Embodiment 1

[0014] Prepare 60 kg of potato varieties Holland No. 7 and Zihuabai cultivated in the northern Xinjiang area;

[0015] a. Preparation of Sorbus siberia extract: Adopt conventional ethanol Soxhlet extraction method to take 1 kg of branches of Sorbus siberia growing naturally and pulverize to particles with a particle diameter of 3-5 mm, put it in a bottle with a lid, add 4 times the amount The concentration is 95% ethanol, completely soak the crushed particles in ethanol, put it at room temperature for 24 hours, filter the filtrate the next day, add 3 times the concentration of 95% ethanol to the filter residue, and place it in an electric heating constant temperature water bath Extract at 100°C under normal pressure for 8 hours, filter to obtain the filtrate, combine the filtrates, then place the filtrate in a rotary evaporator at a temperature of 50°C to concentrate under reduced pressure and separate ethanol, and dry the concentrate with a drying oven at a temperature of 40°C...

Embodiment 2

[0019] Prepare 60kg each of the potato varieties Holland No. 7 and Zihuabai cultivated in the northern Xinjiang area, and set them aside;

[0020] a. Preparation of Sorbus siberia extract: take 1.5 kg of sorbus siberia branches of natural growth by conventional ethanol Soxhlet extraction and pulverize to particles with a particle diameter of 3-5 mm, put them in a bottle with a lid, and add 4 times the amount The concentration is 95% ethanol, the pulverized particles are completely soaked in ethanol, placed at room temperature for 24 hours, and the filtrate is filtered the next day, and the filter residue is added with 3 times the concentration of 95% ethanol, and heated at the temperature of the electric heating constant temperature water bath. Extract under normal pressure at 100°C for 12 hours, filter to obtain the filtrate, combine the filtrates, then place the filtrate in a rotary evaporator at a temperature of 60°C to concentrate under reduced pressure and separate ethanol...

Embodiment 3

[0024] Prepare 60kg of potatoes Holland No. 7 and Zihuabai cultivated in the northern Xinjiang area, and set them aside;

[0025] a, Preparation of Siberian Sorbus extract: Adopt conventional ethanol Soxhlet extraction method to take 2 kg of naturally grown branches of Siberian Sorbus and pulverize to particles with a particle diameter of 3-5mm, put it in a bottle with a lid, add 4 times the amount The concentration is 95% ethanol, the pulverized particles are completely soaked in ethanol, placed at room temperature for 24 hours, and the filtrate is filtered the next day, and the filter residue is added with 3 times the concentration of 95% ethanol, and heated at the temperature of the electric heating constant temperature water bath. Reflux extraction under normal pressure at 100°C for 18 hours, filter the filtrate, combine the filtrates, place them in a rotary evaporator at a temperature of 55°C to concentrate under reduced pressure and separate ethanol, and dry the concentra...

Abstract

The present invention relates to a potato sprout inhibiting method using Siberian Sorbus pohuashanensis extract. The potato sprout inhibiting method uses Siberian Sorbus pohuashanensis branches and prepares the Siberian Sorbus pohuashanensis extract by conventional method. By spraying the extracts on potatoes, the potato sprouts can be inhibited in the storage time. The Siberian Sorbus pohuashanensis extract is green, environmental, non-polluting and non-toxic, does not pollute fruits and vegetables, human and environment, and is easy to find raw materials. If the extract is made into wettable powder and administrated with other bioinhibitors, the inhibition of potato sprouts would be better. The Siberian Sorbus pohuashanensis extract can not only inhibit potato sprout, but also has a significant inhibitory effect on wheat and barley sprouts. Furthermore, the Siberian Sorbus pohuashanensis extract can effectively prevent mold growth, reduce rot disease incidence. The potato sprout inhibiting method is applicable in region with a drier climate.

Description

technical field [0001] The invention relates to a method for inhibiting potato germination by using Siberian rowan extract, specifically the Siberian rowan (Sorbus sibirica) branch extract has inhibitory effect on potato germination. Background technique [0002] Potato (Solanum tuberosum L) is the third most important food crop in the world and one of the five staple foods in China. my country's planting area is about 80 million mu, with an annual output of more than 83 million tons. It has high nutritional value and strong adaptability, and has been widely valued by government departments because of its increasingly important role in ensuring food security. As a crop for winter storage, the storage period from harvest to long-term consumption should be extended. During this period, potatoes may have a tendency to germinate, which has always been one of the most important problems in the development of the potato industry. This sprouting can lead to a certain degree of sp...
