Abstract

The invention discloses a special foliar spray fertilizer for planting of a selenium-rich tobacco, which belongs to the technical field of tobacco production. A technical scheme of the invention is as follows: the special foliar spray fertilizer for planting of the selenium-rich tobacco comprises, by weight, 0.53 to 1.42% of sodium selenite, 17.01 to 33.03% of borax, 22.45 to 41.43% of zinc sulfate, 23.12 to 41.70% of manganese sulfate and 3.21 to 9.91% of sodium molybdate; before use of the fertilizer, the above-mentioned components are mixed in proportion and water is added so as to prepare a spray. The fertilizer is uniformly sprayed on the front and the back of tobacco leaves in rain-free weather 4 to 7 days before maturity and harvest of lower leaves of the tobacco, and spraying amount is 48 to 52 kg / Mu. The invention has the following advantages: the special foliar spray fertilizer provided by the invention can increase selenium content in the tobacco leaves, improve the commercial grade and industrial availability of the tobacco leaves and greatly enhance inherent quality of a selenium-rich tobacco leaf and safety of raw tobacco leaves at the same time, thereby ensuring sustainable development of production of the high-quality selenium-rich tobacco leaf.

Description

technical field

[0001] The invention belongs to the technical field of tobacco production, and in particular relates to a special foliar spray fertilizer required for planting selenium-enriched tobacco. Background technique

[0002] In the prior art, selenium is one of the trace elements necessary for the human body. Selenium has certain preventive and therapeutic effects on Keshan disease, Kaschin-Beck disease, tumors, respiratory diseases, and low fertility. In 2000, the recommended dietary selenium intake (RNI) for residents was set at 50ug / d in China, but the selenium content absorbed by the human body from ordinary food and water is far from enough. As a cigarette consumer, smoking selenium-enriched cigarettes also absorbs the selenium content. one of the ways. Many studies have shown that the successful development of selenium-enriched tobacco leaves for low-hazard cigarettes can increase the selenium content of cigarettes, reduce the tar and free radical content, imp...
