杨梅栽培技术(Red bayberry cultivation techniques)Yang Meimiao belongs to the eye of Bayberry seedlings of Myrica rubra seedlings of evergreen fruit trees, with drought and barren resistance, strong growth, high yield and good characteristics of hi warm and humid, mainly distributed in the south of the Yangtze River Basin, north of Hainan Island, which is North Latitude 20 degrees -31 degrees・ Shiping County began in 1985 91 years of successful introduction of Bayberry seedlings, fruit, fruit, bright color, sweet and sour moderate, by consumers, after more than ten years of development, has begun to take shape・ Practice has proved that it has high eco nomic, ecological and social ben efits ・ Now Yang Meimiao has become the shiping advantageous agricultural products, however Yang Meimiao Shiping because of cultivated time is not long, many abnormal phenomena still exist during cultivation, now Yang Meimiao cultivation and management techniques were introduced as follows:Selection of varietiesWhen the selection of varieties should be early, middle and late maturing varieties collocation planting early maturing varieties can be selected 4 months late, Ding Aomei Shuimei maturity; medium maturing varieties to choose mature chestnut beginning in late April; late maturing varieties can choose in mid May start, mature carbon Mei Dong kui.Two, garden choice (1) altitude conditionsAccording to the shiping growing experienee, bayberry seedlings should be planted in the mountain slope at the altitude of 1300-1800 meters.(two) temperature condition;The optimum annual average temperature of Yang Meimiao growth is 15-21 degrees centigrade, the absolute minimum temperature is -9 degrees centigrade, and the maximum monthly average temperature is not more than 28 degrees centigrade・(three) rainfall and humidity;Yang Meimiao growth requires annual rainfall of about 1000 millimeters, with an average annual relative humidity of more than 70%.(four) soil condition;Yang Meimiao is suitable to grow in soft, good drainage, rich in gravel sandy red soil and yellow so订.The soil pH value between 4. 5~5・ 5, the growth of the wolf fern, azalea, pine, fir, bamboo, oak and other plants・ By planting practice, planting soil stone Yang Gang on bayberry seedlings can early fruiting early mature, sweet fruit・(five) slope direction and wind;Myrica rubra seedlings should be planted in mountainous slopes with convenient transportation and water resources・ The slopes are not strict enough to be planted on either side of the slope・Windy areas are not suitable for planting because the wind is too strong to affect pollination, fertilization and yield, and the trees are susceptible to wind damage・Three, seedling planting(I) preparation before planting;2 months before planting, digging planting hole, hole size 1 m x 1 x 0.8 meters, point after the excavation of sun Tong 1 weeks, every point of manure or fertilizer mixed garbage 30 50 kg or 5 ~ 6 kilograms of rotten cake plus 1 kg superphosphate as basal, soil to be kind・(two) planting time;The winter planting bare root in late December to early January, planting should be selected without cloudy. Bag seedlings as long as there is water guarantee, can be planted throughout the year ・(three) planting density;Depending on climate, soil fertility, soil thickness, and varietal characteristics・ Plant row spacing can be selected 4 meters x 4 meters, 4 meters x 5 meters, 3 meters x 5 meters, 33~40 per mu, East Kui should dilute, other varieties may be appropriate dense・ (four) planting techniques:Prune too long dnd split roots, leave a short cut of 25 30 cm and remove some of the leaves at the center of the nursery. All leaves should be removed in dry years・ When the root should stretch, do not touch the fertilizer, covering fine soil, compaction, in scion high 10 15 cm above the earth, enoughwater, and mulching in the tree set 1 meters,After the new plant seedlings should pay attention to watering・(five) allocation of male plants: the new area without wild Yang Meimiao should match 1 to 2% male plants to increase the pollination rate and seed setting rate of Yang Meimiao, and the location of male plants should be determined according to the terrain and the wind direction.Four, after planting management(1) soil management;1 young treesThe tree diameter of 1 meters to 1. 5 meters a year to clear brush and weeds, shallow scarification 2 〜3 times, and pay attention to watering, and pay attention to drainage・2, adult treeA flat garden with ^clean tillage method", combined with the application of fertilizer in autumn September soil improvement, remove weeds before seeding under canopy. The slope should be used ''natural grass'": the removal of miscellaneous shrubs and perennial herbaceous plants in winter when turning over the soil, let it grow an annual herb, only to cut grass under the canopy before harvest to harvest・3, expanding the cave earthThe secon。
