Embodiment 1

[0018] A temperature-increasing and root-promoting agent for growing tobacco, which is made from the following raw materials: 50g of oil sour, 5g of starter, 5g of quicklime and 6g of rice husk biochar. Rice husk biochar is specifically the Manyuan brand.

[0019] When the tobacco seedlings are transplanted, the above-mentioned quicklime, biochar and oil are first buried at the bottom and surroundings of the tobacco seedling roots, and after the transplanting is completed, 5 g of liquid starter is sprayed on the tobacco seedling roots and surroundings. Above-mentioned consumption is the temperature-increasing and root-promoting agent consumption of 1 tobacco seedling.

Embodiment 2

[0021] A temperature-increasing and root-promoting agent for growing tobacco is made from the following raw materials: 60g of oil sour, 12g of starter, 7g of quicklime and 10g of rice husk biochar.

[0022] A temperature-increasing and root-promoting agent for growing tobacco and a method of use thereof, according to the following scheme:

[0023] When transplanting tobacco seedlings, firstly mix quicklime, biochar and oil sour evenly, and then bury them at the bottom and surroundings of the tobacco seedling roots. After transplanting, spray 12g of liquid starter on the roots and surroundings of the tobacco seedlings. Above-mentioned consumption is the temperature-increasing and root-promoting agent consumption of 1 tobacco seedling.

Embodiment 3

[0025] A temperature-increasing and root-promoting agent for growing tobacco and a method of use thereof, according to the following scheme:

[0026] A temperature-increasing and root-promoting agent for tobacco growth, which is made from the following raw materials: 80g of oil sour, 35g of starter, 8g of quicklime and 12g of rice husk biochar.

[0027] When transplanting tobacco seedlings, firstly mix quicklime, biochar and oil sour evenly, and then bury them at the bottom and surroundings of the tobacco seedling root system. After transplanting, spray 35g of liquid starter on the tobacco seedling roots and surrounding areas. Above-mentioned consumption is the temperature-increasing and root-promoting agent consumption of 1 tobacco seedling.

Abstract

A preparation method for a temperature-increasing root-promoting agent for tobacco growth, characterized in that: the temperature-increasing root-promoting agent is made of the following raw materials: 50%-80% of oil, 5%-35% of starter , 5%-8% quicklime and 6%-12% rice husk biochar. The temperature-increasing and root-promoting agent prepared by the invention makes the temperature of tobacco seedlings grow rapidly after transplanting to the temperature required to promote the growth of tobacco roots, and keeps the temperature stable for a long time without falling, which significantly improves the effect of low temperature in the early stage of tobacco growth on the root system. The limitation of growth and development promotes the aboveground growth and root system development of flue-cured tobacco, thus laying a good foundation for the stable yield and high quality of tobacco leaves. The temperature-increasing and root-promoting agent prepared by the method of the present invention is used in the tobacco cultivation process, and the temperature increase range is 0.2-0.5°C within 7 days after transplanting, and the temperature-increasing effect is the most significant on the 8th-14th day after transplanting, with an increase rate of 1.0 -2.1°C. At the same time, it can obviously promote the growth of flue-cured tobacco roots and shoots in the cluster stage.

Description

technical field [0001] The invention belongs to the technical field of biological preparations, and relates to a temperature-increasing and root-promoting agent for growing tobacco and a use method thereof. Background technique [0002] From the Wanli period of the Ming Dynasty, my country has a history of tobacco planting. The cultivation of flue-cured tobacco in my country adopts seedling cultivation and transplanting. Seedling cultivation begins around the annual Grain Rains, and harvesting begins in July. The cultivation of flue-cured tobacco is to raise seedlings first, and then transplant the cultivated tobacco seedlings into the field soil. The transplanted tobacco seedlings are required to be strong, sufficient, suitable and uniform. The morphological standard of strong seedlings is that the structure of roots, stems and leaves is reasonable, there are many lateral roots, the root system is developed, and the vitality is strong; the leaf color is normal, the leaf si...
