Problems solved by technology

[0008] In order to solve the problems that the above Elaeagnus eraeae is difficult to form a straight trunk, easy to lodging in the rainy season, and irregular forests in the popularization and application of the Yellow River Delta coastal saline-alkali area, the present invention Provided is a method for planting Eleuthero jujube green forest in the coastal saline-alkali land of the Yellow River Delta

[0024] Planting in coastal saline-alkali land of Dongying City

[0025] (1) In March 2002, in the saline-alkali land along the coast of Dongying City, the common Azalea seedlings were used on the plots with a salt content of 0.8%-1.0%, and 1,000 plants of Elaeoptera were planted by conventional afforestation methods. After surviving, a large number of side branches germinated, causing The trunk growth is poor, and in the rainy season, about 85% of the roots are distributed shallowly, and after being soaked in rainwater, they will be skewed to varying degrees when blown by the wind, and the forest appearance is extremely irregular. From June to August 2005, from the progeny of the seedlings of A. syringae, select a tree with obvious main trunk, straight trunk, smooth bark, less side branch germination, and large and dark green leaves as the mother plant, and place a sign on it;

[0026] (2) From late April to early May 2006, cut the last-year-old branches from the mother tree o...

Abstract

The invention relates to the technical field of planting protection forests in saline and alkaline lands, in particular to a method for planting an oleaster afforestation forest in a saline and alkaline land. The method comprises the steps that firstly, upright tall straight elaeagnus oxycarpa is selected and serves as seed trees, cuttings are obtained from the elaeagnus oxycarpa seed trees through shearing and dipped through ABT 6 rooting powder before cuttage, and elaeagnus oxycarpa shoots are cultivated through the cutting seedling method; secondly, growth of trunks of the elaeagnus oxycarpa shoots is promoted through nutrient and water management, so that the shoots with the trunks upright, tall and straight are cultivated; thirdly, the elaeagnus oxycarpa shoots are transplanted to the coast saline and alkaline land according to an appropriate method and appropriate density. A new salt-tolerant and high-quality oleaster strain suitable for being planted in the yellow river delta region is screened and cultivated through natural screening and artificial induced mutation screening, combined with the characteristics of oleaster, salt-tolerant oleaster seedlings suitable for being appreciated and beautiful in tree appearance are cultivated through reasonable cultivation measures, the high-quality salt-tolerant seedlings are supplied to the yellow river delta region, and common non-salt-tolerant landscape plants are replaced by the high-quality salt-tolerant seedlings.

Description

technical field [0001] The invention relates to the technical field of planting protection forests in saline-alkali land, in particular to a method for planting Elaeagnus sativa green forest in saline-alkali land. Background technique [0002] The Yellow River Delta is located in the northern part of Shandong Province, with 5.3×10 5 hm 2 Saline-alkali land, and the area of ​​saline-alkali land is still increasing by 1.3×10 5 hm 2 The groundwater level in the saline-alkali land of the Yellow River Delta is high and the salt content is high; the content of organic matter, nitrogen and phosphorus is low; the nutrients are unbalanced; the physical and chemical properties of the soil are poor, and it is dry in spring and prone to waterlogging in summer. It is not suitable for the growth of conventional garden plants. Now the landscaping in Dongying mainly adopts the method of digging and replacing soil, which is costly and unsustainable. Once the trees grow up, the trees w...
