Abstract

The invention relates to a rice and tobacco alternate planting method, and belongs to the technical field of planting. The method comprises the steps of 1, rice planting, wherein seed selection, seedling raising, seedling transplanting and transplanted field management are performed, and harvesting is performed after rice is mature; 2, rice field management, wherein after rice is harvested, all harvested straw is subjected to mulching treatment; 3, tobacco planting, wherein after fertilization, tobacco is transplanted and planted; 4, tobacco management, wherein weeding, deinsectization, irrigation and fertilization are performed; 5, tobacco harvesting, wherein tobacco is harvested after being mature. According to the method, chemical fertilizer consumption in the tobacco planting process is greatly lowered, the soil properties are improved, the tobacco leaf yield is increased, the content of aroma substances in tobacco leaves is greatly increased, and the tobacco leaf quality is improved. Interplanting is performed on tobacco and soybeans or wheat, planting space and resources are sufficiently utilized to the maximum extent, element loss is avoided, it is ensured that elements arerecycled, circulation and balance of an ecological system are ensured, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a method for alternately planting rice and tobacco, belonging to the technical field of planting. Background technique [0002] Tobacco is one of the important economic crops in my country, and its planting area and total output both rank first in the world. At present, my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain high yields of tobacco leaves. However, the use of large amounts of chemical fertilizers and pesticides has caused serious damage to the soil and environment for tobacco planting, resulting in the emergence of high-quality tobacco areas in some long-term tobacco planting areas. The unbalanced enrichment and depletion of soil nutrients, the imbalance of soil nutrient supply, and the deterioration of farmland ecological environment lead to a significant decline in the quality of tobacco leaves and the benefits of tobacco planting, causing losses to toba...
