Method for improving flue-cured tobacco quality by interplanting radix ophiopogonis in field

Abstract

The invention discloses a method for improving the flue-cured tobacco quality by interplanting radix ophiopogonis in field. According to the flue-cured tobacco GAP planting standard, general fertilization and ridging are carried out after the land is flattened, the tobacco ridge row distance is 120cm, and the planting distance is 50cm. After the tobacco is transplanted, the radix ophiopogonis is transplanted between flue-cured tobacco rows in a '1+1' planting mode, and the planting distance of the radix ophiopogonis is 6-9cm. According to the growth rhythms of tobacco and radix ophiopogonis, field management, irrigation and additional fertilization are reasonably carried out in time, and the diseases and insect pests are comprehensively prevented. The inner contents of tobacco processed by the method are more coordinated, the tobacco taste is softer and more fragrant, and the tobacco quality is improved. Meanwhile, the field planting method is simple, easy to manage, convenient to operate and easy to popularize in large scale. The radix ophiopogonis can be further processed, so that the crop yield and the economical benefits of unit area land can be improved totally.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco planting, and in particular relates to a planting method for interplanting flue-cured tobacco and Ophiopogon japonicus in the field to improve the quality of flue-cured tobacco. Background technique [0002] Intercropping and intercropping have a long history in my country and have made great contributions to both traditional and modern agriculture. Rational use of intercropping can effectively control pests and diseases, improve crop yield and quality, and reduce the use of pesticides and fertilizers. The mechanism of its beneficial effect on crops is to change the distribution of nitrogen in the field, change the photosynthesis of plants, change the wind speed in the field, and prevent pests and diseases. There may be some unexpected results in interplanting, mainly because the root system of one of the interplanting plants will release allelochemicals to the surrounding soil environ...
