Embodiment 1

[0032] (1) Sun-drying: sun-dry the rice seeds for 2 days, and turn them frequently during the sun-drying, so that the dryness of the rice seeds is consistent, and select the seeds after the sun-dried rice seeds are cooled;

[0033] (2) Seed selection: select rice seeds with full grains and the same size;

[0034] (3) Seed soaking: Soak the rice seeds obtained in step (2): Soak the rice seeds for 48 hours at a water temperature of 30° C., then place the rice seeds on gauze with good air permeability and good draining effect, and then use the gauze Covering, moisturizing and heat preservation for germination;

[0035] (4) Simulated drought treatment: when the rice seeds soaked in the step (3) begin to break the chest or show white, spread the rice seeds flat on the clean ground, dry them under the condition of 40°C, and turn them over in good time. Exposure to the sun; when the water content of the rice seeds is lower than 14%, the rice seeds are stored for 50 days at a tempera...

Embodiment 2

[0040] (1) Sun-drying: sun-dry the rice seeds for 3 days, turn them frequently during the sun-drying, so that the dryness of the rice seeds is consistent, and select the seeds after the sun-dried rice seeds are cooled;

[0041] (2) Seed selection: select rice seeds with full grains and the same size;

[0042] (3) Seed soaking: Soak the rice seeds obtained in step (2): Soak the rice seeds for 60 hours at a water temperature of 28° C. Covering, moisturizing and heat preservation for germination;

[0043] (4) Simulated drought treatment: when the rice seeds after soaking in step (3) start to break the chest or show white, spread the rice seeds flat on the clean ground, dry them at 30°C, turn them over in good time, and do not Exposure to the sun; when the water content of the rice seeds is lower than 10%, the rice seeds are stored for 45 days under ventilated and ventilated conditions with a temperature of 12°C;

[0044] (5) Seed drying and seed soaking again: the rice seeds af...

Embodiment 3

[0048] (1) Sun-drying: sun-dry the rice seeds for 3 days, turn them frequently during the sun-drying, so that the dryness of the rice seeds is consistent, and select the seeds after the sun-dried rice seeds are cooled;

[0049] (2) Seed selection: select rice seeds with full grains and the same size;

[0050] (3) Seed soaking: Soak the rice seeds obtained in step (2): Soak the rice seeds for 72 hours at a water temperature of 25° C., then place the rice seeds on gauze with good air permeability and good draining effect, and then use the gauze Covering, moisturizing and heat preservation for germination;

[0051] (4) Simulated drought treatment: when the rice seeds after soaking in step (3) start to break the chest or show white, spread the rice seeds flat on the clean ground, dry them at 35°C, and turn them over in good time. Exposure to the sun; when the water content of the rice seeds is lower than 12%, the rice seeds are stored for 60 days under ventilated and ventilated c...

Abstract

The invention belongs to the technical field of agriculture cultivation and specifically relates to a method of processing rice seeds and rice shoots for improving the paddy rice resistance performances. By simulating drought and low temperature to respectively process rice seeds and rice shoots, the ability of rice plants to resist diseases and insects is increased; at the filling stage and the milk-ripe stage of the rice, leaf blast rate of the rice plants that are processed by simulating drought and low temperature is respectively reduced to 22.1 percent and 28.7 percent in comparison with the rice plants that not processed; and at the same time, at the filling stage and the milk-ripe stage of the rice, the number of brown planthopper of the rice plants that are processed by simulating drought and low temperature is respectively reduced to 19.4 percent and 24.1 percent in comparison with the rice plants that not processed. After the rice seeds are processed by simulating drought and low temperature, the ability of the rice to resistance leaf blast and planthopper is significantly strengthened while significantly increasing the rice production to 9.2 percent; and the use of pesticide during the production process of the rice is reduced, thus the rice is ensured to be produced with safety, high quality and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for treating rice seeds and seedlings to improve rice resistance. Background technique [0002] Rice (Oryza sativa) is an important food crop for humans, and about 50% of the world's population uses rice as a staple food. About 95% of the population in Asia takes rice as a staple food. In 2013, my country's rice accounted for 40% of food crops, ranking first. At the same time, my country is the world's largest rice producer and rice consumer. Therefore, reducing rice pests and diseases is of great significance to increasing rice yield and ensuring my country's food security. [0003] With the increase of rice planting area year by year, the problem of rice plant diseases and insect pests is becoming more and more serious, which has a serious impact on rice production and huge economic losses. In the process of rice production, rice pests and ...
