The pillar industry. The township Wang Pingcun Nie Jiaxun planted 6,667 square meters of Dahongpao pepper in the barren gully, and in 1999, it earned more than 20,000 yuan. The cultivation techniques are as follows. The nursery shall collect ripe and full-grained fruit from the mature and fruitful middle-aged trees after the summer heat, take out the seeds after harvest and avoid exposure, so as not to affect the emergence rate. Both autumn and spring can be planted, but autumn is preferred. Autumn soil moisture is good, the emergence rate is high and neat, and the seeds do not need to be stored. The specific time is appropriate from October to November. Dahongpao Zanthoxylum seed shells are hard and have a lot of oil and must be degreased prior to sowing. Seed weight 1% of detergent powder soaked in water for 2d, remove and rub repeatedly, mixed with plant ash can be seeded. Dahongpao Zanthoxylum seedlings top soil ability is weak, avoid deep sowing, covering the thickness of 2-3cm. After sowing must be covered with organic fertilizer or wheat bran 2-3cm, is conducive to conservation, prevent compaction, improve the emergence rate. 2 Planting Dahongpao and Zanthoxylum Garden should be built on the sunny slope or semi-sunny slope in the middle and lower part of the hillside. Avoid mountain top tuyere. The plant spacing of the pepper plants is generally 3m4m. The row spacing of pepper trees should be adjusted according to local conditions, generally 2.5m3.5-4m; the plant spacing of prickly ash trees on terraces is generally 3-3.5m. It can be planted in spring and autumn. The spring planting should be late. It should be carried out when the sprouts of the pepper sprouts are about to sprout or start to sprout; autumn planting is carried out from late autumn to early winter; planting in the rainy season should be carried out immediately after the rain. Spring and autumn planting, after planting must be poured good water, autumn planting soil should also be piled against cold. In the rainy season, grab the earthworms, plant seedlings to beat the mud, and plant them with the Guo's method (opening joints, seedlings against the wall, and pedaling). The general survival rate can reach 95% or more. Soil fertilizer management and fertilization should be as early as possible, and two should be full. The fruit should be fertilized immediately after picking, mainly organic fertilizer, mixed n, p fertilizer once enough. Saplings apply 5–10 kg of fertilizer per farm, 0.5–0.15 kg of urea, 0.1–0.2 kg of p-fertilizers, and 6–7-year-old trees, each with 15–20 kg of applied fertilizer, 0.5 kg of urea, and 1–2 kg of p-fertilizer. Flowering and fruit enlargement should be applied as appropriate to increase fruit setting and promote fruit growth. Pouring water over the winter, sprouting, fruit growth period three times. Watering with fertilizers should be used in order to give full play to fertilizer efficiency and promote plant growth and development. After the beginning of July, fertilization and watering should be stopped to avoid secondary growth, affecting fruit development and wintering branches. In the growing season, we must timely cultivating and weeding, one can break the compaction, preserve the water, and the second can avoid weeding with the prickly ash tree to compete for water. Trim and dry 50-60cm, not too low or too high, too low for inconvenient management, high is not conducive to tree growth and canopy expansion. The shaping is based on a naturally happy shape. Generally, 5-7 main branches are reserved, and two to four lateral branches are selected for each main branch. Results The tree was pruned with sparseness, sparsely pests, crosses, overlapping, densely planted, and leggy branches, strong and weak, staggered and empty, so that the canopy was evenly distributed inside and outside the canopy, with air and light transmission, and three-dimensional results.
