Problems solved by technology

For example, considering that Songnen Grassland is located in the interlaced area of ​​agriculture and animal husbandry, and has rich straw resources, straw cuttings have been developed to improve degraded grasslands; mulching straws to improve the soil microenvironment, supplementing herbaceous plants such as star grass, wild barley and sansevieria to improve degraded grasslands; and By transplanting Leymus chinensis to restore degraded grassland, however, transplanting Leymus chinensis requires irrigation management in the later stage, which restricts the large-scale application of this technology
In recent years, the Northeast has also developed the technology of growing rice on saline-alkali land. However, the salinized land in the Northeast is in a semi-arid area, with an annual rainfall of only 300-400 mm, while the annual water consumption for planting rice has reached 1600 mm. It is sustainable to develop rice in saline-alkali land near the river. However, most of the saline-alkali land in Northeast China is far away from the river. Planting rice on a large scale in the saline-alkali land in this area will inevitably lead to an extreme drop in groundwater level and depletion of water resources, causing a series of ecological problems. question

specific Embodiment approach 1

[0032] Embodiment 1: This embodiment is a method for recovering leguminous plants in saline-alkali land, specifically according to the following steps:

[0033] One, use a plow to dig a plurality of ditches in parallel in the saline-alkali soil, and the saline-alkali soil dug out from the ditch is evenly piled up on both sides of the ditch to form a saline-alkali soil isosceles triangle; the section of the ditch is an inverted isosceles triangle, and the ditch The width L at the horizontal plane is 5cm-15cm, and the depth H of the ditch is 5cm-15cm;

[0034] Two, wind-sand soil is applied in the ditch that step 1 is opened to the highest point contour of the saline-alkali soil isosceles triangle in step 1 to the highest point of wind-sand soil;

[0035]3. Apply the leguminous plant seeds to the wind-blown sandy soil in the ditch of step 2 with a planter, the application amount of the leguminous plant seeds is 20kg~40kg / ha saline-alkali land, and the legume plant seeds are high...

specific Embodiment approach 2

[0038] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the width L at the horizontal plane of the ditch is 5 cm, and the depth H of the ditch is 5 cm. Others are the same as the first embodiment.

specific Embodiment approach 3

[0039] Embodiment 3: The difference between this embodiment and Embodiment 1 is that in step 1, the width L of the ditch at the horizontal plane is 10 cm, and the depth H of the ditch is 10 cm. Others are the same as the first embodiment.

Abstract

The invention relates to a method for recovering pod-bearing plants in saline and alkaline lands, and aims to solve the technical problems that a conventional saline and alkaline land transplanting method needs continuous later irrigation management and large-scale popularization and application of species is limited. The method comprises the following steps: I, forming furrows by using a plough; II, applying aeolian sandy soil into the furrows; III, sowing pod-bearing plant seeds into the aeolian sandy soil by using a sowing machine; IV, compacting the aeolian sandy soil in the furrows by using a compactor. The method provided by the invention is low in cost and easy to popularize and has late economic benefits. The method is applicable to recovery of the pod-bearing plants in the saline and alkaline lands.

Description

technical field [0001] The invention relates to a method for restoring leguminous plants in saline-alkali land. Background technique [0002] Foreign research status: Soil salinization is a worldwide problem (Szabolcs 1989). Since the beginning of the 20th century, the restoration and management of salinized land has a history of more than 100 years (Qadir et al. 2001). International research on saline-alkali land treatment mainly focuses on farmland soil. In terms of treatment technology, on the one hand, based on the laws of water and salt migration in saline-alkali soil, physical methods are adopted, such as turning rakes, covering straw, and setting ditches to build ridges, etc. to improve the surface structure. , improve water infiltration, reduce water evapotranspiration, block the rise of salinity, or directly dig trenches to drain and wash salt, so as to reduce the salinity of the topsoil and facilitate plant growth (Bakker et al.2010a,b); on the one hand, it is base...
