Description

Technical Field

[0001] This invention relates to the field of plant fertilization technology, specifically to a comprehensive fertilization method for promoting the rapid growth of Podocarpus macrophyllus. Background Technology

[0002] Podocarpus macrophyllus is a common ornamental tree species found in areas south of the Yangtze River. When shaped, its branches often twist and turn, resembling a dragon ascending to its full height, symbolizing longevity and wealth, making it popular among garden enthusiasts. Cultivating shaped Podocarpus macrophyllus is an important means to further enhance its value and promote the development of its industry. However, the natural growth rate of Podocarpus macrophyllus is relatively slow, resulting in a long cultivation period for each shaped tree.

[0003] Promoting rapid growth of Podocarpus macrophyllus through fertilization techniques is key to accelerating the cultivation of shaped Podocarpus macrophyllus. Short-acting fertilizers (such as compound fertilizers) can quickly provide the nutrients needed by plants, but their effects are unstable and can easily lead to nutrient excess or deficiency. Long-acting fertilizers (such as organic fertilizers like chicken manure) can provide the nutrients needed by plants for a long time, but their release rate is slower.

[0004] Therefore, it is necessary to provide a comprehensive fertilization method to promote the rapid growth of Podocarpus macrophyllus and solve the problem that existing fertilization techniques are insufficient to promote the rapid growth of Podocarpus macrophyllus. Summary of the Invention

[0005] The purpose of this invention is to provide a comprehensive fertilization method to promote the rapid growth of Podocarpus macrophyllus, and the specific technical solution is as follows:

[0006] A comprehensive fertilization method to promote rapid growth of Podocarpus macrophyllus includes:

[0007] Step S1: Before planting Podocarpus macrophyllus, determine the amount of fertilizer, the depth of the planting hole, and the condition that the diameter of the planting hole is larger than the diameter of the root ball of Podocarpus macrophyllus based on the diameter of the root ball.

[0008] Step S2: Mix the fertilizer combination that meets the fertilization amount with the soil excavated from the planting hole to form soil fertilizer; when planting Podocarpus macrophyllus, use soil fertilizer to bury the root ball of Podocarpus macrophyllus in the planting hole.

[0009] Step S3: During the growth period of Podocarpus macrophyllus, use a combination of short-acting and long-acting fertilizers to promote rapid growth of Podocarpus macrophyllus.

[0010] Optionally, the long-acting fertilizer includes rapeseed cake and well-rotted chicken manure; the short-acting fertilizer includes compound fertilizer.

[0011] Optionally, in step S1, when the diameter at ground level of the Podocarpus macrophyllus is less than or equal to 10cm, the depth of the planting hole is 20-30cm, the diameter of the planting hole is 30-50cm larger than the diameter of the root ball of the Podocarpus macrophyllus, and the amount of fertilizer applied is 1.25-1.75kg of short-acting fertilizer and 0.75-1.25kg of rapeseed cake.

[0012] When the diameter at ground level of Podocarpus macrophyllus is greater than 10cm but less than 20cm, the planting hole depth should be 30-40cm, and the diameter of the planting hole should be 50-70cm larger than the diameter of the root ball of Podocarpus macrophyllus. The amount of fertilizer applied should be 4.5-5.5kg of short-acting fertilizer and 2.25-2.75kg of rapeseed cake.

[0013] When the diameter at ground level of Podocarpus macrophyllus is greater than or equal to 20cm, the planting hole depth should be 40-50cm, and the diameter of the planting hole should be 50-70cm larger than the diameter of the root ball of Podocarpus macrophyllus. The amount of fertilizer applied should be 9-11kg of short-acting fertilizer and 4.5-5.5kg of rapeseed cake.

[0014] Optionally, in step S2, when the diameter at ground level of the Podocarpus macrophyllus is greater than 10cm, after using soil fertilizer to bury the root ball of the Podocarpus macrophyllus in the planting hole, it is necessary to pile soil on top of the soil fertilizer; the soil used in the pile should be loose soil; after piling the soil, the root ball of the Podocarpus macrophyllus needs to be thoroughly watered once.

[0015] Optionally, in step S2, when the diameter at ground level of the Podocarpus macrophyllus is greater than 10cm, before burying the root ball of the Podocarpus macrophyllus in the planting hole with soil and fertilizer, it is also necessary to set up a fence around the root ball of the Podocarpus macrophyllus; the fence is set to fit against the inner wall of the planting hole.

