In summer, fig trees should be watered once in the morning and once in the evening (don't water them at high temperature at noon). Once the water is not timely, there will be dead leaves and fruit; Excessive watering leads to overgrowth and fruit cracking. * * * Pot cultivation technology of fig * *1,propagation and cultivation of fig trees. The propagation of fig trees is mainly cutting. In late April, in combination with pruning, plump branches, about 20-30cm long, are selected, obliquely buried in flowerpot soil, covered with a thick layer of soil and compacted. The soil should be moist, and the callus can be transplanted into the prepared flowerpot after 20-30 days. Potted soil is mixed with 8 parts of sandy loam and 2 parts of fertilizer, and horseshoe is used as base fertilizer. After half a month, when new buds grow, they can move to sunny and windless places outside. If it is propagated by the roots of the mother tree, it is best to bring some roots to transplant. It is best to change a large flowerpot with an inner diameter of more than 35cm after the seedlings grow to 2 years, so that there will be enough water and fat feet. 2. When watering, fertilization and management enter the winter dormancy period, potted figs should be moved indoors and watered once every 1-2 weeks to keep the soil moist. When you are outdoors in spring, you should remove the roots attached to the basin wall, so that they can grow new roots, increase their ability to absorb nutrients, and prevent the roots from being damaged by the sun in summer. Fertilizer should be applied once after the bamboo shoots grow, which can be decomposed cake fertilizer or chicken manure. These two fertilizers are rich in nitrogen, phosphorus and potassium, which can make branches flourish and leaves grow early. Watering once a day in early spring and autumn can keep the soil moist. When the fruit is ripe in summer, water it once in the morning and once in the evening (don't water it at noon in hot weather). Once the water is not timely, there will be dead leaves and fruit; Excessive watering leads to overgrowth and fruit cracking. 3. The balcony is poorly ventilated. When it is hot and rainy in summer, fig branches are vulnerable to red spiders. Starscream likes to build a net cover between the fruit and the petiole for more than a year, especially in July and August. After the plant was killed, the leaves appeared yellow and white spots, the growth declined and the leaves fell off, which made the fruit lose its green luster and even dropped fruit. To control the red spider, we can spray 1000- 1500 times dimethoate diluent on the leaves. To prevent and control the overwintering female insect emergence peak and the first generation female insect incubation peak, 600-800 times diluted solution of 20% dicofol emulsifiable concentrate should be sprayed. When the number of potted plants at home is small and pests are found near the ripe fruit stage, in order to avoid pesticide residues, garlic slurry diluted by 10-20 times can be filtered and sprayed on the whole plant and pot soil, and it can be killed by repeating twice. 4. Pruning and shaping are the main ways of fig cultivation in the open field in northern China. These trees need no special management. Branches and leaves grow vigorously, naturally forming a large crown, but the fruit is late and the number is small. It is often when the autumn fruit is not mature that the weather gets colder and there is no harvest. Potted figs are well managed, smaller than open branches, and prone to premature and premature birth. The 23-year-old fruit branches can be truncated at the height of 60-70cm in July, and then 4- 15 full buds are left at the top as the main branch forming parts, and the rest buds can be removed. After the main branches germinate, select three or four main branches with suitable positions, leave 1-3 terminal buds on each main branch to form side branches, and the left branches are evenly distributed around the trunk to form a balanced crown of master-slave relationship. Potted fig branches grow short and dense, and cannot be pruned after 4 years. In order to occupy less indoor space in winter, branches and tree crowns can be stored in a fan shape.
