Taiwan green jujube adaptability, the soil requirements are not strict, but on the water source, sunlight, fertilizer requirements are higher, the planting of green jujube cultivation technology mainly has the garden selection, variety selection, reasonable dense planting, timely planting, fertilizer technology, water management, pruning, pruning, erection, disease and pest control, fruit thinning fruit protection, harvesting and so on.
Taiwan big green jujube planting cultivation management technology "a" early management
(a) selecting seeds
This is an important level of big green jujube seedling planting. At present, the big green jujube planting base planting Taiwan big green jujube new varieties to honey silk jujube, day honey jujube, snow honey jujube, gold honey jujube, GaoLang No. 1 mainly, are performing well. Purchase wholesale jujube seedlings must be to have "three certificates" complete nursery professional units, so as not to cause losses.
(2) site selection
1, soil: big green jujube seedlings on the soil adaptability, can in sandy soil, gravel soil, clay and loam and so on a variety of types of soil growth. pH value of 6.0-7.5 are available. Planted on loose sandy soil and sandy loam, the fruit quality is good. On deep, fertile loamy soil, big green jujube grows vigorously and produces stable yields.
2, terrain: big green jujube seedlings can be planted in mountains, hills, flat land.
(3) Planting
The planting time is most suitable from February to April, depending on the weather. Where there is water, it can be planted throughout the year.
1, the number of per mu: Taiwan big green jujube grows rapidly, canopy expansion fast, ordinary cultivation to 2 × 3 meters is appropriate, mu planted about 110 plants; dense cultivation: 2.5 × 2.5 meters, mu loaded about 110 plants; dense planting is conducive to the early high-yield, specific or look at their own land fertile length to measure the number of mu planting, mu planting is generally between 70-110 plants is appropriate.
2, planting method: planting planting hole diameter 45-80 cm wide and deep, to rotting compost 12-20 kg plus composite fertilizer 0.5 kg, calcium magnesium phosphate 0.5 kg, magnesium phosphate 0.2 kg, boron fertilizer 0.025 kg, a small amount of quicklime mixed with the marking of the map to fill in the solid, and then planting compression, seedling bases around the do 20 cm shallow basin, to facilitate the irrigation, the basic wrapping, when necessary Straw, in order to prevent the scorching sun. Good drainage to avoid flooding, set up a pillar to fix the seedlings, to avoid the wind blowing loose, affecting growth.
3. Pollination tree selection: some varieties need to be interplanted pollination tree is easy to results, some do not need. Need to pollinate the tree, the results of the tree and pollination tree than 1 to 1 the best, at least 10 to 1 is appropriate. Can choose 1-2 varieties of mixed load, mutual pollination tree, can improve yield. Taiwan big green jujube planting cultivation technology

4, overall pruning: Taiwan honey jujube side branch oblique, crown area is large, pruning diligently to maintain good tree type, can reduce the management of the operation of the many inconveniences, and the light ventilation is good, can reduce the occurrence of diseases and pests, reduce the amount of pesticide use, improve the quality of the jujube need to be renewed every year! Main trunk. Young trees to single trunk branching is the main. One year old jujube tree, from the grafting mouth 15-25 centimeters at the cut, induced growth of lateral branches, selected robust, good growth position, guided around 3-4 lateral branches for the main trunk, long to 1.5 meters before cutting small bud body. 1.5 meters high, let the lateral branches grow diagonally, cut off the unproductive branches and young branch tips. www.twdqz.com台湾大青枣种植基地栽培2 Year-old jujube tree, need to renew the trunk once a year, in February-March after picking the fruit, in the trunk of the ground at 20 centimeters sawing renewal or grafting, new tips grafting spikes sprouting new shoots, stay in a good fertility, the location of the new shoots of the appropriate 2-3 branches of the new trunk of the year, and the rest of the shoots cut off, so that the new trunk of the birth of a strong. After the trunk grows into, make both sides of the oblique branching, branch regeneration branchlets, branchlets leaf axils bearing flower spikes, August-October can blossom and fruit .
5, plowing and weeding: jujube garden do not need to start border planting, as long as the middle of the line ditch so that irrigation, drainage can be, do not need plowing. Big green jujube is shallow rooted fruit trees, herbicides easy to hurt the roots, the results of the period can not be suddenly dry and wet, grass cultivation is not only suitable for big green jujube growth, but also can reduce the loss of soil fertilizer, grass is too high can be cut, used to give jujube roots shade, jujube garden planting animal husbandry with Baxi grass, can be multi-purpose.
6, irrigation and drainage: big green jujube in the flowering period before a month and young fruit period should be kept dry, not irrigation. Other time orchard need often keep wet can. Suddenly rain suddenly dry or a dry and wet irrigation method, will lead to serious fruit drop and fruit cracking phenomenon.
7, flower thinning and fruits and vegetables: flowering and fruiting fruit trees in order to improve the quality of fruit, increase fruit development, need to carry out fruits and vegetables, the best in the fruit to reduce the flowering, to avoid the consumption of nutrients, to the tree plant leaf growth situation to determine the amount of fruits, 3 basic piece of leaf to stay 1 fruit, end of the fruits can not be stayed, in October, November bagging the end of the branch tip of the flower spikes or young fruits and too dense flower spikes removed. Taiwan big green jujube planting to remove the top of the flower spike and young fruits, at the same time will be small fruits, deformed fruits, disease and insect fruits are thinned out, reduce the consumption of nutrients, promote fruit expansion.
8, bagging: big green jujube skin young thin, and by wind injury and pests, bird damage, the implementation of bagging operations, in order to ensure that the big green jujube skin bright, good quality. Choose sunny weather, after spraying sterilization, insecticide immediately bagging, and at the same time, flower thinning, fruit and vegetable operations.
9, set up bracket: big green jujube branch tip slender and fragile, the results of too much paper often due to overload and break, need to set up pillars or around the frame fixed.
