Embodiment 1

[0013] Intercropping of flue-cured tobacco variety K326 and Adenophora adenophorum. (1) Flue-cured tobacco planting: According to the GAP planting standards of flue-cured tobacco, land preparation, fertilization, ridge mulching, and transplanting are carried out. One row of flue-cured tobacco is planted in each ridge, the ridge width is 120cm, and the plant spacing is 50cm; (2) Adenophora adenophorum planting: adopts the "1+1" planting mode, that is, alternate planting of flue-cured tobacco and adenophora per ridge. Adenophora adenophorum is planted in one row per ridge with a ridge width of 40 cm. Sow in shallow furrows in early and mid-April. After emergence, thin the seedlings when there are 2-3 true leaves. The leaves of the seedlings are not overlapped. When the height of the seedlings is 12-15cm, the seedlings are fixed and the plant spacing is 10-15cm; (3) Cultivation management : According to the growth law of tobacco and Adenophora, timely and reasonable arrangement o...

Abstract

The invention discloses a method for interplanting Adenophora stricta in field to improve the quality of flue-cured tobacco. The method comprises the following steps of according to a GAP (good agricultural practice) farming standard of the flue-cured tobacco, leveling soil, performing conventional fertilization and ridging, and ensuring the line spacing of tobacco ridges is 120cm and the row spacing is 50cm; after the tobacco is transplanted, planting the Adenophora stricta in a '1+1' pattern, namely alternately planting the flue-cured tobacco and the Adenophora stricta; according to the growth laws of the tobacco and the Adenophora stricta, timely and reasonably arranging field management, irrigation, topdressing and integrated pest management. Tobacco leaves treated by the method have more coordinated inner components, smoke is milder and more fragrant, and the quality of the tobacco leaves is improved; meanwhile, the field planting method is simple, the management is simple, the operation is convenient and the method is easily promoted in a large area; the Adenophora stricta can be deeply processed, and the yield and the economic benefit of crops in a unit area of land are totally improved.

Description

Technical field [0001] The invention belongs to the technical field of flue-cured tobacco planting, and specifically relates to a planting method for interplanting and interplanting flue-cured tobacco with Adenophora adenophorum in the field to improve the quality of flue-cured tobacco. Background technique [0002] Interplanting and interplanting have a long history in our country and have made great contributions to both traditional and modern agriculture. Reasonable use of interplanting methods can effectively control pests and diseases, increase crop yield and quality, and reduce the application 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. Interplanting may have some unpredictable results, mainly because the root system of one of the plants in the interplanting will release alleloche...
