Water soluble fertilizer for controlling candidatus liberibacter of fruit trees

Abstract

The invention relates to the technical field of fertilizer, in particular to water soluble fertilizer for controlling candidates liberibacter of fruit trees. The water soluble fertilizer is prepared from the following raw materials in parts by weight: 20 to 50 parts of composite microbial fungicide, 20 to 300 parts of organic matters, 90 to 120 parts of medium-trace element soil conditioning agent, 300 to 450 parts of water, 75 to 85 parts of water-soluble coal-based mineral potassium humate or water-soluble coal-based mineral sodium humate, 10 to 125 parts of dipotassium hydrogen phosphate, 20 to 300 parts of urea, 50 to 500 parts of potassium tripolyphosphate, 50 to 500 parts of potassium formate, 5 to 15 parts of borax, boric acid or disodium octoborate tetrahydrate, 10 to 50 parts of potassium hydroxide, 10 to 25 parts of organic acid, 5 to 20 parts of EDTA complex trace elements, 3 to 5 parts of AES or AEO, and 0.5 to 1.2 parts of xanthan gum. By adopting the water soluble fertilizer for controlling the candidates liberibacter of fruit trees, the low-solubility salts and precipitation effect can be avoided, a good sustained release effect for the fertilizer can be achieved, the buffering performance of the soil can be apparently improved, the PH value of the acidic soil can be increased, the acidity-alkalinity of the soil can be adjusted, the stability is high, the flocculation resistance can be apparently improved, the orchard environment can be optimized, and a purpose of high quality, high yield and high performance can be achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-soluble fertilizer for the prevention and control of Huanglongbing of fruit trees. Background technique [0002] Fruit tree Huanglongbing is a devastating disease of citrus production in the world. It is caused by a Gram-negative bacterium that is limited to the phloem and can infect a variety of Rutaceae plants, including Citrus, Hovenia, Kumquat and Murata. . At present, the disease is mainly distributed in nearly 50 countries and regions in Asia, Africa, Oceania, South America and North America, and 11 of the 19 citrus producing provinces (municipalities, autonomous regions) in China have been affected by the disease. , often destroying large citrus areas within a few years. Humic acid-containing water-soluble fertilizers have been rapidly developed due to their special biological and nutritional functions. However, due to the limitations of mineral humic acid ra...

Problems solved by technology

Humic acid-containing water-soluble fertilizers have been rapidly developed due to their special biological and nutritional functions. However, due to the limitations of mineral humic acid raw materials and extraction technology, many manufacturers usually artificially add various chemically synthesized plant regulators to fertilizers to improve the effect. , which increases safety hazards. In addition, due to the instability of humic acid colloids, problems such as stratification, sedimentation, low-temperature crystallization, and high-temperature flatulence will occur after long-term storage, which will affect the use effect
