Embodiment Construction

[0034] The present invention is implemented in Zhengwang Town and Bahu Town, Hedong District, Linyi City, Shandong Province.

[0035] The implementation site is multi-year rice-wheat rotation, the soil fertility is medium, the annual precipitation is about 700mm, the annual average temperature is 13℃, and the frost-free period is about 200d. Generally sow in early and mid-May, transplant in mid-to-late June, and mature around October 10.

[0036] Seedling technology

[0037] 1) Variety selection: choose early-growing varieties with fast rooting and strong growth, because the strong reduction reaction will inhibit the early growth of rice. High-quality rice varieties such as Koshihikari, Jingyin 119, and Zhongbu 67 can be used in the Linyi rice area.

[0038] 2) Selection of seedling field: It is best to choose vegetable garden or dry field for seedling field, and generally do not choose rice field. It is required to facilitate drainage and irrigation, loose and fertile soil...

Abstract

The invention provides a double functional layer type weeding method used in an organic rice field. The method is used for field weeding by creating double functional layers by means of the ecology principle according to the paddy field weed generating rule and ecology principle based on the condition of organic rice cultivation. According to the method, an organic reduction layer and a poplar leaf covering layer are created on the earth surface, and the harm caused by weed generation in the rice field can be effectively controlled by means of different functions of the organic reduction layer and the poplar leaf covering layer. Compared with existing organic rice field weeding methods, the weeding method has the advantages of being good in weeding effect, capable of improving the fertility of soil, reducing cost and improving efficiency, ecological, environmentally friendly, easy and convenient to implement and the like.

Description

technical field [0001] The invention relates to a method for weeding with a double-functional layer of an organic rice field. technical background [0002] China is a big country of rice production and consumption, and more than 60% of the population takes rice as the staple food. Therefore, the quality and safety of rice products have always been the focus of attention. At the end of the 20th century, in order to meet the market's demand for high-quality and safe rice, organic rice production developed rapidly in China and gradually became a new industry. Organic rice refers to the organisms and their products that do not use chemically synthesized fertilizers, pesticides, growth regulators, etc., nor use genetically modified technology in the production process, but follow the laws of nature and ecological principles, using the combination of planting and breeding, Rice grown by a series of sustainable agricultural techniques such as recycling. Weeds in rice fields are p...
