1、 Curing method

1. Temperature: it likes to grow in warm places and is not resistant to cold. The minimum maintenance temperature can not be lower than 10 degrees. Plants will stop growing if it is lower than 10 degrees. The best maintenance temperature is between 15 degrees and 25 degrees. Plants in this temperature range have the best growth state

2. Watering: it needs to grow in water. There should always be water in the field from the clock arrangement to the seedling taking root, which is conducive to taking root. After the plant takes root, gradually deepen the water layer, and leave water surface on the upper part of the plant. If the temperature drops to zero, you need to deepen the water layer to between 40cm and 60cm, leaving only a few leaf tips on the water surface

3. Fertilization: its growth consumes a lot of nutrients. After 15 days of successful planting, it needs to start topdressing. Topdressing is applied three times in total, with an interval of 15 days. In September, it is preferred to use secondary potassium chloride, which can increase the weight of the stem

4. Light: it needs enough sunshine for its growth. It can be guaranteed to have five hours of light every day. The light cannot be too strong. If it is too strong, it will affect the quality of the plant

2、 Breeding skills

1. Propagation: propagation of water celery requires asexual propagation of seed stems. In August, the seed stems should be harvested from the reserved fields, and the plants with a horizontal diameter of about one centimeter at the base should be selected for germination. Its germination temperature is 25 degrees. Therefore, it is best to select the place with back sun and ventilation for germination, and remove the top of the selected seed stems. Then tie it into a round bundle with a diameter of 30 cm, and cover it with a layer of fresh grass to ensure humidity. I'm playing. Pour cold water on it. In about ten days, they will take root and can be planted when the temperature drops below 30 degrees in August

2. Pruning: after 20 days of planting, the plant should be pruned and the branches that are not growing well can be removed

3、 Problem diagnosis

1. Insect pests: aphids and Pieris rapae are the main pests during its growth period. At the end of September, we should pay attention to insect inspection and pest control, because this time is a high incidence period of insect pests, and we need to use quick killing emulsion for spraying treatment

2. Disease: if the leaves of the plant are dry, it is mostly caused by insufficient fertilization, so the amount of fertilizer needs to be increased

4、 Other issues

1. Toxicity: non toxic

2. Edible: edible
