Fig cultivation technology

1, garden and planting. The fig tree is not strict with the soil, and the soil with deep, moist, fertile clay and sandy soil is suitable for slightly acidic to slightly alkaline, and it is extremely drought tolerant. Potted plants are often withered if watering is not done in time or if the basin is too small. The garden terraces (ladder, terraced field) should be more than 3m. There are bamboo scallops with ridges, internal grooves, and widths of 30cm each. The depth and width of the planting holes are each 1m, and 750 plants are planted per hectare (Daejeon The number of plants is appropriate.) Before planting, the base fertilizer should be applied. Each hole should be applied with 1kg of lime, 1.5kg of cake fertilizer, 50kg of burning earth or 1kg of pond mud, and 1kg of phosphate fertilizer. One layer of fertilizer is mixed with layered soil, and the expansion of the hole is completed within three years after the planting. 2, fertilization. Every year, the basal fertilizer should be applied 1 time before falling leaves in early autumn to early spring. Top dressing is divided into spring, summer and autumn. The adult orchards use 90-120 kg of pure nitrogen per hectare, 120-150 kg of pure phosphorus, and 60 kg of pure potassium. The nitrogen fertilizer should not be too much, so as to avoid freezing the shoots and twigs. Saplings are irrigated 2 or 3 times a year, and adult trees 6 to 7 times. Before winter, irrigation should be performed in winter, and garden fertilization or potting should also be applied 3 times. The first time is the germinating fertilizer in early spring; the second time is the maintenance of fruit fertilizer; the third is the wintering fertilizer. When the potted plants were changed once a year in the first few years, they were changed into barrels a few years later. 3, breeding. Use cutting method. Branches are very easy to root, naphthalene acetate, rooting powder, 2,4-d can promote rooting. Hardwood cuttings are usually carried out in early spring, and young shoots with roots sprouting from the main stem base can also be cut in the growing season. The survival rate is high, but the lateral branches cannot be cut during growth. High-pressure reproduction should be carried out during the growth period from April to June. 1 cm girdling at the base of 1 year, 1/3 of epidermis, 1/3 of dry skin, 1 day of dryness, loosening with loose topsoil, then wrapping with plastic cloth, forming a new root after 1 month, until it reaches a new root. The entire bag was removed and transplanted. 4, pruning. High-dry, non-layered or multi-branch natural open-heart shapes should be used. The trunk without stratified mainstays is left short by 30-50 cm, and 4 to 5 main branches in different directions are retained, followed by short cuts at 40-60 cm in the main branches, and 2 to 3 secondary branches are formed on each main branch. Due to weak branching force, light-scissor-based branches should be used to remove drooping branches, stem branches, unused long branches and closed branches, and the remaining branches are allowed to grow. For species with large growth, strong uprightness, and weak branching power, adult trees should be cut short and the side branches should be promoted. To advance the results, promote the formation of tree crowns, light and short cuts should be taken in the spring, and take heart in the summer to stimulate lateral branch growth.
