Potato germination inhibitor and preparation method thereof

Abstract

The invention discloses a potato germination inhibitor. The inhibitor is prepared from raw materials in parts by weight as follows: 1-50 parts of a loss control regulator, 1-300 parts of modified silicone oil and 650-998 parts of water, wherein the loss control regulator is prepared from aminated attapulgite and micro-nano biosilicon / carbon through mixing in the mass ratio being (3-5):(1-2). The invention further discloses a preparation method of the potato germination inhibitor. The potato germination inhibitor and the preparation method thereof have the advantages as follows: (1) the preparation method is simple, convenient to operate and low in cost and allows mass production; (2) the nanocomposite prepared from attapulgite, modified silicone oil and other materials is sprayed on potatoes, a netted nano protection layer can be formed through self-assembly, moisture is isolated effectively, the germination rate is reduced, and the storage time of the potatoes is prolonged; the product is natural, green, environment-friendly and safe, has no side effects and can reduce the germination rate of the potatoes by 80%-95% and effectively guarantee the yield and quality stability of the potatoes.

Description

technical field [0001] The invention relates to the technical field of ecological agriculture, in particular to a potato germination inhibitor and a preparation method thereof. Background technique [0002] Potato is one of the most important grain and vegetable dual-purpose crops in the world. It has become the fourth largest food crop in my country after corn, rice and wheat. China is the largest producer of potatoes, accounting for about 1 / 4 of the world in both area and output. Most of the potato tubers in the main producing areas in the north have to be stored for 3-6 months after harvesting, and the potato tubers after harvest will germinate and green after a few months of dormancy. The loss caused by germination, browning, and turning green when exposed to light is 18-20%, and can reach 40-50% in serious cases. [0003] Germination is the main cause of potato storage loss, which will lead to the loss of potato nutrition and affect the commodity quality of tubers. If...

Problems solved by technology

[0003] Germination is the main cause of potato storage loss, which will lead to the loss of potato nutrition and affect the commercial quality of tubers. If the seed potato sprouts grow too long, it will also affect the emergence of seedlings. Especially after potatoes germinate, there will be a lot of solanine around the bud holes. This is a neurotoxin that inhibits the respiratory center and poses a huge safety hazard to consumers

The germination of potatoes during storage leads to the loss of various nutrients and reduces the utilization value of potato tubers for fresh food, food processing and industrial processing

[0004] Chemical bud inhibitors such as CIPC (chlorphenamine) can play a good bud suppression effect, but it has mutagenic and carcinogenic effects on animals and plants, and will seriously affect the activity of potato seed potatoes, thereby affecting the growth of potato buds, At present, chemical sprout inhibitors have been banned or will be banned by developed countries such as the United States, Japan, and Australia
