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

How to cultivate double-cropping peaches? A full share of planting experience
With the progress of breeding technology, extremely early-maturing peaches (such as Siyuehong peach and Wuyuecui peach) and extremely late-maturing peaches (such as Xuetao, Shengtao and Dongtao) have appeared one after another, creating favorable conditions for extending the market supply period of peaches and improving the economic benefits of peach growers. However, in actual

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

Spring Pruning Methods and Technical Key Points for Densely Planted Jujube Trees
The small canopy open-center layered form has a trunk height of 80-90 cm. Suppress the secondary branches on the trunk and promote the development of 3-4 jujube heads (main shoots), so that the topmost jujube head extends upward to become the trunk extension branch, and the 2-3 jujube heads below are trained as main branches. In the second year, cut back the trunk branch leaving about 60 cm, and remove the

Methods for Preventing and Controlling Pests and Diseases of Winter Jujube Trees in Autumn and Winter, and Key Technical Points
After the beginning of autumn, winter jujube trees gradually enter the dormant period, and their tolerance to chemicals is relatively high. As temperatures drop, pests and diseases enter bark cracks, scars, branch forks, fallen leaves, fallen fruit, mummified fruit or the soil, where they lurk to overwinter. Therefore, it is necessary to seize the favorable opportunity for pest and disease control in autumn and winter,

Pollution-free control techniques for diseases, pests, and weeds in jujube trees
Fully implement the plant protection policy of giving priority to prevention and comprehensive control, base efforts on improving the orchard ecological environment and strengthening cultivation management, give priority to agricultural and ecological regulation measures, pay attention to protecting and utilizing natural enemies, and give full play to the natural control role of natural enemies. Select high-efficiency

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

Detailed Explanation of Key Cultivation Techniques for Newly Established Citrus Orchards
1. Orchard establishment should be of high quality and started early. The key points are digging the trenches well and applying sufficient basal fertilizer, passing the first hurdle of orchard establishment well. Dig continuous trenches 1 m wide and 0.6 m deep along the contour lines, fill each mu with 2500--30000 kg of green manure, and apply an appropriate amount of nitrogen and phosphorus fertilizer; next: for low-lying land and paddy fields, drainage ditches should be dug well, with the main drainage ditch more than 0.80 m deep, to reduce field humidity and lessen pest and disease damage. Orchard establishment should begin promptly after the autumn harvest to ensure enough time for the green manure and soil to decompose fully; field-grown seedlings are best planted before late October (mid-March in spring), while container seedlings should be planted earlier, before October (after March in spring); planting time should be early rather than late.
