Temperature: Guava is not frost-resistant. The maintenance temperature must be controlled above 15 degrees for the plants to grow normally. Watering: If the annual rainfall is more than 1000 mm, there is no need to water. If the soil is always in In a drought state, it needs to be watered once a week; Fertilization: In addition to the base fertilizer mixed in the soil, it also needs to be topdressed once a month; Lighting: It prefers the sun and can accept sunlight all day long.

1. Maintenance methods

1. Temperature: If the temperature is below zero, the plants will freeze to death. Therefore, the curing temperature should be higher. The lowest curing temperature is 15 degrees. Plants will grow only when the temperature reaches 15 degrees. The optimal curing temperature is between 20 degrees and 28 degrees. Plants at this temperature will grow best. .

2. Watering: If it is not the dry season, there is no need to water. If the drought lasts for more than two months, it will need to be artificially hydrated, otherwise it will affect the yield. Observe before watering. Depending on the state of the soil, watering is only required when the soil is completely dry. Normally, watering is required once a week.

3. Fertilization: Fertilize it according to the method of applying thin fertilizer and heavy fertilizer. It is not suitable to apply thick fertilizer when fertilizing it. Heavy fertilizer will easily burn the roots. Fertilization can use compound fertilizers or human excrement, and the frequency of fertilization can be maintained once a month.

4. Light: Its growth is inseparable from light. Sufficient light is of great benefit to its growth, which can promote growth and increase yield. If full-day sunshine is not available, daily Lighting should be guaranteed for at least five hours.

2. Breeding skills

1. Reproduction: It can be reproduced by grafting. The propagation time is in winter and spring. When the seedlings grow to a diameter of 0.7 cm, they can be grafted. In the first half month of scion collection, pick the leaves and cut them off when the buds are about to germinate. The effect is best at this time. The rootstock is thicker, which means it has accumulated more nutrients, which is conducive to success. Generally, it is untied one month after the bud grafting. After the grafted buds have healed and survived, the rootstock will be cut off. After one year, it can be transplanted and planted.

2. Pruning: After the fruit harvest is completed, pruning is required. First, cut off the branches that are too lush; secondly, cut off the branches that are more than two centimeters; finally, cut off the general branches. Cut the branches shorter.

3. Problem Diagnosis

1. Insect pests: Aphids are its number one natural enemy. If found, they need to be treated with chlorpyrifos.

2. Diseases: Plants are more susceptible to canker and blight. If found, Bordeaux pulp can be used for spraying treatment.

4. Other issues

1. Edible: It is edible.

2. Other values: In addition to being eaten, it can also be used as medicine and has the function of stopping bleeding.
