubers to solve the problems in the above-mentioned background technology that the edible sweet potato leaf seedlings require a large area, take up too much land resources, are greatly affected by the climate, and are difficult to multiply. The speed is slow and the cost of seedling cultivation and the quality of seedling cultivation are difficult to balance. At the same time, it can also take into account the cultivation and propagation of edible varieties of sweet potato roots.
