农桑14号栽培技术研究

通过十多年的跟踪调查，发现农桑14号在生产中易受早春晚霜为害、黄落叶较多、难以养成良好树形、易受天牛为害和易发流胶病等缺陷。通过研究，提出了选择适宜的立地条件和种植密度、搭配种植中晚生桑品种、采用第二年春伐和第三年春伐并夏伐定拳的树形养成技术、冻害后的肥培管理措施及天牛和桑流胶病的防治方法。

Study on Cultivation Technology of Mulberry Variety Nongsang 14

According to the ten years＂ follow-up survey, many defects of mulberry variety Nongsang 14 in production has been found, such as vulnerable in spring frost, too much yellow defoliation, difficulty in cultivating tree form, susceptible to longicorn and gummosis. Meanwhile, a series of measures has been proposed to solve the aboved defects, such as selecting appropriate site conditions and planting density,collocating medium and late budding mulberry varieties, cultivating the tree-form through spring cutting in the second year, spring and summer cutting in the third year, implementing the fertilizer application management measures after freezing, as well as adopting methods for prevention and cure of longicorn and gummosis.
