1, land selection and orchard construction. Guava is a plant that likes high temperature and light very much. Weak light, no light, no growth. The growth temperature of guava should not be lower than 19, and the highest temperature should not be higher than 39. The most suitable temperature for its growth is around 26℃, so the places where guava is planted are generally in the tropics. To build guava orchards, we should choose places that are sunny and leeward, with no or little frost. Guava can grow well in any soil, so the requirements for soil are not high. Although there is no high requirement, in order to get better income, we should choose fertile soil, soft soil and heavy acidic soil, and the PH value should be less than 6.

2. Selection of seeds. In recent years, the planting benefit of guava is very good, and there are many guava seedlings on the market, most of which are of poor quality. Therefore, we should go to the seedling company or scientific research unit to buy seedlings, so as to choose better seedlings. Usually the way to raise seedlings is grafting, because it takes a long time to raise seedlings with seeds. Pay attention to the grafting part when selecting seedlings to see if the grafting part develops well up and down. If they are all good, we should choose such seedlings, and at the same time choose seed seedlings with good growth, thick leaves and no disease.

3. Sowing method. Usually, guava is planted in the beginning of spring. Pay attention to the distance between each seedling when planting, otherwise it will hinder the growth of guava. Usually, their distance is about 4*4 meters. Before planting, the planting pit should be dug. The average width and length of the pit are 100cm and the height is about 80cm. Then, mix the farmyard manure with the soil and put it in the into the pit. Another thing to note is that when planting, the roots should not touch the fertilizer, then lightly step on the pit, water it, cover the grass, and the tree tray is about 26cm from the ground.

4. Orchard management. Guava has a long fruiting period. Although it takes a long time, its yield is very good, so it needs a lot of nutrition. When adding fertilizer, organic fertilizer should be added at least twice a year. Depending on the situation of the tree, adding trace fertilizer to it properly can make its fruit quality better. One more thing, guava can blossom and bear fruit all year round. When it is short of water, it should be irrigated in time, at least once a week, and then drained in time when there is too much rain.
