Embodiment 1

[0057] A sludge rare earth soaking solution, which is composed of a sludge extract solution and a rare earth solution in parts by weight of 1:1; wherein the sludge extract refers to the sludge:distilled water ratio by weight and number After being mixed at 1:2, place it for 24h and filter to obtain the required sludge extract; the rare earth solution refers to Ce(NO 3 ) 3 ·6H 2 O or La(NO 3 ) 3 ·6H 2 O aqueous solution.

[0058] where Ce(NO 3 ) 3 ·6H 2 The concentration of O rare earth solution is 200, 300, 400 mg.L -1 .

[0059] La(NO 3 ) 3 ·6H 2 The concentration of O rare earth solution is 200, 300, 400 mg.L -1 .

[0060] The sludge used in this experiment was taken from Tianjin Jizhuangzi Sewage Treatment Plant, and tall fescue (tall fescue), a common lawn plant in northern my country, was selected. Festuca arundinacea L.). The rare earth elements are cerium and lanthanum, and cerium nitrate produced by Tianjin Kaitong Chemical Reagent Co., Ltd. is used, a...

Abstract

The invention discloses a method for enhancing activity of salt-stress festuca arundinacea protective enzymes by a sludge / rare-earth mixed seed soaking solution. The sludge / rare-earth mixed seed soaking solution is composed of a sludge leaching solution and a rare-earth solution in a weight ratio of 1:1, wherein the sludge leaching solution is prepared by mixing sludge and distilled water in a weight ratio of 1:2, standing for 24 hours and filtering; and the rare-earth solution is a water solution containing 200-400 mg.L<-1> Ce(NO3)3.6H2O or La(NO3)3.6H2O. The experimental result indicates that the mixed seed soaking can enhance the activity of the three enzymes SOD, POD and CAT in festuca arundinacea under salt-stress conditions.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to urban afforestation, in particular to a method for improving the activity of tall fescue protective enzymes under salt stress by mixing seed soaking liquid with rare earth sludge. Background technique [0002] The characteristics of high efficiency, low cost and low toxicity of rare earths make them show broad application prospects in agricultural production. As a new type of substance to adapt to adverse conditions, rare earths may regulate a series of physiological and biochemical processes in plants through various ways. At present, most of the studies on the biological effects of rare earths are still focused on increasing crop yield, improving crop quality and improving crop stress resistance. Rare earth is not an essential element for life, but because it can promote biological growth at a lower concentration, it is widely used as a measure to increase produ...
