Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, and in particular to a planting method for adjusting the production period of wax apples. Background Technology

[0002] wax apple( SyzygiumsamarangenseMerr.&Perry Rose apple (also known as wax apple or golden apple) is a tropical evergreen tree native to Malaysia and India. It has a beautiful shape, lush foliage, and typically flowers in summer and bears fruit in autumn. Its fruit is brightly colored, of good quality, and rich in nutrients.

[0003] Under natural conditions, the wax apple harvest season is mainly concentrated in summer. However, because the fruit produced during the peak season is small, bland in flavor, of poor quality, and does not store well, and coincides with the peak season for other tropical fruits such as lychee, longan, and mango, its economic value has long been overlooked. Harvest season regulation involves using artificial cultivation methods or chemical treatments to suppress the plant's vegetative growth, promote flower bud differentiation, and then induce the differentiated flower buds to bloom and develop into fruit, allowing the plant to bear fruit in a season when it would not normally produce fruit. Currently, wax apple harvest season regulation techniques mainly employ cultivation methods such as girdling and root pruning to suppress vegetative growth, increase the carbon-nitrogen ratio, and induce flower bud differentiation, followed by the use of flowering inducing agents (mainly organophosphorus pesticides such as propiconazole and chlorpyrifos). Generally, root pruning can suppress growth in a short period. However, when temperature, moisture, and fertilizer conditions are suitable, the injured roots will heal quickly and grow a large number of new roots at the break point, so the effect is not lasting. Girdling is an artificial cutting of the bark of fruit trees to block the transport function of the phloem sieve tubes and affect the transport of organic nutrients produced by photosynthesis in the leaves to the roots, thereby controlling the plant's vegetative growth. However, it requires high technical skills, and improper application can lead to tree death. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a planting method for adjusting the production period of wax apples by means of topdressing, adding flowering promoters, and thinning flowers and fruits. The method has a long-lasting effect and produces wax apples of good quality and excellent taste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a planting method for adjusting the production period of wax apples, comprising the following steps:

[0006] S1. Pruning: Pruning should be carried out 65 days before the flowering period of wax apples. The main pruning is to thin out the upper layer of the canopy of vigorous branches, and remove dead branches, drooping branches, crossing branches, weak branches and overly dense branches. After the pruning is completed, the whole garden is sprayed with a fungicide.

[0007] S2. Dig fertilization pits: Dig a fertilization pit around each wax apple tree, with the pit being 33 cm wide and 17 cm deep;

[0008] S3. Apply base fertilizer: Add 0.5 kg of calcium magnesium phosphate fertilizer and 2 kg of nitrogen and potassium compound fertilizer to the fertilizer pit as base fertilizer, with an interval of 14 days between each application, for a total of 2 applications.

[0009] S4. Heart-drenching treatment 1: On the 10th to 15th day after the completion of the base fertilizer application, use a mixture of 20-30% sodium silicate aqueous solution and 10-25 mg / L shikimic acid solution in equal volume ratio to drench the heart 1-3 times, with a dosage of 400-500 mL per plant and an interval of 15-20 days between each application.

[0010] S5. Heart-drenching treatment 2: 7 to 15 days after the completion of step S4, use a mixture of 10 to 30 mg / L citrulline and 0.05 to 0.10% EDTA calcium sodium sodium aqueous solution in equal volume ratio for heart-drenching. The dosage is 100 to 200 mL per plant, with an interval of 7 to 10 days between each application, for a total of 1 to 3 applications.

[0011] S6. Foliar fertilizer application: During the heart-drenching treatment in step S5, apply fertilizer to the leaves. The foliar fertilizer is made by mixing 10-15 parts potassium chlorate, 8-15 parts brown sugar, 8-15 parts chitosan oligosaccharide peptide calcium, 1-5 parts dimethylformamide, and 80-100 parts tap water by weight. Spray until the leaves drip water. Repeat every 7-10 days for a total of 1-3 times.

[0012] S7. Inducing flowering: 15 to 20 days after the completion of step S6, choose a sunny morning or evening and apply 15 to 20 mL of 0.5 to 1 g / L dimethyl sulfoxide to each plant 1 to 3 times.

