Precise tobacco fertilizing method under large-scale planting condition

Abstract

The invention discloses a precise tobacco fertilizing method under a large-scale planting condition. The method is characterized in that base fertilizer and fertilizer for top dressing are applied ina classified manner, 85-90% of nitrogen application rate is used as the base fertilizer, 10-15% of the nitrogen application rate is used as the fertilizer for top dressing, the base fertilizer is applied to furrows during furrowing through a method including comprehensive quantification, field measuring and label insertion, uniform mixing, equal-quantity packing, delivery according to fields and application by specially-assigned people, and the top dressing is performed by using a watering machine during transplanting and 25-30 days after transplanting. The method has the advantages that the method is scientific and practical, simple and convenient to operate and high in operability, and the method is accumulatively popularized in more than 0.6 million mu of tobacco fields in the southerntobacco growing areas of Anhui; the method is accurate and uniform in fertilizing, capable of increasing medium-tobacco proportion, tobacco growth vigor consistency and tobacco quality level, capableof increasing the tobacco planting benefits of large-scale farmers, capable of effectively satisfying the requirements of cigarette industry enterprises and capable of promoting the high-quality development of the tobacco growing areas.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco planting, in particular to a method for precise fertilization of flue-cured tobacco under large-scale planting conditions. Background technique [0002] With the steady advancement of large-scale planting of flue-cured tobacco, the average planting scale per household is getting larger and larger. In 2019, the average planting scale per household in the southern Anhui tobacco area has reached 80 mu. Flue-cured tobacco is an economic crop mainly harvested from leaves. Fertilization technology, especially the accuracy and uniformity of fertilization, is the key technology that affects the yield and quality of tobacco leaves. Excessive fertilization will lead to green and late maturity of tobacco leaves, and too small will lead to premature aging of tobacco leaves. Unevenness leads to inconsistent growth, which is not convenient for tobacco leaf harvesting, baking and field management, whi...
