How does an eggplant grow?
The editor will share with you the small knowledge of how eggplants grow and the illustration of the growth process of eggplants. Please see the detailed introduction below.
1. Characteristics of each growth and development stage of eggplants
(1) The germination period is from the absorption of water by the seeds to the appearance of the first true leaf, about 20 days. Seed germination first requires sufficient water absorption. Generally, dry seeds are soaked for about 8 hours, and under suitable temperature conditions, the radicle extends from the seed germination hole after 5-6 days, and can then be sown in the seedbed. During this period, higher temperature and humidity should be provided, and after the seedlings emerge, they should be exposed to sufficient light to prevent excessive growth.
(2) The seedling stage is from the appearance of the first true leaf to the appearance of the bud, about 50-60 days. During the seedling stage, the vegetative growth and the differentiation of reproductive organs occur simultaneously. Before the 4th leaf stage of the seedlings, it is mainly vegetative growth, and the flower bud differentiation begins at the 3rd to 4th leaf stage. After the true leaf cruciform stage (4 leaves stage), the growth rate of the seedlings increases significantly, and 95% of the growth is completed in this stage. Based on this characteristic of seedling growth, seedlings should be transplanted before the true leaf cruciform stage (2-3 leaves stage) during seedling raising. The day temperature should be around 25°C, and the night temperature should be maintained at 15-20°C. If the temperature in the greenhouse is lower than 10-15°C for a long time, it will severely affect the differentiation of flower buds.
(3) The flowering and fruiting stage begins after the first bud appears on the eggplant. The fruiting habit of eggplants is quite regular, which is related to the branching of eggplants. Each branching results in a layer of fruit. The order of fruit appearance is called the door, opposite茄子, four gates, eight winds, and full sky stars, with a geometric progression in the number of flowers. The first three layers of branching and fruit distribution are relatively accurate, while the later ones may have irregular fruit distribution due to the uneven nutrition of each branch. It takes about 18-25 days for the fruit to go from flowering to setting and to maturation, and another 30-40 days for the seeds to mature.
The harvest range of eggplants is large. According to the growth state of the plants, the fruit can be picked earlier or later to adjust the relationship between reproductive growth and vegetative growth. If the plant growth is poor, in addition to strengthening fertilization and watering, the fruit can be picked earlier, or even the underdeveloped young fruits can be removed to concentrate nutrients for the growth of branches and leaves, providing good conditions for the development of fruits in the next stage. Conversely, if the plant growth is too vigorous, the fruit can be picked later to inhibit vegetative growth and promote reproductive growth. In the growth cycle of eggplants, the appearance of the first bud is a transitional stage between vegetative growth and reproductive growth. During this period, vegetative growth dominates, and the key point in production management is to pay attention to controlling the supply of water and fertilizer to prevent excessive water and fertilizer from causing flower and fruit drop, which affects early yield. After the "eye" stage of the first eggplant, vegetative growth gradually weakens, and reproductive growth gradually strengthens. The nutrient distribution of the plant has shifted to fruit growth as the center. At this time, the fruit and the growing point, as well as the lower fruit and the upper fruit, compete with each other for nutrients. Sufficient water and fertilizer should be supplied to the plant, and technical measures such as pruning and harvesting should be taken to maintain the balance between vegetative growth and reproductive growth.
