Pollination Tree Configuration Pollination trees were planted between rows or between plants, and the ratio of the main cultivars to the pollination cultivars was (4-7):1. Planting method The planting pit has a diameter of 80 cm and a depth of 80 cm, straw is applied at the bottom of the pit, and the thickness is 20 cm. The top soil is filled with a thickness of 30 cm, and the farm fertilizer is applied to 20 kg, and the superphosphate is 1.5 kg. Finally, the backfill is pitted. level. The orchards with a thickness of 80 cm or less in the mountains and soil layers need to be grooved along the planting line, with a depth of 100 cm and a width of 100 cm. The straw is applied at the bottom of the straw and has a thickness of 20 cm. It is filled with topsoil and has a thickness of 30 cm. The straw is applied with a thickness of 10 cm. Then it is filled with topsoil and the thickness is 10 cm. It is applied to a farmyard fertilizer of 20 kg and a superphosphate of 1.5 kg. , Finally backfill the topsoil to fill it. After the backfill, the water is irrigated and the pits are planted.
