Abstract

Spirolobium cambodianum Baill. is used as a medicine to treat swollen limbs and is on the list of animal and plant species in Vietnam that are rare, decreasing in number or at risk. extinction. The goal of this research is to build a Spirolobium cambodianum Baill. seed production process for conservation and development. Research results show that the most suitable planting distance of 40 × 50 cm gives a yield of 128.37 kg/ha. With the amount of fertilizer 6 tons of microbial organic fertilizer + 400 kg N + 500 kg P₂O₅ + 300 kg K₂O/ha/year gives the highest yield of 158.5 kg/ha, germination rate of 66.8%. Through monitoring and evaluating the situation of pests and diseases in the fields, we see that the main pests appear such as gray caterpillars, small leaf rollers, gall nematodes and some types of aphids and mealybugs at a common level. varies from very little to little. Pests only appear during the growing season and do not have much effect on plant growth and productivity.
