Fertilization method for improving citrus orchard soil and improving citrus quality

Abstract

The invention provides a fertilization method for improving citrus orchard soil and improving citrus quality. The fertilization method comprises the following steps: S1, applying a base fertilizer in a harvesting period of citruses; S2, applying a fertilizer before a flowering period of the citruses; S3, applying a fertilizer in a fruit setting period; S4, applying a fertilizer in a fruit growing period and an autumn twig growth period, and watering once to twice after each time of fertilization in the step S1 to S4. The fermentation method has the beneficial effects that due to the addition of an organic carbon fertilizer and a commercial organic fertilizer with high content of organic matters and high content of viable counts, the content of the organic matters in the soil can be increased, the number and types of beneficial microorganisms in the soil can be increased, root system growth can be promoted, the fertilizer utilization rate can be increased, tree vigor can be improved, and the yellowing ratio of the citruses can be reduced; while the organic matters of the soil are increased, the pH value of the soil can be also adjusted, so that the pH value of the soil can be applicable to growth of citrus root systems, yellowing can be reduced, and the quality of the citruses can be improved; as fertilizers are applied in time according to growth rules of the citruses, and the fertilizers are of a reasonable ratio, yellowing caused by nutritional deficiency of the citruses can be avoided, and the quality of the citruses can be improved.

Description

technical field [0001] The invention relates to a fertilization method for improving soil quality of citrus orchards and belongs to the technical field of citrus disease prevention and planting. Background technique [0002] Citrus is an evergreen fruit tree, with continuous physiological activities throughout the year, frequent shoots, long fruit growth period, assimilation and flower bud differentiation in winter. Therefore, it is necessary to pay attention to the combined application and thin application of nitrogen, phosphorus, and potassium fertilizers, so as to meet the needs of the perennial growth and development of orange trees. At the same time, fertilization is best to use organic fertilizers and inorganic fertilizers in combination. According to research, for every 1000 kg of citrus fruits produced, 6 kg of nitrogen, 1.1 kg of phosphorus, 4 kg of potassium, 0.8 kg of calcium, and 0.27 kg of magnesium are required. The ratio of nitrogen, phosphorus and potassium...

[0006] The patent literature with the publication number CN103724084 A has invented a fertilization method, which has many times of fertilization and needs to be mixed with water for each fertilization. Blockage of spraying facilities, and it is not suitable for spraying; the rest of the fertilization is to apply fertilizer to the roots of citrus trees, which will cause the roots of citrus trees to float up and cause root damage
