Embodiment Construction

[0016] Below in conjunction with embodiment the present invention is further described.

[0017] 1. In 2014, the company selected the organic rice base in Yingshui Village, Yulin Town, Ji'an City, Jilin Province (No. 100p1300572) certified by China Green China, and used 11.22 mu (1 mu = 666.7m 2 ) area to carry out the test, and release decomposed pig manure according to the standard of 3 cubic meters per mu. The rice varieties are Jiyang No. 11 and Akita Komachi excellent varieties.

[0018] 2. Use 1:1.3 salt water to select very plump seeds from seeds with a germination rate of more than 95%, and soak them in 1:50 quicklime water. Drought seedlings per square meter are pressed 0.1 jin of pregerminated seeds, and the transplanting density in the field is 30cm * 30cm (9 inches * 9 inches) square, and there are 2 seedlings in every hole.

[0019] 3. After transplanting on May 25, establish a water layer of about 2 inches to facilitate rice tillering. In the mid-term, the water...

Abstract

Provided is an organic cultivation method of northern paddy rice with the objective of harvesting 400 kilograms of northern organic paddy rice. The invention provides comprehensive management technology of rice. The comprehensive management technology comprises following steps: reasonable fertilization, seed selection, seed immersion, sparse-seeding and sparse-insertion, water layer management, manual and mechanical weeding, usage of 6% of kasugamycin and sex attractants, mixed aquaculture of river crabs, duckweeds, and rice fields; and the like. By adoption of the above mode, diseases, pests and weeds of an organic rice field can be effectively inhibited. The organic cultivation method of northern paddy rice is high in practicability and operability in order to compensate for defects of cultivation of the northern organic paddy rice.

Description

Technical field [0001] The invention relates to the field of rice planting, in particular to a green cultivation method of northern organic rice. technical background [0002] Organic rice refers to following the laws of nature and ecological principles, adopting a set of sustainable agricultural technologies, including not using pesticides, fertilizers, growth regulators and other substances containing chemical components, so as to achieve sustainable and stable development of agriculture. [0003] There is a fallow period of 6 months a year in northern my country, and the winter is very cold and long, which effectively curbs a variety of diseases, insects, and weeds in the rice fields. In addition, the farming history in the north is short and the soil is fertile. Therefore, the north has a unique advantage in organic rice cultivation. ecological advantages. [0004] Most of the rice planted in northern my country is japonica rice. Japonica rice has a good taste and taste....
