Embodiment 1

[0020] A high-yield cultivation method for planting sweet potatoes in summer and autumn, the concrete steps comprising:

[0021] (1) Selection of high-quality varieties: The varieties planted in Guangdong mainly include Guangzishu No. 1, Guangshu 98, and 87 newly bred by the Crop Institute of Guangdong Academy of Agricultural Sciences in recent years. After trial planting, it shows that the yield is high, the potato shape is well expanded, and the yield per unit area can exceed 30t / hm 2 ;

[0022] (2) Cultivate high-quality and strong seedlings: select high-quality potato pieces as seed potatoes, and carry out potato seedling cultivation from mid-to-late March to early April. The seedbed is 1.2m wide, with deep trenches and high borders, and the interval between potato pieces is 10cm. After the seed potatoes are arranged, they are covered with soil 5cm, after watering, cover with a layer of rice straw to keep warm and prevent weeds to promote seedling emergence. Seed potatoes...

Abstract

The invention relates to a high-yield cultivation method of planting sweet potatoes in summer and autumn and belongs to the technical field of agricultural product planting. The high-yield cultivation method of planting the sweet potatoes in summer and autumn comprises the specific steps: selecting high-quality varieties and cultivating high-quality strong seedlings in March and April; selecting a suitable field, carrying out soil preparation, ridging and applying fertilizers; planting at the end of July and the beginning of August, and carrying out single-plant planting, wherein the planting row spacing is 15-20cm and the planting density is 45000-60000 plants / hm<2>; and after transplanting, carrying out field management at an early stage, a middle stage and a later stage. The high-yield cultivation method of planting the sweet potatoes in summer and autumn is simply described in the aspects of variety selection, seedling culture, plot selection, soil preparation and ridging, planting, field management, prevention and control of plant diseases and insect pests, harvesting and the like of the sweet potatoes, and reference is provided for cultivating the sweet potatoes in summer and autumn in Guangdong areas.

Description

Technical field [0001] The present invention involves a method of cultivation of sweet potatoes, which specifically involves a high -yield cultivation method of planting sweet potatoes in summer and autumn, which belongs to the field of agricultural product planting technology. Background technique [0002] Sweet potato, also known as sweet potatoes, sweet potatoes, sweet potatoes, etc., belongs to the family of sweet potato, which is a sweet potato species, which is a raw herbaceous plant in the year.Sweet potato is high -temperature and strong sunlight. According to the test, the accumulation temperature of ≥15 ° C during the birth period is above 1000 ° C, and the birth period is more than 100 ~ 120d.Because the temperature in summer and autumn is from high to low, the amount of rainfall from to less, the entire fertility period is sufficient, the solar radiation energy is large, the effective accumulation temperature is large, the temperature of the middle and the middle of t...
