Nicotiana tabacum floating seedling raising special-purposed nursing fertilizer and preparation method thereof

Abstract

The embodiment of the invention provides a nicotiana tabacum floating seedling raising special-purposed nursing fertilizer and a preparation method thereof, and relates to the field of fertilizer preparation. With the fertilizer, nicotiana tabacum seedbed stage growing condition can be improved, and the production of robust seedlings is ensured. The special-purposed nursing fertilizer comprises the following components, by weight, calculated according to a total nursing fertilizer weight of 1500g: a component I comprising 0.4-0.6g of 6-benzylaminopurine, 0.8-1.5g of forchlorfenuron, 5ml of anhydrous ethanol, and 500ml of distilled water; a component II comprising 400-550g of tenebrio moliter mature larvae powder, 250-300g of an yeast extract, 100-150g of glucose, 28-35g of gellan gum, 10-15g of trehalose, and 28-35g of agar powder; a component III comprising 8-12g of magnesium chloride, 8-12g of potassium chloride, 0.8-1.3g of salicylic acid, 2.5-3.5g of 98% 1,2-butanediol, and 500ml of distilled water; and a component IV comprising 400-500g of deactivated dried soy beans.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a special nursery fertilizer for floating seedling raising of tobacco and a preparation method thereof. Background technique [0002] Tobacco (Nicotiana tabacum L.) is an important economic plant and a model plant for scientific research. Tobacco cultivation technology has developed from the extensive management mode before the 1980s to the intensive management mode today. With the continuous deepening of research, more efficient and novel cultivation techniques and theories are constantly being produced. From a cultivation point of view, tobacco floating seedling cultivation has become a mainstream technology and immobilized production mode in tobacco production areas. However, objectively speaking, there are still large differences in the effects and awareness of the application of floating seedling technology in different regions. Many extensive deficiencies have been ex...

Problems solved by technology

The application of existing seed coatings has promoted the development of seedling production to a certain extent, but there are also some problems at the same time, which are mainly reflected in several aspects: (1) The traditional seed coating formula is affected by cost, plant seed characteristics, human factors, etc. Due to various constraints, the formula of seed coatings is the same, lacks innovation, and is poorly targeted; (2) Traditional seed coatings often lack organic nutrition requirements in the seedbed stage due to the limitation of formula components; (3) There is no targeted Special nursery fertilizer for floating seedlings of economical plant tobacco
