Many vegetable farmers are used to choosing older or large seedlings when planting vegetables. This is actually a misunderstanding.
Most vegetable farmers think that the price of vegetables will be higher the sooner they are on the market, so many vegetable farmers prepare the seedlings early in order to grab time, but wait until the seedlings are very old (8-10 true leaves) before planting. Although the planting of large seedlings can bring the first fruit to market early, it is not easy to cultivate strong trees, and the later yield is low, which does more harm than good. that is because:
One is that large seedlings are not conducive to the differentiation of flower buds in the middle and late stages of vegetables. The differentiation of flower buds of most vegetables starts when 2 to 3 true leaves are unfolded. By the time of branching (6 to 7 true leaves), the differentiation of flower buds has reached the "gypsophila" stage, which determines the yield and quality of vegetables. Critical period. If the plants are not colonized during this period, the plants are already 25-30 cm high, and the seedlings on the seedling bed are crowded and shading each other, which will affect the progress of photosynthesis and easily cause the seedlings to grow longer, which will inevitably affect the differentiation of flower buds in the middle and late stages, leading to the yield of vegetables in the middle and late stages. Greatly reduced.
The second is slow planting of large seedlings and serious root diseases. Planting large seedlings reduces the photosynthesis of the plant, produces less photosynthetic products, and the root system does not get sufficient nutrients and grows too slowly. The root system grows too slowly, and the water and nutrients absorbed from the soil are not enough to supply the growth and development needs of the stems, leaves and flowers above the ground, so the slow seedling time is long.
The third is that the growth of the root system of large seedlings is weak due to inadequate nutrient growth, resulting in weak plant resistance to diseases. Some soil-borne diseases will take the opportunity to infect and cause vegetable death. After planting, small seedlings with 4 to 6 leaves can quickly adapt to the soil environment and take roots, which is conducive to slowing the seedlings and has enough nutrient growth space to make the plants strong.
