Embodiment 1

[0019] A rice seedling raising method for improving rice stress resistance, and the seedling raising method includes the following steps:

[0020] (1) Select high-quality rice seeds, after removing impurities, use a large-caliber container to fill ice water, evenly withdraw the rice seeds on the water surface to allow them to sink naturally, and immediately remove the husks floating on the water surface, and then let them sink. The full rice seeds in the water are soaked in ice water for 2 hours;

[0021] (2) After step (1), the rice seeds soaked in ice water are taken out and spread in a cool and ventilated place to remove the surface moisture of the rice seeds. The thickness of the rice seeds is 3mm, and the rice seeds are not overlapped as the degree, and the ambient temperature is 22 ℃, wind speed is 3m / s, cool for 6h;

[0022] (3) Plow the ground 30cm deep in the field, dry the surface soil to make the surface soil moisture content of 18%, and then apply the biogas slurry on th...

Embodiment 2

[0030] A rice seedling raising method for improving rice stress resistance, and the seedling raising method includes the following steps:

[0031] (1) Select high-quality rice seeds, after removing impurities, use a large-caliber container to fill ice water, evenly withdraw the rice seeds on the water surface to allow them to sink naturally, and immediately remove the husks floating on the water surface, and then let them sink. The full rice seeds in the water are soaked in ice water for 2.5 hours;

[0032] (2) After step (1), the rice seeds soaked in ice water are taken out and spread in a cool and ventilated place to remove the surface moisture of the rice seeds. The thickness of the rice seeds is 4mm. The rice seeds are not overlapped as the degree, and the ambient temperature is 25 ℃, wind speed of 5m / s, cool for 7h;

[0033] (3) Deeply plow the land 35cm in the field, dry the surface soil to make the surface soil moisture content of 20%, then apply the biogas slurry on the soil...

Embodiment 3

[0041] A rice seedling raising method for improving rice stress resistance, and the seedling raising method includes the following steps:

[0042] (1) Select high-quality rice seeds, after removing impurities, use a large-caliber container to fill ice water, evenly withdraw the rice seeds on the water surface to allow them to sink naturally, and immediately remove the husks floating on the water surface, and then let them sink. The full rice seeds in the water are soaked in ice water for 3 hours;

[0043] (2) After step (1), the rice seeds soaked in ice water are taken out and spread in a cool and ventilated place to remove the surface water of the rice seeds. The thickness of the rice seeds is 5mm, and the rice seeds are not overlapped as the degree, and the ambient temperature is 28 ℃, wind speed of 7m / s, cool for 8h;

[0044] (3) Deeply plow the land 40cm in the field, dry the surface soil to make the surface soil moisture content 22%, and then apply the biogas slurry on the soil...

Abstract

The invention discloses a rice seedling growing method for improving stress resistance in rice; the method comprises the steps of selecting high-quality rice seeds, removing impurity and flat seeds, exercising the seeds at low temperature, cooling the seeds, accelerating germination with nutrition, preparing a seedling substrate, sowing by broadcasting to grow seedlings, and managing growth; the method of the invention is simple and practical, is easy to implement, is lower in time and labor consumption than traditional methods in terms of work quantity, is up to 70% and above in germination acceleration rate, takes less time to perform sowing by broadcasting, is up to 95% and above in emergence rate, allows uniform emergence, enables the seedlings to grow robust and sound after management, the seedlings are exercised, the transplanted seedlings survive fast, have good resistance and high bolting rate, and transplanting consumes fewer seedlings.

Description

Technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a rice seedling raising method for improving rice stress resistance. Background technique [0002] Rice is native to tropical Asia and is an annual gramineous plant with 24 chromosomes. After being widely planted in China, it gradually spread all over the world. Rice grains are called rice or rice after they are hulled. Nearly half of the world's population feed on rice. There are many ways to eat rice, including rice, rice porridge, rice cakes, rice cakes, rice noodles and rice wine. In addition to being edible, rice can also be used to make starch, wine, and vinegar. Rice bran can be used to make sugar, squeeze oil, and extract furfural for industrial and medical purposes. Rice husks and rice stalks also have many uses. The main rice-producing areas in my country are mainly Northeast China, the Yangtze River Basin, and the Pearl River Basin. Rice likes high temper...
