Embodiment 1

[0028] The transplanting method of white elm on saline-alkali land, comprises the steps:

[0029] Step 1, on the sandy loam soil, plow the land 15 to 20 centimeters deep, then apply base fertilizer (the pure N content of the base fertilizer is 25%, P 2 o 5 The content is 5%, K 2 The content of O is 10%), open a small ditch about 3 to 6 cm deep, and evenly scatter the seeds of Elm elm in the ditch, the amount of seed per mu is about 3 to 5 kg, and then spray irrigation (3 to 6 hours per day, continuous Sprinkle irrigation for 3 to 4 days), and seedlings will be generated on the land;

[0030] In the second step, field management such as weeding and soil loosening is carried out at the seedling stage until the seedlings grow to a height of 15-20 cm, and the seedlings are thinned so that the distance between the seedlings is 30-50 cm. 3 steps of transplanting;

[0031] The third step is to excavate the planting ditch 1 on the saline-alkali land, the width of the planting ditc...

Abstract

The invention relates to a method for transplanting Ulmus pumila trees on saline and alkaline land, and belongs to the technical field of forestry. According to the method for transplanting Ulmus pumila trees on saline and alkaline land, provided by the invention, water storage channels and concealed pipes are arranged at both sides of a planting ditch, thereby ensuring the moisture of soil in the planting ditch; meanwhile, a pH-sensitive hydrogel is laid on the bottom of the planting ditch, so that when the moisture content in the soil is low and backward infiltration of underground water of the saline and alkaline land is caused accordingly, the saline and alkaline land causes the pH-sensitive hydrogel to be quickly expanded and absorb the water, so the saline and alkaline water is adsorbed in the hydrogel to prevent the further upward infiltration of the water and avoid the salinization and alkalization of the Ulmus pumila planting soil; and when enough moisture is supplemented again in the water storage channels, the moisture drives an acidic fertilizer in the soil of a planting region to infiltrate downwards, the pH environment of the pH-sensitive hydrogel is changed to neutral, and shrinkage and dewatering of the gel occur, so that the moisture infiltrates downwards, and saline and alkaline components are taken to the underground, thereby further restoring a favorable growing environment for the vegetation.

Description

technical field [0001] The invention relates to a method for transplanting white elm on saline-alkali ground, belonging to the technical field of forestry. Background technique [0002] Land salinization is one of the major problems of land degradation in the world today. my country is mainly distributed in the North China Plain, Northeast Plain, Northwest Inland and coastal areas. The main feature of saline-alkali land is that it contains more water-soluble salt or alkaline substances. Due to the high salinity and high alkalinity, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. There are often white salt deposits on the soil surface, poor ventilation and water permeability, and serious plant wilting. , poisoning and root rot death. The hazards of saline-alkali land have caused a large number of low-yield fields and poor farmers, making it difficult to use the soil resources in the area, and the comprehensive agricultu...
