1.冬季深耕可以改良土壤,果园在生长季节中,由于农事操作活动频繁,如喷药、修剪、中耕除草等,使土壤形成了板结层,土壤的通透性能大大降低,自我调节能力减弱。通过深翻,不仅可以打破板结层,增加土壤空隙,促进土壤的透光通风,而且深翻可促使土壤进一步熟化和土壤中有机质的分化,有效地提高土壤肥力。 果树蔬菜 1. Deep plowing in winter can improve the soil. During the growing season, due to frequent agricultural operations, such as spraying, pruning, cultivating and weeding, etc., the soil forms a caking layer and the permeability of the soil can be greatly reduced and the self-regulating ability weakened. Deep puffing can not only break the clump layer, increase soil voids and promote the light and ventilation of the soil, but deep puffing can promote the further ripening of the soil and the differentiation of organic matter in the soil, effectively improving the soil fertility.
