GAP (good agricultural practices) cultivation technique for leaf-harvesting ginkgo garden with red soil

Abstract

The invention discloses a GAP (good agricultural practices) cultivation technique for a leaf-harvesting ginkgo garden with red soil. By the GAP cultivation technique, the yield and quality of ginkgo can be effectively improved and the standardization and industrialization of leaf-harvesting ginkgo planting in red soil in south of China are promoted. The GAP cultivation technique comprises building and management technique of the leaf-harvesting ginkgo garden, methods of seed selection, seed planting stage, planting density and fertilization of the leaf-harvesting ginkgo, field management, disease and pest prevention and control method, ginkgo leaf harvesting stage and harvesting method, and methods for medicinal material field processing and storage. By adopting the technical scheme disclosed by the invention, high-quality raw medicinal material is provided for traditional Chinese medicine extract and Chinese patent drug pharmaceutical enterprises; and the GAP cultivation technique has very important effect of guaranteeing the safety, high efficiency, stability and controllable quality of the traditional Chinese medicine extracts and Chinese patent drugs.

Description

technical field [0001] The invention relates to a cultivation technology, in particular to a GAP cultivation technology of red soil leaf ginkgo orchards. Background technique [0002] GAP of Chinese herbal medicines: Good Agricultural Practices (GAP for short) of Chinese herbal medicines. Ginkgo biloba L. is commonly known as ginkgo tree.

Problems solved by technology

For a long time, there have been a series of quality problems such as poor consistency in the appearance and quality of medicinal materials; unstable content of active ingredients in medicinal materials; heavy metals and pesticide residues in products exceeding the standard, failing to meet the basic requirements of green products; seriously affecting the safety and effectiveness of traditional Chinese medicine and other quality problems

The reason is that the cultivation method of ginkgo medicinal materials is still based on the cultivation of each household of the farmers, with decentralized management. During the cultivation process, the operating techniques and methods are inconsistent, and it is difficult to ensure the stable and high yield of the medicinal materials and the stability and uniformity of the active ingredients.
