Organic rice cultivation and weeding techniques

Organic rice There are more weeds in paddy fields. Because we cannot spray pesticides, we have adopted the principle of “in addition to early, small, and in addition to” and combined the agricultural control and biological control, and adopted manual extraction and the following methods.

1 before weeding herbicide grass. In the 40 to 50 days before transplanting, continuous irrigation of paddy fields was started to keep the soil in the field moist, so as to induce the growth of weeds, and the number of weeds was reduced by several plowing operations to achieve the purpose of herbicide; 10 to 15 days before transplanting, the method of manual extraction is used to remove the weeds left over from plowing, especially for vicious weeds such as the double-backed finches and senior weeds during rice growth. .

2 After planting seedlings, seedlings are pressed with grass and water pressure is applied during the growth period. Through rational planting, increasing the number of basic seedlings and scientific water slurry management of seedlings, etc., in order to achieve the purpose of inhibiting the growth of weeds.

3 three-dimensional planting, duck weeding. Using the method of three-dimensional planting, rice and duck symbiosis measures are used to control the occurrence of weeds in the field. The specific approach is to select a duck species that is moderate in size and strong in its ability to move and cultivate rice in synchronization with the planting of the rice to suppress the growth of weeds in the paddy field through duck activities. In general, 10 to 15 ducks per acre are more suitable.
