How to Care for海棠果
As a special fruit tree with both ornamental and edible value,海棠果 is deeply loved by horticulture enthusiasts for its lustrous red fruits and elegant flower posture. However, to successfully cultivate a海棠果 tree with abundant fruits, it is necessary to master scientific management methods. This article will systematically analyze the six key elements of海棠果 cultivation, from environmental control to daily maintenance.
1. Environmental Control for海棠果 Growth
Accurate Temperature Control
The optimal growth temperature range for海棠果 is 25-35°C. In northern regions, special attention should be paid: double-layer cold-proof greenhouses need to be built in winter, and plastic mulch should be used in spring to increase soil temperature, ensuring that root temperature does not fall below 10°C. When the air temperature is below 15°C, the plant will show growth stagnation.
Scientific Light Management
During the flowering and fruiting period, 6-8 hours of direct sunlight are required daily. It is recommended to plant in a north-south direction. In summer, use a 50% shading net from 11 am to 2 pm to prevent sunburn while ensuring sufficient scattered light. In winter, supplementary lights can be used to extend the lighting to 10 hours.
2. Water and Fertilizer Management
Optimization of Irrigation System
Use a drip irrigation system to maintain soil moisture at 60-70%, and dig 30cm deep drainage ditches during the rainy season. Key points need to be watered: 2L per plant daily during the budding period, increased to 3L per plant during the fruit expansion period, along with the addition of 0.2% potassium dihydrogen phosphate foliar fertilizer.
Precision Nutrient Supply
Base fertilizer: use decomposed sheep manure (5kg/hole) + calcium superphosphate (200g). Top dressing plan: apply nitrogen fertilizer (urea 50g/plant) during the germination period, increase phosphorus and potassium fertilizers (compound fertilizer 100g/plant) during the flower bud differentiation period, and apply organic fertilizer (3kg/plant) after fruit harvesting.
3.海棠果 Propagation Management
Seed Selection and Treatment
Select plump autumn fruit seeds, stratify in sand for 120 days, and soak in 50°C warm water for 24 hours. Sow at a depth of 2-3cm, maintaining a row spacing of 80cm×100cm. After seedlings emerge, spray 0.1% borax solution monthly to promote root development.
