The orchards have many advantages in the fall of grass in the orchard: high fertility and long fertilizer efficiency. The amount of fertilizer released from fruit trees is generally 7%. The fertility of the orchard grazing can be equivalent to 2-3 times more than that of manure, and the fertilizer effect can last 2-3 years. Reduce water transpiration; inhibit weed growth; control soil erosion; reduce orchard pests and diseases to ensure high fruit yield, high quality and high efficiency. Orchard grazing method: Before the fall to frost, weeds are harvested in the orchard, and crop straw can also be used to grind and evenly spread between rows or fruit trees. The thickness is 10-15 cm and the grass covers 15-20 cm. Thick fertile soil, shoot flat can. China Agricultural Network Editor
