Apricot tree soil testing and formulated fertilization method

Abstract

The invention discloses an apricot tree soil testing and formulated fertilization method, which comprises the steps of: 1) soil nutrient detection: optionally choosing 667 square meters of fruit trees in an orchard, selecting several fruit trees in S shape from the 667 square meters of fruit trees to serve as sample trees, evenly setting several sampling points at any sample tree's crown drip line along the circumference, conducting soil sampling in two layers along the soil depth at any sampling point, mixing the soil samples taken from a same layer of the sample trees, then reserving the sample by a quartation method, and detecting the content of elements in soil to obtain a test value; 2) calculating the fertilizer preparation amount; and 3) conducting fertilization: according to the calculation result of step 3), performing fertilization in three times after fertilizer preparation. Compared with the traditional fertilization method, the method provided by the invention is more accurate and reliable, is simple and practicable, improves the utilization rate of the fertilizer, saves fertilizer, increases soil fertility, improves fruit quality, and reduces the soil pollution caused by improper fertilization.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular, the invention relates to a soil testing formula fertilization method for apricot trees. Background technique [0002] At present, in my country's agricultural fertilization, especially the fertilization of apricot trees, the phenomenon of heavy inorganic and light organic fertilizers is common, and chemical fertilizers account for more than half. However, most farmers do not understand the soil nutrient status and the law of apricot trees' fertilizer requirements. They follow the customary fertilization mode and fertilize excessively. Improper methods lead to soil nutrient loss and imbalance, and long-term large-scale application of chemical fertilizers has brought many difficult problems to people, such as aggravation of physiological diseases, annual fruit size, and decline in fruit quality. Contents of the invention [0003] The object of the present invention is...
