[0002] At present, in my country's agricultural production, especially the fertilization of chestnut 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 state of soil cents and the law of fertilizer needs of chestnut trees, and follow the customary fertilization mode , Excessive fertilization and improper methods lead to soil nutrient loss, imbalance, non-point source pollution, and soil acidification. Decreased fruit quality, groundwater pollution, etc.

Embodiment
[0022] 1. Soil nutrient detection: select a typical chestnut forest with an area of 1.5-10 mu, and make records on the map and survey sheet. When sampling, take two symmetrical points along the drip line of the tree crown, and the sampling depth is 40 cm. Select 10-12 trees in a serpentine direction, mix the soil samples at all sampling points evenly, take about 1 kg of samples according to the quartering method, seal them in plastic bags, and fill in the survey form; dry the soil samples and perform pretreatment , enter the soil sample for detection, use alkali solution diffusion method to measure available nitrogen, use sodium bicarbonate to extract molybdenum antimony anti-colorimetric method to determine available phosphorus, use ammonium acetate to extract flame photometer method to measure available potassium, get three test values, and make good record;

Abstract
The invention provides a method of formula fertilization of Chinese chestnut after soil testing. The method comprises the following three steps: detection of soil nutrients; calculation of formula fertilization amount; and fertilization. According to the invention, scientific and reasonable fertilization according to local conditions is realized, so soil nutrient loss and imbalance and non-point source pollution are prevented; proper fertilization is carried out, so Chinese chestnut has improved quality and does not suffer from physiological diseases; and the method is especially applicable to fertilization in a Chinese chestnut forest land.
Description
Technical field [0001] The present invention disclose a method of fertilizing soil measurement, especially a chestnut meter fertilization method. Background technique [0002] At present, my country's agricultural production, especially the fertilization of chestnut trees, is universal, and the phenomenon of inorganic light and organic is common. Chemical fertilizer accounts for more than 80-90%. Most farmers do not understand the status of soil beauty and the laws of chestnut trees. , Excessive fertilization, improper methods, causing soil nutrient loss, imbalance, facial source pollution, and soil acidification to become more and more serious; long -term application of chemical fertilizer has brought many difficult problems to agricultural production, exacerbation of physiological diseases, large and small results, results, and results of the year, result, results, and results of the year, result, results, and results of the year, and the results of the year, and the results of...
