First, why not water more  　　 1. Frequent watering will make the soil temperature unstable and low, which is not conducive to the root growth of vegetable seedlings. It is not suitable for hair roots, roots are few, roots are shallow, stems are weak, and the requirements of deep roots and strong seedlings are not reached. . 2. Too much watering is easy to cause low temperature roots. The ground temperature is lower than 12 °C and the duration is longer, which causes the growth and development of seedlings to be blocked. If the duration is long, the roots will not be new roots, no root hairs, and the root skin will rot after rusting. The upper part of the ground appears to be wilting, and finally the seedlings die and die. 3. Due to the poor growth of the roots of the vegetable seedlings, the weak stems, the poor ability to absorb water and nutrients, the disease resistance and insect resistance are weakened, the infection is easy and pests and diseases occur, and the cultivation requirements are not met.  Second, how to properly water  　　 1. Before planting the seedlings, the bottom water should be poured to ensure the water demand of the seedlings. The ridge surface is covered with a film to allow the ground temperature to rise and stabilize, and the seedlings are planted. 2. When planting the seedlings, the seedling water should be poured, but the slow seedling water should not be flooded with water. It is recommended to pour the nest water ( watering in the planting hole ) or drip irrigation in the root of the vegetable seedlings to make the roots of the vegetable seedlings and the soil well combined. 3. The seedling period is generally not watered, and the vegetables are promoted and then poured (the pepper has a pepper, the eggplant has a stalk, the tomato has the first fruit, and the melon has a bottom melon ) . 4. If the soil is too dry, it is necessary to water the growth of the vegetable seedlings. It must be hydrated by shallow watering or drip irrigation. Do not flood the water, so that the soil temperature is greatly reduced. 5. After the vegetables start to produce results, the demand for water and nutrients increases. At this time, the roots of the vegetables have grown and developed, and the ability to withstand adverse environments is enhanced. According to the requirements of different vegetables for water and nutrients, watering and topdressing are normal.
