How to evaluate artificial grass and natural grass in orchard

At present, there are three development trends of orchard soil management standards with grass planting technology as the main content in China: natural grass planting system, artificial grass planting system and grass covering system. Straw mulching system is to cover all or part of plants, such as crop straw, dead grass and wheat coat, in the inter-row and inter-plant areas of orchard. Soil can be cultivated for a long time, which can improve soil fertility and keep soil moisture. Natural grass planting system is to let it grow naturally between rows and trees in the orchard, cover it with living grass layer, then eradicate vicious grass (grass with upright growth and woody stems, such as ash strips), artificially adjust the amount and height of grass to control the growth of trees, and the soil will not be plowed all the year round. However, the artificial grass planting system is a leisure area between rows of orchards. Artificial cultivation is suitable for local grass species. After years of cultivation and ploughing, underground grass and underground roots are rotten and fertile fields, which integrates orchard fertilization and biological mulching, improves the growth environment of trees, improves fruit quality and induces the development and utilization of grass resources. It is labor-saving, money-saving and simple. Fruit trees are perennial and efficient cash crops, which determines the intention of giving priority to helping fruit trees achieve high quality, high yield and high efficiency for a long time when selecting and implementing orchard soil management standards. Through comparative analysis, the following conclusions are drawn: the grass-growing system is better than the grass-covering system. Because it takes a lot of labor to collect and transport mulch to the orchard, and then cover it line by line or tree by tree, and when the rainfall is heavy in autumn, the mulch can't absorb the remaining water, so it is difficult to transpiration water and the underground humidity is high, which constitutes the growth of autumn shoots; The grass orchard adapts to local conditions, which relatively reduces labor input. In terms of planting grass, artificial planting grass system and natural planting grass system have their own advantages and disadvantages.
