Embodiment 1

[0023] A kind of cultivation method of Longshu No. 9 poison-free sweet potato, concrete steps are:

[0024] (1) Land preparation and ridging:

[0025] Carry out intensive plowing and ridge planting on the potato field; before winter, apply 2600kg of organic fertilizer per mu, plow 31cm deep, and harrow and grind to preserve moisture; Ridge, ridge width 70cm, height 30cm, plant 1 row of sweet potatoes on the ridge;

[0026] (2) Seedling selection and cultivation:

[0027] Select seedlings with a seedling age of 31 days, bright green leaves, large and thick leaves, thick and short stems, strong and disease-free seedlings for cuttings; when transporting virus-free potato seedlings, use mud strips to protect virus-free potato seedlings More water will be lost, and at the same time, it is necessary to pack, handle and transport lightly to protect the virus-free seedlings from damage; the selected virus-free potato seedlings are cultivated according to seasonal changes and tempera...

Abstract

The invention relates to a cultivation method of 'Longshu 9' virus-free sweet potatoes. The method comprises specific steps as follows: intensive farming is performed in a field of the sweet potatoes, ridging and planting are performed, and one row of the sweet potatoes are planted on a ridge; strong seedlings which have bright green, large, thick and fat leaves, thick stems and short sections and are healthy and free from diseases and pests are selected for cuttage; the selected virus-free sweet potato seedlings are cultivated according to season change and temperature change; scientific cuttage is performed; inspection and replanting of the seedlings are performed after cultivation; intertillage and weeding are performed after the sweet potato seedlings survive and before the seedlings get plump, chemical control is performed when the sweet potato seedlings cover the land tightly after cultivation, as for the field with flourishingly-growing sweet potatoes, flourishing growth can be controlled in combination of weeding and vine lifting, and the seedlings cannot be turned during vine lifting; the sweet potatoes are harvested when the ground temperature is reduced to 13-14 DEG C, and seed sweet potatoes are reserved; a sweet potato cellar is cleaned before storage, timely ventilation and heat dissipation are performed in the early period of storage, thermal insulation and cold prevention work are made in the middle and later periods, and fresh air is kept in the storage period. By means of the provided cultivation method of the 'Longshu 9' virus-free sweet potatoes, good economic benefits are gained in production, and the average yield is increased by about 30%.

Description

technical field [0001] The invention relates to the field of sweet potato cultivation, in particular to a cultivation method of Longshu No. 9 virus-free sweet potato. Background technique [0002] Longshu No. 9 virus-free sweet potato has good germination, vigorous growth of stems and leaves, early tuber formation, neat and concentrated tubers, high yield, high quality, storage resistance, good commodity properties, and high economic benefits. And once the process of cultivating Longshu No. 9 virus-free sweet potatoes is not properly controlled, the yield of sweet potatoes will also be reduced, which will not only waste seedlings, but also bring great economic losses to farmers. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a cultivation method of Longshu No. 9 virus-free sweet potato. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A k...
