Benefits of technology

In this patented method described in the patented text, there were various ways to enhance or restore ground fertility without causing harmful side reactions like deforestations. By utilizing specific techniques based upon factors like sunlight availabilities, nitrogen levels, mineral concentrates, and other factors, these processes resulted in significant increases in yields compared to traditional farming practice. Overall, this technology provides technical means for creating stable and economical grassland production bases.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the ecology equilibrium between different regions within the Lesser Land (Loess Plane) during periods when rainwater from both urban parts can be absorbed into fresh wetland or underground without causing harmful effects like decreased crop yields due to overgrazing crops. Existing solutions involve adding expensive fertilizers or reducing sedimentary basin depth, making them less effective at reconstructing ecosistence around these zones.

Embodiment 1

[0052] Example 1. An example of fertilization and restoration of Nandi fertilization in the barren land of Nanxiaohegou, Qingyang, Gansu

[0053] Introduction to the test site: The test site is located in Nanxiaohegou, Qingyang City, Gansu Province (hereinafter referred to as the sample plot) in the hinterland of the Loess Plateau, with an area of ​​600 square meters, a length of 40m, and a width of 15m.

[0054] Nandi planting method: Select Nandi with a stem thickness of 1-2cm and full lateral buds to cut the stem segments. Each stem segment contains 2-3 lateral buds, and the length of the stem segment is 20-30cm. Soak the stem section in 25% carbendazim water for 18 hours to sterilize, and make the tissue absorb water completely until the lateral buds germinate. Plow the sample land before planting, and after plowing, the depth reaches 30 cm. The sample land is 100 cm long and 100 cm wide, and the ditch width is 20 cm, and the ditch depth is 10 cm.

Embodiment 2

[0065] Example 2: An example of soil and water conservation in Nandi on the slope of Liulin in Shanxi

[0066] Introduction to the test site: The test site is located in Liulin County, Shanxi Province, with an area of ​​1,200 square meters, a length of 40m, and a width of 30m. The slope is 40°, which is barren land.

[0067] Planting method of Nandi: Select Nandi with a seedling age of 2 years, remove the leaves of Nandi, and remove weeds and other ground covers before planting. Dig a hole-shaped soil pit with a diameter of 30cm and a depth of 20cm. Pour two-thirds of the water into the pit and make the pit into mud for planting seedlings. The roots of the seedlings must be in the mud in the pit and cover with two-thirds of the dry Soil prevents surface compaction. The planting holes are planted in a plum-shaped arrangement with a spacing of 40 cm, and a total of 2,400 seedlings. Spray 2-4D butyl ester in mid-April of the second year of planting for weeding, with a dosage o...

Abstract

The invention relates to a method for ecological restoration of marginal land of the loess plateau by using an energy crop triarrhena lutarioriparia, which comprises the following steps: S1, collecting and collating a spatial distribution map of meteorological data in the loess plateau region in recent years and an existing land type map of the region in combination with a regional map meeting thegrowth conditions of the triarrhena lutarioriparia, using geographic information system software for map layers piling, map layers piling the mentioned three maps, and determining the region suitablefor ecological restoration by using energy crop triarrhena lutarioriparia; S2, dividing the suitable restoration region determined in the step S1 into three types of marginal land to be restored according to land types; and respectively carrying out ecological restoration on the three types of marginal land to be restored by adopting different triarrhena lutarioriparia planting methods. The method for ecological restoration of marginal land of the loess plateau by using energy crop triarrhena lutarioriparia has the advantages that, a suitable method for planting and restoring the triarrhena lutarioriparia is configured according to different types of marginal land of the loess plateau region and local conditions, and economic benefits are generated by the harvest of biological refining raw materials and biomass power plant raw materials on the ground every year, so that the economic benefits and the ecological benefits are both achieved.
