Method for planting large-leaved gentian in sloping field

Abstract

The invention relates to a method for planting large-leaved gentian in a sloping field, belonging to the technical field of converting wild species of large-leaved gentian into domestic species, providing a method for planting large-leaved gentian in the sloping field and solving the technology of converting wild species into domestic species and saving precious land resources of China. The technical scheme adopted by the invention comprises the steps of: placing large-leaved gentian seeds in an overwintering mode under the conditions of natural north temperature and more than 85% of humidity for 15 to 90 days; processing the seeds at 12h to 30h before planting; mixing and stirring 0.5 to 2 parts of herbicide and 0.1 to 1 part of herbicide with 10 to 15 parts of seeds to obtain processed seeds; selecting the sloping field with elevation of 1500 to 4300m and gradient of 15 DEG to 55 DEG as a planting field; turning up the field within one week before planting, wherein turning depth is from 15cm to 30cm; fertilizing organic fertilizers of 7000 to 8000kg / hectare; planting the processed seeds in a strip cropping or broadcast sowing mode in the processed field, wherein sowing quantity is from 20 to 30kg / hectare and sowing depth is from 5mm to 15mm; covering a layer of crop straws with the thickness of 10mm to 20mm on the field after planting; and keeping a row spacing of 10cm to 25cm and a plant spacing of 1cm to 15cm in a manual seedling selecting method after seedlings emerge. The method provided by the invention is applied to the technical field of large-scale planting of large-leaved gentian in the sloping field.

Description

technical field [0001] The invention relates to a method for planting Gentiana chinensis on a slope, which belongs to the technical field of Gentiana chinensis wild mutated species, and in particular relates to a method for planting Gentiana chinensis on a large scale on a slope. Background technique [0002] Gentiana is a perennial herb of the family Gentianaceae, and it is one of the main medicines for treating rheumatic arthralgia, tuberculosis hot flashes, jaundice and other diseases. . It is one of the important traditional Chinese medicines in China. It was first recorded in "Shen Nong's Materia Medica" and listed as a middle grade. [0003] Gentiana chinensis grows in areas with an altitude of 400 meters to 2400 meters, mostly on roadsides, meadows, river beaches, ditches, under forests, hillside grasslands and forest margins, and has not yet been introduced and cultivated artificially. Distributed in Mongolia, Siberia and the Far East of Russia, Inner Mongolia, Nin...

[0003] Gentiana chinensis grows in areas with an altitude of 400 meters to 2400 meters, and mostly grows on roadsides, meadows, river beaches, ditches, forests, hillside grasslands and forest edges. It has not been artificially introduced and cultivated

Distributed in Mongolia, Siberia and the Far East of Russia, Inner Mongolia, Ningxia, Hebei, Shaanxi, Xinjiang, Northeast China, Shanxi and other places in mainland China. With the development of my country's pharmaceutical industry and the expansion of the production scale of Chinese herbal medicines, traditional wild digging is no longer possible. To meet the needs, for example, the annual output of wild resources in Shanxi Province is only 30,000 kilograms, and it is getting less and less, and it is not easy to dig. The labor cost is high, but the annual demand in Taiyuan City is as high as 2,300 kilograms. The current market price is 180~210 yuan / kg

[0004] my country has a vast territory, abundant land resources, and complete types of land use, which provide favorable conditions for the comprehensive development of agriculture, forestry, animal husbandry, sideline and fishery production in accordance with local conditions. However, the per capita land resources in my country are small, and various land The proportion is unreasonable, mainly due to less cultivated land, forest land, more difficult-to-use land, and insufficient reserve land resources, especially the contradiction between people and cultivated land. Although my country has solved the problem of food and clothing for 1 / 5 of the world's population, but It should also be noted that the non-agricultural land in my country is increasing year by year, the per capita cultivated land will decrease year by year, and the population pressure on the land will become greater and greater.
