Celery planting: what should summer celery seedlings pay attention to?

What should summer celery seedling pay attention to? Please give a detailed introduction and guidance on the characteristics of celery, which likes cold and cool, cold and afraid of heat. June to July coincides with high temperature, high humidity and strong light weather, and it is difficult for celery to sprout in high temperature weather, coupled with the harm of insect pests, especially aphids and underground worms. It is easy to lack seedlings and die trees. If you want to plant good celery seedlings, you should pay attention to the following points: first, pay attention to control the budding temperature in summer due to the high external temperature, it is difficult to sprout, you can take measures according to local conditions. The ambient temperature of sprouting is controlled at 15 to 20 degrees Celsius, and it can germinate after about 10 days. Second, the prevention of continuous cropping or soil consolidation is often caused by two reasons: on the one hand, the soil quality of the bed soil is not good; on the other hand, there is insufficient bottom water and low humus content. Therefore, it is necessary to choose the land with loose and fertile soil and rich in soil organic matter to build the seedbed. Third, too much nitrogen fertilizer is used scientifically, resulting in only growing seedlings, thin leaves and light colors, and few roots. When the temperature is too high, the respiration of seedlings is enhanced, which consumes a lot of nutrients, and it is easy to appear weak seedlings, resulting in dead seedlings. Fourth, sunshade and rain protection in summer, the environment of high temperature, strong light and heavy rain is not conducive to celery emergence, so it is necessary to shade the sun and prevent rain to raise seedlings. Pay attention to the control of underground pests in order to control mole cricket and other underground pests, stir-fry the wheat bran in a pot, add 90% trichlorfon powder and mix well to make poison bait, sprinkle around the seedbed. 6. Strengthening the management of seedling stage generally, the temperature of seedling bed should be controlled at 15 ℃-20 ℃ after sowing, the relative humidity of soil should be kept at about 85%, and the seedlings can be ready in 8-10 days. After finishing the seedlings, the double seedlings were removed first, the second seedling was carried out 10 days later, the seedling spacing was 1-1.5cm, and the seedling spacing was 5cm after one month. The seedlings could be transplanted separately according to the plant spacing of 5cm, and the seedlings could be effectively saved by watering after planting. It is necessary to keep the soil moist and suitable temperature and light environment at the seedling stage.
