Abstract

A fertilizer composition for improving stress resistance of land planted pear trees comprises arbuscular mycorrhizal fungi, betaine, salicylic acid, ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) ferric-sodium complex (EDDHA-Fe), a chelate zinc fertilizer titanium zinc ethylenediaminetetraacetate, a promoter and fertilizers containing other elements. Contained arbuscular mycorrhizal fungi is capable of substantially improving stress resistance on drought, waterlogging disaster, salt and alkali, high temperature, heavy metal toxicity, toxic organics and the like of pear trees, and promoting absorption of soil mineral nutritional elements by soil. Betaine and salicylic acid are capable of inducing to improve crop resistance on adverse situations such as drought, freeze injury and the like.

Description

[0001] 1. Technical field [0002] The invention relates to a pear tree fertilizer composition, in particular to a fertilizer composition for improving the stress resistance of field-planted pear trees 2. Background technology [0003] The planting of pear trees is mainly based on mountainous areas, saline-alkali, old river beaches, etc., and stresses such as drought, saline-alkali, and freezing damage often occur. Therefore, the fertilizer composition used to improve the resistance of pear trees is an important agricultural resource. Now pear trees There is no fertilizer composition to improve resistance in the world. Li Guozhi et al. reported (CN201210210987) to use fulvic acid, sodium salt of DA-6, 2,4-D, sodium α-naphthalene acetate, gibberellin, zeatin, dimethyl sulfoxide, ethylene glycol monobutyl ether, The composition of sodium tetraborate, zinc sulfate, ferrous sulfate, molybdenum sulfate and magnesium sulfate is a foliar spray preparation for promoting fruit setti...
