Embodiment 1

[0021] Embodiment 1: a kind of method for improving saline-alkali soil, is characterized in that concrete steps are as follows:

[0022] (1) Drill holes in the soil to improve the compaction of the soil. The soil is sloping lawn. The holes are drilled with a ф80mm ground drill. The hole spacing is 20cm, and the depth of the holes is 20cm. Loose soil is used to improve the compaction of the soil;

[0023] (2) Fertilization: Apply fertilizer to improve soil fertility in the drilled holes. The fertilizer formula adopts microbial organic fertilizer, fine sand and plant growth regulator after greening waste treatment, and its volume ratio is 70:19:1. Wherein, the microbial organic fertilizer after the greening waste treatment adopts anaerobic bacteria fermented organic fertilizer, including actinomycetes and bacillus;

[0024] (3) Irrigation: Irrigate the soil after perforating and fertilizing, so that the fertilizer can penetrate into the soil for easy absorption.

[0025] The pl...

Embodiment 2

[0026] Embodiment 2: a kind of method for improving saline-alkali soil, is characterized in that concrete steps are as follows:

[0027] (1) Drill holes in the soil to improve soil compaction. The soil is sloping lawn. The hole is drilled with a ф100mm ground drill. The hole spacing is 25cm and the depth of the hole is 25 cm. Loose soil is used to improve the soil compaction;

[0028] (2) Fertilization: Apply fertilizer to improve soil fertility in the drilled holes. The fertilizer formula adopts microbial organic fertilizer, fine sand and plant growth regulator after greening waste treatment, and its volume ratio is 75:24:1. Wherein, the microbial organic fertilizer after the greening waste treatment adopts anaerobic bacteria fermented organic fertilizer, including actinomycetes and bacillus;

[0029] (3) Irrigation: Irrigate the soil after perforating and fertilizing, so that the fertilizer can penetrate into the soil for easy absorption.

Abstract

The invention relates to a method for improving soil in a saline-alkali land. The method is characterized by comprising the following steps: (1) punching the soil and improving the harden degree of the soil; (2) fertilizing; and (3) watering. A fertilizer applied to the method for improving the soil in the saline-alkali land adopts a formula containing a microorganism organic fertilizer after greening waste treatment, fine sand and a plant growth regulator at a volume ratio of (70-80):(19-29):1. The method has the technical effects and advantages that 1, the punching fertilizing excellently solves the phenomenon that a sloping lawn cannot normally absorb water fertilizer and causes the lawn to vigorously grow; 2, the border trees treated by taking a punching ventilating nutriment-replenishing measure are characterized in that the blade color is deeper, the blade is fat and the leaves are lush; 3, the harden soil is loosened and the water-holding and fertilizer-retaining capabilities of the soil are enhanced; 4, the soil is improved and fertilized; and 5, the environmental protection is benefited.

Description

(1) Technical field: [0001] The invention relates to a method for improving saline-alkali soil, in particular to a method for improving the performance of water and fertilizer retention in saline-alkali soil. (2) Background technology: [0002] With the continuous development of urban landscaping construction, the requirements for it are getting higher and higher. It is necessary to ensure high-quality garden landscape effects and to ensure that the greening effect can be maintained for a long time. [0003] Current status of plant growth: (1) Current status of street trees: the main street tree, Fatong, shows early withering phenomenon, which is manifested as: poor growth, small and yellow leaves, sparse buds and leaves, yellow and burnt edges of leaves, and early fall of leaves in autumn , germination is delayed and rare in spring, and the position of buds and leaves is retracted year by year to the base of the main side branch or near the upper part of the main trunk unti...
