[0044] Organic Cultivation Method of Leaving Ginkgo Biloba
[0045] (1) Construction of an organic production base: select a contiguous base with a deep soil layer as an organic production base for picking leaves of ginkgo. There is no obvious pollution source within 2km around the plot, and the soil environmental quality is required to meet the secondary standard in GB15618. The water used complies with the water quality standards for fruit and vegetable irrigation in GB5084, does not use all kinds of sewage and waste water even if the discharge reaches the standard, and the air environment quality of the base meets the provisions of the second-level standard of GB3095;
[0046] (2) Production during the conversion period: 24 months before planting ginkgo, plant soybeans and corn stubble respectively;
[0047] (3) Isolation zone setting: Set up a 5m-wide isolation zone between the leaf-picking ginkgo organic production base and the conventional base, including drainage ditche...

Abstract
The invention discloses an organic cultivation method for leaf-picking ginkgo biloba. The organic cultivation method comprises the steps that at least one circle of isolation strip is arranged aroundan organic production base for planting the leaf-picking ginkgo biloba, and after the organic production switching period, the leaf-picking ginkgo biloba is planted in the organic production base, wherein the switching-period crops planted in the organic production switching period are provenances with non-genetically modified organisms, and the width of the isolation strip is 5-6 m; at least onecircle of drainage ditch around the organic production base is arranged on the isolation strip; before or while the leaf-picking ginkgo biloba is planted, at least one circle of isolation crop aroundthe organic production base is planted on the isolation strip, and a 2.5-3-meter high isolation shield is formed by the isolation crop which is trichosanthes kirilowii maxim. By means of the organic cultivation method, the organic planting level of the leaf-picking ginkgo biloba can be effectively improved, and the safety of the obtained ginkgo biloba leaves can be ensured.
Description
technical field [0001] The invention relates to an organic cultivation method of leaf-plucked ginkgo. Background technique [0002] Ginkgo biloba is one of the oldest relict plants in the existing gymnosperms. It is native to China and has a long history of cultivation. Ginkgo biloba leaves are the dry leaves of Ginkgo biloba, harvested in autumn when the leaves are still green, and dried in time; Ginkgo biloba leaves are rich in flavonoids, which have the function of scavenging free radicals, and have strong protection against cell damage and chromosomal aberrations caused by free radicals effect. With the deepening of people's understanding of the pharmacological effects of Ginkgo biloba, the requirements for its quality and safety are also increasing, especially for tea-based Ginkgo biloba. In the traditional leaf-picking ginkgo planting process, in order to increase yield and prevent pests and weeds, chemical fertilizers and chemicals are used, especially spraying chem...
