Problems solved by technology

At present, tobacco farmers in various tobacco leaf producing areas rely too much on the use of potassium and phosphorus fertilizers, which has caused obvious symptoms of nutritional imbalance in the field growth period of flue-cured tobacco, such as potassium and calcium, magnesium antagonism, phosphorus and zinc antagonism, and tobacco planting in various tobacco areas. The soil itself is deficient in trace elements such as boron, zinc, and molybdenum to varying degrees, which exacerbates the symptoms of nutritional disorders such as boron deficiency, magnesium deficiency, and zinc deficiency in the late stage of tobacco growth (bud and mature stage).

Embodiment 1

[0025] Weighing: Potassium dihydrogen phosphate (KH 2 PO 4 ) 10.208kg, magnesium sulfate heptahydrate (MgSO 4 ·7H 2 O) 7.394kg, zinc sulfate heptahydrate (ZnSO 4 ·7H 2 O) 0.216kg, borax (Na 2 B 4 o 7 10H 2 O) 0.357kg, ammonium molybdate ((NH 4 ) 2 Mo 2 o 7 )0.051kg; L-malic acid (C 4 h 6 o 5 )37.538kg, glutamic acid (C 5 h 9 NO 4 )44.211kg, brassinolide (C 28 h 46 o 6 ) 0.025kg, the medium and trace element substances are fully mixed and evenly prepared for later use; then brassinolide, glutamic acid and L-malic acid are evenly mixed, and finally the mixed two groups of mixtures are put into a stirring solution Fully stir in the container; after taking it out, use a vacuum sealing machine to seal 100g in each bag. When using, mix 100g of powder foliar fertilizer with 15kg of water, stir until completely dissolved, spray 45kg of the diluted solution per 666m2, and spray once in a timely manner with a motorized sprayer in the long-term growth of the flue-cur...

Embodiment 2

[0026] Embodiment two: take by weighing: potassium dihydrogen phosphate (KH 2 PO4 )5.104kg, magnesium sulfate heptahydrate (MgSO 4 ·7H 2 O) 3.697kg, zinc sulfate heptahydrate (ZnSO 4 ·7H 2 O) 0.108kg, borax (Na 2 B 4 o 7 10H 2 O) 0.179kg, ammonium molybdate ((NH 4 ) 2 Mo 2 o 7 )0.026kg; L-malic acid (C 4 h 6 o 5 ) 18.769kg, glutamic acid (C 5 h 9 NO 4 ) 22.105kg, brassinolide (C 28 h 46 o 6 ) 0.012kg, solvent water 50kg. First add glutamic acid and malic acid into 5kg of solvent water and stir evenly, then add zinc sulfate, borax, magnesium sulfate and other medium and trace elements in turn, and finally add brassinosteroid, and mix thoroughly with a stirrer in a clean container. Mix evenly, and finally add 45kg of solvent water and mix evenly. When using, mix 15kg of water for every 200g of water-based foliar fertilizer, every 666m 2 Spray 45 kg of the diluted solution, and spray once in time with a motorized sprayer respectively during the vigorous grow...

Abstract

The invention discloses a leaf fertilizer special for tobacco, which comprises monopotassium phosphate, magnesium sulfate heptahydrate, zinc sulfate, borax, ammonium molybdate, L-malic acid, glutamic acid, brassinolide and solvent water. Inorganic and organic nutrient substances are provided for the growth of tobacco to meet the basic growth requirement of tobacco; for example, magnesium, boron and zinc are medium trace nutrient elements deficient at the tobacco zone in Hubei; the glutamic acid and the malic acid can be directly involved in certain important metabolic activities during the growth of tobacco, in particular tricarboxylic acid cycle, and promote the growth of tobacco in the later stage to timely switch from nitrogen metabolism into carbon metabolism, so as to improve maturity and quality; and the plant growth modifier, brassinolide, can induce to strengthen the immunity of tobacco and improve the virus and fungal disease resisting capability of tobacco.

Description

technical field [0001] The invention relates to a plant foliar fertilizer which coordinates the growth of tobacco and balances the carbon and nitrogen metabolism in the mature stage, in particular to a special foliar fertilizer for tobacco. Background technique [0002] The known agricultural production foliar fertilizers can be divided into three classes according to the objects used, namely the foliar fertilizers for field gramineous crops, the foliar fertilizers used on trees such as fruit trees, and the economical products such as tobacco, vegetables and tea leaves that mainly harvest leaves. Foliar fertilizers used by crops; according to the morphological characteristics of foliar fertilizers, they can be divided into solid and liquid. The solid ones are mainly powders, and the liquid ones are mainly emulsions; they can be roughly divided into three categories according to their functions. That is, the growth-promoting type mainly based on nutrients, the growth-stimulat...
