The farmer's farmland is a good example of the key to strong seedlings. The cultivation of any vegetable is the key. The seedlings are good, not only have fewer pests and diseases but also increase yield. Strong seedlings are the most productive and stable. A key step. How to judge the standard of eggplant seedlings?
First, from a morphological point of view
1. The root system is developing normally, and there is no bad root. The root is mainly white root.
2. Thick petiole, wide leaves, no curl, no lesions
3. The length of the short nodule of the seedling stem section is uniform with the plant height. Stems have good toughness and wind resistance.
4. Solanum should be bud, 6 leaves, 9 leaves or 12 leaves.
Second, from a physiological point of view
High physiological activity, high concentration of cell fluid, normal metabolism, and low water absorption.
Eggplant strong seedling cultivation:
1, the choice of seedbed
To cultivate eggplant seedlings, you must choose a leeward sun, a high dry terrain, good drainage, close to the field, convenient management, and no place in the past two years.
2. Preparation of culture soil
The bed soil for cultivating eggplant seedlings must be fertile, rich in all necessary nutrients, suitable for pH, strong water holding capacity and good ventilation.
3, seed sowing
The suitable sowing period for winter and spring cultivation is from September to December.
4, seed treatment
In order to promote emergence and prevent disease, eggplant must be seeded before planting. Its contents mainly include breaking dormancy, drying at high temperature, soaking seeds in warm soup, disinfecting chemicals and germination.
Combined with the above, the standard of eggplant strong seedlings is specifically: there are 5,6 sheets and the height of the seedlings is about 15 cm, the leaves are large and thick, the embryos are short and thick, the leaves are dark green, the stems are 0.4 cm thick and the seedling height is about 3 cm. Eggplant is a crop that is afraid of heat and frost, and most of the eggplants in China are planted in the open field. Eggplant seeding can only be carried out in the frost-free period, that is, it can only be cultivated in the open field in spring and summer, while the frost-free period in China's climatic conditions is very short, which is bound to produce high yield of eggplant, which is a crop that is more affected by climate. .
