Tobacco ridge surface fertilizing method

Abstract

The invention relates to a tobacco ridge surface fertilizing method, comprising the steps of ridging, including the steps of ditching, applying base fertilizer, carrying out soil preparation and ridging in the field 15-30 days before tobaccos are transplanted; applying ridge surface fertilizer, namely spreading fertilizer specially used for the tobacco at the top of a ridge body when soil moisture content is appropriate after ridging; laminating, including the steps of immediately covering a mulching film after the ridge surface fertilizer is applied on tobacco ridges, pressing a small amount of soil at the edges of the mulching film at the two sides and the two ends of each tobacco ridge after the mulching film is covered and compacting the mulching film; and transplanting, including the steps of firstly excavating a transplantation hole, then pouring root setting water, spraying or pouring pesticide, placing tobacco seedlings in the middle of the transplantation hole and covering soil. By adopting the tobacco ridge surface fertilizing method provided by the invention, tobacco seedlings can quickly absorb fertilizer, application of weed killer is reduced, investment cost of a tobacco grower is reduced, and tobacco growing benefit is increased.

Description

technical field [0001] The invention relates to a tobacco planting fertilization method, in particular to a tobacco ridge surface fertilization method. Background technique [0002] At present, in tobacco cultivation, the fertilization of tobacco includes base fertilizer and top dressing. The base fertilizer is applied in ditches in the field, then ridges are formed, and when the soil moisture is suitable, plastic film is covered, and transplanting pits are dug, and the tobacco seedlings are inserted into the pits, and finally Water, cover the soil, and complete the transplanting. The topdressing fertilizer is generally 30 days before transplanting and topdressing fertilizer is applied in the hole next to the tobacco plant. When transplanting, the root system of tobacco seedlings is generally thin and weak, and the ability to absorb fertilizer is poor. The root system of ordinary transplanted tobacco seedlings cannot fully contact with the fertilizer of the laid soil base f...

AI Technical Summary

Problems solved by technology

When transplanting, the root system of tobacco seedlings is generally thin and weak, and the ability to absorb fertilizer is poor. The root system of ordinary transplanted tobacco seedlings cannot fully contact with the fertilizer of the laid soil base fertilizer, resulting in a long time for seedlings to return and uneven growth of tobacco plants.

The practice of applying nest fee when transplanting, because the fertilizer concentration is too high and too close to the root system, it is easy to cause fertilizer damage, which will lead to slow growth or death of tobacco plants in severe cases

Spray herbicides on the ridges before covering the plastic film to control weeds, but if the chemical herbicides are used improperly, they will easily cause phytotoxicity
