Improvement of fertile soil by Grass mulching in Orchard

One is to prevent or reduce soil erosion. After the recommendation, the structure of soil aggregates was improved, the aggregates with large particle size increased, and the "cohesion" of soil was enhanced.

The second is to improve soil and improve soil fertility. Growing grass in the orchard and burying it in the soil at the right time can increase soil organic matter, improve soil structure, increase soil nutrients, and create a nutrient-rich, loose and porous root layer environment for the growth of fruit trees.

The third is to promote the ecological balance of orchards. The population and number of predatory natural enemies such as ladybugs, lacewings, aphid flies and spiders and parasitic natural enemies such as parasitic wasps in grassy orchards increased, and the ability of using natural enemies to control the occurrence and rampancy of insect pests was significantly enhanced.

The fourth is to optimize the orchard microclimate. The orchard recommendation can reduce the diurnal and seasonal variation of soil temperature, which is beneficial to the root growth and nutrient absorption of fruit trees.

The fifth is to inhibit the growth of weeds. Red, white clover, Bahia grass, ryegrass and other strong competitiveness, after the formation of turf can effectively inhibit the growth of a variety of weeds, the inhibition rate is 55% and 70%. The sixth is to promote the development of tourism agriculture. With the development of tourism and leisure agriculture, Nongjiale is loved by the majority of consumers. When the fruit trees are in full bloom in spring, the grassy orchard is already green, adding a layer of beauty; when the fruit is full of branches, the orchard interplanting white clover is full of red and white flowers, like starry summer nights, which makes people relaxed and happy; even if the flowers are withered and the fruit is harvested, the grass orchard is still green, making the fruit industry sightseeing not weak in the off-season and more prosperous in the peak season.
