Method for fertilizing soil in citrus orchard by using pig manure organic fertilizer

Abstract

The invention belongs to the technical field of citrus orchard soil fertilization. According to the method for fertilizing the soil of the citrus orchard by using the pig manure organic fertilizer, all the pig manure organic fertilizer is applied as a base fertilizer, the pig manure organic fertilizer is uniformly applied in an annular furrow with the depth of 20-30 cm, the fertilizing position is in an annular belt with the inner diameter 30-50 cm away from a trunk under a citrus crown and the outer diameter at a dripping position of the citrus crown, and soil is covered in time after the fertilizing. According to the application, a fertilization mode of partially replacing a chemical fertilizer with the pig manure organic fertilizer is adopted, so that the soil fertility and microbial diversity of the ponkan orchard are improved, the contents of total nitrogen, available phosphorus, rapidly available potassium and organic matters in the soil are comprehensively increased, the fruit yield is increased, and the fruit quality is improved.

Description

technical field [0001] The invention belongs to the technical field of citrus orchard soil fertilization, in particular to a method for fertilizing citrus orchard soil by utilizing pig manure organic fertilizer. Background technique [0002] Citrus fruit is rich in nutrients and excellent in color, aroma and taste. It is widely planted in my country and is an important source of economic income for farmers in my country. [1] . In recent years, as the planting structure of citrus orchards tends to be intensified and the cultivation density tends to be densely planted, the input of nitrogen and phosphorus chemical fertilizers in some planting areas has become higher and higher, resulting in generally low fertilizer utilization rates and imbalanced soil properties, which seriously affects the normal growth of crops. and its quality improvement [2-4] . At the same time, the nutrient loss caused by the excessive and unreasonable application of quick-acting fertilizers also bri...

AI Technical Summary

Problems solved by technology

In recent years, as the planting structure of citrus orchards tends to be intensive and the planting density tends to be densely planted, the input of nitrogen and phosphorus chemical fertilizers in some planting areas is getting higher and higher, resulting in generally low fertilizer use efficiency and imbalanced soil properties, seriously affecting the normal growth of crops and its quality improvement [2-4]

At the same time, the nutrient loss caused by excessive and unreasonable application of quick-acting fertilizers also brings pollution problems such as the deterioration of the water body environment [5,6]

According to the announcement of the Ministry of Agriculture, the utilization rate of nitrogen fertilizer in my country is about 30% at present. Excessive and unreasonable fertilization leads to problems such as nutrient loss in orchards, soil compaction, salinization, and groundwater nitrate exceeding the standard, and the stress resistance of trees is reduced, and physiological diseases are aggravated. Problems such as reduced fruit storability and low quality directly affect the economic benefits of citrus planting and become an important obstacle restricting the benign development of citrus industrialization [5-8]
