Embodiment 1

[0029] A cultivation method of Guiyu No. 9 rice, comprising the following steps:

[0030] (1) Seed drying: Before sowing, lay the seeds in the sun to a thickness of 3 to 5 cm and dry them for 2 days. Turn them over 4 times a day to ensure that the seeds are evenly dried; the ground temperature should not exceed 50°C during drying;

[0031] (2) Seed selection and cleaning: adopt the method of salt water seed selection, dissolve an appropriate amount of salt in water, and adjust the density of brine to 1.14-1.16g / cm 3 , put the seeds into the salt water, remove the floating empty grains while stirring, fish out the full rice that sinks below, and then wash off the salt with clean water before soaking the seeds;

[0032] (3) Seed soaking and accelerating germination: Soak rice seeds with 50% thiram 500 times liquid by weight for 48 hours, remove them, wash with warm water at 45-50°C and raise the temperature, then dry them to accelerate germination. When 80% of the seeds grow 2.6...

Embodiment 2

[0043] A cultivation method of Guiyu No. 9 rice, comprising the following steps:

[0044] (1) Seed drying: Before sowing, lay the seeds in the sun to a thickness of 3 to 5 cm and dry them for 3 days, and turn them 6 times a day to ensure that the seeds are evenly dried; the ground temperature should not exceed 50°C during drying;

[0045] (2) Seed selection and cleaning: adopt the method of salt water seed selection, dissolve an appropriate amount of salt in water, and adjust the density of brine to 1.14-1.16g / cm 3 , put the seeds into the salt water, remove the floating empty grains while stirring, fish out the full rice that sinks below, and then wash off the salt with clean water before soaking the seeds;

[0046] (3) Seed soaking and germination acceleration: Soak the rice seeds with 50% thiram 600 times liquid by weight for 48 hours, remove them, wash them with warm water at 45-50°C and raise the temperature, then dry them to accelerate germination. When 80% of the seeds ...

Embodiment 3

[0057] A cultivation method of Guiyu No. 9 rice, comprising the following steps:

[0058] (1) Seed drying: Before sowing, lay the seeds in the sun to a thickness of 3 to 5 cm and dry them for 2 days, turning them 5 times a day to ensure that the seeds are evenly dried; the ground temperature should not exceed 50°C during drying;

[0059] (2) Seed selection and cleaning: adopt the method of salt water seed selection, dissolve an appropriate amount of salt in water, and adjust the density of brine to 1.14-1.16g / cm 3 , put the seeds into the salt water, remove the floating empty grains while stirring, fish out the full rice that sinks below, and then wash off the salt with clean water before soaking the seeds;

[0060] (3) Seed soaking and accelerating germination: Soak the rice seeds with 50% thiram 550 times liquid by weight for 48 hours, then remove them, wash them with warm water at 45-50°C and raise the temperature, then dry them to accelerate germination. When 80% of the se...

Abstract

The invention relates to the field of crop cultivation, in particular to a cultivation method of GY9 rice. The cultivation method comprises the steps of seed airing, seed selecting and cleaning, seed soaking and pregermination, seeding and seedling raising, rice field preparation, seedling transplanting, field management, pest and disease control and the like. The cultivation method of GY9 rice, provided by the invention, follows the growth cycle and the habits of rice, performs reasonable fertilization according to different growth periods of rice, and therefore, is high in fertilizer utilization ratio; the whole course from seed selecting and seedling culture to transplanting adopts regular cultivation, fertilization is reasonable, and pest and disease control is appropriate, so that the anti-disaster ability of rice is enhanced, the quality perfection and improvement effect is excellent, and the method is simple and low in cost; not only is the pest and disease incidence of rice lowered, but also the yield of rice is improved; and when the cultivation method provided by the invention is used for rice cultivation, the yield per mu can reach 650 kg, and the cultivated rice is full in particle, rich in nutrition and guaranteed in quality.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a cultivation method of Guiyu No. 9 rice. Background technique [0002] Rice, an annual grass plant, is an important food resource. People in many parts of the world rely on it as a staple food. Especially in my country, rice planting is one of the industries with a huge system in my country's planting industry. The most basic industry, rice feeds more than one billion people. The sown area of ​​rice in my country accounts for about 29% of all food crops, and about 60% of the population uses it as a staple food. However, at present, my country's population is growing rapidly and the area of ​​cultivated land continues to decrease. This also puts great pressure on the cultivation and supply of rice. We must cultivate higher-yield and high-quality rice crops within a certain area of ​​cultivated land. Moreover, with the development of science and technology and the improvement of pe...
