Abstract

The invention relates to a method for paddy-upland rotation cropping of tobacco and rice and in-situ restoration of mineral nutrition. The method comprises the following process: tobacco planting: transplanting tobacco after fertilization; tobacco management: carrying out weeding, disinsection, irrigation and fertilization; tobacco harvesting: harvesting tobacco after the tobacco is matured; tobacco field management: subjecting harvested tobacco straw to harmless treatment, and covering a field with all treated straw so as to realize in-situ restoration of mineral nutrition; rice planting: transplanting rice seedlings, carrying out management for the field after transplanting, and carrying out harvesting after the rice is matured; and paddy field management: covering the paddy field with all harvested rice straw so as to realize in-situ restoration of mineral nutrition. The method provided by the invention has the following advantages: rice straw and husks are used as fertilizers and completely used for tobacco planting, or the tobacco straw is used as a fertilizer and completely used for rice planting, so the loss of elements can be effectively prevented; reutilization of the elements and circulation and balance of an ecological system are guaranteed; the environment can be easily protected; and application of a chemical fertilizer can be reduced.

Description

technical field [0001] The invention relates to a method for in-situ restoration of tobacco and rice paddy and dry crops and mineral nutrition, and belongs to the technical field of green ecological restoration. 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 l...
