Abstract
The invention relates to the technical field of medical fertilizers, in particular to a novel fertilizer special for eucalyptus and a preparation method thereof. The novel fertilizer special for eucalyptus comprises the following components in percentage by weight: 1.5-10% of a bactericidal composition, 20-60% of a water-soluble fertilizer, 3-5% of a dispersing agent, 1-4% of a wetting agent and the balance of filler, wherein the effective components of the bactericidal composition are formed by compounding farnesol and mandipropamid or pyraoxystrobin. The novel special fertilizer for the eucalyptus contains fertilizer components and pesticide components, can provide nutrients required by growth of eucalyptus seedlings after one-time fertilization, can effectively prevent and treat gray mold of the eucalyptus seedlings, can improve the survival rate of eucalyptus seedling cultivation, and is beneficial to the progress of eucalyptus seedling cultivation work.
Description
technical field [0001] The invention relates to the technical field of medicinal fertilizers, in particular to a novel special fertilizer for eucalyptus and a preparation method thereof. Background technique [0002] In agricultural production, fertilizers can provide nutrients for crop growth; pesticides can prevent crop diseases and insect pests; fertilizers and pesticides are mixed to make medicinal fertilizers, which can provide nutrients for crop growth and prevent crop diseases and insect pests in one application. [0003] During the cultivation process of eucalyptus seedlings, they will be attacked by diseases and insect pests. The pests and diseases that endanger the growth of eucalyptus seedlings include leaf spot, bacterial wilt, anthracnose, gray mold, long-beetle and aphids, among which gray mold is a common disease of eucalyptus seedlings in South China, which can lead to tender stems, twigs and The leaves are rotten and necrotic or the whole plant dies, and th...
