Four points of winter fruit scraping

First, scraping objects pears, peaches, plums, grapes, chestnuts, walnuts, apples, plums and other fruit trees are prone to produce rough skin, adult trees more than 10 years old, are necessary to scrape. Scrape the rough bark and cracks on the stems and stems of the tree, and scrape the lesions such as rot and ring disease.

Second, scraping skin scraping time should be carried out in the early winter and early spring, that is, temperatures began to rise, pests and germs have not yet started when activities. Do not scrape the skin prematurely, otherwise the tree nutrients will be lost and the fruit trees will be safely overwintered. The skin is shaved once every 2 to 3 years.

Third, scraping deep skin scraping can only scrape off the trunk and the main branch completely corked rough skin, split skin and cut edge and branch residue at the skin, the depth to not see white is appropriate, to avoid damage within Cortex. The thick skin of the pear tree can be properly shaved, and fruit trees such as peaches and apricots must be lightly shaved. For those with stronger tree vigor, you can scratch more, and those with weaker vigor should shave more.

Fourth, scrape the white skin after the application of whitening paint again to kill pests and bacteria, while reducing the incidence of sunburn. The formulation of the whitening agent is water: quicklime: lime sulfur stock solution: salt: fat is 40:10:2:2:0.3. First open the lime, pour the oil, add water into the lime milk, then add the lime sulfur and salt.
