Abstract

The present invention provides a tobacco water and fertilizer integrated planting method suitable for the southeast tobacco area of ​​China, the method at least includes the following steps: (1) applying fertilizer to the tobacco planting field from March to April, and starting on the traces formed by the application of fertilizer strips; Ridge, described fertilizer comprises tobacco special fertilizer, organic fertilizer and potassium sulfate, and the application rate of described tobacco special fertilizer is nitrogen element 2.2~2.9kg / mu, phosphorus element 3.3~4.2kg / mu; Potassium element 5.6~7kg / mu mu; the application amount of the organic fertilizer is according to nitrogen element 1~2.4kg / mu; phosphorus element 0.8~1.6kg / mu; potassium element 0.2~1.6kg / mu; potassium sulfate 5~7.5kg / mu; (2) installation Water and fertilizer integrated equipment and laying of drip irrigation pipes; (3) 13-17 days, 26-30 days, 33-37 days, 40-44 days, 47-51 days and 54-58 days after tobacco transplantation in Longshang Potassium nitrate was applied using integrated water and fertilizer equipment. By adopting the method for planting tobacco, more than 30% of fertilizer consumption can be saved; especially the consumption of nitrogen fertilizer and potassium fertilizer.

Description

technical field [0001] The invention relates to an agricultural planting method, in particular to a tobacco water and fertilizer integrated planting method suitable for the southeast smoking areas of China. Background technique [0002] Tobacco, Nicotiana tabacum L., is one of the important economic crops in my country, with the planting area and output ranking first in the world. In the process of tobacco leaf production, fertilizers directly affect the growth and development of tobacco plants, the output value and quality of tobacco leaves. In recent years, excessive use of chemical fertilizers in tobacco production has been widespread. Taking the rice field tobacco area in southern Anhui, Anhui Province as an example, the amount of nitrogen fertilizer used is 7.5kg N / mu, and the amount of phosphorus fertilizer used is 7.0kg P 2 o 5 / Mu, the amount of potassium fertilizer is 20.0kg K 2 O / mu, the utilization rate of nitrogen, phosphorus and potassium fertilizers for toba...
