Problems solved by technology

However, in saline-alkaline areas, due to excessive soil salt accumulation, it is very difficult for tree roots to absorb water and nutrients, which destroys the normal water metabolism in trees, causing physiological phenomena such as drought, wilting, or growth stop, or even death. cause considerable difficulty

Embodiment 1

[0012] According to the groundwater level and saline-alkali level, the ground of the saline-alkali land (salt content 0.8%-1.5%) in Binzhou Beihai New District is properly raised into a mound shape, with a slope between 18°-45° and a maximum height of 1.5-2.0m. Salt pine, a plant with strong salt and alkali tolerance, is ridged along the slope for 30 to 40 cm. Afforestation fish scale pits are built on the ridges according to the size of the salt-tolerant seedlings. 7.0 kg of decomposed cow dung is applied to each fish scale pit. The seedlings are planted using the tree planting method, and the soil is cultivated around the afforestation pit to form a circular sill, and the open ditch drains salt along the water. The two-year survival rate of salt pine reaches 85%.

Embodiment 2

[0014] According to the groundwater level and saline-alkali level, the ground of the saline-alkali land (salt content 0.6%-1.2%) in Binzhou Beihai New District is properly raised into a mound shape, with a slope between 20°-40° and a maximum height of 1.6-2.1m. Plant white wax with strong salt-alkali tolerance, ridges of 20-35 cm along the slope, afforestation fish scale pits are built on the ridges according to the size of the salt-tolerant seedlings, and 6.0 kg of decomposed cow dung is applied to each fish scale pit. Planting seedlings with the "Yi Mention" tree planting method, soil is cultivated around the afforestation pit to form a circular sill, and the open ditch drains salt along the water. The two-year survival rate of white wax reaches 80%.

Embodiment 3

[0016] According to the groundwater level and saline-alkali degree, the ground of the saline-alkali land (salt content 0.5%-1.1%) in Binzhou Beihai New District is properly raised into a mound shape, with a slope between 15°-35° and a height of 1.0-1.8m. Amorpha fruticosa, a plant with strong salinity and alkalinity, is ridged along the slope for 20-30 cm. Afforestation fish scale pits are built on the ridges according to the size of the salt-tolerant seedlings, and 5.0 kg of decomposed cow dung is applied to each fish scale pit. The seedlings are planted using the method of stepping and lifting, and the soil is cultivated around the afforestation pit to form a circular sill, and the open ditch drains salt along the water. The two-year survival rate of Amorpha fruticosa reaches 75%.

Abstract

A method improving tree plantation survival rate in a severe saline-alkali soil and belongs to the field of saline-alkali greening. The method is characterized by comprising the following steps of (1) properly lifting a ground to an earth mound according to underground water level and saline-alkali degree, (2) selecting high saline-alkali-resistant plant types, (3) ridging for 20 to 40cm along the inclination of the earth mound with a gradient between 15 to 45 degrees and building afforestation fish-scale pits on the ridges according to size of saline-resistant seedlings, (4) applying 4.0 to 8.0kg decomposed cow manure to each fish-scale pit, (5) employing a planting method of burying soil for three-times, stepping for twice and lifting the seedling for once, (6) ridging soil on the periphery of the fish-scale pits to form round sills, and (7) discharging salt along water through an open trench. By the use of the method, garden greening plantation survival rate in the severe saline-alkali (with salt content of 0.5% to 1.5%) can be effectively improved and survival rate can reach more than 70%.

Description

technical field [0001] The invention belongs to the field of saline-alkali land greening, in particular to a method for improving the survival rate of tree planting in severe saline-alkali land. Background technique [0002] Saline-alkali soil refers to those soils with high salt content and pH greater than 9, which make it difficult to grow plants, especially crops. According to the amount of salt and alkali, it can be further divided into mild (0.1%-0.25%), moderate (0.25%-0.5%) and severe saline-alkali (0.5%-0.6%). The formation of saline-alkali land is often the result of the joint action of many aspects. If the soil itself contains more minerals, these minerals will easily become the source of saline-alkali accumulation after weathering. Groundwater also plays a big role, and groundwater always contains salt. When the groundwater level is high and the area is relatively dry, the groundwater will evaporate due to capillarity, and the salt will remain in the soil. If t...