[0016] Optionally, in step S3, before the Podocarpus macrophyllus sprouts in spring, a short-acting fertilizer is used to supplement the nutrients for the growth of the Podocarpus macrophyllus. The short-acting fertilizer is applied once every half month, and the amount applied each time is determined according to the size of the diameter of the Podocarpus macrophyllus.

[0017] After the Podocarpus macrophyllus sprouts in spring, while using the same short-acting fertilizer, rapeseed cake is sprinkled under the Podocarpus macrophyllus tree. The rapeseed cake is applied every 10-15 days, and the amount applied each time is determined according to the diameter of the Podocarpus macrophyllus. The rapeseed cake seeps into the soil in the root zone of the Podocarpus macrophyllus with rainwater or irrigation water and is absorbed and utilized by the root zone of the Podocarpus macrophyllus.

[0018] Optionally, in step S3, after the Podocarpus macrophyllus sprouts in spring, when the diameter at ground level of the Podocarpus macrophyllus is greater than or equal to 20cm, the amount of short-acting fertilizer applied each time is 0.75-1.25kg, and the amount of rapeseed cake applied each time is 0.75-1.25kg.

[0019] When the diameter at ground level of Podocarpus macrophyllus is less than 20cm, the amount of short-acting fertilizer applied each time is 0.25-0.75kg, and the amount of rapeseed cake applied each time is 0.25-0.75kg.

[0020] Optionally, in step S3, when the Podocarpus macrophyllus is in summer and autumn, the long-acting fertilizer combination uses rapeseed cake and chicken manure;

[0021] When using rapeseed cake, it needs to be soaked in water and fermented to form fermented fertilizer. The fermentation conditions are as follows: the mass ratio of rapeseed cake to water is 1:5-1:10, sealed for fermentation, and the fermentation time is greater than or equal to 15 days. When the diameter at which the Podocarpus macrophyllus is greater than or equal to 20cm, the amount of fermented fertilizer applied each time is 2.5-3kg, and it should be applied once every half month. When the diameter at which the Podocarpus macrophyllus is less than 20cm, the amount of fermented fertilizer applied each time is 0.75-1.25kg, and it should be applied once every half month.

[0022] When using chicken manure, pack 25-30 kg of chicken manure into a fiber bag and make small holes in the fiber bag for releasing the chicken manure. Place the fiber bag containing chicken manure on the ground of the target area, which is the ring-shaped area enclosed between the fence and the root ball of the Podocarpus macrophyllus. Before sunrise each day, water the area with the chicken manure and let it seep into the soil where the root zone of the Podocarpus macrophyllus is located, where it will be absorbed and utilized by the root zone of the Podocarpus macrophyllus.

[0023] In step S3, when the Podocarpus macrophyllus is in winter, fermented fertilizer is applied once a month.

[0024] Optionally, in step S3, when the Podocarpus macrophyllus is in summer and autumn, if it does not rain for 7-10 consecutive days or the root zone is not thoroughly wetted by rainwater, the Podocarpus macrophyllus needs to be thoroughly watered once.

[0025] When the growing season of Podocarpus macrophyllus is in winter, if there is no rain for a period of time or the rainwater does not thoroughly wet the root zone, it needs to be watered thoroughly once every 8-12 days.

[0026] Optionally, the comprehensive fertilization method for promoting rapid growth of Podocarpus macrophyllus also includes regular testing of the growth status of Podocarpus macrophyllus and the soil in the root zone. If the test results are not up to standard, the amount of fertilizer applied during the corresponding season of the growth period of Podocarpus macrophyllus is increased; if the test results exceed the standard, the amount of fertilizer applied during the corresponding season of the growth period of Podocarpus macrophyllus is reduced.

[0027] The application of the technical solution of the present invention has at least the following beneficial effects:

[0028] This invention employs a comprehensive fertilization method to promote the rapid growth of Podocarpus macrophyllus. Through steps S1-S3, the combined use of short-acting and long-acting fertilizers provides optimal fertilization efficiency, promotes rapid growth, shortens the cultivation cycle, enhances the value and industrial development of Podocarpus macrophyllus, and is both practical and economical. Specifically, this comprehensive fertilization method can increase the average annual radial growth of Podocarpus macrophyllus with a diameter at birth (DBH) of 2-9 cm to 1-1.5 cm, and the average annual radial growth of Podocarpus macrophyllus with a DBH of 10 cm or more to 2-3 cm. In contrast, conventional fertilization methods are very slow in increasing the average annual radial growth of Podocarpus macrophyllus, generally only increasing it to 0.3-0.5 cm for those with a DBH of 2-9 cm and 0.6-1 cm for those with a DBH of 10 cm or more. Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.

