实践证明,对梨树正确运用疏果技术,适当控制座果数量,做到合理留果,对夺取当年优质高产,促进来年稳产丰产,提高经济效益都极为重要。梨树疏果高产法的技术要求是: 1、疏果的最佳时期以早疏为好,一般分两次进行。第一次在落花后15—20天内完成,主要疏去果形不正的畸形果、过小果和过密处的小果。第二次疏果在第一次疏果后的15—20天进行,主要是选留优果,疏去劣果,按适量标准确定留果量。整个疏果过程要在座果后40天完成。2、疏果的适量标准应按品种、树势及其它管理 Practice has proved that pear proper use of fruit thinning technology, the appropriate control of the number of fruit, so as to achieve a reasonable retention of fruit, to seize high quality and high yield that year, to promote a stable yield in the coming year, improve economic efficiency are extremely important. Pear tree thinning high yield method of the technical requirements are: 1, the best period of thinning as early as sparse as well, generally divided into two. The first time in 15-20 days after the completion of the flower, the main dredging fruit malformed abnormal fruit, too small fruit and over-small fruit. The second fruit thinning in the first 15-40 days after thinning fruit, mainly to retain excellent fruit, sparse to bad fruit, according to the appropriate standard to determine the amount of fruit retention. The entire fruit thinning process to be completed 40 days after the fruit. 2, the amount of standard thinning should be species, tree and other management
