Problems solved by technology

[0003] However, the work of southern propagation not only consumes too much manpower and material resources, but also increases the financial burden of breeding work; and because of the tall tobacco plants, only a small number of tobacco plants can be planted under greenhouse conditions, making winter greenhouse supplementation cost and practical availability There are certain limitations in terms of area
At present, there have been reports of new technologies related to tobacco subgeneration breeding, but this method not only needs to occupy indoor space, temperature control equipment, and artificial light sources, but also requires three stages of operation: substrate germination, water seedling cultivation, and substrate transplanting. It also requires cumbersome operations such as changing the nutrient solution and cutting leaves, and there are many problems such as high facility cost and high labor consumption.

Embodiment 1

[0034] Example 1: Verify the effects of short-day induction and low temperature induction on tobacco seedlings

[0035] The invention discloses a method for adding tobacco based on hydroponics, comprising:

[0036] 1) Treatment of the nutrient pool: flatten the bottom of the nutrient pool and spray insecticides, then spread a black film with a thickness of 0.1mm in the pool, and add water to the nutrient pool; when the indoor temperature is higher than 25°C, once Add water to 15cm; when the indoor temperature is lower than 25°C, the water layer should be controlled at 5cm. If the water level drops, replenish water to the initial water level in time; the depth of the nutrient pool is 15cm, the length is 15m, and the width is 0.85m;

[0037] 2) Packing and sowing: adjust the water content of the packing matrix to 35%, put it into the plug-in tray, and sow the tobacco seeds in the packing matrix at the same time, the sowing depth is 3mm, and cover the seed surface with 2mm after ...

Embodiment 2

[0046]Embodiment two, verify the impact of packing substrate on the emergence rate, survival rate and growth cycle of tobacco seedlings:

[0047] A method for adding tobacco based on hydroponics, comprising:

[0048] 1) Treatment of the nutrient pool: flatten the bottom of the nutrient pool and spray insecticides, then spread a black film with a thickness of 0.1mm in the pool, and add water to the nutrient pool; when the indoor temperature is higher than 25°C, once Add water to 15cm; when the indoor temperature is lower than 25°C, the water layer should be controlled at 5cm. If the water level drops, replenish water to the initial water level in time; the depth of the nutrient pool is 15cm, the length is 15m, and the width is 0.85m;

[0049] 2) Packing and sowing: adjust the water content of the packing substrate to 30%, 32%, 34%, 36%, 38%, and 40%, respectively, and put the substrates with different water contents into different plugging trays, Simultaneously the tobacco see...

Embodiment 3

[0058] Embodiment three: Verify the influence of temperature on the emergence rate of tobacco

[0059] A method for adding tobacco based on hydroponics, comprising:

[0060] 1) Treatment of the nutrient pool: flatten the bottom of the nutrient pool and spray insecticides, then spread a black film with a thickness of 0.1mm in the pool, and add water to the nutrient pool; when the indoor temperature is higher than 25°C, once Add water to 15cm; when the indoor temperature is lower than 25°C, the water layer should be controlled at 5cm. If the water level drops, replenish water to the initial water level in time; the depth of the nutrient pool is 15cm, the length is 15m, and the width is 0.85m;

[0061] 2) Packing and sowing: adjust the water content of the packing matrix to 35%, put it into the plug-in tray, and sow the tobacco seeds in the packing matrix at the same time, the sowing depth is 3mm, and cover the seed surface with 2mm after sowing Then put the Jiadai plug tray int...

Abstract

The invention discloses a tobacco generation adding method based on water culture. The method specifically comprises the steps as follows: treatment of a nutrient pool, loading and sowing, temperaturecontrol, water and fertilizer control, reproduction induction, chemical control, flower and fruit thinning and the like. The tobacco generation adding method overcomes defects in the prior art, technical measures such as soilless culture in the whole growth period, close planting and dwarf tretament are adopted, and a one-procedure type tobacco generation adding method with high efficiency and low cost is explored.

Description

technical field [0001] The invention relates to the technical field of tobacco multiplication and substituting, in particular to a method for adding and substituting tobacco based on hydroponics. Background technique [0002] Southern breeding is an important link in many plant breeding and genetic research work, which can speed up the breeding process and improve breeding efficiency; tobacco is not only an important economic crop, but also a model plant for genetic research. Population construction or genetic research in genetic research Genetic breeding materials usually have hundreds or thousands of lines, and the traditional way of adding tobacco is to breed in the south or use a greenhouse with light and temperature control facilities for breeding. [0003] However, the work of southern propagation not only consumes too much manpower and material resources, but also increases the financial burden of breeding work; and because of the tall tobacco plants, only a small num...
