A kind of interplanting cultivation method of Tangut rhubarb and coriander root

Abstract

The invention relates to the field of agricultural planting, in particular to a cultivation method of interplanting rheum tanguticum with yuenkanin. The method includes the steps of leveling the land, applying base fertilizers, plowing and breaking to rake; in accordance with the row spacing of 50-80 cm, ditching by depth of 2 cm and plant spacing of 25-50 cm to sow rheum tanguticum seeds; ditching in the middle of row spacing of rheum tanguticum by the depth of 1 cm, and sowing yuenkanin seeds according to plant spacing of 8-15 cm; after the two kinds of seeds germinate, conducting topdressing two times in July and August respectively. The rheum tanguticum and the yuenkanin grow together, wherein as a biennial plant, the yuankanin can be harvested in October of the planting year; with a rapid growth speed, the yuankanin can quickly occupy the intermediate space of the rheum tanguticum, thereby preventing weeds from spreading, and reducing the field weeding cost of the rheum tanguticum. According to the cultivation method of interplanting medicinal plants of rheum tanguticum with forage plants of yuenkanin, the large-scale industrialization plantation of the rheum tanguticum and yuenkanin can be achieved, thereby realizing double incomes, and achieving the purpose of adjusting planting structure for the vast Qinghai Tibet Plateau pastoral areas.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for intercropping cultivation of Tanggut rhubarb and coriander root. Background technique [0002] Rheum tanguticum Maxim.ex Regel is a tall, perennial herb of the genus Rheum in the family Polygonaceae; the stem is erect, together with the inflorescence up to 2m, the root is thick and thick, the diameter is up to 10cm, and the root length is 30-100cm. The main producing area of ​​Tanggut rhubarb is Qinghai Plateau, which is the original plant of the famous authentic local medicinal materials in Qinghai. Mainly distributed in Qinghai Province, northern Sichuan and southwestern Gansu and other places. Tanggut rhubarb in our province is mainly distributed in forest areas, meadows and degraded meadow areas of Guoluo, Haidong, Haibei, Huangnan and Yushu. The geographical range is roughly 32°31′-39°05′N, 97°49 '-103°04'E, 2800-4700m above sea level. Tanggut rhubarb is ...

Problems solved by technology

However, the high cost of artificial weeding in medicine fields has always been an important factor restricting the development of this industry.

[0003] The present invention is based on the fact that the 1-2 year-old Rhubarb Tangut plants are relatively short, the distribution range of the root system is relatively narrow, and it is difficult for the leaf surface to cover the ground, and the 3-year-old plants grow tall, and the coverage of the bushes reaches 1㎡ / plant. The planting requirements of Rhubarb Tangut are relatively Large row spacing, generally 50-80cm; however, weeds are easy to grow in the open space between the rows in the first year and the second year of Tangut rhubarb planting, there is a lack of professional herbicides, and the cost of manual weeding in the field is relatively high. development
