Embodiment 1

[0028] Embodiment 1 A kind of method of introducing American bamboo willow to carry out saline-alkali land original soil greening

[0029] Step 1 Saline-alkali land original soil preparation

[0030] The test site is located in the coastal heavy saline-alkali land in the north of Weifang City, Shandong Province. The pH of the surface soil layer is 8.5, and the salt content is between 18,000 and 20,000 ppm. Except for saline-alkali tolerant plants such as Suaeda salsa, reed and tamarisk, there is no other vegetation growing.

[0031] Before planting, weeds were removed from the plantation land, and the land was plowed mechanically. During the deep plowing process, 500 times liquid of 50% carbendazim wettable powder was used to disinfect the soil, and the spraying rate was 100g / ㎡; Base fertilizer; the base fertilizer is 3t / mu of decomposed farmyard manure.

[0032] Ridges are formed in the planting area, the width of the ridge is 0.8m, and there is a drainage ditch with a widt...

Embodiment 2

[0050] Example 2 The effect of cutting size on the survival rate of Bamboo willow cuttings

[0051]According to the method of Example 1, the introduction of American bamboo willow is carried out, and the cutting specifications selected in the preparation of the bamboo willow cuttings are changed in step 2, and examples 2 to 5 are carried out; see Table 1 for details;

[0052] Table 1 Specifications of cuttings

[0053]

[0054] 30 days and 60 days after the cutting, the survival rate of the cuttings was counted, as shown in Table 2;

[0055] Table 2 Survival rate of bamboo willow cuttings

[0056]

[0057] As can be seen from the above table, the cutting survival rate of embodiment 4 is obviously higher, that is, the cutting size selected in step 2 to prepare bamboo willow cuttings is preferably 1.6 cm in cutting stem thickness, 22 cm in cutting length, and 4 side buds.

Embodiment 6

[0058] Example 6 The effect of landfill matrix cutting rooting speed

[0059] Carry out the introduction of American bamboo willow according to the method of embodiment 1, change the landfill substrate used in the cutting of step 4, carry out embodiment 6~10, specifically see table 3;

[0060] Table 3 Distribution ratio of various components of landfill matrix

[0061]

[0062] 30 days and 40 days after cutting, the rooting rate of cuttings is counted, specifically see Table 4;

[0063] The rooting rate of table 4 bamboo willow cuttings

[0064]

[0065] As can be seen from the above table, the rooting rate of the bamboo willow cuttings of embodiment 9 is significantly higher, that is, the landfill substrate used in the step 4 cuttings is preferably peat soil: oyster shell powder: sawdust: pine needles: camellia pollen: jujube stone powder and 7:3:3:2:0.5:4 mass ratio mixing preparation.

Abstract

The invention provides a method for greening saline-alkali soil land natural soil by introducing America bamboo willows. The method comprises the steps of saline-alkali soil natural soil arrangement, preparation of shoots for cutting of the bamboo willows, pretreatment before cutting, cutting, irrigation, topdressing, and diseases and insect pests prevention and control. In the step of saline-alkali soil natural soil arrangement, a machine is adopted to conduct land deep tillage, and in the process of deep tillage, a 400-500 fold solution of 50% carbendazim wettable powder is adopted to disinfect soil, and the spraying amount is 80-120 g / m<2>; base fertilizer is evenly and sufficiently applied, and the base fertilizer is 2-3 t / mu of decomposed farmyard manure. Ridges are formed in a planting area, the width of the ridge surface is 0.8 m, drainage ditches are formed between the ridges, the width of the drainage ditches is 0.6 m, the depth of the drainage ditches is 0.5 m, and salt drainage hidden pipes are buried in the drainage ditches. Through the adoption of the method for greening the saline-alkali land soil natural soil by introducing the America bamboo willows, compared with a conventional method, the preservation rate of young forests is increased by 13.1-22.6%.

Description

technical field [0001] The invention relates to a method for afforesting saline-alkali land, in particular to a method for introducing American bamboo willows to perform original soil afforestation of saline-alkali land. Background technique [0002] With the rapid development of my country's economy and society, the scale of cities continues to expand. Eastern coastal areas such as the Yellow River Delta High-Efficiency Ecological Economic Zone around the Bohai Sea, Tianjin Binhai New Area, Hebei Caofeidian New Area, Liaoning Coastal Economic Belt, Shanghai Pudong New Area in the Yangtze River Delta, Jiangsu Coastal The economic belt and others began to develop towards the coastal beaches. The formerly desolate coastal area is undergoing large-scale development in full swing. The development of the above areas will inevitably bring about the construction of a large number of urban landscaping projects. However, whether it is intertidal tidal flats, sea retreats, marine pla...
