[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;
