随着果树品种更新换代的加速,越来越多老劣果园在选择进行更新过程中,经常会出现苗木成活率低、生长不良;进入结果期后结果少、产量低、果实品质差,树体抗性低、树势早衰、寿命短等问题,从而导致经济效益极低,这称之为果树重茬病。为解决苹果基地重茬问题,在选择对重茬病进行了多年的试验示范工作中发现,采用美国NEB平衡配方施肥的方法,是解决重茬病的克星。
With the acceleration of the replacement and renewal of fruit trees, more and more old and inferior orchards often have low survival rate and poor growth during the process of choosing to carry out the renewal. When entering the fruiting period, the results are less, the yield is low, the fruit quality is poor, Low resistance, premature aging tree, short life and other issues, resulting in very low economic benefits, which is called fruit stubble disease. In order to solve the problem of stubble crop in apple base, we found that using NEB balance formula fertilizing method in the United States to solve the problem of stubble in stubble disease,
