Problems solved by technology

Improper control can easily lead to large areas of dead seedlings and destroyed seedlings, which not only wastes manpower and financial resources, but more importantly, delays farming time, affects the quality and progress of seedling raising, especially mechanical operations, reduces rice production, and is therefore extremely harmful
[0003] At this stage, rice seedlings have basically changed from the previous water seedlings to the current dry seedlings, and the disease of seedlings is still controlled by spraying with water, which is time-consuming and labor-intensive.

Embodiment 1

[0043] 1) Seed selection and drying

[0044] Take out the seeds, remove the shriveled seeds and impurities, and select plump, bright-colored seeds. 12 days before sowing, dry the seeds on a sunny day from 9:00 to 16:00 during the day, and spread the seeds evenly on the drying field with a thickness of 7 cm. , Turn it frequently during the day, pile it up and cover it at night, and let it dry for 3 consecutive days.

[0045] 2) Germination

[0046] Take 10kg of seeds, add clean water to the bucket and soak the seeds continuously for 2 days, add 25% prochloraz 2000 times the leaves to soak the seeds for 2 days, put them in a constant temperature incubator to accelerate germination for 1 day, and wait until the seeds are white.

[0047] 3) Preparation of bacterial-drug compound preparation

[0048] 3.1) Preparation of traditional Chinese medicine extract: Take 500 grams of honeysuckle, wash, dry, and crush, add 1.5 liters of petroleum ether to soak for 32 hours for extraction, ...

Abstract

The invention relates to a method for functional barrier factors preventing damping-off in a process of soilless rice seedling cultivation, and belongs to the technical field of rice planting. The method includes the following technological steps: 1) seed selection and seed sunning; 2) germination promotion; 3) preparation of a bacterial and drug compound preparation; 4) seed disinfection; 5) seedbed disinfection; 6) seeding; 7) water management; and 8) light and temperature management. The method for the functional barrier factors preventing damping-off in the process of soilless rice seedling cultivation is reasonable in design. Compared with traditional soil seedling cultivation, the method has good internal absorption and conductivity. When applied in seedling cultivation operation orseedling stage, the method can effectively prevent and control rice seedling damping-off and achieve the effects of saving time and labor.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a method for preventing dysfunctional factors of blight in the process of rice seedling raising without soil. Background technique [0002] At present, rice blight is a devastating disease that often occurs in rice seedlings. It is caused by soil-inhabiting bacteria such as Fusarium and Rhizoctonia, as well as adverse climate and environmental conditions (low temperature, salinity, etc.). Improper control can easily lead to large areas of dead seedlings and destroyed seedlings, which not only wastes manpower and financial resources, but more importantly, delays farming time, affects the quality and progress of seedling raising, especially mechanical operations, reduces rice production, and is therefore extremely harmful. [0003] At this stage, rice seedling raising has basically changed from the previous water seedling raising to the current dry seedling raisin...
