Method of planting gentiana macrophylla

Abstract

The invention discloses a method for planting gentiana macrophylla. The method includes the following steps that 1, selection, storage and processing are conducted, wherein seeds are selected and stored; 2, mulching planting is conducted, wherein soil preparation, fertilization, ridging, mulching, mulch punching, sowing, seedling checking and thinning are conducted in sequence, sowing is conducted in the period from the middle ten days of March to the beginning of April, seeds are sowed in holes, the treated gentiana macrophylla seeds are mixed with toxic sand in a ratio of 1:(8-10) and then sowed, and the holes are covered with a layer of thermal-insulation water permeable material formed by mixing fly ash, field soil, dry horse dung and fine sand after sowing and then are filled with soil; 3, field management is conducted, wherein weeding, overwinter management and topdressing are conducted in sequence; 4 harvesting is conducted. By means of the method for planting the gentiana macrophylla, the seedling emergence time is advanced from about 30 days to about 28 days, the survival rate is up to 98.7% or above, seedlings grow strong, and the incidence rate is less than 2.3%.

Description

Technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and in particular relates to a planting method of Gentiana macrophylla. Background technique [0002] Gentiana is a perennial herb of the Gentianaceae Gentian family, which grows in subalpine grasses and shrubs at an altitude of 2000-4950m. Its root is used as medicine, and it has the effects of expelling wind and dampness, relieving deficiency and heat, relieving arthralgia, strengthening stomach, and promoting choleretics. It is one of the important traditional Chinese medicines in China and is listed as a national three-level key protected medicinal plant. In recent years, due to the in-depth development of Chinese medicine, the market demand for Gentiana sylvestris has increased. However, the traditional gentian roots are mainly harvested from the wild, leading to over-excavation and declining wild resources. In order to alleviate its endangerment and protect the reso...

Problems solved by technology

However, in this method, when the seeds are stored at variable temperatures, the respiration intensity of the seeds is different due to different temperatures. Although the respiration intensity of the seeds is very weak under low temperature conditions, the temperature at the initial and final stages of storage has reached 20°C. The high strength makes the nutrient consumption in the seeds serious. After sowing, the breathing stamina is insufficient due to the serious consumption of seed storage, which in turn delays the emergence speed and seedling growth.

Simultaneously, when this method is processing the soil, only use phoxim granule mixed with the soil to treat the ground surface, which has little effect on the pathogenic bacteria and insects in the deep layer of the soil. Therefore, the probability of disease invasion after the seeds are sown is very high, and it is difficult to ensure that the seeds germinate and Seedling quality
