Grass-growing method in cherry orchards

Abstract

The present invention discloses a grass-growing method in cherry orchards. The grass-growing method in cherry orchards comprises steps of seed selection, weed removal, paspalum notatum sowing, sowing,fertilizing and watering, mowing and renewal, and astragalus sinicus sowing. A compound fertilizer I and a compound fertilizer II containing nutrients and having fermentation functions are prepared,decomposition and utilization of metabolites of herbaceous plants are facilitated, the soil environment is further improved, the soil fertility is greatly improved, and the growth environment of cherries is improved. The compound fertilizer I and compound fertilizer II both containing triacontanol are applied in a process of growing grass in the orchards. The paspalum notatum and astragalus sinicus are cultured in stages, so that the soil is in a grass-growing phase for a long time, the ability of the cherry orchards to prevent drought and waterlogging is improved, the soil fertility of the cherry orchards are also unaffected, the ecological environment of the cherry orchards is enriched, a large number of parasites generate, the number of natural enemies of pests is increased, the spreadof the pests is restricted, and a relatively long-lasting ecosystem in the orchards is formed.

Description

technical field [0001] The invention belongs to the field of plant biotechnology, and in particular relates to a method for growing grass in a cherry orchard. Background technique [0002] The method of growing grass in the orchard is an advanced, practical and efficient soil management method. It has been implemented in Europe, America, Japan and other countries for many years, and its application is very common. Its main functions are: to improve the microclimate of the orchard: The existence of the underlying surface leads to an increase in the volumetric heat capacity of the soil, while at night the long-wave radiation decreases, the net energy expenditure at night in the grass-growing area is smaller than that in the clear-plow area, and the annual and daily temperature differences of the orchard soil are reduced, which is beneficial to the growth and development of the root system of fruit trees. The absorption and utilization of water and fertilizer. When the relativ...

Problems solved by technology

[0012] However, although growing grass in the orchard can improve the soil environment, long-term planting will also cause soil fertility to decline, and the root system of cherries is shallow, especially cherries are susceptible to drought, waterlogging and wind damage as the trees grow older.
