Fertilization management Taoyuan fertilization should be based on the combination of land fertility, age, growth potential and yield. The fertile land is dominated by organic fertilizer in the 3 to 4 years of the young tree period. Mature trees produce a high amount of fruit, and the tree vigor is weaker than applying more organic fertilizers, and nitrogen, phosphorus and potassium fertilizers should be added. The time for fertilization can be carried out in the middle or late September of each year. The method is: in the peach tree circle digging a ring ditch, a small crown ditch near the tree away from the point of expansion a year, as little as possible to hurt the roots, ditch depth 25 to 30 cm, width 30 cm. When fertilizing, apply phosphate fertilizer to the bottom of the trench first, apply organic fertilizer, mix the soil and mix and fill in the trench. Immediately after the fertilization, apply the phosphate fertilizer. Four-way open fertilization can also be used. Topdressing N fertilization can be carried out in the growing season. Spraying Zhuangguo Tiling +0.3%~0.5% urea plus 0.3% KH2PO4 solution before spraying, young fruit, and fruit enlargement generally applies urea 0.1~. 0.2 kg.
The control of flowering peach trees is the easiest to draw, and it also tends to flow glue, affecting the reproductive growth of peach trees. The traditional girdling technique has serious damage to tree vigor and even causes dead trees. In order to accumulate nutrients for peach trees, supply flower buds and fruits, and use intelligent control to promote flower buds in the flower bud differentiation period of peach trees, it can replace paclobutrazol and other hormones to kill pesticides, replace fruit tree artificial girdling (opening), inhibit shoot growth, bidirectional Adjusting the size of the year (increased flowering in small years and reduced flowering in big year), the amount of flowering is balanced, and at the same time, returning large amounts of nutrients to fruit enlargement increases the quality of the pulp.
After irrigating the grasses and irrigating them, or after heavy rain, they must be cultivated in time to prevent soil compaction and poor ventilation and stop weed growth. The cultivator depth is generally 5 to 10 cm. When it is time to protect the trunk, do not cause man-made injuries. Use 10% glyphosate 500 times to kill weeds in the free space. It is sprayed twice a year during the growth period, and the best results are obtained from mid-June to mid-July. Be careful when spraying, do not spray liquid on the peach leaf surface.
The work of deep-turning the tree tray is a major agronomic measure managed by Taoyuan, which is conducive to the regularization of land conservation, the improvement of the micro-ring structure of the land, the preservation of land permeability, the adequacy of light, heat, water and oxygen, and the creation of beneficial peach trees. The environment reduces physical diseases. This work is carried out twice a year; in the early spring, Taoyuan pruning was carried out for the first time, in conjunction with the cleanup of the garden. Conditioning tree trenches is completed once. Don't turn the soil too deeply this time. Try not to hurt the roots. In the second autumn of the second autumn, combined with the basal fertilization in the fall, the fertilization, irrigation, and watering are immediately turned to the ground and deeper than in the spring. Injury of small roots helps stimulate new roots.
Plastic pruning peach tree characteristics are hi light, large growth, strong branching, large amount of mother branches. It is necessary to strictly control leggy branches, reduce the number of branches, and cultivate the result branches. During the growth period of peach trees, it is necessary to twist shoots or pick hearts on standing branches or branches to suppress the apical dominance and promote the formation of flower buds; thinning off dense branches and useless branches to improve ventilation and light transmission conditions. Winter shears need to remove strong back branch, disease and insect branches, overlapping branches, and competition branches, lightly cut the main branches to extend the head, and long-range some moderate branches to promote early fruiting. Trimming wounds should be promptly smeared with anti-corrosion film to protect the growth of wound healing tissue and prevent infection from the wound.
Clean orchard 1. When clear gardens are littered with litter, diseased and fallen fruit, and fruit with falling fruit in the orchard. 2. In winter and early spring, use general tree maintenance + lime sulfur to spray once in Taoyuan to eliminate overwintering pests and diseases. 3. Prevention and control of peach tree flowing water: remove peach gum, smear tree general to suppress the generation of gum pollution, cure peach tree gum disease; apply peach trees in the water of the peach water generals, heal the transmission catheter laceration, prevention and treatment Peach trees flow.
