[0025] 2. Preparation of fertilizer preparations

[0026] S1, ingredients: use an electronic scale to carry out proportioning and weighing according to the above formula;

[0027] S2, pulverization: the rapeseed cake is pulverized into powder with a pulverizer;

[0028] S3, mixing: mix rapeseed cake (powder), distiller's grains and vermicompost, then add citric acid, expanded perlite and Bacillus amyloliquefaciens, and stir evenly;

[0029] S4. Storage: Pack the mixture into bags and store in a cool and ventilated place.

[0030] The present invention mixes ingredients such as rapeseed cake, distiller's grains, and vermicompost in a certain proportion as the base fertilizer for continuous cropping tobacco fields. It does not require complex and time-consuming fertilizer production processes such as fermentation and retting, avoids the loss of nutrient elements, and can realize continuous cropping The rapid and effective improvement and restoration of tobacco field soil meets...

Embodiment 1

[0033] The fertilizer preparation adopted in this implementation has the following components by weight: 43 parts of rapeseed cake, 17.4 parts of distiller's grains, 52 parts of vermicompost, 3.1 parts of citric acid, 52 parts of expanded perlite, and 0.35 part of Bacillus amyloliquefaciens.

[0034]The experiment was carried out in the field, using Yunyan 99 as the test material, and the tobacco seedlings were transplanted for daily management (Liu Guoshun. Tobacco Cultivation. China Agricultural Press, 2003; Han Jinfeng. Tobacco Cultivation Physiology. China Agricultural Press, 2003). Experimental group T1: The mixture of rapeseed cake, distiller's grains and vermicompost contained in the fertilizer preparation was applied to the soil as a base fertilizer, and the fertilization rate was 110-120kg / mu according to the fertilizer preparation. Experimental group T2: The fertilizer preparation was used as the base fertilizer, and it was applied to the soil by ditching and strip ap...

Embodiment 2

[0065] The fertilizer preparation used in this embodiment has the following components by weight: 44 parts of rapeseed cake, 17.2 parts of distiller's grains, 51.6 parts of vermicompost, 3.1 parts of citric acid, 52 parts of expanded perlite, and 0.35 parts of Bacillus amyloliquefaciens.

[0066] The experiment was carried out in the field, using Yunyan 99 as the test material, and the tobacco seedlings were transplanted for daily management (Liu Guoshun. Tobacco Cultivation.

Abstract

The invention discloses a fertilizer preparation for improving and restoring continuous cropping tobacco field soil and an use method thereof. The fertilizer preparation is prepared from the followingcomponents in parts by weight: 43 to 44 parts of rape seed cake, 17.2 to 17.6 parts of vinasse, 51.6 to 52.8 parts of wormcast, 3.0 to 3.2 parts of citric acid, 50 to 53 parts of perlite and 0.3 to 0.4 part of bacillus amyloliquefaciens. The fertilizer preparation is used as base fertilizer, so that the tobacco field soil volume weight is reduced; the contents of rapid available nitrogen, rapid available phosphorus and rapid available potassium are increased; the flue-cured tobacco agricultural property is improved; the chemical ingredient cooperated effect is improved; the yield, the production value and the first-class tobacco proportion is obviously increased; the economic benefits are obviously improved.

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco planting, and in particular relates to a fertilizer and a method for improving soil physical and chemical characteristics of continuous cropping tobacco fields, increasing tobacco yield and coordinating internal chemical components. Background technique [0002] Flue-cured tobacco (Nicotiana tabacum L.) is an important economic crop. The growth, development, yield and quality of flue-cured tobacco are closely related to the physical and chemical properties and fertility level of the soil. Suitable soil conditions are an important basis for the formation of high-quality and suitable tobacco leaves. Soil bulk density can effectively reflect the physical properties of soil and indicate soil quality and productivity. Excessive soil bulk density will inhibit plant root growth and mineral nutrient absorption, thereby reducing plant photosynthetic rate or aboveground productivity. Appropriate soil bulk ...
