Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the embodiments.

[0016] A method for cultivating sweet potato hybrids, comprising the following steps:

[0017] The first step is to keep the lower two stems of the petunias in June, and cut off the rest;

[0018] The second step is to cut sweet potato buds for grafting: cut 10 cm long from sweet potato buds, and then graft;

[0019] The third step is to wrap the leaves of the morning glory: wrap the 10 cm long sweet potato buds with the morning glory grafted from the neighbor;

[0020] The fourth step is to untie the bandaged leaves after 11 or 12 days of survival, water and drain waterlogging; keep 80% of the water on the ground, and drain waterlogging if there is too much water;

[0021] The fifth step is to insert the rod to help it climb and bloom;

[0022] In the sixth step, the grafted flower and the sweet potato flower are artificially pollinated and seeded;

[0023] The seventh st...

Abstract

A sweet potato cross-breeding method comprises the following steps of: in June, remaining two stem branches at the lower part among the stem branches of morning glory, and shearing off the others; cutting off sweet potato buds for grafting; binding by using the leaves of morning glory; watering and draining after survival; inserting a rod so that the morning glory climbs up on the rod and blooms; artificially pollinating the grafted flowers with the sweet potato flowers mutually to fruit; sowing seeds and selecting and beeding good seeds, and sowing the seeds at an interval of 6cm so that seedlings can be transplanted conveniently; after the seeds in the seedbed sprout, transplanting seedlings; after the sweet potatoes are mature, digging the sweet potatoes out; selecting the sweet potatoes with tuberous roots and abandoning those without the tuberous root; breeding the selected tuberous roots next year, selecting good-quality products and abandoning bad ones, and repeating the steps in continuous three years to obtain the good-quality variety. The sweet potato cross-breeding method has the advantages that the grafting process is simple, the cross-bred good-quality varieties are numerous, 8000 varieties (strains) are bred, one hundred of the 8000 varieties are new varieties, and 6 new varieties having unique features are selected out.

Description

technical field [0001] The invention relates to the technical field of hybridization of spinaceae plants, in particular to a hybrid cultivation method of sweet potatoes. Background technique [0002] The existing cassava-sweet potato grafting and hybridization technology has been disclosed for a long time, but the cassava-sweet potato grafting procedure is complicated, and the high-quality varieties cultivated by hybridization are few. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of prior art, the object of the present invention is to provide a kind of sweet potato hybrid cultivation method, grafting procedure is simple, and the high-quality variety of hybrid cultivation is many. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] A method for cultivating sweet potato hybrids, comprising the following steps: [0006] The first step is to keep the lower two stems of th...
