Tobacco fertilization method capable of conserving tobacco-planting soil

Abstract

The invention relates to a tobacco fertilization method capable of conserving tobacco-planting soil. The tobacco fertilization method is characterized by comprising the following steps: a, fertilizing base fertilizer; b, transplanting; c, further applying seedling fertilizer; d, further applying potash fertilizer; and e, carrying out field management measures. By adopting the tobacco fertilization method capable of conserving the tobacco-planting soil, the volume weight, overall porosity, capillary porosity and aeration porosity of the soil are reduced, so that the capillary moisture capacity and moisture content of the tobacco-planting soil are increased, the quantity of microbes in the soil is increased, the pathogenic bacteria of tobacco bacterial wilt are reduced, and the yield, output value, average price and high and medium tobacco rate of tobacco are obviously improved.

Description

technical field [0001] The invention relates to a tobacco fertilization method which can protect tobacco planting soil. Background technique [0002] Tobacco leaf is one of the main economic crops in mountainous areas. In order to reduce labor and cost, improve quality and increase efficiency, tobacco farmers one-sidedly pursue the economic benefits of tobacco planting, neglect the soil fertility conservation of tobacco planting soil, and only use chemical fertilizers in tobacco leaf production for a long time, resulting in Soil compaction, acidification, aggregate structure damage, poor tillability, lack or imbalance of nutrients in the soil, etc. The degraded soil environment is not conducive to the normal growth of tobacco plants, and at the same time leads to the aggravation of tobacco diseases, which are becoming more and more serious. The degradation of tobacco planting soil has become one of the bottleneck problems in the sustainable development of tobacco leaf produc...

Problems solved by technology

[0004] In order to protect the tobacco planting soil, improve the productivity of the tobacco planting soil, and improve the quality of tobacco leaves, the research on tobacco planting soil conservation technology has also made great progress, integrating many conservation methods, such as crop rotation, straw returning to the field, and green manure overturning. 1. Increasing the application of farmyard manure can effectively improve the soil aggregate structure, increase soil permeability and biodiversity, and gradually increase the soil pH. However, the amount of chemical fertilizers and inputs have not been reduced while using straw, green manure and farmyard manure. On the contrary, it increases the amount of labor, which leads to the tobacco farmers of the second method not accepting the promotion and application
