Embodiment Construction

[0015] The present invention is described in detail below in conjunction with embodiment.

[0016] The specific operation is implemented according to the following steps:

[0017] 1. Farming and disinfection in the field

[0018] Tobacco seedlings are transplanted at equidistant fixed points, the row spacing is 1.2m×0.5m, and the density is 16800 plants / hm 2 . Dig furrows between the rows reserved for tobacco, the furrow width is 0.8m, the furrow depth is 0.2m, and a layer of lime powder is sprinkled on the bottom of the furrow for disinfection, with an amount of about 500g.m -2 .

[0019] 2. Preparation of Coprinus comatus mushroom blocks

[0020] (1) Bacteria block base material preparation. The matrix components are: wheat straw 80%±2%, wheat bran 8%±0.8%, cow dung 8%±0.8%, urea 1.5%±0.2%, gypsum 1%, lime 1.5%±0.2%, of which wheat straw, cow dung Collected locally, wheat bran, urea, gypsum and lime are purchased from the market. The base material treatment steps are:...

Abstract

Provided is a method for ecologically regulating and controlling continuous cropping obstacles of tobaccos by interplanting coprinus comatus in a tobacco field. A 'coprinus comatus-cellulase-soil organic matter-soil organism-soil urease' ecological chain is constructed. The method comprises the specific operating steps: (1) shaded soil under tobacco plants is used as a coprinus comatus cultivationbed; (2) the tobacco field is furrowed and disinfected; (3) coprinus comatus fungus blocks are prepared, wherein a coprinus comatus fungus block base material comprises wheat straw, wheat bran, cow dung, urea, gypsum and lime; after pretreatment, material stirring, pile-building fermentation, pile turning and material airing are carried out on the fungus block base material, coprinus comatus strains are sown according to 10% of the dry weight of the base material; (4) the coprinus comatus fungus blocks are put into the cultivation bed: (5) coprinus comatus fungus leftovers are directly ploughed into the soil after tobacco leaves are harvested. By adopting the method, the soil microenvironment of the tobacco field is fundamentally improved, phenolic acid type allelopathic auto-toxic substances in the rhizosphere soil of the tobaccos are continuously and stably digested, and ecological regulation and control of continuous cropping of the tobaccos are realized; the coprinus comatus cultivation leftovers are recycled, so that waste is turned into wealth, the coprinus comatus cultivation cost is reduced, the quality of flue-cured tobaccos is improved, and income of tobacco farmers is increased.

Description

technical field [0001] The invention relates to an ecological control method for eliminating tobacco continuous cropping obstacles, in particular to a method for ecologically regulating tobacco continuous cropping obstacles by interplanting edible fungi with tobacco. Background technique [0002] China is a big tobacco producing country, and the production and sales of tobacco leaves and cigarettes account for about 1 / 3 of the world's total. The development of the tobacco industry has driven many poor farmers out of poverty and the development of related industries, and at the same time provided high taxes for the country. The tobacco economy has become an important pillar of the Chinese economy. Due to the limited area of ​​qualified tobacco fields, the continuous cropping system of tobacco single species has been adopted in my country's tobacco areas for a long time. However, tobacco is a crop that should not be continuously cropped. It is generally believed that continuo...
