Description

Technical Field

[0001] The present invention relates to a cultivation method of sophora japonica, in particular to a cultivation method of golden sophora japonica in karst mountains. Background Art

[0002] The area of karst rocky mountain areas is about 550,000 square kilometers. The soil here is mainly calcareous soil, with thin soil layers, poor water retention capacity and discontinuous distribution. The land in this area is severely degraded, with serious rocky desertification and fragile ecology.

[0003] Golden sophora japonica is a strain in the leguminous plant sophora japonica L., and is a deciduous tree. It is named because the sophora flower buds (usually referring to dry products) produced by it are golden yellow. Sophora flower buds can be used both as medicine and food, and are listed as top-grade in "Shennong's Herbal Classic". In folk, sophora flower buds are often used to treat enteritis bleeding, hemorrhoids bleeding, metrorrhagia and cardiovascular diseases, etc. It can also be used for cooking, steaming rice and making sophora flower bud tea, etc. The main component of sophora flower buds, rutin, has various functions such as antibacterial and anti-inflammatory, antiviral, reducing serum cholesterol, eliminating free radicals and antioxidant. As an important pharmaceutical ingredient and sunscreen and beauty additive, rutin is widely used in the pharmaceutical and daily chemical cosmetics industries.

[0004] Based on the need for producing sophora flower buds, golden sophora japonica has developed vigorously in the past two decades and has become an important agricultural (forestry) pillar industry in some areas. Its planting area in the northern Guangxi - southern Hunan region alone exceeds 350,000 mu. However, the existing golden sophora japonica is rarely planted in karst mountains. Occasionally, a small amount of golden sophora japonica planted in this type of mountain has problems such as low survival rate of field planting and low yield of sophora flower buds due to low cultivation and management techniques. Coupled with problems such as single planting and the golden sophora japonica losing all its leaves in autumn and winter, the rock and surface soil are completely exposed, and soil and water loss is serious, which further aggravates the ecological environment problems such as rocky desertification in karst rocky mountain areas. Golden sophora japonica itself is a relatively drought-tolerant economic plant. However, how to improve its cultivation technology in karst mountains so that farmers can obtain economic benefits from planting sophora while preventing and solving the rocky desertification in karst rocky mountain areas is an urgent problem for those skilled in the art. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a cultivation method of golden sophora japonica in karst mountains, aiming to obtain a method that can maximize the utilization of karst land resources, prevent rocky desertification in karst mountains, and increase the yield of sophora flower buds of golden sophora japonica.

[0006] To achieve the above object, the technical solution provided by the present invention is as follows:

[0007] A cultivation method of golden sophora japonica in karst mountains includes the following operation steps:

[0008] S1 Woodland Selection: In the karst rocky mountain area, select a plot with a leeward and sunny exposure, good drainage, and relatively deep soil as the planting site for Sophora japonica var. kimuraiana;

[0009] S2 Woodland Cleaning and Digging Planting Holes for Sophora japonica var. kimuraiana: In January - February of the solar calendar, remove weeds and miscellaneous shrubs in the woodland; for weeds and miscellaneous shrubs above rocks with a continuous area exceeding 5m 2 and without boulders exceeding 1m 2 in the rock - covered area, retain them, and remove the rest; after completing the woodland cleaning, dig planting holes for Sophora japonica var. kimuraiana (except where digging is impossible due to rocks occupying the relevant positions), and apply 8 - 10 kg of well - decomposed farmyard manure and 0.3 - 0.7 kg of ternary compound fertilizer to each planting hole;

[0010] S3 Planting of Sophora japonica var. kimuraiana: Conduct the planting of Sophora japonica var. kimuraiana on a rainy day in February - March of the solar calendar, using grafted seedlings with a basal diameter ≥ 1.2 cm as the planting seedlings for planting;

[0011] S4 Intercropping to Reduce Rock Exposure and Surface Soil Exposure in the Woodland and Prevent Soil Erosion:

[0012] S4.1 Planting Illicium difengpi: Conduct the planting simultaneously with Sophora japonica var. kimuraiana. Select the cracks or pits in the rocks as the planting points, and use seedlings ≥ 3 years old of Illicium difengpi as the planting seedlings for planting; after completing the planting, cover the tree - disk with stones to slow down the loss of root soil; Illicium difengpi is extremely drought - tolerant, barren - tolerant, and can grow on rocks;

[0013] S4.2 Planting Vicia villosa Roth: After completing the planting of Sophora japonica var. kimuraiana and Illicium difengpi, plow the woodland, with a plowing depth of about 35 cm. Apply 600 - 800 kg of well - decomposed farmyard manure per mu, incorporate the fertilizer into the soil during plowing, and break up the soil clods and level the soil; sow Vicia villosa Roth in early March of the solar calendar of the same year. Before sowing, soak the seeds in a 1000 - 1500 - fold solution of carbendazim suspension with an active ingredient content of 40% for 1 - 2 hours, then mix the seeds with an appropriate amount of sediment and broadcast them. The seeding rate per mu is 4 - 5 kg; Vicia villosa Roth is a drought - tolerant and semi - shade - tolerant perennial green manure plant as a herbaceous ground cover;

[0014] S4.3 Planting Calcium - loving Camellia nitidissima Plants: In the 4th year after the planting of Sophora japonica var. kimuraiana, that is, after Sophora japonica var. kimuraiana is initially closed, in January - February of the solar calendar of the same year, dig planting holes for calcium - loving Camellia nitidissima plants in the middle of every four adjacent Sophora japonica var. kimuraiana plants (except where digging is impossible due to rocks occupying the relevant positions), apply 4 - 5 kg of well - decomposed farmyard manure and 0.2 - 0.4 kg of ternary compound fertilizer to each planting hole, and then use cuttings ≥ 3 years old as the planting seedlings for planting;

[0015] S5 Field Management of Sophora japonica var. kimuraiana and Intercropped Plants.

