Cultivation techniques of prickly ash seedlings

1. Soil preparation (1) method of land preparation. When building a garden on flat land, the whole garden can be prepared. Turn 30cm to 50cm deep, apply 4000kg / 5000kg base fertilizer to deep ploughing mu, flatten and rake fine. The method of banded soil preparation can also be used to dig a ditch with a width of 1 to 1.2 meters, separate the raw soil and mature soil, and then evenly fill the ditch with mixed soil fertilizer and soil to 20 cm from the ground, and dig a large pit of 1 square meter at the planting point. If you care about the construction of a garden on a gentle hillside, you can form a counter-slope terrace with a high outside and a low inside according to the contour line. The width of the terrace should be 1.5-2.5 meters or 2-3 meters, and the planting site can be dug into a large pit of 60 cm × 60 cm × 80 cm. (2) time of soil preparation. Prepare the soil 6 months or one year before planting pepper.

Second, cutting and planting (1) seedling standard. Seedlings with straight and sturdy stems, full Lignification of branches, developed roots, short and thick main roots, many lateral roots, full terminal buds, no diseases and insect pests and mechanical damage were selected. (2) planting density. The plant spacing and row spacing are 2 m × 3 m, 2 m × 4 m or 4 m × 5 m, with 50 plants per mu. (3) planting time. Planting can be divided into spring planting, autumn planting and winter planting. Spring planting can be carried out before the prickly ash tree sprouts. (4) planting method. Before planting, the seedlings should be soaked in water for 12 hours for 24 hours, so that the seedlings can fully absorb water and help to improve the survival rate. Zanthoxylum bungeanum seedlings are brittle and easy to break, which should be protected and the broken roots should be cut off. When planting, put the seedlings vertically into the dug planting pit, and then cultivate the soil, step on each layer of soil, and lift the seedlings slightly upward until the soil is level with the surface. Build a planting circle with a diameter of about 1 meter around the pepper seedlings, irrigate the planting water, seal the soil, and cover with plastic film to preserve soil moisture. The method of cutting off dry and sealing soil pile can be used for planting in winter.
