2. It is necessary to meet the conditions of ecological diversity, and there should be integrity, coordination and circular diversity. About half of the land in Long Ze Nong Yu Farm is used for growing food and vegetables, and the other half is used for breeding, forming an ecological zone. Formed an organic whole, the whole farm includes woodland, lawn, animal husbandry area, miscellaneous grains area and vegetable area. There are two fish ponds on the farm, next to the lawn area and small shrubs, which are very suitable for the natural ecological environment. Ecological farms attach great importance to ecological diversity, with an average of 1 cow, 4 pigs and more than 20 chickens and ducks per hectare of land. Long Ze Nong Yu's farm is about 16- 17 hectares. In addition to aquaculture, mules, donkeys, pigs, cattle and other domestic animals are also raised in proportion.
3. Environmental protection. Soil, water and air need to pass the test and reach the national standards GB5084-2005 and GB15618-2018. At the same time, the pollution sources near the farm are also strictly regulated. "If there are chemical plants or heavy pollution sources near 10 km and 20 km, it will definitely not work."
4. Records of various indicators. The chemical fertilizers and pesticides used in farms need to be traced back for three years to see if there are any prohibited things and whether they meet the conditions of ecological protection. The second is the breeding records, all the processes of agricultural products produced by the farm from seedling raising to final harvesting and planting, as well as what was used in the middle, how much was used, and whether it exceeded the standard. Every item should be traced back to the source, and the buyer should put it on record. Packaging also requires food-grade packaging materials. The third is the sales record. No matter what kind of high technology a farm uses, the output of agricultural products always has a certain amount. There are also technical records, such as planting information, which technologies were used in the planting process and so on.