[0013] S8. Pruning and artificial pollination: Prune off any messy branches without flower buds during the growth process, manually unscrew the calyx of the wax apple flower, and attach the anther to the stigma of the pistil.

[0014] S9. Flower thinning: 3 to 5 weeks after pollination, thin the flowers of the wax apple flower, select the small flowers with good growth in each flower spike, and remove the middle and upward flower spikes and keep the flower spikes on both sides, with each flower spike spaced 15 to 20 cm apart.

[0015] S10. Fruit thinning: After the wax apples have grown fruit, thin them out, leaving 3 to 5 fruits on each bunch and cutting off the excess wax apples.

[0016] Furthermore, step S1, pruning, is performed 70 days before flowering. Pruning can improve the situation of poor ventilation and insufficient light penetration caused by the shady canopy, and promote photosynthesis in leaves at different levels. The fungicide is 80% mancozeb wettable powder diluted 600 times, with a dosage of 80 mL per plant.

[0017] Furthermore, the calcium magnesium phosphate fertilizer was purchased from Shandong Xinyuhang Fine Chemical Co., Ltd., with a total phosphorus content ≥12%; the nitrogen and potassium compound fertilizer was purchased from Shandong Chengshun Chemical Technology Co., Ltd.

[0018] Furthermore, in step S4, on the 12th day after the completion of the basal fertilizer application, the heart of the plant is irrigated twice with a mixture of 22% sodium silicate aqueous solution and 22 mg / L shikimic acid solution in equal proportions, with a dosage of 450 mL per plant and an interval of 18 days between each application.

[0019] Furthermore, in steps S4 and S5, "filling the core" refers to adding fertilizer along the fertilization pit.

[0020] Furthermore, in step S5, on the 10th day after step S4 is completed, the heart of the plant is irrigated with a mixture of 25 mg / L citrulline and 0.08% EDTA calcium sodium water in equal volume ratio, with a dosage of 150 mL per plant, and the interval between each application is 8 days, for a total of 2 applications.

[0021] Further, in step S6, the foliar fertilizer is composed of 12 parts potassium chlorate, 12 parts brown sugar, 12 parts chitosan oligosaccharide peptide calcium, 2 parts dimethylformamide, and 90 parts tap water by weight. It is sprayed onto the leaves until they drip, with an interval of 8 days between each application, for a total of 2 applications.

[0022] Furthermore, in step S7, 18 days later, the heart is irrigated twice with 18 mL of 0.8 g / L dimethyl sulfoxide per plant.

[0023] Furthermore, in step S9, four weeks after pollination, the flowers of the wax apple are thinned, with each flower spike spaced 16 cm apart.

[0024] Furthermore, in step S10, leave 4 fruits on each bunch and cut off the excess wax apple fruits;

[0025] Compared with the prior art, the beneficial effects of the present invention are: the present invention provides a planting method for adjusting the production period of wax apples.

[0026] The planting method for adjusting the production period of wax apples in this invention can effectively increase the number of wax apple flower spikes, far exceeding that of traditional planting methods, and the flowering rate can reach over 98%. The use of sodium silicate aqueous solution promotes the transport of amino acids, auxins, and inorganic salts to the treated areas, thus promoting flower bud differentiation and providing the silicon element needed for wax apple growth. Two irrigations at the base of the wax apple tree provide the necessary nutrients for growth, promoting rapid tree growth. Foliar fertilization inhibits vegetative growth and promotes flower bud differentiation, solving the key technical difficulties in regulating the production period of wax apples. Furthermore, after flower induction, the wax apples exhibit the advantage of uniform flower spike germination. Detailed Implementation

[0117] S4. Apply base fertilizer: Add 0.5 kg of calcium magnesium phosphate fertilizer and 2 kg of nitrogen and potassium compound fertilizer to the fertilizer pit as base fertilizer, with an interval of 14 days between each application, for a total of 2 applications.

[0118] S5. Pruning and artificial pollination: Prune off any messy branches without flower buds during the growth process, manually unscrew the calyx of the wax apple flower, and attach the anther to the stigma of the pistil.