[0030] A comprehensive fertilization method to promote rapid growth of Podocarpus macrophyllus includes:

[0031] Step S1: Before planting Podocarpus macrophyllus, determine the amount of fertilizer, the depth of the planting hole, and the condition that the diameter of the planting hole is larger than the diameter of the root ball of Podocarpus macrophyllus based on the diameter of the root ball.

[0032] Step S2: Mix the fertilizer composition that meets the fertilization amount with the soil excavated from the planting hole to form soil fertilizer; when planting Podocarpus macrophyllus, use soil fertilizer to bury the root ball of Podocarpus macrophyllus in the planting hole.

[0033] Step S3: During the growth period of Podocarpus macrophyllus, use a combination of short-acting and long-acting fertilizers to promote rapid growth of Podocarpus macrophyllus.

[0034] The long-acting fertilizer includes rapeseed cake and well-rotted chicken manure, which contain slow-release organic nutrients and can provide comprehensive nutrients for Podocarpus macrophyllus; the short-acting fertilizer includes compound fertilizer, which should be buried in the soil or dissolved in water when applied.

[0035] In step S1, when the diameter of the Podocarpus macrophyllus is less than or equal to 10cm, the depth of the planting hole is 20-30cm, the diameter of the planting hole is 30-50cm larger than the diameter of the root ball of the Podocarpus macrophyllus, and the amount of fertilizer is 1.5kg of short-acting fertilizer (specifically compound fertilizer) and 1kg of rapeseed cake.

[0036] When the diameter of the Podocarpus macrophyllus is greater than 10cm but less than 20cm, the planting hole depth is 30-40cm, the diameter of the planting hole is 50-70cm larger than the diameter of the root ball of the Podocarpus macrophyllus, and the amount of fertilizer is 5kg of short-acting fertilizer (specifically phosphate fertilizer) and 5 jin of rapeseed cake.

[0037] When the diameter of the Podocarpus macrophyllus is greater than or equal to 20cm, the planting hole depth should be 40-50cm, and the diameter of the planting hole should be 50-70cm larger than the diameter of the root ball of the Podocarpus macrophyllus. The amount of fertilizer applied is 20 catties of short-acting fertilizer (specifically phosphate fertilizer) and 10 catties of rapeseed cake.

[0038] In step S2, when the diameter at ground level of the Podocarpus macrophyllus is greater than 10cm, after burying the root ball of the Podocarpus macrophyllus in the planting hole with soil and fertilizer (specifically, the soil and fertilizer need to cover more than the top surface of the root ball), it is also necessary to pile soil on top of the soil and fertilizer; the soil used in the pile should be loose soil with good air permeability and not easy to compact (and no fertilizer should be added); after piling the soil, the root ball of the Podocarpus macrophyllus needs to be thoroughly watered once.

[0039] In step S2, when the diameter at ground level of the Podocarpus macrophyllus is greater than 10cm, before burying the root ball of the Podocarpus macrophyllus in the planting hole with soil fertilizer, it is also necessary to set up a fence around the root ball of the Podocarpus macrophyllus. The fence is set to fit against the inner wall of the planting hole, so as to fix the fertilizer and irrigation area within the fence and improve the absorption effect of fertilizer and water by the root zone of the Podocarpus macrophyllus.

[0040] In step S3, before the Podocarpus macrophyllus sprouts in spring, a short-acting fertilizer is used to supplement the nutrients for its growth. The short-acting fertilizer is applied once every half month, and the amount applied each time is determined according to the diameter of the Podocarpus macrophyllus.

[0041] After the Podocarpus macrophyllus sprouts in spring, while maintaining the use of short-acting fertilizer, apply rapeseed cake under the tree every two weeks, with the amount determined by the diameter of the tree's trunk. The rapeseed cake will seep into the soil around the root zone of the Podocarpus macrophyllus with rainwater (such as rain during the spring rainy season) or irrigation water and be absorbed and utilized by the root zone. During the spring growing season, the frequency of irrigation should be determined based on rainfall; specifically, if there is no continuous rain, the Podocarpus macrophyllus needs to be thoroughly watered every 7-10 days.

[0042] In step S3, after the Podocarpus macrophyllus sprouts in spring, when the diameter at ground level of the Podocarpus macrophyllus is greater than or equal to 20cm, the amount of short-acting fertilizer (specifically containing N, P2O5 and K2O, with a mass ratio of 16:16:16, having a high concentration of essential elements such as nitrogen, phosphorus and potassium, wherein nitrogen fertilizer promotes the growth of Podocarpus macrophyllus leaves, phosphorus fertilizer promotes the growth of the root zone of Podocarpus macrophyllus, and potassium fertilizer promotes the growth of Podocarpus macrophyllus branches and trunks) is 1kg each time, and the amount of rapeseed cake is 1kg each time.

