(1) Putian and variety selection. The ponds and ponds of the species should be selected to have a water depth of no less than 1.3-1. 6 meters, with slow water flow, slow fluctuation, and deep and fertile silt layers. Varieties should be based on the important local conditions and cultivation requirements, choose a long period of growth, suitable for deep-water late-maturing varieties. (2) Soil preparation and fertilization: Deep-water pit ponds are difficult to cultivate because of the deep water level, and generally they are not suitable for site preparation. The new pit can be deep-turned when the water level is shallow for the year before planting, and organic fertilizer is applied. The quantity is better. In the spring of the following year, the mud-dug planting was conducted according to the planting distance. (3) Selective planting: The planting period is generally before and after the frost break, the planting edge is early, the water temperature is low, unfavorable to germination, and the seedlings are easy to be rot; the planting is late, the stems and shoots are longer, and are easily damaged. Before planting, dig out seedlings from the remaining fields and select the ones that meet the characteristics of this species and that are thick, tidy, and finely sectioned. In general, it should be planted in whole or large scales, and at least two complete sections. Select the species, size, grading, planting, so that the growing trend is neat and consistent. It is best to dig, on-demand, and plant. Planting density is a row spacing of 2. 5 materials, about 1.5 meters away from the hole, planting 3-4 branches per hole and 150-250 kg per acre. There should be about 3 meters around the pits and ponds, and all the gibbons should be headed to the pond so as not to go from the stem to the pond wall.
