Problems solved by technology

[0005] In order to solve the problems of long construction time and high cost of large-scale water-saving irrigation projects in the prior art, lack of universality of water-saving irrigation agronomic technology, and low cutting effect and survival rate of traditional punching methods, the present invention proposes a new energy-saving irrigation method. Water-irrigated afforestation method, the inventor found that there is a certain correlation between the cutting method and the punching method, and the combination of the two for water-saving irrigation afforestation, compared with the traditional afforestation irrigation water consumption of 450-900m 3 / hm 2 Compared with the traditional method, the water consumption is 1 / 720-1 / 360, which not only greatly saves fresh water resources, improves water use efficiency, reduces afforestation costs, but also greatly reduces afforestation time under the premise of ensuring survival rate and preservation rate

Embodiment 1

[0066] A kind of water-saving irrigation tamarisk afforestation method, comprises steps as follows:

[0067] 1. Selection of tree species: Chinese Tamarix

[0068] 2. Selection of afforestation sites: The salinity of the soil generally requires 0.5-0.9% chloride saline soil, and the soil pH value is 8.0-8.4. The soil texture of the plantation land is sandy soil.

[0069] 3. Afforestation time: before germination in spring.

[0070] 4. Preparation of cuttings: Select the seedlings that are 1 to 2 years old, have a base diameter greater than 0.8cm, a small head diameter greater than 0.5cm, and are free from diseases and insect pests. It is cut into 18-20cm cuttings, graded according to diameter, counted and bundled.

[0071] 5 Cuttings soaking: Soak the cut cuttings in clean water for 1 day, change the water every 12 hours, and cut the cuttings in time after the water comes out.

[0072] 6. Key points of afforestation technology: the method of using agricultural high-pressur...

Embodiment 2

[0093] The difference with embodiment 1 is:

[0094] Soaking cuttings: Soak the cut cuttings in clear water for 3 days, change the water once every 12 hours, cuttages in time after the water comes out, and the rest of the conditions are the same as in Example 1.

[0095] The long soaking time will allow the cuttings to absorb water more fully, which helps to improve the survival rate. The survival rate of the shelterbelt planted in this embodiment is 93%, and the preservation rate is 84%.

Embodiment 3

[0097] The difference from Example 1 is that the spacing between plants and rows is 1m×3m, and the rest of the conditions are the same as in Example 1.

[0098] The wide spacing between plants and rows helps to optimize the distribution of nutrients and water in the sandy soil, and avoid vicious competition. The survival rate of the shelterbelts planted in this embodiment is 93%, and the preservation rate is 86%.

Abstract

The invention relates to the technical field of afforestation, in particular to a water-saving irrigation afforestation method and application thereof. A cuttage method and a punching method have certain relevance and are matched for water-saving irrigation afforestation, compared with the irrigation water consumption of 450-900 m<3> / hm<2> of traditional afforestation, the water consumption is 1 / 720-1 / 360 of that of a traditional method, fresh water resources are greatly saved, the water utilization rate is increased, the afforestation cost is reduced, and the afforestation time is greatly shortened on the premise that the survival rate and the preservation rate are guaranteed.

Description

technical field [0001] The invention relates to the technical field of afforestation, in particular to a water-saving irrigation afforestation method and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Water shortage is a major threat to forestry development in arid and semi-arid areas. my country's agricultural and forestry irrigation water mainly depends on natural precipitation, surface runoff and groundwater resources. Especially in coastal saline-alkali areas, on the one hand, there is a shortage of fresh water resources, and the groundwater resources are mostly salt water and brackish water, with low utilization rates; on the other hand, plants are...
