Purification method of single wild grass crabgrass in natural grass-made orchard

Abstract

The invention discloses a purification method of single wild grass variety crabgrass in a natural grass orchard, and relates to the field of purification methods of mixed wild grass varieties. The method comprises the following steps of two-time rotary tillage and four-time mowing. Weeds such as broad-leaved weeds and the like are cut and uprooted through mechanical equipment in an early stage, reproduction organs are cut off at a later stage, and only single crabgrass is left to form a natural turf. The height of the crabgrass turf is moderate, and the quality of the turf is good, so that theturf can be used for moisture preservation and cooling of fruit trees, water and soil loss can be prevented, the small climate of an orchard can be adjusted, a good habitat condition is provided forinsects, the insects can be prevented from climbing onto the trees, breeding of beneficial insects can be accelerated, and the orchard tends to be more natural and ecological. After purification treatment for one year, the purification process in following years becomes easier and easier, and if the area of the orchard is large enough, no dead angle exists for purification. No special interventionis needed after three years, cost is low, effectiveness is fast, and attractiveness and the functionality of the produced crabgrass turf is integrated, so that the method is a preferred mode for cultivating turfs in natural grass orchards, and the method is suitable for large-scale promotion and application.

Description

Technical field [0001] The invention relates to the field of methods for purifying mixed wild grass seeds, in particular to a method for purifying a single wild grass species crabgrass in a natural grass orchard. Background technique [0002] In natural grass orchards, there will be a variety of wild weeds, including broadleaf grass, crabgrass, purslane, setaria, etc. The weeds vary in height, grow chaotically, there are many pests, and many weeds are important for fruit trees. The sunlight, temperature, moisture, etc. required for the normal growth of the plant have varying degrees of influence, which is not conducive to the cultivation of high-quality fruit in the orchard. Therefore, a grass that is conducive to the growth of fruit trees in the orchard is specially cultivated to form a single turf, which is proven to be natural The development direction of grass orchard. [0003] Crabgrass, an annual grass family, is a wide-spread mesophyte with a fairly wide ecological range, w...

Problems solved by technology

[0002] In the orchard made of natural grass, there will be many kinds of wild weeds, including broad-leaved grass, crabgrass, purslane, foxtail, etc. The weeds are of different heights, chaotic growth, many pests, and many weeds, for fruit trees The sunlight, temperature, moisture, etc. required for the normal growth of the orchard have varying degrees of influence, which is not conducive to the cultivation of high-quality fruit in the orchard. Therefore, it is proved to be natural to choose a grass that is conducive to the growth of fruit trees in the orchard to form a single turf. Development direction of grass-based orchard
