Method for suppressing growth advantage of accompanying plant of wild rice

Abstract

The invention discloses a method for suppressing the growth advantage of an accompanying plant of wild rice. The method includes: covering the accompanying plant in a wild rice community with a black thin film, pruning and flattening the covered accompanying plant; using ropes to binding up four corners of the black thin film, and then using bamboo sticks to fixing the four corners after binding; covering the accompanying plant with the back thin film for 5-7 days, and then removing the black thin film till an over-ground part of the accompanying plant withers up and an underground part of the accompanying plant has vitality. In this way, the growth advantage of the accompanying plant is suppressed, and the development advantage of the wild rice community is promoted; and the accompanying plant which has high competition advantage and obstructs the development of the wild rice is suppressed in March-May every year. The method can effectively suppress the growth advantage of the accompanying plant in the wild rice community, facilitates expanding of the wild rice, can enhance the development of the community, can change the conventional methods for suppressing the accompanying plant of the wild rice, and can be applied in a wild rice original habitat protection area.

Description

technical field [0001] The invention belongs to the technical field of wild rice protection, and in particular relates to a method for suppressing the growth advantage of associated plants of wild rice. Background technique [0002] Wild rice is widely distributed in my country. It starts from Sanya City, Hainan Province in the south, reaches Yunjiang County in Yunnan Province in the west, starts from Taoyuan County in Taiwan in the east, and reaches Dongxiang County in Jiangxi Province in the north. At present, a total of 3 species of wild rice have been found in 8 provinces, namely common wild rice. Oryza sativa, Oryza sativa and Oryza sativa. It has been determined that common wild rice (hereinafter referred to as wild rice) is the ancestor of cultivated rice, and has the closest parental relationship with rice. Wild rice has rich genetic diversity and excellent genes that cultivated rice does not have, which provides a solid material foundation for rice production and de...
