Black布林 Breeding Methods and Precautions
Known as the 'Plum Queen', Black布林 offers a unique flavor and high nutritional value, making it a new favorite in orchards. Mastering scientific planting techniques can not only improve fruit quality but also achieve continuous high yields. This article will systematically explain the full-cycle management plan for Black布林, from environmental control to disease prevention and treatment.
Black布林 Planting Environment Management
Precise Temperature and Humidity Control
As a temperate fruit, Black布林 thrives best at a stable temperature range of 18-22℃. In the spring germination period, ensure a daily average temperature of ≥10℃, and controlling the flowering period temperature between 15-25℃ can improve the fruit setting rate. In the northern regions, it is recommended to use a combination of windbreak forests and plastic mulch for double insulation.
Light Intensity and Duration
The daily light duration should not be less than 6 hours, with at least 8 hours during the fruit expansion period. Use the 'Happy Shape' pruning method to ensure the inner branches have a light transmission rate >30%. In high-density plantations, maintain a row spacing of 3-3.5 meters and a plant spacing of 2-2.5 meters.
Black布林 Water and Fertilizer Management Techniques
Smart Irrigation Solutions
Irrigate 15-20mm per week during the germination period, increasing to 25mm during the hard core period. Using a drip irrigation system can save 40% of water, combined with soil moisture sensors for precise water control. After top dressing, immediately water thoroughly to promote nutrient penetration to the 30cm deep root layer.
Nutrient Ratio Plan
In the young tree stage, N:P:K should be mixed in a ratio of 2:1:1, and for fruit-bearing trees, adjust to 1:2:2. After harvesting, spray 0.3% phosphorus acid potassium + 0.2% boric acid solution on the leaves every 10 days for 3 times, which can improve the cold resistance ability by 30%.
Black布林 Pruning and Propagation
Key Points for Tree Shape Formation
After planting, retain 3-4 main branches, and when the main stem reaches 50cm, pinch it in time. Use the 'Three Branch Renewal Method': retain 1/3 fruiting branches, 1/3 nutrient branches, and 1/3 reserve branches each year to achieve continuous high yields.
Black布林 Breeding Methods and Precautions
Efficient Seedling Raising Techniques
Choose grafted seedlings, with the rootstock of wild cherry to improve resistance. Plant in spring when the daily average temperature is stable at 10℃, and complete planting in autumn 40 days before frost. Set up an 8:1 pollination tree ratio, using varieties like 'St. Rose' to increase the fruit setting rate by 25%.
Common Black布林 Issues and Solutions
Physiological Disease Prevention and Treatment
Yellow leaves and defoliation are often caused by magnesium deficiency, apply 10kg of magnesium sulfate per mu and spray 0.2% on the leaves. For the early stage of root rot, use a 3000-fold solution of metalaxyl, and in severe cases, cut the diseased roots and disinfect with 5% lime water.
Fruit Management Key Points
Keep a fruit spacing of 8-10cm during thinning, and spray mancozeb before bagging to prevent diseases. Controlling water 20 days before harvesting can increase the sugar content by 2-3 degrees, and the best harvest period is when the fruit skin turns to a purple-black color.
Through systematic environmental control and meticulous management, Black布林 planting can enter the high-yield period in 3 years, with an output of 2000-3000kg per mu. It is recommended to establish a growth log, record key phenological data, and optimize the management plan based on local climatic characteristics to achieve a dual improvement in quality and yield.
