Plum tree high-yielding cultivation technique

Colonization

Dig a hole with a length, width and height of 80 cm × 60 cm × 60 cm, and place the topsoil and the core soil separately. The topsoil and the fruit tree special compound fertilizer are 1 to 2 kg, the soil mixed fertilizer is 25 to 50 kg, and the decomposed farm manure or straw is mixed. Backfilling, and finally filling the core soil, making the mound 20 to 30 cm above the ground, showing a bun shape. Seedlings are planted during the dormant period. Seedlings with strong, complete roots, full buds, and no pests and diseases are used. The row spacing is 5 m × 3 m. Keep the seedlings on the ground, and then irrigate enough rooting water.

Plastic trim

After planting, it is set to dry, with a height of 40-60 cm. In the spring of the second year after planting, 3 to 4 branches with good growth, no pests and diseases and distributed to the surroundings are selected as the main branches from the newly germinated branches at the short cut. If the opening direction and angle of the branches do not meet the requirements of the tree shape, pull , Pressure, hanging and other methods to adjust; when the main branch selected to grow to about 50 cm, topping or short cut to promote the formation of side branches. In the third year of pruning, the main branches are shortened to extend the branches. The branches of about 5 cm on the main branches are kept as much as possible, which is conducive to the formation of bouquet-shaped fruit branches and short fruit branches. The medium and long fruit branches are appropriately pruned according to the situation. It should be noted that the pruning shears should be disinfected with 75% alcohol, and disinfected once for every 1-2 plants.

Soil, fertilizer and water management

Soil management. It is usually carried out from August to September. The deep turning methods include deep turning by rotary tiller and artificial deep turning. It is worth noting that when deep turning, try not to damage the root system. Deep turning can be carried out every other year, depending on the tree vigor.

base fertilizer. The young tree period is based on the principle of diligent application and thin application. Every year from sprouting to dormancy, mid-tillage and weeding are applied every month and farm fertilizer is applied, mixed with appropriate fertilizer. Beginning in the third year after planting, the base fertilizer is applied in September every year. The base fertilizer is mainly rotten farm manure. The amount of fertilizer depends on the tree vigor and yield. Generally, 30 to 50 kg is applied to each plant.

top dressing. Including early spring fertilizer, fruit stabilizing fertilizer, strong fruit fertilizer, fertilization method is the same as base fertilizer. Early spring fertilizers are generally carried out from late February to early March, stable fruit fertilizers are applied in early and mid April, and strong fruit fertilizers are applied in mid and late May.

Irrigation. Irrigate immediately after each fertilization. During the flowering period, fruit setting period and fruit expansion period, drought is encountered, and water should be irrigated immediately to ensure the supply of water.
