Abrotanum crop rotation method

Abstract

An abrotanum crop rotation method is characterized in that the crop rotation method comprises alternately planting abrotanum and another plant. Abrotanum and tuber mustard or rape use crop rotation, thereby improving the land utilization rate, increasing the economic benefit. Abrotanum and tuber mustard use crop rotation, and the yield number per mu is increased by 1200-1600 yuan compared with pure planting of abrotanum and is more than twice compared with pure planting of abrotanum; and abrotanum and rape use crop rotation, and the yield number per mu is increased by 600-801 yuan compared with pure planting of abrotanum and is more than 1.5 times compared with pure planting of abrotanum. Simultaneously, since a large number of dry leaves after tuber mustard and rape are harvested are returned back to the farmland, thereby increasing soil humus and improving soil fertility. Therefore, the fertilizing amount of abrotanum can be reduced correspondingly, and the costs of labor and fertility are decreased.

Description

technical field [0001] The invention relates to a method for planting medicinal crops, in particular to a method for planting Artemisia annua. Background technique [0002] Artemisia annua (Artemisia annua L.) is a herb of the genus Artemisia in the family Asteraceae. It tastes bitter, pungent, and cold in nature. It has the functions of clearing away heat and relieving heat, removing lice, and cutting off malaria. It is one of the traditional antimalarial drugs of traditional Chinese medicine. A large number of physical and chemical experiments, pharmacological research and clinical application research at home and abroad have shown that artemisinin, one of the effective extracts of Artemisia annua, is an effective antimalarial component, and has now become an antimalarial drug recommended by the World Health Organization, especially for brain It has a good effect on type malaria and chloroquine-resistant malaria. At present, although artemisinin has been artificially syn...

Problems solved by technology

At present, although artemisinin has been artificially synthesized, it has not been put into production. Therefore, the main source of artemisinin is still the separation and extraction from Artemisia annua.

[0003] Usually, Artemisia annua is abandoned after one season, the land utilization rate is low, and the economic benefits are poor. In addition, the plants of Artemisia annua are tall, and a large amount of nutrients such as nitrogen, phosphorus, and potassium must be taken away from the soil. Therefore, fertilization is applied during the growth of Artemisia annua. The number of times and the amount of fertilization are large, which naturally increases the economic burden of the drug farmers.
