Packaging waste. Field pesticide or fertilizer packaging waste or white garbage should be collected, sorted and handled by dedicated personnel. Check the planting site and other ecological synergies. The orchard is developed in the way of "wearing a hat on the mountain, planting fruits on the mountainside, and wearing boots at the foot of the mountain" ("wearing a hat on the mountain": retaining the water conservation forest on the upper part of the hillside, "wearing boots at the foot of the mountain": setting up a water and soil barrier forest at the foot of the mountain). The infrastructure should be integrated with the landscape and water gardening to maintain biodiversity and reshape or restore the biological habitat. Check the orchard planning map and visit the orchard on site. Orchard planning During the existence of the orchard, scientific planning should be used to give full play to the ecosystem regulation service functions (soil restoration, soil and water conservation, wind and sand control, flood regulation, climate regulation), as well as cultural service functions such as landscape tours and nature education. Check the records of picking experience and tourism in the orchard.
