Nutriment for tobacco leaves, and prepartion method

Abstract

This invention relates to a fertilizer for improving tobacco leaves growth and quality, which is composed of: urea, potassium dihydrogen phosphate, potassium sulfate, zinc sulfate, ferrous sulfate, borax, manganese sulfate, ammonium molybdate and copper sulfate. The fertilizer can be used together with other organic fertilizers during seedling raising period, added to tobacco roots by infusion or sprayed onto tobacco leaves directly. The fertilizer has such advantages as low cost, easy production and wide applications in various tobacco growth periods. The fertilizer can improve freeze and drought resistance of tobacco leaves, promote the growth and quality of tobacco leaves, increase the yield of tobacco leaves, prevent elements excess or deficiency, prevent soil crusting or degradation, and protect water and soil.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a tobacco leaf nutrient used for planting tobacco and a preparation method thereof. Background technique [0002] In the cultivation of tobacco, the chemical fertilizers traditionally used for tobacco usually use nitrogen, phosphorus, potassium, etc., commonly known as large chemical fertilizers. The simple use of large chemical fertilizers leads to an imbalance in the nutritional structure. Although it can play a certain role in promoting the growth of tobacco leaves, it also causes many disadvantages to the continuous planting of tobacco leaves and the production of tobacco. One is the lack of a variety of medium and trace elements. It causes crop resistance, cold resistance, drought resistance and resistance to diseases and insect pests to be weak, and it is easy to cause various deficiency diseases of tobacco leaves and excessive poisoning of certain elements...

Problems solved by technology

The simple use of large chemical fertilizers leads to an imbalance in the nutritional structure. Although it can play a certain role in promoting the growth of tobacco leaves, it also causes many disadvantages to the continuous planting of tobacco leaves and the production of tobacco. One is the lack of a variety of medium and trace elements. It causes crop resistance, cold resistance, drought resistance and resistance to diseases and insect pests to be weak, and it is easy to cause various deficiency diseases of tobacco leaves and excessive poisoning of certain elements, which affects the growth of tobacco leaves and reduces the yield and quality of tobacco leaves; the second is the planted tobacco leaves. The yield is not easy to increase, the quality is poor, the nutrients are few, the bad ingredients exceed the standard, the chemical composition and the rating rate of the absorption index are low, and after baking and drying, they are mostly khaki, dull, less oily, and the planting benefits are poor, which leads to a On the one hand, there is a surplus of inferior tobacco leaves; on the other hand, the production and operation of most cigarette manufacturers are sluggish due to the lack of high-quality tobacco leaves; third, the long-term use of large chemical fertilizers is likely to cause soil degradation and compaction, especially the excessive application of nitrogen fertilizers, which is also prone to pollution of soil and groundwater sources , so the country clearly does not advocate the application of more nitrogen fertilizers; Fourth, the use of large chemical fertilizers requires a large amount of planting investment and poor economic benefits

In the existing technology, a plant growth regulator has been used, but the production process of the regulator is complicated, the cost is high, and it is difficult for tobacco farmers to accept it, so it is not conducive to popularization and use.
