Special water-fertilizer integrated fertilizer for tobacco leaves and application method of special water-fertilizer integrated fertilizer

Abstract

The invention aims to provide a special water-fertilizer integrated fertilizer for tobacco leaves and an application method of the special water-fertilizer integrated fertilizer, solves the problems of poor pertinency and unobvious fertilizer-saving, water-saving, yield and revenue increasing effects of an existing water-fertilizer integrated fertilizer for tobacco leaves. In order to achieve theaim, the invention adopts the technical scheme that the special water-fertilizer integrated fertilizer for tobacco leaves comprises a special fertilizer for a seedling stage, a special fertilizer fora vigorous growing stage, a special fertilizer for a maturation stage and a special fertilizer for a harvesting stage. Drip irrigation fertilizer application adopted by the invention is a precise fertilizer application method, and the fertilizer is only applied to roots, so that the utilization ratio of the fertilizer is remarkably increased, and the use amount of the fertilizer can be reduced by30-50% or above as comparison with that of the fertilizer used by using a conventional fertilizer application method; and root layers are only moistened by using drip irrigation fertilizer application, no water and fertilizers are supplied among rows, and therefore, the growth of weeds can also be remarkably reduced. Due to the coordinated action of water and the fertilizer, the consumption of water can be remarkably reduced. In addition, due to the water-saving effect of facility irrigation, the water is saved by 50% or above. A pesticide can be dripped in drip irrigation so as to play a relatively good role in preventing and controlling soil pests, threadworms and root diseases.
