Organic planting (i.e. organic cultivation) is an agricultural production system that does not use chemically synthesized fertilizers, pesticides and growth regulators, nor does it use genetic engineering and ion radiation technology, but follows the laws of nature and adopts farming, physical and biological methods to fertilize the soil and control pests and diseases, so as to obtain safe organisms and their products. Its core is to establish and restore the biodiversity and virtuous circle of agricultural ecosystem in order to maintain the sustainable development of agriculture.

Cheng was praised by academic circles as a senior engineer in the field of biological intensification "Yuan Longping". He put forward the direction of combining biological intensification with green organic cultivation in a forward-looking way, conducted arduous research for 30 years, and made the greatest contribution to human society. The perfect combination of the two forms a great research achievement: biological enhanced organic cultivation technology, which not only ensures the content of trace elements in crops, but also ensures the complete natural green growth of crops.

In practice, the advantages of bio-enhanced organic cultivation technology are mainly manifested in the following links:

1, seed selection. In view of the lack of trace elements such as chromium, selenium, zinc, magnesium and lithium, the characteristics of thousands of crop seeds were observed and carefully selected, and the varieties that were most easily absorbed by scarce trace elements were selected for cultivation.

2. Breeding. Through the continuous strengthening of traits, excellent seeds with better and more prominent traits were selected.

3. Soil improvement. According to the requirements of seed selection, strict soil improvement should be carried out: removing hardening, removing heavy metals, removing chemicals and rebuilding soil microbial ecological environment.

4. Water source transformation. Carefully select groundwater, remove heavy metals and chemical pollution, and achieve the state of pure mineral water. Carefully select irrigation technology is adopted during irrigation to avoid any pollution that may occur during irrigation.

5. Develop green organic nutrient solution. First, it overcomes the fertilizer complexing effect of inorganic mineral elements, and makes the mineral elements in nutrients become organic complexes, which is beneficial to the absorption and enrichment of crops. Selecting fertilizer carriers and microbial colonies can achieve the purpose of producing biological fertilizers.

6, biological pest control, according to the characteristics of crop growth process, formulate specific biological pest control technology, without using a drop of pesticide.
