Description
Technical Field
The invention relates to a cultivation method for prolonging the ornamental period of ginkgo yellow leaves, in particular to a cultivation method for prolonging the ornamental period of ginkgo yellow leaves, relating to the technology of changing color of leaves in advance and delaying yellow leaf falling, which is a method for prolonging the ornamental period of ginkgo, and particularly can meet the ornamental requirement of yellow leaves in autumn and winter.
Background
The semen Ginkgo is a large tree of folium Ginkgo. The gingko has strong vitality, wide distribution and higher ornamental, material and medicinal values.
The gingko is popular with people due to the unique tree shape and leaf shape and bright yellow leaves, and is widely planted in a plurality of ecological areas of China in landscaping. Under normal conditions, the temperature in autumn is lower than 10 ℃, and the ginkgo leaves begin to turn yellow. In special years, due to drought and rain, the gingkoes can turn yellow and even fall leaves in summer.
Ginkgo biloba is a fleshy root, has strong adaptability but poor resistance, and can cause premature senility, early yellowing and even leaf drop due to waterlogging, drought and pollution. The production practice shows that the gingko is cultivated most in Shandong and Subei areas in China, and sandy loam in the areas is suitable for the gingko to grow; however, in the areas of rivers and Huai which are rainy but often arid, the areas often turn yellow or fall leaves due to waterlogging and drought. In key scenic spots, loose, breathable and nutrient-rich ginkgo culture mediums can be artificially prepared by utilizing the characteristics of ginkgo, the moisture content is controlled, the purpose of water stress is achieved, the yellowing process of the leaves of the ginkgo is controlled, the yellow leaf viewing time of the ginkgo can be prolonged, and the requirements of the development of leisure agriculture in new periods are met.
Disclosure of Invention
The invention aims to solve the technical problem of short ornamental period of ginkgo yellow leaves. Aiming at the problem of short ornamental period of yellow leaves of ginkgo, a novel cultivation method for regulating the ornamental period of the yellow leaves of ginkgo by cultivating the ginkgo with formula cultivation soil is provided according to the characteristic that the ginkgo is poor in resistance and is easy to discolor under stress conditions such as drought. Starting in 9 months, if the cultivation is forced by rain sheltering measures in rainy days, the ginkgo leaves are turned yellow, and the ornamental time can be advanced by 12-16 days. The method is characterized in that:
1. the cultivation soil is simple in composition and easy to take, and is particularly sandy soil, surface soil, garden plant dead branches and fallen leaves and stones.
2. The proportion of the cultivation soil is 30 percent of sandy soil, 30 percent of surface soil, 30 percent of garden plant dead branches and fallen leaves and 10 percent of decomposed cake fertilizer (v/v). The materials are collected nearby, the fallen leaves of the dry branches in the nursery are common in the east China and other areas, the fallen leaves of the dry branches can be collected nearby, the dry branches and the fallen leaves are properly crushed, uniformly mixed and watered thoroughly, the mixture is covered with transparent plastic cloth, the mixture is piled and retted for about 40 days in spring and summer, and the piling and retting time is properly prolonged in autumn and winter.
3. Filling the planting holes with the uniformly mixed cultivation soil, and stacking 30-35 cm of the cultivation soil with the proportion above the planting holes, wherein the soil stacking is beneficial to controlling water.
4. Planting gingkoes with the diameter at breast height of more than 6cm, wherein the plant-row spacing is 3.0-4.0 m multiplied by 3.0-5.0 m.
5. And (3) applying 100-150 g of urea per plant in a hole in 3-7 months every year, spraying 0.5% of monopotassium phosphate on the leaf surfaces for 1 time in 8 middle-ten days of the month, and culturing healthy plants and leaves.
6. Beginning in the last ten days of 9 months, protecting the ginkgo leaves by rain sheltering facilities such as plastic cloth and the like, and carrying out drought stress to ensure that the water content of the cultivation soil of the peripheral root systems of the ginkgo leaves is gradually reduced to about 20 percent, the leaf color at the bottom of 9 months gradually turns yellow, and the ornamental period of the yellow leaves can be advanced by 12-16 days.
7. After the ginkgo leaves turn yellow, the water is thoroughly poured in the evening once a week, and the ginkgo leaf period can be prolonged to 11 middle and last days.
The cultivation soil has simple formula, local material selection and easy operation. With the increase of ornamental demand of autumn leaves, technology for prolonging the leaf-viewing period of yellow-leaf ginkgo is more and more emphasized, and under the premise of healthy growth of branches and leaves of ginkgo, the yellow-leaf time of ginkgo is prolonged, the ornamental value of ginkgo can be increased, and the application prospect is wide.
The specific implementation mode is as follows:
a cultivation method for prolonging the ornamental period of yellow ginkgo leaves comprises the following steps: specifically, ginkgo seedlings with the diameter at breast height of more than 6cm are selected, shallow planting holes are dug, the ginkgo seedlings are piled on the planting holes with the thickness of 30-35 cm, the planting soil is prepared from 30% of sandy soil, 30% of surface soil, 30% of garden plant dead branches and fallen leaves and 10% of rotten cake fertilizer, and the ginkgo seedlings are planted with the row spacing of 3.0-4.0 m multiplied by 3.0-5.0 m.
And (3) applying 100-150 g of urea per plant in a hole mode every 3-7 months every year for 8 months, spraying 0.5% monopotassium phosphate on the leaf surfaces for 1 time, and culturing healthy plants and leaves. Beginning in the last ten days of 9 months, protecting the ginkgo leaves by rain sheltering facilities such as plastic cloth and the like, and carrying out drought stress to ensure that the water content of the cultivation soil of the peripheral root systems of the ginkgo leaves is gradually reduced to about 20 percent, the leaf color at the bottom of 9 months gradually turns yellow, and the ornamental period of the yellow leaves can be advanced by 12-16 days. And then, watering thoroughly once in the evening every week, wherein the leaf-viewing period of the gingko can be prolonged to 11 middle and last days of the month.
The formula of the cultivation soil used in the embodiment is selected according to the color change characteristic of the ginkgo leaves; shallow hole digging and high soil stacking field planting are adopted, and the technology of rain-sheltering cultivation facilities such as plastic films is favorably implemented; the drought stress method is based on the results obtained by production, test and observation for many years; the density of gingko permanent planting can be adjusted according to actual needs so as to obtain the best ornamental value and economic benefit.
