First, Wuxi Yangshan peach can be planted in tropical areas.

Second, climate.

Wuxi city belongs to the humid monsoon climate zone in the north subtropical zone, with four distinct seasons, abundant heat, abundant precipitation and the same season of rain and heat. Summer is controlled by the summer monsoon from the ocean, with southeast wind prevailing and hot and rainy weather; Winter is controlled by the prevailing winter wind in Chinese mainland, with more northerly winds; Spring and autumn is a period of alternating winter and summer monsoon, with changeable weather in spring and fresh air in autumn. Annual (30-year statistics 198 1 ~ 20 10) average temperature 16.2℃, precipitation1/21.7 mm, rainy days/kloc. The hottest month in a year is July and the coldest month is 1. Common meteorological disasters include typhoon, rainstorm, continuous rain, cold wave, hail and strong wind. It has the characteristics of both north and south agriculture and a wide variety of crops.

Yangshan peach is one of the famous specialties in Wuxi, with a cultivation history of nearly 70 years. Yangshan peach is produced in Yangshan Town, Wuxi City, Jiangsu Province, a famous peach town in China. It is famous at home and abroad for its beautiful appearance, bright color, delicious taste, delicate meat, tough and easy peeling skin, rich juice, rich flavor and instant taste. Yangshan Taozaotao varieties began to be listed at the end of May, and around June 15, a large number of lakeview peaches with the highest sweetness will also be listed. 20 13 1.5, the trademark "Yangshan" won the list of newly recognized well-known trademarks in China announced by the State Administration for Industry and Commerce.

Fourth, cultivation techniques.

1. Seedling selection: according to the soil, climate, management level and local market conditions, select excellent varieties with high yield and suitable production and marketing, and do a good job in matching early, middle and late maturity varieties.

2. Garden planting: select slightly acidic sandy soil or sandy loam with good drainage, deep soil layer and ph value of 5.5 ~ 6.5, and dig big holes for planting; Terraces should be built on low hills and slopes, with planting density of 40-50 plants per mu in flat land and 50-60 plants in mountainous areas.

3. Apply sufficient base fertilizer and timely topdressing: the base fertilizer advocates winter fertilizer and autumn fertilizer, mainly organic fertilizer, accounting for 60% ~ 70% of the annual fertilization, and generally apply 2000kg or150 kg of stable fertilizer per mu; Special fertilizer for fruit trees per mu; The frequency, time and dosage of topdressing vary according to varieties, tree ages, cultivation management methods, growth and development periods and external conditions. Generally, pre-bud fertilizer, strong fruit fertilizer and post-harvest fertilizer are the main fertilizers.

4, plastic pruning technology:

(1) Tree and tree structure: Tree is naturally happy with three main branches. Tree structure: the height of adult trees is about 2.5 ~ 3 meters, the trunk is 30 ~ 40 cm high, and there are three main branches, each of which occupies the direction of 120. Each main branch is equipped with 1 ~ 2 auxiliary branches, and the opening angle is about 75.

(2) Tree culture: the stem should be fixed at 50 ~ 60 cm in the year of planting, and there should be more than three robust buds in the plastic belt under the incision. In the first year of growth after planting, new shoots with strong growth and good orientation are selected as main branches for cultivation, and the remaining new shoots can be thinned or twisted as auxiliary branches. In the second year after planting, select strong lateral branches 50 ~ 60 cm away from the main branches with good opening angle, cultivate auxiliary main branches, and cultivate large and small fruiting branches on both main branches and auxiliary main branches.

(3) Pruning: Pruning during hibernation (winter). It can be carried out after defoliation and before germination, and pruning adopts the combination of short cutting and thinning, as well as measures such as long laying, shrinking branches and winding branches. Pruning of fruit branches: long fruit branches, about one-third of the branch length; The middle fruit branches are generally not short except for sparse branches and dense branches; Short fruit branches should be left 10 cm/branch. The amount of branches left depends on site conditions, management level, tree age, tree potential and yield requirements. Pruning in growth period mainly includes technical measures such as re-pruning, de-sprouting, thinning, twisting, pinching, pulling, cutting tips and moving branches after flowering.

5. Fruit management technology: peach has a high fruit setting rate, so it is necessary to thin the fruit and control the amount of fruit left. Fruit thinning should be carried out twice, from late April to early May and middle and late May respectively. Generally, short fruit branches leave 1 fruit, middle fruit branches leave 2 fruits, and long fruit branches leave 3 ~ 5 fruits. Spraying and bagging in time after fruit setting. The harvest time of fruit depends on the characteristics of varieties, and it is appropriate to harvest eight-ripe fruits.

6, pest control: to prevent diseases, we must first do a good job of clearing the garden in winter, combined with winter pruning to remove diseased branches and leaves in time; Before and after beginning of winter, the trunk was painted white; Spraying Pomei 5-degree sulfur mixture before germination in early spring to control brown rot, anthracnose, scab, leaf shrinkage and other diseases in the growing period. Pests that harm peach trees include aphids, pear moth, green leafhopper, peach moth, thorn moth, military pest, mulberry white scale and so on. , should be sprayed in time according to the situation.
