Breeding method and time of eggplant

The breeding methods of eggplant are as follows: select high-quality varieties with disease resistance, storage and transportation, purchase good seedling equipment, then soak the seeds to accelerate germination, control the temperature and humidity at the seedling stage, select strong seedlings 60-80 days after emergence, and enhance heat preservation measures. pay attention to prevent the occurrence of rigid seedlings and old seedlings, to prevent diseases such as seedling quenching. The time of raising eggplant seedlings: generally 80-90 days before planting, the specific time of planting depends on the ground temperature and cultivation environment.

First, the breeding time of eggplant

In order to determine the seedling time of eggplant, the planting time is generally determined according to the cultivation environment and ground temperature, and then 80-90 days is calculated according to the planting time. Generally, when planting in early spring, where the ground temperature is 10 centimeters, it can be planted at more than 13 degrees Celsius. If the greenhouse is produced with sunlight, the general ground temperature should reach more than 15 degrees Celsius, and the temperature above 20 degrees Celsius can be planted.

2. The method of raising eggplant seedlings

1. Select varieties

Varieties that are resistant to low temperature, weak light, disease, storage and transportation are generally selected.

2. Nursery equipment

Greenhouse and other equipment can be used, and insect control measures and sunshade measures should be provided in summer and autumn.

3. Sowing seeds

Eggplant seed coat is thick, need to soak seeds to promote budding, and this process takes a long time. If it is summer and autumn, you can directly use sterilized seeds to sow. After configuring the bed soil and medicinal soil, it can be watered and sown. Generally, before sowing, the soil should be watered thoroughly with warm water, then sprinkled with medicinal soil, and covered with plastic film after sowing. If sowing in winter and spring should be covered with plastic film, sowing in summer and autumn should be covered with straw, when most of the seedlings top soil, the mulch needs to be removed.

4. Seedling stage management

In the seedling stage, the temperature and humidity should be well controlled. if the bed soil is wet, the temperature and humidity should be reduced immediately after slowing down the seedling. It is convenient to use the nutrition bowl to divide the seedling, and the temperature and light should be managed after the seedling is divided. General seedbed watering should not be too dry or too wet, generally sufficient organic fertilizer, do not need topdressing, in the week before planting, to reduce the temperature and humidity, in order to refine seedlings.

5. Strong seedling standard

Generally speaking, strong seedlings can be selected after 60-80 days. At this time, the seedlings can grow to about 15 cm and have 7-9 true leaves. The leaves are qualified in shape and color, and the stems, flowers and roots are growing well. The whole seedling is free from diseases and insect pests and damage.

6. Disease control

Disease control includes anti-freezing, preventing stiff seedlings and old seedlings, and preventing seedling collapse disease. In order to prevent and cure these diseases, it is generally necessary to enhance the heat preservation effect, and the varieties resistant to low temperature should be selected, heating measures can also be selected, or thermal insulation measures such as small arch shed should be covered. In addition, the management of water and temperature should be strengthened, the water and soil temperature should be controlled as far as possible in the seedling stage and seedling stage, the diseased seedlings should be detected and treated as early as possible, and the seedbed should be disinfected with medicine soil.
