Embodiment 1

[0017] Weigh each raw material according to the following weight: ethephon 0.2g, methyl jasmonate 0.1g, tryptophan 0.02g, lysine 0.01g, citric acid 0.01g, succinobenzoic acid 0.02g, potassium dihydrogen phosphate 0.05g , 1.5g of silicone additives, dissolved in water and dilute to 1000g (equivalent to about 1000mL) to form a compound preparation. Spray the above-mentioned compound preparation in shelter from rain 20 days before harvest, spray 20mL per square meter of Dendrobium huoshanense seedlings, and continue spraying once after 5 days, spraying 2 times in total. After harvesting, it was processed into a dry product of Dendrobium Huoshanense according to conventional methods, and 10 g of the dry product was weighed and ground into powder to determine its total alkaloid content.

Embodiment 2

[0019] Weigh each raw material according to the following weights: 0.3 g of ethephon, 0.15 g of methyl jasmonate, 0.03 g of tryptophan, 0.018 g of lysine, 0.015 g of citric acid, 0.04 g of succinylbenzoic acid, and 0.06 g of potassium dihydrogen phosphate , silicone additive 1g, dissolved in water and adjusted to 1000g (approximately equivalent to 1000mL) to form a compound preparation. Spray the above-mentioned compound preparation in shelter from rain 26 days before harvest, spray 35mL per square meter of Dendrobium huoshanense seedlings, and continue spraying once after 7 days, spraying 3 times in total. After harvesting, it was processed into a dry product of Dendrobium Huoshanense according to conventional methods, and 10 g of the dry product was weighed and ground into powder to determine its total alkaloid content.

Embodiment 3

[0021] Weigh each raw material according to the following weights: 0.4 g of ethephon, 0.25 g of methyl jasmonate, 0.04 g of tryptophan, 0.02 g of lysine, 0.018 g of citric acid, 0.03 g of succinobenzoic acid, and 0.08 g of potassium dihydrogen phosphate , 2g of silicone additives, dissolved in water and adjusted to 1000g (approximately equivalent to 1000mL) to form a compound preparation. Spray the above-mentioned compound preparation in shelter from rain 30 days before harvest, spray 30mL per square meter of Dendrobium huoshanense seedlings, and continue spraying once after 6 days, spraying 4 times in total.

Abstract

The present invention discloses a compound preparation for increasing an alkaloid content in dendrobium huoshanense. The preparation is prepared from the following raw material components in percentage by weight: 0.02-0.04% of ethephon, 0.01-0.03% of methyl jasmonate, 0.002-0.005% of tryptophan, 0.001-0.003% of lysine, 0.001-0.003% of citric acid, 0.002-0.004% of succinyl benzoic acid, 0.005-0.008% of potassium dihydrogen phosphate, 0.1-0.3% of an organosilicon additive and the balance of water. Dendrobium huoshanense seedling plants are sprayed with the compound preparation avoiding the rain in 20-30 days before dendrobium harvest every year, and the spary amount is 20-40 mL / m2, the preparation is sprayed once every 5-7 days for totally 2-4 times, continuously. By adopting the compound preparation disclosed by the present invention, the total alkaloid content in the dendrobium huoshanense can be remarkably increased.

Description

technical field [0001] The invention relates to a plant growth regulation technology, in particular to a compound preparation for increasing the alkaloid content of Dendrobium Huoshanense. Background technique [0002] Dendrobium (Dendrobium) is a precious and rare medicinal material in my country. It is sweet in nature and slightly cold. It enters the lung, stomach and kidney meridians. There are three kinds produced in Huoshan County, Anhui Province: Huoshan Dendrobium, Copper Dendrobium and Tiepi Dendrobium, among which Huoshan Dendrobium is the top grade of traditional Chinese medicine Dendrobium. [0003] Dendrobium huoshanense, commonly known as rice dendrobium, is a perennial herbaceous plant of the genus Dendrobium orchidaceae. It is limited to Huoshan, Jinzhai, Yuexi, Shucheng and Hubei Yingshan counties in the Dabie Mountains. It contains polysaccharides, alkaloids and Active ingredients such as flavonoids have the effects of enhancing immune activity, improving e...