[0043] When the diameter of the Podocarpus macrophyllus is less than 20cm, the amount of short-acting fertilizer (specifically containing N, P2O5 and K2O, with a mass ratio of 16:16:16, and having a high concentration of essential elements such as nitrogen, phosphorus and potassium) should be applied each time, and the amount of rapeseed cake should be applied each time.

[0044] In step S3, when the Podocarpus macrophyllus is in summer and autumn, the slow-release fertilizer combination uses rapeseed cake and chicken manure;

[0045] When using rapeseed cake, it needs to be soaked in water and fermented to form fermented fertilizer. The fermentation conditions are a rapeseed cake to water mass ratio of 1:6, sealed fermentation, and a fermentation time of 15 days. When the diameter at which the Podocarpus macrophyllus is greater than or equal to 20cm, the amount of fermented fertilizer applied each time is 2.75kg, and it should be applied once every half month. When the diameter at which the Podocarpus macrophyllus is less than 20cm, the amount of fermented fertilizer applied each time is 1kg, and it should be applied once every half month.

[0046] When using chicken manure, 27 kg of well-rotted chicken manure is placed in a fiber bag, and small holes are made in the fiber bag for releasing the chicken manure. The fiber bag containing the well-rotted chicken manure is placed on the ground in the target area, which is the ring-shaped area enclosed between the fence and the root ball of the Podocarpus macrophyllus. Before sunrise each day, the chicken manure is watered and slowly dissolved and seeps into the soil where the root zone of the Podocarpus macrophyllus is located, which takes 2-3 hours and is absorbed and utilized by the root zone of the Podocarpus macrophyllus for a long time.

[0047] In step S3, when the Podocarpus macrophyllus is in winter, fermented fertilizer is applied once a month.

[0048] In step S3, when the Podocarpus macrophyllus is in summer and autumn, if there is no rain for a period of time or the rainwater does not soak the root zone, the Podocarpus macrophyllus needs to be watered thoroughly once a week.

[0049] When the growing season of Podocarpus macrophyllus is in winter, if there is no rain for a period of time or the rainwater does not soak the root zone, it needs to be watered thoroughly once every 10 days.

[0050] The comprehensive fertilization method for promoting rapid growth of Podocarpus macrophyllus also includes regular testing of the growth status of the Podocarpus macrophyllus and the soil in the root zone. If the test results are not up to standard, the amount of fertilizer applied during the corresponding season of the Podocarpus macrophyllus' growth period will be increased. If the germination rate is significantly low, the amount of compound fertilizer applied at one time will be appropriately increased. If the test results exceed the standard, the amount of fertilizer applied during the corresponding season of the Podocarpus macrophyllus' growth period will be reduced. If root burn is found, the amount of slow-release fertilizer applied will be reduced.

[0051] This invention selected two Podocarpus nurseries in the red soil region of southern China as experimental bases, designated as Base 1 and Base 2, respectively. In Base 1, the Podocarpus planting experiments of Example 1 and Comparative Example 1 were conducted; in Base 2, the Podocarpus planting experiments of Example 2 and Comparative Example 2 were conducted.

[0052] Example 1:

[0054] Comparative Example 1:

[0055] At Base 1, compared to Example 1, only short-acting fertilizer was used to plant 50 Podocarpus macrophyllus trees with a diameter at 3 cm.

[0056] Example 2:

[0057] At Base 2, the present invention employs the comprehensive fertilization method described above to promote the rapid growth of Podocarpus macrophyllus to plant 20 Podocarpus macrophyllus trees with a diameter at breast height of 12 cm.

[0058] Comparative Example 2:

[0059] At Base 2, compared to Example 2, only 20 Podocarpus macrophyllus trees with a diameter at 12 cm were planted using short-acting fertilizer.

[0060] The average increase in diameter at ground level of all Podocarpus macrocarpus planted in Examples 1-2 and Comparative Examples 1-2 from the second to the third year after planting was statistically analyzed, as shown in Table 1.

[0061] Table 1 shows the average increase in diameter at ground level from the second to the third year after planting of Podocarpus macrophyllus in Examples 1-2 and Comparative Examples 1-2.

[0062] Serial Number Average increase in diameter at breast height (cm) Example 1 1.5 Example 2 3 Comparative Example 1 0.5 Comparative Example 2 1