[0016] Preferably, the calcium-loving Camellia plants in S4.3 are Camellia pubipetala and Camellia semiserrata. One or two of them are selected as evergreen shade-tolerant small shrubs for assisting in covering the exposed rocks and interplanted between the rows of Sophora japonica var. kuangsiensis.

[0017] Preferably, the field management of the Sophora japonica var. kuangsiensis and the interplanted plants in S5 is to carry out relevant management work according to the traditional field management requirements of the Sophora japonica var. kuangsiensis and each interplanted plant. At the same time, dwarfing treatment and auxiliary shading are carried out on the calcium-loving Camellia plants, and the harvests such as the flower buds of Sophora japonica var. kuangsiensis, the tea leaves and flowers of the calcium-loving Camellia plants, and the bark of Illicium difengpi are harvested.

[0018] Preferably, in S2, the planting pits for Sophora japonica var. kuangsiensis are dug at a plant spacing of about 3m×3m (except for the cases where the pits cannot be dug due to the occupation of relevant positions by rocks). The length×width×depth of the planting pits is 60cm×60cm×50cm.

[0019] Preferably, in S4.3, the planting pits for the calcium-loving Camellia plants are dug in the middle of every four adjacent Sophora japonica var. kuangsiensis plants (except for the cases where the pits cannot be dug due to the occupation of relevant positions by rocks). The length×width×depth of the planting pits is about 40cm×40cm×40cm.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Aiming at the problems in the prior art such as the low yield of the flower buds of Sophora japonica var. kuangsiensis, the exposure of mountain rocks and the ground surface, and soil erosion caused by the lack of planting technology of Sophora japonica var. kuangsiensis in karst mountains, the present invention establishes a three-dimensional compound planting mode of "Sophora japonica var. kuangsiensis + evergreen shrub (Illicium difengpi, calcium-loving Camellia plants) + herbaceous ground cover green manure (Vicia villosa)" by using precious medicinal materials or high-value economic plants with characteristics such as drought tolerance, barren tolerance, calcium-loving nature, and nitrogen fixation ability. Among them, the evergreen shrubs (Illicium difengpi, calcium-loving Camellia plants) play a role in covering the rock mass and reducing the exposure of rocks after the Sophora japonica var. kuangsiensis loses its leaves in autumn and winter; in addition to covering the exposed surface soil, the powerful fibrous (nodular) roots of the herbaceous ground cover green manure (Vicia villosa) can not only fix sand and maintain soil and water, but also fix nitrogen, and the decomposition of some of its plants into mud can increase the soil thickness and fertility, providing rich nutritional conditions for the growth of Sophora japonica var. kuangsiensis, thus being beneficial to improving the yield of the flower buds of Sophora japonica var. kuangsiensis and ultimately realizing the double improvement of ecological benefits and economic benefits.

[0071] Table 1 Effects of different cultivation methods on the survival rate of planting Sophora japonica var. kuangsiensis and interplanted plants, the yield of sophora flower buds in the 3rd and 4th years after planting, preventing soil erosion, and reducing the exposure of forest land rocks and surface soil

[0072]

[0073]

[0074] As can be seen from Table 1, the survival rate of transplanted Sophora japonica var. kuai in Example 1 was 96.21%, and the yields of sophora flower buds in the 3rd and 4th years after transplantation were 20.50 kg / mu and 39.63 kg / mu respectively, both higher than those of other comparative examples. It can be seen that the present invention has excellent effects in preventing soil erosion and reducing the exposure of rocks and surface soil in forest land. The present invention adopts a three-dimensional compound planting mode of "Sophora japonica var. kuai + evergreen shrub (Illicium difengpi, calcium-loving Camellia nitidissima) + herbaceous ground cover green manure (Vicia villosa Roth)", in which the evergreen shrub (Illicium difengpi, calcium-loving Camellia nitidissima) plays a role in covering the rock mass and reducing the rock exposure that occurs after the Sophora japonica var. kuai loses its leaves in autumn and winter. In addition to covering the exposed surface soil, the strong fibrous (nodular) roots of the herbaceous ground cover green manure (Vicia villosa Roth) can not only fix sand and conserve water and soil, but also fix nitrogen. After some of its plants die and turn into mud, it can increase the soil thickness and fertility, providing rich nutrient conditions for the growth of Sophora japonica var. kuai, thus being conducive to increasing the yield of sophora flower buds and ultimately realizing the double improvement of ecological and economic benefits.

[0075] As can be seen from Table 1, the survival rates of transplanted Sophora japonica var. kuai, Illicium difengpi and calcium-loving Camellia nitidissima in Comparative Example 1 were 79.82%, 63.92% and 56.45% respectively, which were significantly lower than the survival rates of the corresponding plants in other examples (Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4). Compared with Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4, in Comparative Example 1, seedlings without soil on their roots were used for transplantation, while in the others, bagged seedlings with soil on their roots were used, so the survival rate of transplantation in Comparative Example 1 decreased significantly.

[0076] The foregoing description of specific exemplary embodiments of the invention has been presented for purposes of illustration and example. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the above teaching.
