Problems solved by technology

[0002] At present, in my country's agricultural fertilization, especially the fertilization of large cherries, most farmers do not understand the soil nutrient status and the law of fertilizer demand of large cherries, and follow the customary fertilization mode, excessive fertilization, and improper methods, resulting in soil nutrient loss, imbalance, non-point source pollution, Soil acidification is becoming more and more serious, and the pH of some fields planted with large cherries all year round has dropped by 1.2 units; the long-term application of large amounts of chemical fertilizers has brought many difficult problems to people, such as: a 9.7% decrease in yield, aggravation of physiological diseases, size Annual results, fruit quality decline, groundwater pollution, etc.

Embodiment 1

[0020] 1. Soil nutrient testing:

[0021] 1) Sampling: 10-12 trees are selected in a checkerboard arrangement in a cherry orchard, avoiding the edge of the field, and two points are taken along the outer edge of the crown of the fruit tree, each 30-50 cm in circumference, and the sampling depth is 0-30 cm. After mixing the soil samples at the sampling point, take about 1 kg of samples according to the quartering method;

[0022] 2) Detection: Dry the soil sample, remove the stones and pass through a 2 mm sieve, enter the test, detect soil pH, organic matter, available nitrogen, available phosphorus, and available potassium; soil pH is measured using a pH meter method, and organic matter is measured using dichromic acid Potassium method, available nitrogen is determined by alkaline solution diffusion method, available phosphorus is determined by sodium bicarbonate extraction molybdenum antimony anti-colorimetric method, available potassium is determined by acetic acid extractio...

Abstract

An outdoor large-cherry soil test fertilizer application method comprises a step of soil nutrient detection, a step of fertilizer preparation amount calculation, and a step of fertilizer application, so the method reaches scientific and reasonable fertilizer application, and realizes the adjustment of measures according to local conditions, thereby the method has the advantages of no soil nutrient loss, imbalance, surface source pollution or soil acidification, proper fertilizer application, fruit quality improvement, no pollution, and no physiological diseases, and is especially suitable for the large-cherry fertilizer application.
