How to grow raspberries
To harvest plump and juicy raspberry fruits, it is crucial to master scientific cultivation methods. This berry plant, belonging to the Rosaceae Rubus genus, can be planted on a large scale in gardens or cultivated as an ornamental cash crop. This article will systematically analyze the five core elements of raspberry cultivation, from environmental control to pest and disease prevention.
Key points for raspberry environmental management
Temperature and lighting control
Raspberries have a very strong adaptability to the environment, with 15-20°C being the ideal growth temperature. They can tolerate low temperatures of -25°C in winter without any anti-freezing measures and can still grow normally at high temperatures of 35°C in summer. It is necessary to ensure 6 hours of direct sunlight per day, and planting in sunny areas can increase the sugar content of the fruits by 30%.
Water supply strategy
Keep the soil moisture at 60%-70% during the growing season, with the highest water requirement during the flowering to fruit expansion period. Using a drip irrigation system can save water by 40% and avoid leaf喷淋 induced gray mold disease. Attention should be paid to drainage during the rainy season, as积水 exceeding 48 hours can cause root rot.
Detailed explanation of raspberry propagation techniques
How to grow raspberries
Layering propagation operation
In mid-August, choose one-year-old healthy branches and use the wavy layering method. Bury the branches in a wave pattern in a 10cm deep trench, secure each wave peak with U-shaped wire, and independent plants can be formed after 60 days.
Key points of cutting propagation
In spring, select hard branches with a diameter of 0.8-1.2cm, cut 40cm cuttings, and soak the bases in a 1000ppm naphthalene acetic acid solution for 30 minutes. Plant the cuttings diagonally in sandy loam soil, maintain a ground temperature of 20-25°C, and they can take root in 30 days.
Raspberry disease control solutions
Stem rot control
It is prone to occur during the high temperature and humidity period of summer. When brown spots appear on the leaves at the initial stage, immediately apply a 50% carbendazim 800x solution to the roots, once a week for 3 weeks. Combined with the removal and incineration of diseased plants, it can effectively control the disease.
