[0068] Embodiment 1: The present invention reduces the cultivation method of potato tuber glycoalkaloid content

[0069] The implementation steps of this embodiment are as follows:

[0070] A. Pretreatment

[0071] 20 days before sowing, put the first-class potato seed Zhongshu No. 20 at room temperature for germination; at the same time, in the first ten days of March, the soil was rotary tilled at a depth of 25cm, and the soil particles were fine and uniform without any other plant residues. thing;

[0072] B. Sowing

[0073] In the first ten days of April, the germinated and disease-free seed potatoes were cut into seed potato pieces with 2 to 3 bud eyes; at the same time, the pretreated rotary tillage land in step A was planted with shallow ditches, and the row spacing of the planted shallow ditches was It is 58cm, depth 10cm; Put the described seed potato block according to planting distance 30cm in the planting shallow ditch, then apply the refined organic fertilizer ...

Abstract

The invention relates to a cultivation method for reducing the glycoalkaloid content of potato tubers. The method comprises the steps of pretreatment, sowing, covering soil and ridging, covering blackfilms on ridges, covering soil on the films and the like. The glycoalkaloid content of potato tubers is reduced by adopting a cultivation technology. The cultivation method for reducing the glycoalkaloid content of potato tubers provided by the invention has the advantages of avoiding the emergence of green-head potatoes during the planting process, and improving the appearance quality and ediblesafety of the potato tubers.

Description

【Technical field】 [0001] The invention belongs to the technical field of crop cultivation. More specifically, the present invention relates to a cultivation method for reducing the content of glycoalkaloids in potato tubers. 【Background technique】 [0002] Glycoalkaloids are secondary metabolites that enhance potato resistance to biotic and abiotic stresses. However, when potatoes containing glycoalkaloids are eaten or fed, glycoalkaloids are toxic. For example, in fresh potatoes eaten by humans, if the total glycoalkaloids of potato tubers exceed 20mg / 100gFW, people will be poisoned, so It is particularly important to ensure the food safety of potato tubers. Especially in recent years, the potato production in the south has grown rapidly. Due to the frequent drought in the potato cultivation season in the south, it will cause cracks on the soil surface, so that the tubers growing in the soil are often exposed to sunlight, resulting in a large number of green potatoes harv...
