Embodiment 1

[0026] Present embodiment relates to a kind of high-yield cultivation method of sweet potato, comprises the following steps:

[0027] (1) Selection of potato seeds and treatment of potato seeds: select potato pieces that are free from pests, no damage, moderate in size, correct in shape, smooth in potato skin, and not damaged by freezing, and soak in carbendazim solution for 30 minutes , take it out, dry it, and set aside;

[0028] (2) Seedbed preparation: choose leeward and sunny, well-drained, low groundwater, flat, loose and fertile, and germ-free sandy loam as the seedbed, apply mixed fertilizers, carry out deep plowing, and dig seedling pits with a depth of 20 cm and a length of 20 cm. 2 meters, 1 meter wide, then first pave a 3 cm thick attapulgite clay layer at the bottom of the pit, and then spread a 2 cm thick pine needle soil layer for subsequent use;

[0029] (3) Sowing: Arrange the sweet potato seeds treated in step (1) evenly in the seedling pit, spray disinfecta...

Abstract

The invention discloses a high-yield cultivation method for sweet potatoes. The high-yield cultivation method includes steps of (1), selecting and treating potato seeds, to be more specific, selectingpotato pieces to be used as the seeds, soaking the potato seeds in carbendazim solution, taking the potato seeds out of the carbendazim solution and airing the potato seeds for standby application; (2), sorting seedbeds, to be more specific, selecting sandy loam to be used as seedbed lands, applying mixed fertilizers, carrying out deep plowing, digging seedling growing pits, laying attapulgite clay layers at the bottoms of the pits at first, and then laying pine needle soil layers in the pits; (3), sowing the seeds, to be more specific, uniformly arranging the sweet potato seeds in the seedling growing pits, spraying disinfection fluid, watering the sweet potato seeds and covering the potato growing pits with mulching films; (4), carrying out seedling growing management, to be more specific, allowing the temperatures of the seedling growing pits to be 30-35 DEG C under the control at first, keeping the temperatures unchanged for 5-8 days, then cooling the seedling growing pits to allow the temperatures to reach 25-30 DEG C until seedlings emerge, allowing the seedlings to grow until the lengths of the seedlings reach 10 centimeters, exercising the seedlings until the lengths of the growing seedlings reach 20 cm, and dividing and transplanting plants; (5), carrying out transplanting; (6), carrying out field management; (7), harvesting the sweet potatoes, to be more specific, digging pits and harvesting the sweet potatoes. The high-yield cultivation method for the sweet potatoes has the advantages that the high-yield cultivation method is high in breeding emergence rate andseedling survival rate, and the sweet potatoes are high in yield and have good taste.

Description

technical field [0001] The invention belongs to the technical field of sweet potato planting, and in particular relates to a high-yield cultivation method of sweet potato. Background technique [0002] Sweet potato is a favorite food for people in our country, especially in northern China, people like to eat sweet potato. However, although the planting area of ​​sweet potato in my country is relatively wide, the yield of sweet potato per mu is relatively low. Therefore, in order to improve the cultivation of sweet potato The income of personnel needs to improve the cultivation method of existing sweet potato. Contents of the invention [0003] The present invention provides a high-yield cultivation method for sweet potatoes, which solves the problems in the background technology above. The high-yield cultivation method for sweet potatoes has a high seedling emergence rate, a high seedling survival rate, high yield and good taste of sweet potatoes. [0004] In order to solv...
