1. The latitude limit for planting figs in gardens is 40 north latitude, and it is not suitable to build gardens in areas where the winter temperature is lower than-15℃. It is advisable to choose a place with the lee and the sun to build a garden and avoid waterlogging and depression. Before the garden is built, the soil should be deeply ploughed, and 2000-3000 kg of soil miscellaneous fertilizer should be applied per mu. When you build a garden, you should choose excellent varieties and strong seedlings and plant them in shallow pits. The planting time is better from the end of March to the beginning of April, and it can be extended to the middle of April in Jiaodong area. The planting density of Ficus microcarpa is generally 3-4 meters between plants and 4-5 meters between rows; There are no flowers and plants in Branrick, with a spacing of 2 □ 5-3 meters and a row spacing of 4 meters. □
2. Soil, fertilizer and water management Soil management can be carried out with reference to general orchards. Manure, soil mixed fertilizer and compound fertilizer can all be used as base fertilizer, and chicken manure is the best. The application time is early spring and after autumn. As for the types of topdressing, diammonium phosphate is mainly used in the early growth stage, and ammonium bicarbonate and urea are not used; Potassium dihydrogen phosphate should be applied in the late growth stage. Relatively speaking, figs are drought-resistant and waterlogged-resistant. Pay attention to irrigation in spring and before overwintering, and do a good job in flood control and drainage during the growing period. □
3. It is suitable for shaping and pruning of fig tree cultivation. The stem is fixed in the first year of planting, and the height of the stem is 40-60 cm. In the second year, cut 30-40 cm branches, increase branching ability, control tree height, and keep 4-7 main branches. After that, every summer, the long branches over 50 cm should be cored to control vigorous growth, or sprayed with dwarfing agents. At the same time, sparse roots and tillers, too dense branches and twigs.
4. Protection of young trees in winter In the year of planting, young fig trees have poor cold resistance and serious drainage, so protective measures should be taken. The simple method is to cultivate the soil at the root of the trunk for 20-30 cm and tie the straw rope with branches.
