Embodiment 1

[0032] Embodiment 1, a kind of rice seed germination method, adopts the following steps:

[0033] 1. Seed soaking treatment of rice seeds:

[0034] Take 1 kg of non-infested, mature and plump rice seeds of indica type and japonica type rice, put them into different seed bags respectively, select non-polluting farmland irrigation water, soak the seeds for 60 hours at a temperature of 20°C, take them out, and then Wash it twice with farmland irrigation water, place it on a clean cement floor for 2 hours, and then use it;

[0035] 2. Pregermination of rice seeds:

[0036] Place the sterilized rice seeds together with the mesh seed bag in a constant temperature box with a temperature of 25°C and a humidity of 70-80% for germination, and stop the germination after the rice seeds are broken and exposed;

[0037] 3. Start the growth control of rice buds and valleys:

[0038] Pave the fresh rice buds with a thickness of 10 cm, place them in an environment with a temperature of 25°C...

Embodiment 2

[0048] Embodiment 2, a method for accelerating germination of rice seeds, adopt the following steps:

[0049] 1. Rice seed soaking:

[0050] Take 1 kg of indica and japonica rice seeds that are free from insect infestation, mature and plump, and put them into different mesh seed bags, select non-polluting farmland irrigation water, soak the seeds for 40 hours at a temperature of 35°C, and take them out. Then wash it 3 times with farmland irrigation water, place it on a clean cement floor for 2 hours, and set it aside for use;

[0051] 2. Pregermination of rice seeds:

[0052] Put the sterilized rice seeds together with the seed bag in an incubator with a temperature of 35°C and a humidity of 70-80% to accelerate germination. When the length of the root reaches 5-10 cm and the length of the bud reaches 1-3 cm, stop. Spare for germination;

[0053] 3. Start the growth control of rice buds and valleys:

[0054] Pave the fresh rice buds with a thickness of 5 cm, place them in ...

Abstract

The invention discloses a paddy rice seed pregermination method. When radical buds of paddy rice grow up to a specified standard, a physical method is used to control the growth of the radical buds, thereby widening the optimal period of seeding, so that the aims of labor conservation, cost conservation, effect enhancement and labor intensity relief are achieved. Compared with the traditional paddy rice pregermination seeding, the method can improve the seeding quality remarkably, and in particular to applying the method to mechanized direct seeding of paddy rice, the resistance of the machinery transmission of the seeds can be reduced obviously, so that the sprouts can pass through a seed passage smoothly and the seeding quality is guaranteed; when the paddy rice seed sprouts are prepared, the 'seed soaking-germination accelerating' process does not need to be repeated everyday; and the method has the characteristics of simplicity, convenience, easiness for mastering the technology and the like, and can be widely applied to paddy rice cultivation.

Description

technical field [0001] The invention relates to rice germination and sowing, in particular to an operation method for controlling the growth of rice buds and grains and root buds through physical means, thereby achieving the benefit of rice sowing. Background technique [0002] my country is the most populous country in the world and one of the major agricultural countries in the world. Rice is the most important food crop in my country. However, rice cultivation is mainly based on germination and sowing. With the transfer of human resources to the secondary and tertiary industries, the agricultural labor force is decreasing day by day, rice is gradually tending to large-scale production, and the popularity of agricultural mechanization is increasing. Transplanting rice seedlings and live broadcasting by machine. [0003] The mechanized sowing has always been the direct sowing of fresh buds, which has very strict requirements on the length of the root buds of the bud valle...
