Management of planting virgin fruit in greenhouse in winter

The main results are as follows: 1. The winter weather is cold, so the seeds of virgin fruit should be soaked in warm water, and then placed at 27 ℃ to accelerate germination. After the seeds are whitened and mixed with new high-fat film, the seeds can be planted, which can greatly improve the seed emergence rate and isolate the infection of bacteria. After planting the virgin fruit, it is necessary to adjust the light, temperature and humidity in the greenhouse in time to make the virgin fruit grow well and the plant is strong.

2. during the growth period, according to the needs of plant growth, reasonable watering and fertilization, balanced application of nitrogen, phosphorus and potassium fertilizer to ensure sufficient nutrients for plant growth. The virgin fruit grows rapidly in the greenhouse, and the plant is tall and upright. When the plant grows to 30-40 cm, it should be pulled by a rod or cable in time to prevent lodging. In addition, Huawang No. 3 was sprayed to force a large amount of exuberant nutrition from the top and tip of the plant, and the main nutrition of the plant was transferred to the young fruit development system, so as to enhance the fruit expansion vitality, avoid leaf hypertrophy and improve field permeability.

3. The common diseases of virgin fruit are bacterial wilt, blight and so on. In greenhouse cultivation, attention should be paid to strengthening ventilation management in order to reduce the humidity in the greenhouse and reduce the breeding of bacteria. And timely inspection, found symptoms of the disease in time to take targeted measures for prevention and control of the disease. Achieve timely harvest to ensure high yield and high quality of virgin fruit.
