Problems solved by technology

[0005] The current treatment methods for double-cropping flue-cured tobacco are mainly to increase the amount of nitrogen fertilizer, deep loosening, and promote the development of flue-cured tobacco. Most of the effects are not obvious. Among them, increasing the amount of nitrogen fertilizer has the following shortcomings: (1) flue-cured tobacco is sensitive to nitrogen fertilizer, and sufficient nitrogen fertilizer supply is required in the early stage. However, when the tobacco leaves are flat-topped, the soil nitrogen supply is required to be significantly reduced or stopped. Due to the increase of nitrogen fertilizer, the nitrogen supply of the soil often increases when the tobacco leaves mature, which is contradictory to the nitrogen demand of flue-cured tobacco, which affects the field maturity

Embodiment 1

[0050] A special fertilizer for double cropping flue-cured tobacco of the present invention is prepared according to the following method, and the method flow chart is as follows: figure 1 Shown:

[0051] 1. Weighing raw materials: 500kg of waste after producing fungus (medium composition: 78% oak wood chips, 20% bran, 1% gypsum powder and 1% white sugar, water content is 65%), 300kg humic acid and 200kg humic acid colonize the soil.

[0052] 2. Raw material crushing: mechanically crush the waste after producing fungus, with a fineness of 1-2mm.

[0053] 3. Disinfection: Sterilize the pulverized waste with steam, cool at 95°C for 30 minutes.

[0054] 4. Extraction of humic acid: use 0.1M NaOH (sodium hydroxide) solution to extract humic acid according to the ratio of humic acid raw material: sodium hydroxide solution mass volume ratio = 1:10, and then use 1:1 hydrochloric acid to adjust Supernatant to pH=1.

[0055] 5. Treatment of waste after fungus production: mix the wa...

Abstract

The invention discloses a fertilizer special for continuous cropping flue-cured tobacco, and its preparation method and application. The fertilizer is prepared from 10-80% of waste from auricularia production, 10-30% of humic acid raw material, and 10-20% of humus soil. The fertilizer selects the natural material with a promotion effect on plant roots, extracts out components for promoting the development of roots, and is added with a certain matrix beneficial for plant growth, which can remarkably alleviate the obstacle problem of continuous cropping flue-cured tobacco. By applying the special fertilizer, obstacle of continuous cropping flue-cured tobacco can be solved or alleviated, the early development capacity of continuous cropping flue-cured tobacco can be improved, the yield and quality of continuous cropping flue-cured tobacco can be improved significantly, and the income of tobacco growers can be increased.

Description

technical field [0001] The invention relates to a fertilizer and its preparation method and application, in particular to a special fertilizer for double crop flue-cured tobacco, its preparation method and application. It belongs to the field of fertilizer production and processing. Background technique [0002] The flue-cured tobacco in foreign high-quality tobacco leaf production countries adopts the crop rotation system, and the crop rotation time is 3-4 years. Flue-cured tobacco crop rotation has the following advantages: (1) It can balance the supply of soil nutrients, which is conducive to the balance of nutrients in the tobacco leaves, and the quality of tobacco leaves is better; (2) It can effectively control diseases and reduce the risk of tobacco leaf production; (3) The tobacco plants are well developed, Appropriate output and high-quality tobacco leaves can be obtained, and the benefits are increased. However, due to the influence of land policy and land area i...
