The invention discloses a
ligusticum wallichii cultivation method capable of reducing
plant pest and
disease damage and increasing
survival rate and yield. The method comprises the following steps: sequentially performing rice
seedling planting and rice harvesting, regular
soil preparation, poria seed planting, field management and
ligusticum wallichii harvesting within a planting period; specifically, in the regular
soil preparation, performing immersed soaking treatment on farmland with rice harvested, soaking and draining accumulated water out of the field, ploughing, then finely raking, flattening surface soil, ditching and excavating shallow trenches; in the poria seed planting step, performing cuttage on poria seeds at the bottom of the shallow trenches, and immediately covering with straws along the shallow trenches after cuttage; and in the field management step, supplementing seedlings, weeding, draining water, applying
fertilizer and performing pest and
disease prevention. According to the
ligusticum wallichii cultivation method, the block stem rotten sickness and grub damage of the ligusticum wallichii can be effectively reduced, the physiological
seedling death and withering are effectively prevented, the purpose of returning straws to the field can be achieved, the root development of the ligusticum wallichii can be promoted, the field weeds can be reduced, and the yield of the ligusticum wallichi can be effectively increased.
