Abstract

The invention discloses a fertilizer for reducing heavy metal pollution of pear trees and a preparation method thereof. The fertilizer for reducing heavy metal pollution of pear trees comprises the following raw materials in parts by weight: 30-35 parts of tree leaves, 20-25 parts of liquorice, 18-23 parts of egg shell, 20-25 parts of sawgrass, 30-35 parts of salvia prionitis, 25-30 parts of spiderwort, 15-20 parts of red stem grass, 23-27 parts of geranium wilfordii, 15-20 parts of benziothiazolinone, 45-55 parts of cow dung, 20-25 parts of humic acid, 30-35 parts of acetic acid, 1-10 parts of water and 8-12 parts of tartaric acid. The fertilizer disclosed by the invention can convert the heavy metal ions, such as, Pb, Cd, As, Hg and Cr in soil into nonionic state, so as to reduce the damage of heavy metal to the fruit; the fertilizer can change a soil hardening structure, can correct the acid-base balance of soil, can boost the decomposition and absorption of the organic fertilizer and can restrain soil bacteria; the fertilizer can increase the effective silicon content of soil, can boost the absorption of the fruit trees for the nutrition in soil and can obviously increase the fruit yield and quality; and the fertilizer also has the effects of preventing plant diseases and insect pests and increasing the fruiting rate and will not cause the secondary pollution.

Description

technical field [0001] The invention relates to a fertilizer for reducing heavy metal pollution of pear trees and a preparation method thereof, belonging to the field of fruit tree planting. Background technique [0002] Pear, the name of the fruit, is a plant of the genus Pyrus in the family Rosaceae, a perennial deciduous tree fruit tree, with ovate leaves and white flowers. Generally, the color of pears is golden or warm yellow on the outer skin, and bright white inside, tender and juicy. The taste is sweet, the core taste is slightly sour, cool and sexy. Because pear tastes good, and has the effects of clearing away heat and reducing phlegm, moistening lung and relieving cough, it is deeply loved by consumers. [0003] For a long time, in order to increase production and income, the long-term excessive use of various chemical fertilizers in the soil, coupled with the pollution of water quality, etc., has led to the decline of soil fertility, the lack of organic matter, ...
