Embodiment 1

[0036] The experiment was carried out in Liyuan, Huairou District, Beijing. The test site is located at 39° north latitude, 116° east longitude, 150m above sea level, the annual average temperature is 11-13°C, the extreme maximum temperature in summer is about 39°C, the extreme minimum temperature in winter is about -18°C, the frost-free period is 190-200 days, and the precipitation is year-round. About 70% of the total is concentrated in summer, and there are often heavy rains in July and August. The tree is 10 years old, tall and big, with a density of 50 trees / 667m 2 , located in the valley near the foot of the mountain (to the east), the canopy density is 0.6-0.9 (average 0.76), the soil moisture condition is good, the soil type is mountain cinnamon soil, and the soil organic matter content is 12.1g / Kg. On May 26, 2006, 7 kinds of cover plants (see Table 1) were sown among the trees respectively. The random block design was repeated 3 times. The area of ​​the plot was 4m×...

Abstract

The invention discloses a method for intercropping a cover plant in glades of cold zones and temperate zones. In the method, smooth brome is mainly planted among tree lines with the crown density of 0.2-0.9, wherein, the distance of the smooth brome from tree stumps is 20-50cm; the specific planting method comprises seeding, weeding, applying fertilizers, cutting and the like. The smooth brome intercropped by the method has the advantages of good cold resistance and drought resistance, strong shade tolerance, perennation and the like, and is applicable to being taken as the cover plant in orchards and artificial woodlands. The smooth brome is taken as the cover plant, which can reduce water loss and soil erosion, improve the population number of natural enemies and reduce the number of pests to reduce damages of the pests to fruit trees or forest trees, and further reduce the consumption of herbicides and pesticides, lower the production cost and reduces the environmental pollution; and the harvested smooth brome is taken as pasture grass, which can also increase the income of farmers.

Description

technical field [0001] The invention belongs to the field of covering plants, and in particular relates to a method for making covering plants in forest open spaces in cold temperate regions. Background technique [0002] The upper part of the orchard or artificial forest is dense and the lower part is relatively open. However, due to the high surface canopy density, it is difficult to grow economically valuable crops, and only shade-tolerant weeds can grow. In order to eliminate the impact of weeds on tree growth, artificial weeding is carried out 2 to 3 times a year, or herbicides are used 2 to 3 times, resulting in bare ground, soil erosion, poor biodiversity, fewer types and quantities of natural enemies, A series of problems such as the occurrence of a large number of food pests, the amount of pesticide usage, the resistance of pests, and the increase in environmental pollution. [0003] Cover plants or cover crops (English name Cover plant or Cover Crop) refer to fast...
