Selenium-rich seed-soaking and pregermination method for hybrid rice

Abstract

The invention discloses a selenium-rich seed-soaking and pregermination method for hybrid rice. The method comprises the following steps: (1) firstly, thinly spreading hybrid rice seeds on a drying pad or cement ground, drying for 1-2 days, frequently stirring so as to enable the drying degrees of the seeds to be consistent; (2) packing the dried seeds into a nylon mesh bag in which the weight of the seeds does not exceed 10kg, and soaking the seeds in a selenium-rich water solution, blasting fresh air into the selenium-rich water solution by virtue of a blast blower when soaking the seeds, soaking the seeds for 10-12 hours in the day, fishing out from water and putting the seeds at home, draining, ventilating and helping the seed carry out aerobic respiration; (3) soaking the seeds in the next day for 5-7 hours, putting the soaked seeds into warm water at 38-42 DEG C, soaking the seeds for 10 minutes, taking out, draining, and carrying out insulating pregermination, and inspecting once every four hours; (4) successfully pregermination after 2-3 days; and (5) after pregermination of sprouts, thinly spreading the seeds on the ground in a room, refining the sprouts, sowing in the sun, wherein the total selenium amount of the rice sprouts is 18.4-180 microg / plant in transplantion.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a selenium-enriched seed soaking and germination accelerating method for hybrid rice. Background technique [0002] Rice is the main food crop in my country, and the population whose staple food is rice accounts for about 50% of the total population. my country's rice planting area reaches 29.96 million hectares, with a vast distribution area. Due to historical reasons such as food pressure, my country's rice production used to aim at high yield, and paid less attention to the content of rice microelements. With the increasing living standards of residents and the development of foreign trade, the development of microelement-enriched rice technology will continue to grow. received more attention. [0003] Selenium, the element symbol Se, is an essential trace element for the human body and is the active center of glutathione peroxidase. It has biological properties such a...
