Detailed Explanation of Key Techniques for Summer Management of Plum Trees
1 Summer pruning 1.1 Bud rubbing and shoot removal. Removing buds immediately after they sprout is called bud rubbing; when the sprouted buds develop into tender shoots, cutting or pinching them off is called shoot removal. 1.2 Pinching. Pinching can be done when new shoots grow to 10~15 cm. The number of pinchings depends on the tree's vigor and requirements

What are the key points of autumn management techniques for plum orchards?
Autumn is an important period for plum trees to restore tree vigor and accumulate nutrients in the tree body. Applying scientific management measures can increase the reserve of tree nutrients, promote further differentiation of flower buds, and lay a good foundation for high yield and high quality in the following year. Through many years of practice, whenever the management techniques of this period

Detailed Explanation of the "Three Early" Cultivation Techniques for Plums
"Three Early" cultivation techniques for plums: 1. Reasonable pruning to promote early flower bud formation: In the year the plum is planted, when the new shoots grow to about 30 cm, pinch off the growing tips to control growth, stimulate secondary shoots and form flower buds. For example, on Misi plum, Oishinaka, and Oishiwase, after pinching, 40% of the secondary shoots can form flower buds, while plum trees not pinched in summer generally do not form flower buds that year. During winter pruning in the first year, current-year branches are generally left unpruned and laid flat, while densely crowded branches, water sprouts and shade-casting branches are removed by thinning. In this way, a large number of clustered flower buds can form on the laid-flat branches of that year. During winter pruning in the third year, the branches that were laid flat are appropriately retracted to prevent the tree from weakening. In subsequent years' winter pruning, the same pruning sequence is used.

Plum Seed Sowing and Seedling Raising Methods and Key Points of Seedling Stage Management Techniques
Plum Seed Sowing and Seedling Raising and Seedling Stage Management Methods: 1. Nursery Site Selection The nursery site should be selected in a place with flat terrain and loose, fertile soil. Before winter, irrigate first and plow deep. In late March, prepare the land and lay plastic film. The plastic film is best laid in a north-south direction so that the seedlings can receive uniform light

Key Points of Early High-Yield Cultivation Techniques for Peach Trees
In the spring of 2002, a peach orchard of 0.67 hm2 was established in Yutian County, Tangshan City, with the cultivars Shijiwang Tao and Shijihong Tao. In 2003, the average yield per 667 m2 was 890 kg; in 2004 it reached 2400 kg; and in 2005, 2006, and 2007 the yield stabilized at 3500 kg. The specific management techniques are described below.

Detailed Explanation of Key Points of Winter Pruning Techniques for Peach Trees
Winter pruning of peach trees can be carried out from after leaf fall until bud break the following year. During winter pruning, it is important to grasp the following points: 1. Be sure to determine the pruning plan and methods based on the growth and fruiting habits of peach trees. 1. Peach trees are extremely heliophilous (sun-loving) species. Therefore, in pruning, full

Management Techniques After Jujube Trees Lose Their Leaves
1. Increasing Fertilizer and Water. Jujube trees consume a large amount of nutrients during a year of growth and fruiting, which need to be replenished in time. Fertilize after the jujube trees lose their leaves and before the soil freezes. If no fertilizer was applied before the end of the year, it should also be applied as a supplemental dressing before sprouting in early spring. Fertilizer can be applied by broadcasting or trenching. Broadcasting means spreading

Key points of pollution-free control techniques for citrus cultivation
When chemical pesticides are used to control citrus pests and diseases, costs are high and resistance is easily developed. Guiding fruit growers to use the following simple and economical methods gives good results in controlling certain citrus pests and diseases. The specific control methods are as follows. 1. Plant ash to control citrus leafminer: during the shoot-flushing period, start when the new shoot has grown to about 3 cm, and continue until the new shoot matures, sprinkling once every 5-7 days for 5-6 consecutive times, and during the interval, replenish promptly after rain. In the early morning when the dew has not dried, or after rain, or after watering, promptly sprinkle plant ash onto the upper and lower surfaces of the leaves of the new citrus shoots. Throughout the shoot period, the leaves should remain constantly coated with the ash powder until the shoot leaves mature. This method is suitable for greenhouse or open-air citrus nurseries, young citrus orchards, and potted ornamental citrus for controlling citrus leafminer.

Detailed Explanation of Key Points for Frost Protection Techniques in Citrus Cultivation
For fruit trees that have suffered relatively severe frost damage, adopt tree-preservation measures: First, mound soil to increase temperature. Mounding soil protects the root crown; the standard for mounding is that the root system is not exposed and the root crown is covered. Second, whitewash and wrap the branches and trunk. The trunk and main branches form the tree framework and are prone to frost damage, which leads to weakened tree vigor
