Abstract

The invention discloses a special-purpose seedling-raising controlled-release fertilizer for a tobacco seedling-raising plate and a preparation method of the fertilizer, belongs to the technical field of pesticides and solves problem that the existing fertilizer is low in utilization rate and cannot prevent tobacco diseases and insect pests. A weight ratio of N to P to K in a film-coating controlled-release fertilizer is (15-20):(4-10):(6-15); the film-coating controlled-release fertilizer is further added with 0.1%-0.5% of fungicide, wherein the fungicide is prepared from the following materials: tobacco, black false hellebore, garlic, pyrethrum, ailanthus, mandala, uniflower swisscentaury root and weeping willow. The controlled-release fertilizer disclosed by the invention has a long release period, realizes satisfying demands of crops on nutrients such as nitrogen, phosphor, potassium, calcium, sulfur and the like, in the whole growth period by single-dose application. Meanwhile, an occurrence rate of diseases such as tobacco bacterial wilt, black shank and root rot, is greatly reduced, infection of germs in a seedling-raising period is avoided, and occurrence of diseases of stalks which are transplanted in a large field is greatly reduced. And meanwhile, the fertilizer is prevented from adding for many times, and labor cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco fertilizers, in particular to a special controlled-release fertilizer for growing tobacco seedlings in trays and a preparation method thereof. Background technique [0002] Tobacco is an important economic crop in our country. Since the tobacco monopoly system was implemented in our country in 1982, the tobacco industry has made great progress and has become an important pillar industry in the national economy. Tobacco cultivation is inseparable from special fertilizers, and tobacco seedling production is inseparable from special fertilizers. Moreover, there are many types of fertilizers. Generally speaking, the types of fertilizers commonly used in tobacco are usually divided into organic fertilizers, inorganic fertilizers, and biological fertilizers. Most organic fertilizers refer to any animal excrement and other fertilizers, such as human excrement, livestock excrement, poultry excrement and p...
