近几年的连续干旱,给农作物造成了严重的危害,由于70%以上的果园都建立在丘陵山地上,几乎没有水浇条件,果树受害程度更为严重。现介绍几项果树抗旱栽培新技术。一、果园覆盖1.薄膜覆盖。一般在春季干旱、风大的3~4月份进行,覆盖时可顺行覆盖或只在树盘下覆盖。树下覆膜能减少水分蒸发,提高根际土壤含水量;盆状覆膜具有良好的蓄水作用;覆膜提高土壤温度,有利于春季根系生理活性的提
In recent years, successive droughts have caused serious damage to crops. As more than 70% of the orchards are built on hills and hills, there is almost no watering conditions and the degree of damage to the fruit trees is even more serious. Now introduce several new techniques of drought-resistant fruit trees. First, the orchard cover 1. Film coverage. Generally in the spring drought, the wind from March to April, coverage can be covered in parallel or only covered under the tree. Film under the tree can reduce the evaporation of water and increase rhizosphere soil water content; basin-shaped film has a good water storage effect; film to improve soil temperature is conducive to spring root physiological activity
