1. Growth habits
Oroxylum indicum prefers a warm and humid climate, is not cold-tolerant, and tolerates drought and poor soil, so it has no strict requirements for soil. When planting, it is best to choose a warm, sunny plot. To obtain high yields, fertile, loose, well-drained sandy loam is preferable. If the soil's fertilizer content is low, although it can grow normally, the speed is relatively slow, so before planting, base fertilizer can be applied according to the soil's fertilizer condition. The base fertilizer is mainly organic fertilizer. After applying the fertilizer, level and rake the soil, and wait for planting.
2. Propagation methods
It is mainly propagated by seeds. When the fruit matures, collect it and dry it in a ventilated place. After the outer skin of the fruit dries, remove the outer skin and take out the seeds for planting. Choose a plot with sufficient sunlight and loose, breathable soil as the seedling bed. Before sowing, disinfect and sterilize the soil to increase yield. It can be sown in rows or broadcast. Before sowing, soak in clean water for 24 hours, wait until fully absorbed, then remove and dry before sowing. After sowing, cover with soil about 1-2 cm. If the soil covering is too deep, the seeds may rot. After covering with soil, water to keep the soil moist. Before emergence, water frequently to keep the seedbed moist to facilitate emergence. Rice straw can also be used as cover, but it must be removed promptly after emergence.
3. Transplanting
After one year of sowing, transplanting can be carried out in winter or spring. When transplanting, pay attention to density, and dig holes 30 cm deep and more than 30 cm long and wide. Apply 5-6 kg of decomposed farmyard manure at the bottom of the hole, backfill some soil and mix evenly, place the plant upright in the hole, spread the root system out, and do not let it twist together, so as not to affect plant growth. When filling soil, generally lift the seedling slightly, then firm it. The covering soil should be higher than the hole. After planting, water once with settling water to help survival.
4. Field management
After the seedlings emerge, water frequently to keep the soil moist, and weed promptly so that there are no weeds in the field. After each weeding, fertilizer can be applied once, mainly as a topdressing of clear manure water, or in winter and spring, combined with weeding, use plant ash or other fertilizers. It is also possible in summer during the high-temperature rainy season in May-June to apply decomposed farmyard manure around the plants.
