Description

Technical Field

[0001] The invention relates to the technical field of transplanting and planting apricot seedlings, and in particular to a method for transplanting and planting apricot seedlings with high survival rate and rich selenium. Background Art

[0002] The transplanting and planting method of high-survival selenium-enriched apricot seedlings includes several key steps: First, select healthy and pest-free high-quality selenium-enriched apricot seedlings, and perform necessary pretreatments such as root pruning and disinfection. Second, select a suitable planting plot, plow, fertilize and disinfect the soil, and then plant according to a reasonable spacing between plants and rows to ensure that the roots are fully expanded and the soil around the roots is filled to keep the soil moist. After transplanting, timely watering, topdressing, pest control and weed cleaning are required to promote the growth and survival of seedlings.

[0003] Although this method can theoretically improve the survival rate of seedlings, it still has some defects in practical application. It has high requirements for environmental conditions, such as soil fertility, water management and climate, and any inappropriateness may lead to a decrease in survival rate. During the transplanting process, seedlings are easily affected by factors such as environmental changes and mechanical damage, which increases the uncertainty of survival rate. These factors have limited the large-scale promotion and application of this method to a certain extent. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a method for transplanting and planting selenium-rich apricot seedlings with a high survival rate, which solves the problem of high requirements for environmental conditions; during the transplanting process, seedlings are easily affected by factors such as environmental changes and mechanical damage, which increases the uncertainty of the survival rate.

[0005] To achieve the above objectives, the present invention is implemented through the following technical scheme: a method for transplanting and planting selenium-enriched apricot seedlings with a high survival rate, comprising:

[0006] S1. Select healthy and disease-free selenium-rich apricot seedlings, with a seedling height of 30-40 cm and a stem thickness of 0.5-0.8 cm;

[0007] S2. 1-2 days before transplanting the seedlings, perform root pruning to cut off damaged and overlong roots, with the pruning length being 1 / 3 of the total root length;

[0008] S3. Before transplanting, the roots of the seedlings are soaked in a solution containing 100 ppm indolebutyric acid rooting agent and 0.15% selenium fertilizer for 2-3 hours;

[0009] S4. Select a transplanting site that ensures the soil is rich in organic matter, with an organic matter content of no less than 2%, and has good drainage and a groundwater level below 1.5 meters;

[0010] S5. Dig a planting hole with a depth of 30 cm and a diameter of 40 cm at the transplanting site, apply 0.5-1 kg of decomposed organic fertilizer at the bottom of the hole, and add 10-20 g of selenium fertilizer as appropriate;

[0011] S6. When transplanting, spread the roots of the seedlings evenly and place them in the planting holes, making sure that the roots are fully in contact with the soil, backfill the soil, compact it lightly, and make sure that the root neck of the seedlings is 1-2 cm above the ground;

[0012] S7. After transplanting, water thoroughly with 1-2 liters of water per plant, and add 0.01-0.05% rooting agent to the water;

[0013] S8. Within 7 days after transplanting, water once in the morning and evening every day to keep the soil moist. Within one month after transplanting, apply thin liquid fertilizer every 7 days. The fertilizer contains the trace element selenium, 0.1-0.2 grams per plant each time. Within two months after transplanting, regularly check the growth of seedlings, replenish water in time, and prevent and control diseases and insect pests;

[0014] S9. After transplanting, regularly loosen the soil and weed once a month to keep the soil loose and promote root growth.

[0015] Preferably, the root pruning length is 1 / 3 of the total root length, and the root soaking time is 2-3 hours.

[0016] Preferably, the rooting agent is indolebutyric acid or naphthylacetic acid with a concentration of 100 ppm, and the concentration of selenium fertilizer in the soaking solution is 0.1-0.2%.

[0017] Preferably, the base fertilizer is decomposed organic fertilizer, and the usage amount is 0.5-1 kg per hole. The selenium fertilizer is sodium selenate or potassium selenate, and the usage amount is 10-20 grams per hole.

[0018] Preferably, the concentration of the rooting agent in the rooting water is 0.01-0.05%, and the amount of watering within 7 days after transplanting is 1-2 liters per plant each time.

[0019] Preferably, the preparation ratio of the thin liquid fertilizer is water: fertilizer = 100:1, and the added amount of the trace element selenium is 0.1-0.2 grams per plant each time.

[0020] Preferably, the height of the root neck of the seedling above the ground is between 1-2 cm, and the frequency of regular inspection of the growth of the seedling is once a week.

[0021] Preferably, the pest control adopts a cleaning method combining biological control and chemical control.

[0022] The present invention provides a method for transplanting and planting selenium-enriched apricot seedlings with a high survival rate. It has the following beneficial effects:

[0023] By selecting robust seedlings, root pruning and soaking treatment, the sensitivity of seedlings to the transplanting environment is reduced and the adaptability is improved. Root soaking treatment and appropriate root pruning make seedlings less susceptible to mechanical damage during transplanting. Through scientific fertilization and watering management, selenium-rich nutrition is provided to ensure the good growth state of seedlings after planting, greatly improving the survival rate. According to actual tests, the method of the present invention can increase the survival rate of selenium-enriched apricot seedlings to more than 90%. Continuous inspection and management after transplanting, including fertilization, watering, prevention and control of pests and diseases, and loosening and weeding, ensure the continuous and healthy growth of seedlings after planting. The method of combining biological control with chemical control reduces the use of chemical pesticides, protects the environment, and also ensures the healthy growth of seedlings.
