Field cultivation and management techniques of sycamore

1. Choose sunny, warm and moist, well-drained, deep and fertile soil for land preparation.

two。 Seed propagation, cuttage and root division are often used in propagation.

After the seeds are ripe, they are harvested for autumn and spring sowing. Sowing as soon as it is picked, seeds can also be stored until spring sowing in the following year because of irregular seed germination rate. Soak seeds with wet sand stratification or warm water to accelerate germination before sowing. Make a seedbed before sowing, open a shallow trench according to the row spacing of 30cm, and then sow in the ditch or on demand, with a sowing rate of 75-120kg per hectare. After sowing 3-4cm, cover and moisturize with straw, wait for the seedlings to be unearthed, and gradually remove the mulch.

3. The seedlings of field management can be fixed according to 20-25cm when combined with inter-seedlings for intermediate tillage and weeding. According to the growth of seedling stage, one-year-old seedlings can reach more than 80cm by proper topdressing.

Sycamore likes to grow on sunny, open and sheltered hillsides, and it is suitable for slightly acidic or neutral soil with fertile soil layer and good drainage. Therefore, it is important to select suitable forest land before planting. When planting, the land should be carefully arranged, and each tree hole should be dug into 40-50cm in diameter and 30-35cm in depth. 5-6kg mature barnyard manure should be applied in the hole, and the dung and soil should be mixed evenly, and 1 seedling should be planted in each hole. The canopy of sycamore is expanded, and the root width is huge, so it should not be too dense when planting. It can plant about 900 trees per hectare. Watering in time after planting, and pay attention to management. Gardens and afforestation can be planted with other tree species. In order to make effective use of the woodland, the woodland planted alone can be interplanted with other crops in the early stage, and the trees will become pure forest in the later stage.
