Embodiment 1

[0059] 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.

[0060] where Ce(NO 3 ) 3 ·6H 2 The concentration of O rare earth solution is 200, 300, 400 mg.L -1 .

[0061] La(NO 3 ) 3 ·6H 2 The concentration of O rare earth solution is 200, 300, 400 mg.L -1 .

[0062] method:

[0063] (1) Air-dry the fetched sludge under natural conditions, and use a 4 mm sieve to remove large particles for later use;

[0064] (2) Then put the sludge in distilled water in a ratio of 1:2 by weight and place it in a container for 24 hours, then filter to obtain the required sludge extract;

[0065] (3) Ce(NO 3 ) 3 ·6H ...

Abstract

The invention discloses a method for improving the salt tolerance of festuca ovina by hybrid seed soaking liquid of sludge and rare earth. The hybrid seed soaking liquid of the sludge and the rare earth is composed of a sludge leaching solution and a rare earth solution with the ratio of the weight part of the sludge leaching solution to the weight part of the rare earth solution as 1:1. The sludge leaching solution is formed by the facts that the ratio of the weight part of the sludge to the weight part of distilled water is 1:2, the sludge and the distilled water are mixed, then placed for 24 hours and filtered to obtain the needed sludge leaching solution. The rare earth solution is the water solution of Ce (NO3) 3.6 H2O or La (NO3) 3.6 H20 with the concentration of 100-300mg. L-1. Experiment results show that the hybrid seed soaking liquid of the sludge and the rare earth has a certain stabilizing effect on malonaldehyde and praline of the festuca arundinacea under salt stress and on relative electrical conductivity.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to urban greening, in particular to a method for improving the salt tolerance of tall fescue by adopting sludge rare earth mixed seed soaking liquid. Background technique [0002] On the one hand, rare earth can promote the growth of root system, and on the other hand, it can promote the occurrence of adventitious root, which plays an extremely important role in the division of cells and the formation of root system. It can increase the chlorophyll content of plants, deepen the leaf color, and increase the respiration intensity of the value, thereby accelerating the transformation of matter and energy. It can promote the growth of forest tree seedlings, and promote the absorption and accumulation of nutrients, so that high-quality seedlings can be obtained and the survival rate after leaving the nursery can be improved. Promote the growth of plant leaves and leaf a...
