Cultivation methods and precautions of Sichuan pepper

1. Maintenance methods

1. Temperature: It is not cold-resistant. The lowest temperature for wintering is five degrees Celsius. If the temperature is below five degrees, the plant will be frostbitten, which will affect the fruit-bearing rate next year. Therefore, if planting in the north, anti-freeze measures need to be taken in winter. The maintenance temperature should be kept between 18 and 30 degrees.

2. Watering: Its main growth period is in summer. Water evaporates quickly in summer, so watering should be frequent. It is best to water it once every two days. It should be noted that the soil must be watered thoroughly each time you water it.

3. Fertilization: When fertilizing before flowering, nitrogen fertilizer is generally used as the main fertilizer. The purpose is to promote growth and supplement the lack of nutrition in the previous autumn and winter. When fertilizing after flowering, the fruit set rate should be considered. In addition to nitrogen fertilizer, phosphorus and potassium fertilizers should also be used. Top dressing can be done once a month.

4. Light: Long-day plants have a particularly high demand for light. Therefore, when providing them with light, there is no need to consider strong light or scattered light. You only need to consider the light time. The daily light time cannot be less than eight hours.

2. Breeding techniques

1. Whitewashing the tree trunks: Before winter, you can whitewash the tree trunks with a trunk whitewash agent. This will directly kill the overwintering pathogens and some insect eggs on the trunks, and also prevent night freezes.

2. Pruning: Before winter, proper pruning is needed. The pruning targets are mainly one- to two-year-old branches. The purpose of this is to reduce the tree's consumption of nutrients, improve its ability to resist cold, and ensure that it can survive the winter smoothly.

3. Problem Diagnosis

1. Pests: The pepper plant is more susceptible to the cotton aphid, which will attach itself to the tender leaves to suck the juice, causing the branches and leaves to curl up and resulting in the plant dropping flowers and fruits. To treat this pest, it is necessary to spray it with a 40 percent dilution of omethoate, with the spraying interval being once every ten days.

2. Disease: Yellowing and falling leaves on the plant are probably caused by improper watering. Although the plant likes moist soil, if improper watering causes water accumulation in the soil, the roots of the plant cannot breathe and root rot will occur. From the appearance, these are symptoms of yellowing and falling leaves. To solve this problem, you need to temporarily stop watering. Only water the branches and leaves of the plant each time, but do not water the roots. After the soil at the roots is completely dry, you can water it normally.

IV. Other issues

1. Edibility: It can be eaten, and more often it is made into a condiment.

2. Is it suitable for indoor cultivation: It is not suitable for indoor cultivation because its plant body is relatively large and prone to insects, so it is not recommended for home cultivation.
