Problems solved by technology

[0002] At present, in my country's agricultural fertilization, especially the fertilization of apple trees, the phenomenon of heavy inorganic and light organic fertilizers is common, and chemical fertilizers account for more than 80-90%. However, most farmers do not understand the soil nutrient status and the law of apple tree fertilizer requirements, and follow the customary fertilization mode. Excessive fertilization and improper methods cause soil nutrient loss, imbalance, non-point source pollution, and soil acidification are getting worse; long-term large-scale application of chemical fertilizers has brought many difficult problems to people, such as: aggravation of physiological diseases, annual results, Decreased fruit quality, groundwater pollution, etc.

Embodiment 1

[0019] 1. Soil nutrient detection:

[0020] 1) Sampling: Choose a typical orchard with a plot area of ​​1.5-10 acres, and make a record on the map sheet and survey sheet. When sampling, take two points along the outer edge of the crown of the fruit tree. Select 10-15 trees in a serpentine arrangement with a sampling depth of 0-40 cm. After the soil samples at all sampling points are mixed, take a sample of about 1 kg according to the quarter method and fill in the questionnaire to ensure that the sampling location is consistent with the fertilization location;

[0021] 2) Testing: Dry the soil sample, carry out pre-treatment, and enter the test to detect soil pH, organic matter, available nitrogen, available phosphorus, available potassium, and medium and trace elements; the pH of the soil is determined by the acidity method, and the determination of organic matter by dichromic acid Potassium method, the quick-acting nitrogen is determined by the alkaline diffusion method, the eff...

Abstract

The invention relates to an apple soil testing prescription fertilization method which is realized through three steps, namely soil nutrient testing, mixed fertilizing rate and fertilization, achieves scientific and reasonable fertilization, takes actions that suit local circumstances, does not lead to the nutrient loss, unbalance, non-point pollution and acidification of the soil, appropriately fertilizes, improves the fruit quality, has no pollution and physiological diseases, and in particular applicable in apple land fertilization.

Description

Technical field: [0001] The present invention designs a soil testing formula fertilization method, in particular an apple soil testing formula fertilization method. Background technique: [0002] At present, China’s agricultural fertilization, especially the fertilization of apple trees, emphasizes inorganic rather than organic, and chemical fertilizers account for more than 80-90%. Most farmers do not understand the status of soil nutrients and the law of fertilizer requirements for apple trees, and they follow the habitual fertilization mode. Excessive fertilization and improper methods have caused soil nutrient loss, imbalance, non-point source pollution, and soil acidification. Long-term large-scale application of chemical fertilizers has caused many difficult problems for people, such as: increased physiological diseases, large and small results, Decreased fruit quality, groundwater pollution, etc. Summary of the invention: [0003] The purpose of the present invention is t...
