The Method of Improving the Germination Rate of Rice Seeds Stored for Many Years

Abstract

The invention discloses a method for increasing the germination rate of rice seeds stored for years. The method comprises the following steps: (1) firstly drying the rice seeds in the sunshine for 1-2 days; (2) putting the dried rice seeds into a nylon mesh bag, putting the nylon mesh bag with the rice seeds into flowing clean water for soaking, soaking for 10-12 hours at the daytime, then fishing out the nylon mesh bag with the rice seeds from the water, putting back to the home, then draining, and ventilating; (3) soaking for 5-7 hours next day, putting the nylon mesh bag with the rice seeds into warm water with the temperature being 38-42 DEG C, soaking for 10 minutes, taking out, draining, and carrying out warm-keeping germination acceleration, wherein germination is completed after 2-3 days; (4) after germination is carried out on germinated rice seeds, spreading the seeds on indoor ground, carrying out bud refining, then putting into a seedling raising disc, putting nutrient soil into the seedling raising disc, uniformly sowing the germinated rice seeds and then covering with a layer of nutrient soil; (5) after the seedling disc is well arranged, stacking neatly; after vertical needles of the germinated rice seeds grow out of the soil by 1cm after 2 days, transferring to a seedling bed leveled in advance; and after 15-17 days, transplanting the seedlings to a big field; and (5) carrying out transplanting and fertilizer-applying management according to the conventional method till the rice is harvested.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for increasing the germination rate of rice seeds stored for many years. Background technique [0002] Since the 1980s, rice dry-raised sparse planting cultivation technology has been widely used in my country through introduction, experimentation and demonstration. With the great leap forward, rice production has developed rapidly, presenting a gratifying situation today, with large planting area, high per unit yield level, the total output ranks first in grain output, and remarkable economic benefits. [0003] The essence of rice dry seedling sparse planting transplanting technology is: use fertile and loose dry field soil, in the dry environment of the seedbed, to cultivate the root system, use loose and fertile topsoil of dry field plow layer, decomposed farmyard manure and peat are very difficult. There are few livestock and poultry breeding, and the low-lying...

[0003] The essence of rice dry seedling sparse planting transplanting technology is: use fertile and loose dry field soil, in the dry environment of the seedbed, to cultivate the root system, use loose and fertile topsoil of dry field plow layer, decomposed farmyard manure and peat are very difficult. There are few livestock and poultry breeding, and the low-lying floodplains, meadows, and grass ponds where peat can be dug have developed into paddy fields, with water source puffed particles, fine sand or perlite and other mineral materials as fillers, combined with inorganic fertilizer nutrients , practical application, agronomic practical effect is not ideal
