In order to continue high-quality and high-yield peppercorns in the coming year, soil management and tree management should be done well after harvest.

First, deep-turning the soil with deep weeding can increase soil microbial activity, promote the decomposition and transformation of soil organic matter and minerals, increase soil fertility, and facilitate the growth and development of Zanthoxylum root. At the same time, weeds are removed through deep plowing, and pepper is most afraid of grass shortage. Therefore, there is a farmer saying that “prickling peppers do not weed and they are old.” Therefore, it is necessary to carry out deep turning after harvesting of Zanthoxylum bungeanum, preferably about one week after harvesting. At this time, the aboveground part grows slowly, and when it is turned right after the peak of the third peak of root growth, the wound will heal easily, and at the same time it will stimulate new roots. The growth. Deep puffing is best combined with the application of organic fertilizers to achieve improved soils, improved fertility, and promote robust tree growth. Deep plowing should pay attention to protecting the root system.

Second, increase the base fertilizer Zanthoxylum bungeanum through a year of growth, drawing tip, flowering, fruit growth, flower bud differentiation and other life activities, absorb large amounts of nutrients from the soil, resulting in lack of soil nutrients. Therefore, as long as timely fertilization, supplement soil nutrients, can reduce the supply and demand of soil nutrients conflict. The basal fertilizer is applied immediately after the fruit is harvested. It is at the third peak of the root system and has strong absorption capacity. The nutrients absorbed are mainly accumulation reserves, which can increase the nutrient level of the tree and is conducive to budding and flowering in the coming year. . The amount of fertilizer should be based on the age and size of the tree, generally 6-8 years of age, about 1 kilogram per tree, can be applied to each plant 10 kg of fully decomposed high-quality organic fertilizer and mixed with superphosphate 0.2-0.3 kg . The fertilization method mainly consists of alternating ring grooves and radiation grooves.

Third, to strengthen the soil most of the pepper planted on the slope, Taiwan, the easy loss of soil. Therefore, care must be taken to reduce soil runoff and water evaporation. Pepper is prone to frost damage, especially in stems and rhizomes. It is the earliest part of entering the dormancy period and ending dormancy. Cold resistance is poor. Therefore, it is necessary to strengthen soil cultivation and protect the roots and stems from wintering safely. Earthing is generally performed in late September.

Fourth, rational pruning and reasonable pruning is to regulate the tree's own growth in the results of the contradiction, to achieve the purpose of high yield each year.

1, pruning time: generally from the picking to the next year before germination can be, but after pruning to October before and when the soil thawing better.

2. Pruning method: The young trees are mainly sparsely cut, and sparse shear and short cuts are combined; the fruit trees are mainly short cuts and short cuts are combined with sparse shearing; the aging trees use short cuts for branch regeneration.

Fifth, to prevent and treat pests and diseases, one should remove dead branches, branches and leaves, and leaves after the harvest to reduce the source of pests and diseases; Second, timely prevention and control of Zanthoxylum bungeanum; third, use lime sulfur before the winter to dry, eliminate Branches of the cracks in the bacteria and eggs.
