The invention discloses a method for efficient fertilization of zanthoxylum bungeanum. A fertilization formula adopted by the method disclosed by the invention is as follows: the ratio of N to P to K is 150 to 120 to 120, namely 5 to 4 to 4; 0.326.1kg of urea, 0.750kg of calcium superphosphate and 0.250kg of potassium chloride are applied to each plant, and are applied at mid-to-late of October and the middle ten days of May respectively; and a boron fertilizer is sprayed at the first ten days of May. With the adoption of the technical scheme disclosed by the invention, under a large-field testing condition, the yield of zanthoxylum bungeanum can be remarkably improved through accurate fertilization, can be improved by 43.5% at maximum and is averagely improved by 28.9%. According to 100 yuan per kilogram, the income of each Mu can be increased for 2176.1 yuan.
Description
technical field [0001] The invention belongs to the technical field of agriculture, and relates to a method for fertilizing prickly ash with high efficiency. Background technique [0002] Pepper (Zanthoxylumbungeanum) is an important spice tree species with high economic value. In 2015, the price of pepper in Shaanxi reached 100-120 yuan per kilogram. At present, pepper has become an ideal tree species for people in mountainous areas to get rid of poverty and become rich. However, due to extensive cultivation and management, many diseases and insect pests, and high mortality, after entering the blooming and fruiting period, the flower and fruit drop is serious, and the yield is low and unstable. The flower drop rate of Zanthoxylum bungeanum can reach about 70%, and the fruit drop rate is about 60%. Studies have shown that the main reason for ear drop and fruit drop is insufficient nutrient supply. For example, in Fengxian County, Shaanxi Province, the average pepper tree yi...
