How does orchard grass cover improve and fertilize the soil?

First, it prevents or reduces soil erosion and water loss. After planting grass, the soil's aggregate structure improves, the proportion of large-diameter aggregates increases, and the soil's "cohesion" is strengthened.

Second, it improves the soil and raises soil fertility. Planting grass in the orchard and turning it into the soil at the right time can increase soil organic matter, improve soil structure, and increase soil nutrients, creating a nutrient-rich, loose and porous root-layer environment for the growth of fruit tree roots.

Third, it promotes the ecological balance of the orchard. In grass-covered orchards, populations and numbers of predatory natural enemies such as ladybugs, lacewings, hoverflies and spiders, as well as parasitic natural enemies such as parasitic wasps, increase, and the ability to use natural enemies to control the occurrence and outbreak of insect pests is markedly enhanced.

Fourth, it optimizes the orchard microclimate. Planting grass in the orchard can reduce the range of diurnal and seasonal changes in soil temperature, which is beneficial to the growth of fruit tree roots and their absorption of nutrients.

Fifth, it suppresses weed growth. Red clover, white clover, bahia grass, ryegrass and others are highly competitive, and once they form a turf they can effectively suppress the growth of many weeds, with a suppression rate of 55%-70%. Sixth, it promotes the development of agritourism. With the development of leisure and sightseeing agriculture, farmhouse entertainment is deeply loved by consumers. In spring, when the fruit trees are in full bloom, the grass-covered orchard is already a stretch of fresh green, adding a layer of beautiful scenery; when the branches are heavy with fruit, an orchard interplanted with white clover is covered with red and white flowers all over the ground, like stars dotting a summer night, making people feel relaxed and joyful; even after the flowers have faded and the fruit has been harvested, the grass-covered orchard is still a expanse of green, making orchard sightseeing not dull in the off-season and even more thriving in the peak season.
