用扦插苗培育的葡萄,在一般管理情况下,结五六年果后,根部就开始老化,枝叶和果实逐年变小,产量和质量也随之逐渐下降。要解决此问题,除了采取合理修剪和加强肥水管理等措施外,最好的办法是采取多根靠砧嫁接,使结果株不断增加大量新根,保证养分供给,得以从根本上恢复树势。其基
With the cultivation of cutting seedlings of grapes, under the general management situation, after five or six years of fruiting, the roots began to age, leaves and fruits year by year smaller, the yield and quality will also gradually decline. In order to solve this problem, in addition to measures such as pruned manure and water and fertilizer management, the best way is to adopt multiple rootstock grafting so as to continuously increase a large number of new roots and ensure the supply of nutrients so that the situation can be fundamentally restored.
