Embodiment Construction

[0017] 1. Preparation of seedlings and stems

[0018] Preparation of the stems of Pinellia chinensis: Before sowing, the stems of Pinellia chinensis must be sterilized. The method is as follows: the seed stems stored in a cool place in the previous year are sprayed and disinfected with 5% carbendazim solution, and then workers gently turn the seed stems to make the disinfectant fully contact with the seed stems. Pay attention when disinfecting: workers must wear gloves and do a good job of self-protection. The sterilized stems are tightly wrapped with plastic cloth and placed for about 12 hours. Then, they are moved to a place with sufficient sunlight and dried in the sun for 3-4 hours. The processing of the stems is completed.

[0019] The preparation of flue-cured tobacco seedling hardening is as follows: in the middle of February of that year, set up the greenhouse frame, fasten the greenhouse film, tighten and compact, and raise the temperature for standby; set up the han...

Abstract

The invention provides a flue-cured tobacco pinellia ternate interplanting method overcoming the allelopathic autotoxicity function. In the method, influences of crop rotation on the planting industry are avoided by means of interplanting of pinellia ternate and flue-cured tobacco. The method specifically includes the steps that pinellia tenata (Thum b.) Breit and the flue-cured tobacco are planted in the field in an open mode, according to the specific planting mode, one part is used for planting flue-cured tobacco, one part is used for planting pinellia tenata (Thum b.) Breit, and the flue-cured tobacco and pinellia tenata (Thum b.) Breit are planted at an interval; in the second year, pinellia ternate and the flue-cured tobacco are planted with the positions being exchanged. The interplanting scheme overcomes continuous cropping obstacles of flue-cured tobacco and pinellia ternate. Besides, the flue-cured tobacco in the interplanting method is adopted and can achieve the shading, cooling and moisture retention functions, field microclimate can be remarkably improved, the sprout tumbling phenomenon of pinellia ternate in summer can be overcome, vigorous growth of pinellia ternate in summer is guaranteed, and the yield of pinellia ternate is increased.

Description

technical field [0001] The invention provides a crop interplanting scheme, and more specifically relates to a flue-cured tobacco pinellia interplanting method for overcoming allelopathic autotoxicity. technical background [0002] With the development of modern science and technology and the improvement of flue-cured tobacco curing technology, people pay more and more attention to the influence of tobacco agricultural production on the yield and quality of flue-cured tobacco. Constrained by factors such as limited arable land, economic interests, and planting conditions, flue-cured tobacco production has a single farming system, making continuous cropping obstacles (Continuous crop-ping obstacles) a prominent problem in tobacco agricultural production. How to solve the problem of continuous cropping obstacles in the process of tobacco agricultural production, effectively maintain the basic productivity of the country's tobacco fields, consolidate the achievements of modern t...
