Temperature: guava is not frost resistant. The maintenance temperature should be controlled above 15 degrees before the plant can grow normally; Watering: if the annual rainfall is more than 1000mm, there is no need to water. If the soil has been in a dry state, it needs to be watered once a week; Fertilization: in addition to the base fertilizer mixed in the soil, it needs topdressing once a month; Light: it prefers sunshine and can accept all day sunshine.

1、 Curing method

1. Temperature: if the temperature is below zero, the plant will freeze to death. Therefore, the curing temperature should be higher. The lowest curing temperature is 15 degrees. It will grow only when the temperature reaches 15 degrees. The best curing temperature is between 20 degrees and 28 degrees. The plant growth state at this temperature is the best

2. Watering: if it's not a dry season, it doesn't need watering. If the continuous drought lasts for more than two months, it needs to be watered manually, otherwise it will affect the yield. When watering, first observe the state of the soil. Only when the soil is completely dry, it needs watering. Usually, it needs watering once a week

3. Fertilization: it should be fertilized according to the method of thin fertilizer and more fertilizer. It is not suitable for thick fertilizer, which is easy to burn roots. Fertilization can use compound fertilizer or human feces and urine. 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 it can't have all day sunshine, the daily light should be at least five hours

2、 Breeding skills

1. Reproduction: it can reproduce by grafting. The breeding time is in winter and spring. When the seedlings grow to 0.7 cm in diameter, 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 the best at this time. The rootstock is stronger, which indicates that there are more nutrients accumulated, which is conducive to success. Generally, it is unbound one month after budding, and the rootstock will be cut off after the budding is more synthetic and alive, and it can be transplanted and planted one year later

2. Pruning: pruning shall be carried out once after the fruit is harvested. First, cut off the branches that are too lush; Secondly, the branches more than two centimeters need to be cut off; Finally, cut the general branches short

3、 Problem diagnosis

1. Insect pest: aphid is its number one natural enemy. If found, it needs to be treated with chlorpyrifos

2. Disease: the plant is easy to be infected with canker and bacterial wilt. If found, Bordeaux pulp can be used for spraying treatment

4、 Other issues

1. Edible: it is edible

2. Other values: in addition to eating, it can also be used as medicine and has the function of hemostasis
