AI Technical Summary

Technical Problem

The prior art lacks composite fertilizers suitable for cigar tobacco growth, which leads to the intrinsic chemical composition and appearance indicators of cigar tobacco leaves that cannot be effectively met, especially when the ratio of nitrate nitrogen and ammonium nitrogen is unbalanced, which affects the internal chemical composition and appearance indicators of cigar tobacco.

Method used

Provide a nitrogen fertilizer for cigar tobacco, including nitrate nitrogen fertilizer and ammonium nitrogen fertilizer, with a molar ratio of (0.66-1.50): 1, combined with decomposed oil cake, phosphorus fertilizer and potassium fertilizer, to prepare it into cigar tobacco fertilizer, and balance the chemical composition of the cigar leaves by adjusting the nitrogen form ratio.

Benefits of technology

Improve the soil environment of the root area of the tobacco plant, promote root development, increase the number of effective leaves, improve the growth rate and quality of cigars, and meet the specific growth needs of cigars.

Abstract

The invention discloses a nitrogenous fertilizer for cigars, a fertilizer and application. A nitrogenous fertilizer for cigars comprises a nitrate nitrogenous fertilizer and an ammonium nitrogenous fertilizer, and the molar ratio of the nitrate nitrogenous fertilizer to the ammonium nitrogenous fertilizer is (0.66-1.50): 1. The nitrate nitrogen fertilizer is potassium nitrate and / or calcium nitrate, and the ammonium nitrogen fertilizer is ammonium bicarbonate. The molar ratio of the nitrate nitrogen fertilizer to the ammonium nitrogen fertilizer is 1: 1. The invention also provides a fertilizer for cigars. The fertilizer comprises any nitrogen fertilizer for cigars. The fertilizer comprises the following components in parts by weight: 20-60 parts of decomposed oil cake, 20-40 parts of nitrogen fertilizer, 10-30 parts of phosphate fertilizer and 30-60 parts of potash fertilizer. The thoroughly decomposed oil cake is a thoroughly decomposed sesame cake. The nitrogenous fertilizer can improve the soil environment of the tobacco plant root zone, is beneficial to increasing the content of acid phosphatase in the soil, promotes the root development of the tobacco plant, increases the number of effective leaves, and can balance chemical components in cigar leaves.
