1. All the weeds, trees or other unhealthy objects, stones, etc. in the planned area of ​​Qingti shall be cleared to facilitate the reclamation. 2. Open up the land or plunge the land slightly before reclaiming at a gentle slope below 5°C. Then according to the requirements of the spacing of the rows, dig 0.8-1m in length, width and depth. When digging, topsoil and bottom soil are stacked separately. Hill slopes with slopes of 5-12 degrees. 3. Gully and fertilization. Gully 1-2 months before planting. First apply the topsoil to the lowest level, then weeds, leaves and leaves 0.3 kg of lime mixed, and then return. A layer of topsoil, pond mud, waste soil compost 30 kg and 0.2 kg of phosphate fertilizer, and then back to cover a layer of earth and soil filled to the ground 20 cm, into the mixed livestock manure 10-15 kg, calcium , Magnesium, phosphate fertilizer 1.0 kilograms, compound fertilizer 0.2 kilograms, plus back ground mix and fill, and finally cover a layer of 10 centimeters of soil. In this way, after about 20 days of submergence, you can start planting. (IV) Planting 1. Selection of elite varieties for selection of the main cultivars should not only fully consider the quality of the fruits, but also consider its high yield performance and stress resistance. Judging from the current comparison of domestic varieties, the twentieth century pearl guava selected by Taiwan has high yield and good product performance and is suitable for large-scale planting. The guava in the new century is currently the most widely cultivated variety in Taiwan. The branches are relatively vertical, and the leaves are long and oval, thick and short in internodes. The fruit has a long oval shape with an average fruit weight of 310-450 grams. The meat is crisp, meticulous and has a good flavor. The thickness of flesh is 1.3-2.5 cm, the edible rate of the fruit is 77%-85%, the sugar content is high, about 8.0-13.0Birix, and the quality is excellent. The pearl guava has a longer branch and longer twigs. The tree is more evacuated. The fruit is round to oval. The fruit is 7.2-12.4 cm long, and the fruit diameter is 6.0-8.0 cm. The fruit is large and the average fruit weight is 500-520 g. , not easy to soften, few and soft seeds, good flavor. High sugar content, about 8-14 Birix, excellent quality. 2. Planting density and time Planting time Spring, summer and autumn are all available, but spring is preferred. After the spring planting, the temperature is getting higher, the rain is getting more and more cloudy, the lighting is not strong, the management is easy, the survival rate is high, and the growth is fast. Compared with the summer and autumn colonization, the shoots are abundant and the accumulation of nutrients is more conducive to wintering. Summer plant has high temperature, evaporation, large transpiration and poor survival. The autumn plant grows slowly and the buds are not mature and they are overwintering. But now generally promote the nutrition bag seedlings to be planted by the artificial planting, so the summer and autumn planting, also has little effect, only need to strengthen the management. Plant spacing can be determined according to the soil fertility and management level of the garden, and fertile soil in the garden can be appropriately reclaimed; however, dense planting requires a higher level of strokes. The general spacing is 3-4 meters and the row spacing is 4-6 meters. Foreign countries are generally used to sparsely planting, and they mostly use 6 meters by 9 meters. However, in order to strive for early high-yield crops and implement twig cultivation, the strong-cutting cultivation can recover 2.5 x 2.5 meters or 2 meters x 3 meters.
