Abstract
Description
Technical Field
[0001] The invention relates to a method for efficiently increasing the yield of gardenia jasminoides fruit. Background Art
[0002] Yellow Gardenia is a plant resource for both medicinal and edible purposes. It has white flowers and yellow fruits, and has many flowers and fruits. It is an important bulk Chinese medicinal material and an important floral fragrance plant. It is widely used in landscaping and environmental fragrance. In recent years, the price of yellow Gardenia fruit has continued to rise. In 2023, the price of fresh Gardenia fruit was as high as 10 yuan / kg, and in 2024 it reached 20-30 yuan / kg. In 2024, farmers in Fuding City, Fujian Province planted Fenguan No. 1 Gardenia and harvested benefits per mu between 15,000 and 20,000 yuan. Therefore, cultivating and harvesting Gardenia fruit has become a golden fruit for farmers to get rich. With improved varieties, there is no other way for farmers to increase production and income except to study fertilization to increase its yield; but the long-term and large-scale application of chemical fertilizers also causes soil compaction and serious root-knot nematodes, leading to plant root degradation, reduced root absorption capacity, and runoff pollution caused by excessive application of N, P, and K fertilizers. How to get rid of the method of continuously increasing the application of chemical fertilizers to promote high yields. The inventor has found through long-term research that indoleacetic acid has a certain effect on promoting flowering and fruiting, but improper application can also cause serious yield reductions. How to increase fruit yield and promote high fruit yield without increasing the application of fertilizers has become a technical problem that needs to be overcome urgently in production, and a problem that needs to be solved urgently for the current efficient and sustainable development of Gardenia jasminoides. Summary of the invention
[0003] The invention aims to provide a method for efficiently increasing the yield of gardenia jasminoides fruit, which is a new method for increasing the yield of gardenia jasminoides cultivation.
[0004] The object of the present invention is to achieve the following: a method for efficiently increasing the yield of gardenia jasminoides fruit, comprising spraying 25.00-125.00 mg·L of -1 Indoleacetic acid is used to promote fruit yield, with a spraying rate of 50-100 mL per plant, once every 7 days, for a total of 2 times.
[0005] The above method for efficiently increasing the yield of Gardenia jasminoides fruit is sprayed with 75.00 mg·L -1 Indoleacetic acid is the preferred concentration. The spraying rate for 4-6 year old stands is 50 mL per plant each time, spray once every 7 days, for a total of 2 times; the spraying rate for stands over 7 years old is 100 mL per plant each time, spray once every 7 days, for a total of 2 times.
[0006] The above-mentioned method for efficiently increasing the yield of gardenia fruit comprises applying biochar, urea, superphosphate and potassium sulfate fertilizers. For plants aged 4 to 6 years, 22.50-40.00 g of biochar, 25.24-51.00 g of urea, 26.72-54.00 g of phosphate fertilizer and 16.14-32.02 g of potassium fertilizer are applied to each plant; biochar is applied after harvest in winter, urea, superphosphate and potassium sulfate are applied when spraying indoleacetic acid, and various fertilizers are mixed and applied in a circular ditch at the drip line of the crown when applying. For closed forest stands, the fertilizers can be applied in the ditch between two rows of trees, and the ditch application depth is 20-30 cm; for forest stands aged 7 years or more, 40.0-60.0 g of biochar, 51.0-75.0 g of urea, 54.0-81.0 g of superphosphate and 32.0-64.0 g of potassium sulfate are applied to each plant according to the tree body and site conditions. g. The application method is the same as that of 4-6 year old forest stands; plants that are applied with urea, superphosphate and potassium sulfate according to this formula do not need to be applied with other fertilizers.
[0007] The above-mentioned method for increasing the yield of Gardenia jasminoides fruit was adopted, and the fruit yield was generally increased, with the increase range of 27.19-92.51%. Spraying 75.00 mg·L -1 Indoleacetic acid has the highest fruit yield and harvest efficiency. The application of the inventive method of the present invention can not only increase the fruit yield, but also the flower yield increase of 15.25-48.58%. Calculated at 20 yuan per kilogram of flowers in 2024, the income per mu of flowers can be increased by more than 3,000 yuan. In the method of the present invention, biochar is first applied, which is beneficial to improve the soil microenvironment at the application site, promote the renewal growth of fine roots, enhance the ability to resist soil compaction and root-knot nematodes, and then improve the absorption capacity of the plant root system, promote the growth of plants, and increase the yield of flowers and fruits; at the same time, the formula fertilization of the present invention reduces the amount of chemical fertilizers used and improves the fertilizer efficiency. Therefore, the application of the method of the present invention not only promotes the increase in fruit and flower yields, but also solves the problems of soil compaction, root-knot nematodes, and runoff pollution caused by the long-term and large-scale application of chemical fertilizers, and excessive application of N, P, and K fertilizers. It has multiple benefits, obvious innovation, and extremely significant application effects, which is of great significance.
