specific Embodiment approach 1

[0015] Specific implementation mode one: this implementation mode is a kind of method for setting up reed vegetation on severe soda saline-alkali ground, specifically finish according to the following steps:

[0016] 1. Build the pool ridge: take soil locally, build a pool ridge with a width of 60cm and a height of 40cm, and the height difference between the ground in the pool is less than 5cm;

[0017] 2. Obtain the source of reed:

[0018] In spring, when the soil thaws to more than 50 cm, dig out reed rhizomes with a diameter of 1 cm to 2 cm, cut them into 8 cm to 10 cm rhizome segments, and complete the transplanting of the rhizome segments within 1 to 2 days after digging;

[0019] 3. Drilling:

[0020] Drill holes at a plant spacing of 50cm, a row spacing of 50cm, and a depth of 40cm to 50cm to form planting holes;

[0021] 4. Implantation of reed stem segments:

[0022] Insert 2 to 3 reed rhizomes obtained in step 2 into each planting hole, then fill the planting hol...

specific Embodiment approach 2

[0029] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the height difference of the ground in the pool in Step 1 is less than 3m. Others are the same as the first embodiment.

specific Embodiment approach 3

[0030] Specific embodiment three: one of the differences between this embodiment and specific embodiment one or two is: in the step 3, adopting a spiral drill bit with a diameter of 8cm~10cm is 50cm according to the distance between plants, and the row spacing is 50cm, and the depth is 40cm~50cm to drill hole, forming a colonization hole. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to the technical field of saline-alkali soil ecological treatment, in particular to a method for establishing reed vegetation on heavy soda saline-alkali soil. The method aims to solve the problem that in an existing heavy soda saline-alkali soil vegetation planting process, the alkalization degree is high, soil hardening is firm, and tillage is difficult, accordingly survival of plants is extremely difficult, and vegetation coverage cannot be formed. The method comprises the first step of pool ridge construction, the second step of reed provenance obtaining, the third step of plant hole drilling, the fourth step of reed stem section planting and the fifth step of growth period management. The method has the advantages that the purposes of improving the soil and restoring vegetation are achieved; field operation is convenient, the survival rate is high, and the reed coverage rate in the second year reaches 70%. The method is mainly used for establishing the reed vegetation on the heavy soda saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of ecological control of saline-alkali land, in particular to a method for planting reeds in saline-alkali land with severe soda. Background technique [0002] There are 3.42 million hectares of soda saline-alkali land in the Songnen Plain in Northeast my country. The soil salinity is mainly sodium carbonate and sodium bicarbonate, with poor physical and chemical properties, high pH, ​​high exchangeable sodium content, low soil nutrient content, and poor availability, which severely restricts plant emergence. and growth and development. Among them, the severe soda salinization soil with an alkalization degree of 30% to 45% can only grow a small number of strong saline-alkali-tolerant plants, while those with an alkalization degree greater than 45% are mostly "alkaline patch land" (alkaline patch land vegetation) without vegetation growth. less than 10% coverage). Severe salinization of soil leads to vegetat...
