Detailed explanation of plum seedling cultivation techniques, teaching you scientific planting step by step

I. Planting density

When planting, about 40 trees can be planted per mu, with a plant spacing of about 2 m and a row spacing of about 3 m. When raising seedlings, they can be sown broadcast at will, but once the seedlings emerge evenly, thinning must be done immediately, removing diseased seedlings, weak seedlings, and weeds, and then when they grow to about 3 cm, they should be transplanted once, and when they grow to 70 to 80 cm, they can begin to be transplanted while maintaining the above-mentioned plant and row spacing.

II. Planting time

Generally, in the south, planting is done in March in spring, or in the warm autumn period in October. These two times are relatively warm but not hot, and the rainfall is not especially heavy, which is favorable for root growth and tree survival; with less transpiration, less watering is needed, reducing the burden. In the north, autumn enters the cold period quickly, and the period is long, so spring planting is best, but spring planting must also be carried out after the soil thaws, otherwise the plants are likely to freeze to death.

III. Planting method

First, dig the planting pit. Although the seedling is less than one meter tall, it still needs to carry a 30 to 40 cm soil ball when transplanted. Also, for later growth, the pit must be dug about 80 cm deep and about 70 cm wide. When digging the soil, the topsoil, middle-layer soil, and subsoil should be placed separately. When planting, first mix the subsoil with base fertilizer and fallen leaves and backfill it, then cover the fertilizer soil with the middle-layer soil, place the sapling in, then cover with topsoil, gently lift the seedling, and then water with rooting water. Be sure to plant the seedling upright and straight, and let the roots spread naturally and hang down, rather than being tangled together randomly. Be sure to plant it in the exact center of the pit, leaving the same growing space on both sides so it does not grow lopsided. If it is a purchased seedling, be sure to replenish water in time, and after it recovers and stands upright, trim some roots before planting.
