近年来,由于果树生长结构的变化,李的种植面积发展很快,但许多地方,对李树任其放任生长,不加整形,只在结果后进行疏除各级过密枝,这样常造成李树无形、产量低、质量差,至使经济寿命缩短,因此,应重视李树的整形修剪。 一、整形。李树较喜光,应以开心形为好。整形从定于开始,定植后于春季进行定干,即在距地面50—60厘米饱满芽处短截,整形带内可以产以4—5个新枝;冬剪时,选留分布均匀的主
In recent years, due to changes in the growth structure of fruit trees, Li’s planted area has developed rapidly, but in many places, Li Shusheng let it grow, without shaping, only after the results of thinning at all levels of dense branches, which often results in Li Shu Invisible, low yield, poor quality, to shorten the economic life expectancy, therefore, should pay attention to Li Shu’s plastic trim. First, plastic surgery. Li Shu more light, should be happy as well. Plastic set from the beginning, set in the spring after planting fixed dry, that is, 50-60 cm from the ground full bud short cut, plastic belts can produce 4-5 new branches; winter shear, choose to distribute the main
