Embodiment 1

[0026] Choose a small field, the flue-cured tobacco variety is Yunyan 87, and plant 60 tobacco plants, arranged according to 15 plants / row, and the row-to-plant distance is 1m×0.5m. No pesticides were used throughout the growth period, and other cultivation management measures were the same as conventional field production. The liquid micro-fertilizer consists of: EDTA-Zn 0.2%; ammonium phosphomolybdate 0.5%; ethanol 5%; the balance is water

[0027] Select tobacco strain at random and handle according to the following conditions: 1, every plant 50g liquid micro-fertilizer is sprayed by 500 times of dilution; 2, every plant 50g liquid micro-fertilizer is sprayed by 1000 times of dilution; Spray according to the dilution of 2000 times; 4. Only spray water, do not add liquid micro-fertilizer. The number of treatments in each case was 15 plants, and they were applied once in the rapid growth period of tobacco or 1 week after topping, or once in the rapid growth period and 1 week...

Embodiment 2

[0042] Tobacco seedling planting and squalene extraction and detection are shown in Example 1.

[0043] The liquid micro fertilizer is composed of: 2% EDTA-Zn; 6% ammonium phosphomolybdate; 8% ethanol; the balance is water.

[0044]Randomly select tobacco strains to process according to the following conditions: 1, 30g liquid micro-fertilizer per plant, sprayed by 500 times of dilution; 2, 30g liquid micro-fertilizer per plant, sprayed by 1000 times of dilution; 3, 30g liquid micro-fertilizer per plant , according to the dilution of 2000 times spraying; 4, only spray water, do not add liquid fertilizer. The number of treatments in each case was 15 plants, and they were applied once in the rapid growth period of tobacco or 1 week after topping, or once in the rapid growth period and 1 week after topping.

Abstract

The invention discloses a liquid microelement fertilizer and an application thereof to improve a squalene content in tobacco leaves. The liquid microelement fertilizer comprises, by weight percentage, 0.2-5% of EDTA-Zn, 0.5-10% of ammonium phosphomolybdate, and 5-10% of ethanol, with the balance being water. During a growth process of tobacco, through addition of the liquid microelement fertilizer, the squalene content in tobacco leaves is obviously improved, and the economic value of tobacco leaves is increased.

Description

technical field [0001] The invention relates to the field of tobacco planting, in particular to a liquid micro-fertilizer and its application in increasing the content of squalene in tobacco leaves. Background technique [0002] Squalene is a lipid unsaponifiable substance, which is a polyunsaturated olefin (tricosahexaene), which was originally discovered from shark liver oil. It was named Squalene in 1914, and its chemical name is 2, 6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaene, which is an open-chain triterpene, also known as cod liver oil terpene, participates in the synthesis of cholesterol in the human body and can It promotes metabolism, has many physiological functions such as increasing the activity of superoxide dismutase (SOD) in the body, enhancing the body's immunity, anti-aging, anti-fatigue, anti-tumor, etc. It is a non-toxic marine organism with the effect of preventing and curing diseases active substance. [0003] Squalene widely exists in an...
