Detailed Explanation of Fig Field Management Techniques
The fig is a type of fruit with strong vitality that can grow normally no matter where it is planted. Many people think it does not flower, but in fact it does bloom, only its flowering period is extremely short. So how should figs be managed? Let's take a look at the detailed introduction.
1. Cultivation and Weeding
Young trees should undergo cultivation and weeding once each in spring, summer, and winter. Winter cultivation should be combined with earthing up to prevent root frost damage. Adult trees should be cultivated during the dormant period after transplanting. In summer, grass should be spread as mulch to prevent weeds from running rampant and to prevent drought and preserve soil moisture. If weeds still grow, they can be cut and used to cover the root zone. In winter, appropriate intercropping can be carried out. In cold winter regions, attention should be paid to cold protection.
2. Fertilization
A mature orchard consumes 8-10 kg of nitrogen, 5-8 kg of phosphorus, and 8-10 kg of potassium per mu. There is no restriction on the types of fertilizer applied, but compost, farmyard manure, and plant ash are the main types. Base fertilizer should be applied during the dormant period of the fig, of which nitrogen fertilizer should account for two-thirds, potassium for half, and phosphorus fertilizer can be applied entirely; the remaining fertilizer can be applied in June-July. The shoot growth period and fruit harvest period of figs are both very long, so the supply of nitrogen and potassium fertilizer should be extended accordingly and must not be interrupted.
3. Drainage and Irrigation
When planted in heavy clay soil, the plant's root system is distributed in the surface soil layer. If it encounters hot weather and the ground is dry, it is prone to drought damage, so it should be watered promptly to replenish soil moisture and promote root growth. In plots without intercropping, grass should be spread in summer to keep warm and preserve moisture, which can both partially protect surface fibrous roots and increase soil organic matter content and fertility. When planting in low-lying areas, or in cases of improper watering or water accumulation after rain, drainage should be carried out promptly to avoid root rot.
4. Pruning
In order to control plant shape and improve the fruit-setting rate, appropriate pruning should be carried out each year when the plant is dormant, specifically pruning the main branches and secondary branches. To shape the tree, the three main branches of young trees should be left about 60 cm for heading back, leaving one cut bud at the tip to make it extend in the same direction. When the extension branch grows to a certain extent, it should also be headed back, and the length retained should not exceed that of the main branch, to establish clear branch hierarchy.
