Problems solved by technology

[0002] The nitrogen contained in the conventional tobacco formula nutrient solution is inorganic nitrogen, which has the following disadvantages in use: it can only be used for conventional seedling cultivation, and cannot be used for "green or organic" production, so there is a lack of suitable nitrogen in the growth of tobacco seedlings. Organic nutrition, does not meet the production standards of green tobacco leaves

Abstract

The invention relates to tobacco floating seedling culture nutrient solution and a seedling culture method by using the same. The invention belongs to nutrient solution for plant growth and particularly relates to floating seedling culture nutrient solution (containing organic and inorganic nitrogen) for pollution-free tobacco leaf production and a seedling culture method by using the floating seedling culture nutrient solution. 1000kg of nutrient solution contains the following raw materials by weight: 750-850kg of liquid organic fertilizer, 165-185kg of organic potassium water-soluble fertilizer, 20-30kg of diammonium hydrogen phosphate, 4-6kg of potassium magnesium sulfate and 0.2-0.3kg of borax anhydrous, wherein in the liquid organic fertilizer, the weight percentage of organic nitrogen is 0.15-0.25 percent, the weight percentage of organic matter is 2-3.5 percent, the weight percentage of humic acid is 1.5-2 percent, the weight percentage of iron is 0.035-0.050 percent and the content of zinc is 30-45mg/kg. The nutrient solution provided by the invention can provide organic and inorganic nutrients for tobacco seedling growth at proper time, the cultured tobacco seedlings grow robustly, the production method is compliant with the pollution-free production standard and the nutrient solution can be directly used for pollution-free tobacco leaf production.

Description

technical field [0001] The invention belongs to a nutrient solution for plant growth, and in particular relates to a "green tobacco leaf production" floating seedling-raising nutrient solution (containing nitrogen in two forms, organic and inorganic) and a method for using the seedling-raising solution. Background technique [0002] The nitrogen contained in the conventional tobacco formula nutrient solution is inorganic nitrogen, which has the following disadvantages in use: it can only be used for conventional seedling cultivation, and cannot be used for "green or organic" production, so there is a lack of suitable nitrogen in the growth of tobacco seedlings. Organic nutrition, does not meet the production standards of green tobacco leaves. Contents of the invention [0003] The technical problem to be solved by the present invention is a kind of "green tobacco leaf production" floating nursery nutrient solution and its use method, which can provide organic and inorganic...
