Abstract:
Ercai is a very nutritious green vegetable, widely popular in southern China. However, planting Ercai also requires attention to timing and techniques, which will be detailed in this article.
I: Choosing the Right Planting Season
Ercai grows relatively fast, so it is more suitable for planting in seasons with higher temperatures. Generally, spring, autumn, and winter are good times to plant Ercai. Summer temperatures are too high and not suitable for planting.
II: Considering Geographical Location and Altitude
Ercai has relatively strict requirements for its growing environment. Generally, mountainous areas and plains with an altitude not exceeding 1000 meters are the most suitable places for Ercai to grow. These factors should be considered when choosing a planting location.
III: Ensure the Soil is Fertile
Ercai has high requirements for soil fertility. Fertilize the land before planting and keep the soil moist. Ercai does not like acidic soil, so it needs to be neutralized before planting.
IV: Suitable Planting Density
Ercai does not require a large planting area. The planting density is about 10-12 plants per square meter, leaving 3-4 leaves on each plant.
V: Maintain Suitable Temperature and Humidity
Ercai needs suitable temperature and humidity to grow well. Generally, a temperature of around 20°C and a relative humidity of around 70% are appropriate.
VI: Scientific Watering
Ercai has a large demand for water, but it cannot be overwatered. Generally, water in the morning or evening to ensure the soil moisture is around 60%.
VII: Pay Attention to Pest Control
Ercai is susceptible to pests, especially aphids and whiteflies. During the planting period, it is necessary to spray pesticides regularly to prevent pest infestations.
VIII: Timely Weeding
Ercai grows relatively fast, but it is also easily affected by weeds. During the planting period, it is necessary to weed regularly to ensure that Ercai can grow smoothly.
IX: Regular Pruning
Ercai grows relatively fast and will continuously produce new branches. At this time, timely pruning is required. Pruning can promote the branching of Ercai, thereby increasing the yield.
X: Reasonable Fertilization
Ercai has a high demand for nutrients, so timely fertilization is required during the planting period. It is recommended to use a combination of organic and chemical fertilizers.
XI: Timely Harvesting
The growth period of Ercai is relatively short, about 30-35 days. Therefore, once Ercai matures, it should be harvested in time to prevent it from becoming overripe or too old, which would affect its taste.
XII: Control Diseases
Ercai is susceptible to diseases such as brown spot and damping-off. During the planting period, it is necessary to strengthen prevention and control work and pay attention to the occurrence of diseases.
XIII: Suitable Intercropping for Ercai
Ercai can be intercropped with other vegetables, such as potatoes, eggplants, and peppers. This can make full use of land resources and increase farmers' income.
XIV: Suitable Cooking Methods for Ercai
Ercai can be eaten raw or stir-fried. It has a crisp and refreshing taste and is rich in nutrients. It is recommended to use less oil and salt when eating to reduce the burden on the body.

The above are the best times and techniques for planting Ercai. I hope this can help the majority of farmers grow healthy and delicious Ercai.
