A kind of correction method of citrus iron deficiency chlorosis

Abstract

The invention discloses a treatment method for iron-deficiency yellowing of citrus. For the iron-deficiency yellowing citrus, spray fertilizer on the leaf surface first, and then carry out soil improvement. After 5-10 days of soil improvement, soil fertilization is carried out; the leaf surface is sprayed with chelated iron Fertilizer, can quickly realize the regreening of yellowed leaves, relieve the symptoms of citrus yellow leaves, use soil amendments to reduce soil alkalinity, improve soil aggregate structure, release solidified iron in the soil, and increase the effective iron content in the soil; Iron fertilizer, supplements a large amount of available iron elements to the root system in the soil, treats both internal and external, and achieves the technical purpose of long-term and effective correction of iron-deficiency chlorosis of citrus. The iron-deficiency chlorosis correction method of citrus can be effectively relieved within 15-30 days by using the method for treating citrus iron-deficiency chlorosis, and the cost is low and recurrence is not easy.

Description

technical field [0001] The invention relates to the technical field of yellowing treatment of fruit trees, in particular to a treatment method for iron-deficiency yellowing of citrus. Background technique [0002] Citrus has the most important economic status and the widest cultivation area in southern my country. It is planted in many subtropical regions and countries. Most of the citrus production areas in my country are distributed in mountainous areas with poor geographical location and soil conditions. Due to serious nutrient leaching or soil Unsuitable pH makes it difficult for citrus seedlings to absorb nutrients. In recent years, the main producing areas of citrus in my country have experienced extremely common and increasingly serious symptoms of nutrient deficiency, and with the increase of fruiting years, large areas of nutrient deficiency yellowing, swollen and even bursting of leaf veins have appeared successively; in calcareous soil Iron-deficiency chlorosis is ...

Problems solved by technology

Iron deficiency in plants directly leads to reduced chlorophyll content and subsequent reduction in net photosynthetic efficiency

Treatment of iron deficiency in citrus is difficult due to the easy conversion of iron to the ferric form, which is not available to plants, and the immobility of iron in plants, and the application of inorganic iron fertilizers to iron-deficient soils is often ineffective
