Embodiment 1

[0018] A method for cultivating sweet potatoes in hilly areas, comprising the following steps:

[0019] 1. Variety selection: Xushu 22 was selected as the experimental strain. Xushu 22 was based on Yushu 7 (Nanfeng × Xushu 18) as the female parent, and Sushu 7 (Jishu 10 × AISO122-2) as the parent. Breeding from the male parent.

[0020] 2. Seedling raising: The sowing date is March 10, one and a half months before cutting in the field, and the whole width is 1.5m (including ditch) as a furrow, with a 33cm wide sowing ditch on the furrow, a depth of 18cm, and a furrow distance of 0.6m. Compound fertilizer (potassium sulfate compound fertilizer N: P: K=15%: 15%: 15%) 25kg, 25kg of rapeseed is made base fertilizer. The sowing potatoes are seeded in oblique rows, with the head facing up and the tail facing down, so that the seedlings can emerge neatly. After sowing, cover with plant ash, then cover with fine soil, spray herbicides (Kindur and glyphosate) on the ridge surface, an...

Abstract

The invention discloses a sweet potato cultivation method in hills and mountains, comprising the following steps of: A, selecting variety; B, raising seedlings: the seeding time is in March, the seeded potatoes are oblique in rows with head up and tail down, plant ash is covered after seeding, fine soil is covered, dual gold herbicide and glyphosate are sprayed on the ridges, and mulching film is coated; C, planting: considering that the blocks in hills and mountains have different sizes, micro-ridge single-row planting is adopted, the planting time of spring potato is in April, the planting time of summer potato is in May, the head and the middle of seedlings are cut, oblique planting is adopted, soil is covered, and moisture supply is maintained after planting; D, applying fertilizer: sweet potato is potassium-liking crop and the applied fertilizer is mainly organic fertilizer; and E, intertilling, weeding and earthing up: intertilling has the effect on breathing and is performed after planting, the depth becomes shallow, and weeding and earthing up are combined with intertilling. The method is easy and simple to operate, adopts micro-ridge single-row planting, efficiently uses the soil, causes the seedbed to be insulated, prompts the potato tubers to sprout quickly and abundantly, simultaneously can inhibit occurrence of black spot, and increases the yield by 20-30%.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and more specifically relates to a method for cultivating sweet potatoes in hilly and mountainous areas. The method can utilize idle hilly and mountainous areas to plant sweet potatoes, thereby greatly increasing the yield per unit area of ​​sweet potato planting and promoting the development of sweet potato agricultural industrialization. The invention is suitable for the production and cultivation of sweet potatoes in hilly and mountain areas, and is also suitable for popularization and application of sweet potato production in southern mountainous areas. Background technique [0002] The sweet potato planting area in Hunan Province is about 300,000 hm 2 In the past, due to the single variety of sweet potato, serious degradation, improper operation of farmers' cultivation techniques, insufficient power to invest in field management, and reduced land output rate, the yield of sw...
