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

Embodiment

[0023] like figure 1 Shown a kind of Tanggut rhubarb and coriander root interplanting cultivation method, comprises the following steps:

[0024] Level the land, apply base fertilizer, turn ploughing and smashing and harrow level; ditch according to row spacing 50cm, ditch 2cm deep, and plant spacing 25-50cm to drill the seeds of Tanggut rhubarb 101; ditch the middle of the row spacing of Tanggut rhubarb 101 seeds , the ditch is 1cm deep, and the seeds of Coriander root 102 are sown according to the plant spacing of 8-15cm; after the above-mentioned two kinds of seeds emerge, topdressing is carried out twice in July and August respectively, and the seedlings are thinned in mid-July.

[0025] Preferably, the base fertilizer is diammonium phosphate, and the fertilization rate is 20-30 kg / mu.

[0026] Preferably, the seeding rate of the seeds of the tangute rhubarb is 4.5-5.5 kg / mu.

[0027] Preferably, the seeding rate of the seeds of Radix Root is 0.8-1.2 kg / mu.

[0028] Pre...

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 ...
