Regulator for increasing rice dietary fibers and application thereof

Abstract

The invention discloses a regulator for increasing rice dietary fibers and application thereof, and belongs to the technical field of crop regulators, the regulator comprises the following components by mass: 8-15% of a growth regulator, 3-6% of an organic matter, 1-3% of an inorganic salt, and the balance of water, totaling 100%; wherein the growth regulator is selected from at least one of compound sodium nitrophenolate, ethephon, chloromethylsilatrane, forchlorfenuron and diphenylurea sulfonic calcium; the organic matter is selected from at least one of chitin and compound amino acid; the inorganic salt is selected from at least one of magnesium sulfate, ferrous sulfate, potassium chloride, calcium nitrate, borax and potassium silicate; the invention further discloses a preparation method and application of the regulator. By applying the regulator, the dietary fiber content and disease resistance of rice can be remarkably improved, accumulation of reactive oxygen species (ROS) and callose of rice leaves can be promoted, and finally the purpose of reducing application of chemical fertilizers and pesticides is achieved.

Description

technical field [0001] The invention relates to the technical field of crop regulators, in particular to a regulator for increasing rice dietary fiber and its application. Background technique [0002] The World Health Organization and the international nutrition community have proposed that the minimum warning line for adults' daily dietary fiber intake is 27 grams; my country Nutrition Society pointed out that the daily dietary fiber intake for adults is 30.2 grams. The survey shows that the region with the highest dietary fiber intake in China is 13.3 grams, and the lowest region is 8.6 grams, which shows that the daily dietary fiber intake of Chinese residents, especially those in economically developed areas, is seriously insufficient. Especially in the southern region where rice is used as the staple food, the dietary fiber content of ordinary rice is generally only about 0.6%, which is one of the important reasons for insufficient dietary fiber intake. Because increa...

Problems solved by technology

[0003] At present, the method of increasing the dietary fiber of rice is generally to reprocess the rice. For example, the Chinese patent application with the application number 201810854010. 201711441265.5, Chinese patent application titled "A High-Fiber Rice Rich in Dietary Fiber". Although these methods can increase the content of dietary fiber in rice, they all belong to the reprocessing of rice. On the one hand, these methods are costly , on the other hand, the processing is also complicated, which is not conducive to popularization and application
