Processing method of insect-resistant cotton seeds before sowing

Abstract

The invention discloses a processing method of insect-resistant cotton seeds before sowing. The method comprises the following steps: (1) collecting matured insect-resistant cotton seeds, drying the cotton seeds under the scorching sun in the sunny day for 2 to 3 days, then storing the cotton seeds in a warehouse, and controlling the temperature of the warehouse in a range of 9 to 12 DEG C and the relative humidity in a range of 65 to 70%; (2) taking out the insect-resistant cotton seeds one or two days before sowing, and filling 45 to 50 grams of cotton seeds into a gauze bag to produce seed bags; (3) soaking the seed bags into magnetized water for 6 to 8 hours, then taking out the seed bags to drain the water, then subjecting the seed bags to a softening and sterilization treatment, soaking the dried seed bags into a processing liquid for 12 to 18 hours, then washing the seed bags by clean water, drying in the sun, storing the seed bags in a warehouse for later use, and controlling the temperate of the warehouse in a range of 9 to 12 DEG C and the relative humidity in a range of 65 to 70%, wherein the storage time cannot exceed 48 hours. The provided method is simple, the actual operation is convenient, the provided processing liquid can kill the bacteria in a short time and can also soften the seeds, thus the seed germination will not influenced by the bacteria, and at the same time, the seed germination is promoted in a proper environment.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for treating insect-resistant cotton seeds before sowing. Background technique [0002] Insect-resistant cotton is currently divided into transgenic monovalent insect-resistant cotton and transgenic bivalent insect-resistant cotton. Transgenic monovalent insect-resistant cotton is a bacterial-derived Bt insecticidal protein gene that can specifically destroy the digestive tract of cotton bollworms. The digestive system of Lepidoptera pests leads to their death, but it is a kind of insect-resistant cotton that is harmless to humans and animals. [0003] During the expression process of the exogenous insect-resistant gene in the cotton plant of insect-resistant cotton, it has a great impact on the content and distribution of its own endogenous hormones, resulting in a decrease in the content and distribution of gibberellin in the growing point of insect-resistant co...

Problems solved by technology

[0004] The traditional method does not perform special treatment on the seeds before planting, resulting in insufficient germination rate of the seeds and increasing the cost of planting

Some growers have carried out germination treatment before sowing, but the germination agent is not properly selected, and the germination rate has not been significantly improved
