Problems solved by technology

Repeated use of herbicides will reduce the weeding effect, which is a potential environmental pollution factor
The traditional planting method requires a large amount of fertilization, focusing on yield and neglecting land cultivation. After many years of cultivating ginkgo for leaves, the soil of the cultivated land is compacted, the structure is destroyed, and the loss of nutrients is very serious.

Embodiment

[0036] A kind of leaf ginkgo fertilizer exempting weed-free cultivation method, comprises the steps:

[0037] The first step, planting site selection

[0038] The fifth group of Shiwu Village, Longtian Town, Ningxiang County is the planting test site. The test site is 295 meters above sea level and the area is 1.2 mu. The previous crop is corn, and the previous crop rotation mode is vegetable-corn. The soil color is Gray-black, the parent material of the soil is weathered granite, the soil layer is deep, the live soil layer is more than 100 cm deep, the soil pH value is 6.4, it is judged as medium fertility soil according to NY-T309-1996, the irrigation condition is gravity irrigation, and the drainage condition is good ;

[0039] The second step, the preparation of the planting site

[0040] On the planting site, after the corn was harvested, on August 20, 2014, 50kg of lime was applied per mu, and a large tractor was used to plow the soil, and the drainage ditch was opened...

Abstract

The invention provides a fertilizer-saving and weeding-free cultivation method of leaf-harvesting ginkgoes. The method includes the following steps that firstly, a planting site is selected; secondly, the planting site is prepared; thirdly, the planting site is managed; fourthly, caving, fertilizing and transplanting of ginkgoes are carried out; fifthly, film removing and fertilizer implanting are carried out; sixthly, management after sowing is carried out; seventhly, multi-year management is carried out. By means of the method, the problems that the existing fertilizing amount is large, more attention to the yield and less attention to land maintenance are executed, after the leaf-harvesting ginkgoes are planted for many years, arable soil is hardened, the structure is damaged, and the nutrient loss phenomenon is very serious can be solved.

Description

technical field [0001] The invention relates to a method for cultivating ginkgo for leaves, in particular to a method for cultivating ginkgo for leaves without fertilizer and weeds. Background technique [0002] ginkgo( Ginkgo biloba L. ) is a kind of relict tree unique to our country, which is a deciduous tree of Ginkgoceae and Ginkgo genus. Ginkgo biloba is an ancient traditional Chinese medicine. It can prevent and treat cardiovascular and cerebrovascular diseases. Medicinal value and edible value. The medicinal active ingredients in ginkgo leaves - ginkgolides and ginkgo flavonoids - have the highest content in the 2nd to 8th year of ginkgo tree growth, and the content gradually decreases and loses its utilization value after 8 years of planting. In order to increase the yield of leaves and the content of active ingredients in the leaves of Ginkgo biloba, the planting method of Ginkgo biloba is mainly dwarfed and densely planted, that is, the production level is guara...
