Pregermination method of rice seeds

Abstract

The invention provides a pregermination method of rice seeds. The pregermination method includes: 1), seed drying, namely selecting the rice seeds good and full in quality, evenly spreading the rice seeds on concrete ground or a cushion and loading the rice seeds in a gunny bag after drying for 1-2 days; 2), seed soaking, namely soaking the seeds in clean water for 5-8 hours and then putting the seeds into a seed dressing agent for soaking for 30-40 minutes; 3), disinfection, namely adding 10kg of warm water to 8g of strong chlorine for mixing 3.5kg of the soaked rice seeds in proportion, performing disinfection for 3-5 hours and then fishing out the seeds to be cleaned in clean water and dried; 4), pregermination, namely filtering the rice seeds, evenly spreading the rice seeds on the bag, sealing the periphery of the bag with straws, controlling temperature to be from 38-42DEG C, and allowing the rice seeds to sprout after around 20 hours, wherein pregermination can be completed after 2-3 days. With the method, use of pesticides is reduced, labor force is saved, cost in pregermination is reduced, survival rate of rice is increased, disease resistance and insect resistance of the rice are enhanced, economic benefit is increased, and high promotion value is achieved.

Description

technical field [0001] The invention relates to the field of seed germination acceleration, in particular to a method for accelerating germination of rice seeds. Background technique [0002] Pregermination is a measure that can cause bud growth, dormant bud development and seed germination, or promote these pre-occurrence measures, which are all called pregermination. Pregermination can ensure that after the seeds have absorbed enough water, the nutrients in the seeds will be quickly decomposed and operated to supply the young embryos for growth. In agriculture, it usually refers to soaking in warm water, chemical treatment and other methods to make seeds, potato pieces, etc. germinate in advance. [0003] Rice is native to China, and rice was planted in the Yangtze River Basin of China 7,000 years ago. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Rice l...

Problems solved by technology

[0004] At present, there are many methods for most rice germination, mainly including steam germination, germination machine germination, kang germination, water limit germination, large pile germination, plastic germination and water immersion germination, etc. Steam germination requires equipment and fuel, and the key technology is difficult Grasp, should not popularize

Plastic shed germination, combining large piles of germination with plastic greenhouse technology, relying on natural heating, the seeds are heated evenly, but it needs long-term care and combination, while soaking in water is easy to use, the germination speed is fast, and the germination effect is good, but it is very prone to high temperature In the process of burning buds and accelerating germination, when the seeds are soaked, the final liquid medicine is not cleaned thoroughly, and the liquid medicine remains on the rice seeds, so it is not suitable for popularization.
