Abstract

The invention provides anti-seepage sand containing catechin. The anti-seepage sand comprises catechin and further comprises gellan gum, potassium chloride fertilizer, zeolite powder, hydrogen-based bentonite, fishskin glue powder, sodium carboxymethyl cellulose and polyacrylamide. The invention further provides a method for planting salix matsudana in saline-alkali soil by utilizing the anti-seepage sand. The method is characterized by comprising a land preparation step. According to the land preparation step, a tree pit shape is dug to be in a pan bottom shape, the bottom is round, a middle part has a gradient, and the gradient is 30-60 degrees. The anti-seepage sand containing catechin has an effect of improving and maintaining soil temperature.

Description

technical field [0001] The invention relates to anti-seepage sand containing catechin and a method for planting willow in saline-alkali land by using the anti-seepage sand, belonging to the field of saline-alkali land improvement greening. Background technique [0002] Dry willow (Salix matsudana Koidz) is a deciduous tree with a height of 18 meters and a diameter at breast height of 80 centimeters. It belongs to Salix family and Salix. Branches obliquely upward, crown wide and round, bark dark gray-black, longitudinally split, branches erect or oblique, brownish-yellow-green, then brown, glabrous, young branches hairy, buds brown, slightly hairy. [1] A sun-loving, cold- and drought-tolerant plant, distributed in North America, Europe, Russia, China, Canada, Colombia, and Japan. It has greening and ornamental value. It grows at an altitude of 10 meters to 3,600 meters, often in arid or wetlands. [0003] Plant resources in coastal saline-alkali areas are relatively poor. ...
