Embodiment Construction

[0009] 1. Conditions for implementing strip supplementary broadcasting

[0010] The annual precipitation is above 350 mm, and the rain and heat in the same period are conducive to the growth of grass in the northern region. The grassland is moderately and severely degraded, the native vegetation coverage is below 40%, and the grass height is below 30 cm.

[0011] 2. Technical requirements

[0012] (1) Variety selection

[0013] The re-sowing varieties selected for the improved section are Elymus nutans, Bromus inermis, Leymus chinensis, and Medicago falcata, which are suitable for growth in the northern region. Cultivated forage species.

[0014] (2) Supplementary broadcast method

[0015] In parallel with the slope aspect, the 20-meter strip-shaped re-seeding plots are shallowly turned every 40 meters to form a strip-like distribution of the supplementary-seeding plots and the original vegetation, that is, the width of the strip-shaped supplementary sowing is 20 meters, a...

Abstract

The invention discloses a novel technology for improving moderately or severely degraded meadow steppes in a belt-shaped after culture manner. Particularly for the northern degraded meadow steppes, the invention discloses a reasonable and reasonable improvement technology; and after shallow plowing, good artificial grass is after cultured, so that the physicochemical conditions of the soil are scientifically improved, the grass yield and grass quality of the degraded steppes are improved and a positive role in protecting the abundant species resources of the meadow steppes, promoting the ecosystems of the steppes to realize virtuous circle and accelerating the sustainable development of animal husbandry is given a full play.

Description

technical field [0001] The invention relates to a method for improving meadows and grasslands, in particular to a new method for improving degraded temperate meadows and grasslands in pastoral areas in northern my country by adopting strip-shaped supplementary sowing. Background technique [0002] Temperate meadow steppe is a major grassland type in northern my country. It is a grassland vegetation composed of perennial mesophytic and wide-spread xerophytes (clump grasses and rhizome grasses) as the dominant species. This type is located in the transition zone from forest to grassland, and has obvious regional characteristics. It is mainly distributed in the Daxingan Mountains and the high plains and low hills in the west and east of the Mountains. It is the best grassland in northern pastoral areas such as Inner Mongolia. An important ecological link connecting boreal forests and grasslands. The national area is about 600 million mu, accounting for 11.3% of the total grass...
