Peaches and plums can be planted at intervals.

Peach planting

The spacing between planting rows is 4m×5m or 3m×4m, and 500-840 plants are planted per hectare. The planting period can be from after leaf fall to before germination. Peach orchards should not be continuously cropped, otherwise the growth of saplings will be significantly weakened, leaves will turn green, new roots will turn brown and have many forks, and branches will ooze gum. This avoidance of continuous cropping is serious in sandy soil or upper soil with low fertility. The main reason is that the residual roots of the previous crop decompose in the soil to produce toxic substances such as benzaldehyde and cyanic acid, which inhibit and poison the root system. It is also related to the proliferation and accumulation of nematodes in the soil during continuous cropping.

Peach fertilization

The ratio of nitrogen, phosphorus and potassium requirements of peaches is about 1:0. 5:1. Young trees need to pay attention to controlling the application of nitrogen fertilizer, otherwise it will easily cause excessive growth. Apply nitrogen fertilizer after the fruiting period to enhance tree vigor. The potassium content in peach fruits is 3.2 times that of nitrogen. If more potassium fertilizer is applied, the fruit will be large and the yield will be high. Fruit-bearing trees are fertilized three times a year: base fertilizer is applied in combination with deep soil plowing from October to November, mainly organic fertilizer, accounting for 50% of the annual fertilizer application; fruit-strengthening fertilizer is applied from late April to May during the fruit hard-core period. Early-maturing varieties are mainly applied with potassium fertilizer, and the amount of nitrogen applied to mid-late-maturing varieties accounts for 15%-20% of the year, phosphorus accounts for 20%-30%, and potassium accounts for 40%; fruit-picking fertilizers are applied before and after fruit picking, and the application amount accounts for 10% of the total. 15%-20% of the year. In addition, peach orchards need to be frequently plowed and weeded, the soil kept loose and drained in time to prevent water accumulation and root rot.

Peach plastic surgery

It is usually done into a natural happy shape. Set the height of the trunk to about 60 cm, leave 3-4 main branches, the opening angle of the main branches is 50°-60°, leave 1-2 sub-main branches on each main branch, and leave as few twigs as possible on the main branches and sub-main branches. The pruning periods include winter pruning and summer pruning. Although the first-fruiting tree (3-4 years after planting) has produced fruit, it is still growing vigorously, with many leggy branches and dense branches. Summer pruning measures such as bud wiping, topping, and tip twisting are needed to suppress the strong and weak, and maintain the tree body. Balance: During the fruiting period, peach trees have become less vigorous due to years of fruiting. Leggy branches and secondary branches have been significantly reduced, and the proportion of medium- and short-fruited branches has increased. Short-cut branches must be the main ones, and overly dense branches and strong apex branches must be deleted. branches to improve the light conditions between shoots; weakened branches should be renewed in a timely manner.

Plums are highly adaptable to climate. As long as the soil is deep and has a certain degree of fertility, it can be grown in any soil quality. It has high requirements for air and soil moisture and is extremely intolerant of stagnant water. Poor drainage in the orchard often leads to root rot, poor growth or prone to various diseases. It is advisable to choose a place with loose soil, good soil aeration and drainage, deep soil layer and low groundwater level to build the garden.