[0119] S6. Flower thinning: Four weeks after pollination, thin the flowers of the wax apple flower, selecting the small flowers with good growth on each flower spike. The principle is to remove the middle and upward flower spikes and keep the flower spikes on both sides, with each flower spike spaced 16cm apart.

[0120] S7. Fruit thinning: After the wax apples have grown fruit, thin them out, leaving 4 fruits on each bunch and cutting off the excess wax apples.

[0121] Comparative Example 6

[0122] The specific steps for using the existing girdling treatment method are as follows:

[0123] S1. Pruning: Pruning should be carried out 65 days before the flowering period of wax apple. The main pruning is to thin out the upper layer of the canopy and remove dead, drooping, crossing, weak and overly dense branches. After the pruning is completed, the whole garden should be sprayed with a fungicide of 80% mancozeb wettable powder at a dilution of 600 times, with a dosage of 80 mL per plant.

[0124] S2. Two to three weeks after step S1, make two to three ring marks on the base of the trunk, 30cm from the ground. The width of the ring marks should be adjusted between 2 and 2.5 depending on the vigor of the tree.

[0125] S3. Dig fertilization pits: Dig a fertilization pit around each wax apple tree. The fertilization pit should be 33 cm wide and 17 cm deep.

[0126] S4. Apply base fertilizer: Add 0.5 kg of calcium magnesium phosphate fertilizer and 2 kg of nitrogen and potassium compound fertilizer to the fertilizer pit as base fertilizer, with an interval of 14 days between each application, for a total of 2 applications.

[0127] S5. Pruning and artificial pollination: Prune off any messy branches without flower buds during the growth process, manually unscrew the calyx of the wax apple flower, and attach the anther to the stigma of the pistil.

[0128] S6. Flower thinning: Four weeks after pollination, thin the flowers of the wax apple flower, selecting the small flowers with good growth on each flower spike. The principle is to remove the middle and upward flower spikes and keep the flower spikes on both sides, with each flower spike spaced 16cm apart.

[0129] S7. Fruit thinning: After the wax apples have grown fruit, thin them out, leaving 4 fruits on each bunch and cutting off the excess wax apples.

[0130] Experimental Example 1: Number of flower spikes and flowering rate

[0131] At the wax apple planting base in Sanya, Hainan, nine plots were divided, each with the same area and number of wax apple plants. The first to third plots correspond to Examples 1 to 3 of this invention, and the fourth to ninth plots correspond to Comparative Examples 1 to 6. Each plot was planted with 25 wax apple plants. The number of flower spikes and the flowering rate were calculated as the average of the number of flower spikes and the percentage of flowering branches within a 1-meter square in the central part of each wax apple plant in different directions (east, west, south, and north). Flowering rate (%) = number of flower spikes / (flower spikes + flower buds).

[0132] This experiment records a comparison of the number of flower spikes and the flowering rate obtained by the present invention and the comparative example. The results are detailed in Table 1.

[0133]

[0134] As shown in Table 1, the planting method for adjusting the production period of wax apples in this invention can effectively increase the number of wax apple flower spikes, far exceeding that of traditional planting methods, and the flowering rate can reach over 98%, with uniform flower spike germination. Comparative Examples 1-3 show that wax apple flowering can only be promoted when sodium silicate aqueous solution + shikimic acid solution, citrulline + calcium sodium EDTA aqueous solution, potassium chlorate + brown sugar + chitosan oligosaccharide peptide calcium + dimethylformamide react with each other, possibly due to insufficient nutrition, resulting in some flower buds failing to transform into flower spikes. Comparative Example 4 shows that dimethyl sulfoxide is more effective than ethephon in promoting the growth of wax apple flower spikes. Comparative Examples 5 and 6 have fewer flower spikes, with flowering rates of 58.5% and 57.9%, respectively. It is speculated that improper root pruning and girdling operations may have resulted in insufficient nutrient transport to the wax apple trees, preventing them from transitioning from vegetative growth to reproductive growth. Applying fertilizer in stages three times according to the scheme of this application can increase the number of wax apple flower spikes and the flowering rate, thereby increasing the yield of wax apples.

[0135] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
