Problems solved by technology

[0005] Therefore, at present, the rice we plant is mainly hybrid rice, supplemented by ordinary rice. A large amount of pesticides and chemical fertilizers are used in the planting process. Although the yield is high, it will take time to eliminate the impact of taste, nutrients and chemicals on humans. research

Embodiment Construction

[0023] The present invention will now be described in further detail with reference to preferred embodiments.

[0024] Rice is an annual grass plant, about 1 meter high, with long and flat leaves, and panicles composed of many spikelets. Rice likes high temperature, high humidity, and short sunshine, and has no strict requirements on soil, and paddy soil is the best. The minimum temperature for seedling germination is 10-12°C, and the optimum temperature is 28-32°C. At the tillering stage, the daily average temperature is above 20°C, and the optimum temperature for panicle differentiation is about 30°C; the low temperature prolongs the differentiation of branches and spikelets. The optimum temperature for heading is 25-35°C. The optimum temperature for flowering is about 30°C, if it is lower than 20°C or higher than 40°C, fertilization will be seriously affected. Relative humidity 50-90% is appropriate. The period from panicle differentiation to full grain filling is the c...

Abstract

The invention relates to a natural farming method for planting rice. The natural farming method for planting rice includes the steps of a, rice variety selection; b, seedling raising; c, paddy field finishing; e, transplanting; f, irrigation and drainage management; g, usual paddy field management; and h, harvesting. The natural farming method for planting rice uses no external fertilizers including organic fertilizers and the like or pesticides, requires no weeding and uses continues cropping and reserved seeds. Soil, water and air quality needs to meet above national standard type-II, and surroundings are independent relatively. The natural farming method for planting rice increases income of farmers, lowers investment of farmers, protects water source areas and maintain environment and is of positive significance. As investment is low, price of rice is low. The naturally grown rice is especially rich in natural trace elements and meets native needs of human bodies.

Description

technical field [0001] The invention relates to a method for planting rice, in particular to a method for planting rice by natural farming. Background technique [0002] Rice is the most important food crop for human beings to survive. With the advancement of human cultivation and farming technology, this ancient crop is constantly glowing with new vitality, feeding more than half of the earth's population. At present, the world's rice planting area is about 152 million hectares, with an annual rice output of 586 million tons, and Asia's rice production accounts for 90% of the world's total. In the long run, the progress and innovation of rice technology will have an important impact on the survival and life of people in the 21st century. [0003] China is the world's largest rice producer and consumer. In 2001, the rice planting area was 28.6 million hectares, accounting for 1 / 5 of the world's rice cultivation area; the annual rice production was 185 million tons, accoun...
