Direct seeding and interplanting method for gentiana macrophylla

Abstract

The invention discloses a direct seeding and interplanting method for gentiana macrophylla, and belongs to the technical field of agriculture. The direct seeding and interplanting method comprises the following steps that step 1, sowing is carried out; 1.1, seeds are collected, specifically, gentiana macrophylla which grows for more than 3 years is selected as a seed collection field, and the seeds are selected from the end of August to September every year; 1.2, in the sowing period, spring sowing and autumn sowing are selected according to different interplanting crops, the interplanting crops comprise wheat, flax, oilseed rape, corn and broad beans, and the sowing amount is 2-2.5 kg per mu; 1.3, a sowing method comprises the steps that after the crops are normally planted, the gentiana macrophylla seeds are mixed with fine sand or fine cotton soil, uniformly spraying and sowing are carried out, a rake is used for lightly scribing on the ground surface, and the ground surface soil is lightly pat by using a flat-bottom shovel to enable the gentiana macrophylla seeds to be in close contact with the soil; and step 2, management is carried out. By applying the direct seeding and interplanting method for gentiana macrophylla, the planting success rate is increased, meanwhile, the planting cost of the gentiana macrophylla can be greatly reduced, the working procedures of seedling raising and transplanting are eliminated, labor and time are saved, other crops in one season are harvested while the gentiana macrophylla is planted, and economic income is increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a direct-seeding interplanting method of Gentiana chinensis. Background technique [0002] Due to the long growth cycle and low yield of Gentiana chinensis, there is no standardized cultivation technology, and it is impossible to supply high-quality varieties and high-quality seedlings to farmers. The benefits of domestic planting are not high, and the planting scale is small. At present, Gentiana chinensis mainly supplies the market with wild resources. As a national third-level key protected wild medicinal species, it needs to be planted artificially to meet the increasing needs of people. At present, artificial cultivation is still in its infancy. Due to the backward cultivation technology and low economic benefits, artificial planting relies more on experience, and some key technical problems have not been resolved, such as: difficulty in emergence and preservation of seed...

Problems solved by technology

At present, artificial cultivation is still in its infancy. Due to the backward cultivation technology and low economic benefits, artificial planting relies more on experience, and some key technical problems have not been resolved, such as: difficulty in emergence and preservation of seedlings, disordered germplasm, backward field management, lack of scientific guidance for fertilization, pests and diseases Serious, the quality and yield are low, seriously affecting the quality of medicines and dampening farmers' enthusiasm for planting
