How to plant green plum trees?

1. Planting density: for the flat land or gentle slope with good soil conditions, the plant row spacing of 4m × 4m was adopted, 42 plants per mu were planted. For the sloping land, in order to increase the early yield, the planned close planting was carried out, and the plant row spacing of 3m × 4m was adopted, planting 55 plants per mu.

two。 Planting method: first, after determining the central position of the planting pit as the planting point, dig a hole with deep 30cm and wide 40cm. Secondly, after unwrapping the selected grafted seedlings, the seedlings were placed upright in the planting hole, so that the roots were evenly distributed in the holes, the soil was gently cultivated in the roots, and the seedlings were gently raised after mulching, so that the roots were extended and fully contacted with the soil, while filling the soil, the grafting interface was exposed 5-10cm, the tree disk was higher than the ground 20cm, and the roots were covered with plastic film. If there are dead seedlings within a month, they should be replenished in time.

3. Intertillage management: intertillage management mainly includes soil cultivation and root protection, intertillage and weeding. The root system of causal plum is shallow and the leaves fall early. Attention should be paid to turning the mature soil deeply and introducing the root into the soil to thicken the root soil layer, prevent sunburn and conserve water. Generally, the soil is fertilized in combination with deep ploughing and loosening in autumn, and weeding is carried out timely according to the local climate and the number of soil weeds, so as to keep the soil loose and grass-free in the tree plate.

4. Water management: irrigation according to the physiological water demand of plums combined with fertilization, while paying attention to drainage, making deep ditches and high beds in the garden according to the row, keeping good drainage and no stagnant water in the garden.

5. Fertilization management: base fertilizer is generally applied in autumn every year, and in August at the latest, in order to facilitate root absorption. Fertilization accounts for 60% of the total amount of fertilizer applied throughout the year, mainly farm manure, general plant application of 50kg, and combined application of phosphate fertilizer 1kg, nitrogen fertilizer 0.5kg, young trees can be reduced. The pre-flowering fertilizer was applied in the flower bud expansion stage, usually from November to December. The young trees were treated with nitrogen fertilizer 0.25kg, potassium sulfate 0.25kg, rotten cake fertilizer 1kg, and fruit trees were applied nitrogen fertilizer 1kg, potassium fertilizer 1kg, mature cake fertilizer 1.5kg. At the same time, the proportion of fertilization was adjusted according to the fruit amount of the current year.

6. Moderate pruning: winter pruning is generally carried out from defoliation to flower bud germination, including short pruning, thinning, long release, shrinking, opening angle and so on. Plum trees are mainly medium and short fruit branches, cut as little as possible in winter, cut long and put as much as possible, in order to form early fruit of medium and short fruit branches; wipe buds and remove sprouting, coring and twisting, brace and twist branches, bend branches in spring and summer, pay attention to timely and moderate pruning.

The main value of green plum tree

1. Green plum has the functions of detoxification and beauty, freckle and acne, slimming and slimming, reducing blood pressure, clearing liver and eyesight, relieving alcohol and oil, and so on.
