Organic peony planting mode

Technical Field

the invention belongs to the technical field of planting modes, and particularly relates to an organic peony planting mode.

background

The organic agriculture development is promoted due to the surplus of agricultural products, the deterioration of ecological environment and the environment-friendly and meaningful movement in developed countries; the international organic products began in the 70 th 20 th century, marked by the establishment of the international organic agriculture movement alliance in 1972. In 1994, the national institute of environmental protection in China established the center for organic food in Nanjing, which marks that organic products have taken a substantial step in China.

the organic product is a pure natural, pollution-free, safe and nutritional food, also called as 'ecological food'. Research shows that the organic product contains more microelements such as iron, magnesium and calcium and vitamin C, and the content of heavy metal and carcinogenic nitrate is lower.
