Description

technical field

[0001] The invention relates to a rice seed soaking agent and a technology for preventing and controlling weedy rice in water-directed paddy fields. Background technique

[0002] The direct-seeding technology of cultivated rice is popular among farmers for its advantages of saving agricultural production costs, lower labor intensity, and early emergence of rice seedlings. In recent years, with the large-scale promotion of this light-type cultivation technology, the area of ​​direct-seeding rice in my country has exceeded 2 million hectares. In addition, with the development of marketization, the advancement of industrialization and urbanization, it will inevitably lead to changes in the structure of the rural labor force. Therefore, adopting water direct seeding is an important way of rice cultivation in my country in the future.

[0003] As a time-saving, labor-saving and cost-saving cultivation technology, direct-directed rice has continued to expand its p...
