Shatin pomelo alias wendan, for the rutaceae citrus plants, because of its rich nutritional value, with stomach, lung, and other effects, and by the consumers' favorite.

So, where is the origin of Shatian pomelo? How to plant it? Now the origin of pomelo and origin environment, as well as planting techniques are introduced as follows:

One, the origin of pomelo and origin environment

1, the origin of pomelo

Shada pomelo for the Guangxi Zhuang Autonomous Region Rongxian specialty, because of the first planting of Guangxi Rongxian Shatian Village, so called Shada pomelo, as early as the 30s on the export of Hong Kong, the South Seas, Europe and the Americas and other places.

Now expanding to Guangxi Xunjiang, Longjiang, Guijiang, Li River and Hongshui River Basin and other places, Guangdong, Hunan, Sichuan, Zhejiang, Jiangxi has also introduced, in 2013, Guangxi has become China's large concentration of pomelo producing areas, the autonomous region of pomelo planting area of hundreds of thousands of acres.

2, Shatian pomelo origin environment

Shatian pomelo needs fertilizer and water, so the development of fertilizer and water is the development of Shatian pomelo must be the first to consider the important conditions, you must choose the soil is deep, loose, fertile, water sufficient place to build a garden, the mountainous terrain should be selected in the slope of 20 degrees or less back to the south of the north of the gentle slopes of the hill should be a water source of forests, wherever you can grow oranges can be grown in the place of planting Shatian pomelo.

Two, Shatian pomelo planting technology

1, garden construction

Shatian pomelo must choose the soil layer is deep, loose, fertile, water sufficient place to build a garden, the mountain should be selected in the slope of 20 degrees or less, the back of the north to the south of the gently sloping, the top of the mountain should be water forest.

Reasonable arrangement of plots, roads, cesspools, pools and drainage systems, do a good job of land preparation, open planting holes, base fertilizer, soil change and other pre-planting preparations, planting holes specifications 111 meters, back to the soil per hole to add organic fertilizer, green manure, topsoil, a small amount of lime.

After planting holes piled up higher than the ground 30 centimeters, 100 centimeters in diameter of the garden-shaped planting mound, this work in the planting of 1-2 months before completion.

2, seedling cultivation

Shatin pomelo seedling cultivation of grafting, barge and cuttings of several kinds of methods, but the production practice to grafting seedlings superior to the barge and cuttings of seedlings, so the production practice of grafting method of reproduction of pomelo seedlings, barge and cuttings of the method gradually phased out.

In order to accelerate the propagation of seedlings to adapt to the development of pomelo production needs, as far as possible, the use of smaller rootstock seedlings grafting, grafting method has a small bud cut method, branch cut method and the "T" bud method, small bud cut method is more suitable for small rootstocks, can be grafted earlier, earlier out of the nursery.

3, planting technology

Shatin pomelo planting time is usually in the spring after the mature line spring planting (April-May) and autumn after the mature line fall planting, planting before the size of the seedling grading, planting seedlings of the same level together, cut off the long roots and dense branch tips, retaining the 3 to 4 main branches, and will be dipped in the mud before planting.

Plant with the grafted interface exposed to the soil, tap the soil between the roots fine, and allow the root mass to spread in all directions.

Mulch the soil and then lift the seedling slightly upward, tread firmly and cover with fine soil.

After planting, we should pour enough water to set the root, and then drench it once a day for the next 7 days to ensure survival, and insert windbreak poles and cover grass.

4, young tree management

Shatin pomelo young trees planted 20-30 days depending on the growth of seedlings in a timely manner fertilizer, but only after the application of thinly rotted organic fertilizer, in order to prevent injury to the new roots, and then monthly fertilizer 1 ~ 2 times, the concentration can be gradually increased.

After the planting has been completed, we should cut the top of the young tree from 50 cm above the ground to promote the growth of new shoots, and then leave 3~5 new shoots in different directions and evenly distributed as the main branch, and then cultivate 3 secondary branches on each main branch, cultivate lateral branches on the secondary branches, each branch is 15~23 cm long, and the angle is not enough can be pulled to shape the line.

5, tree management

Shatin pomelo fruit trees have four major fertilization period, namely, after the fruit fertilizer, pre-flowering fertilizer, stabilization of fruit fertilizer and promote the tip of the fruit fertilizer.

In addition, it should also be based on the plant's fruiting volume and tree strength to determine the need for supplemental fertilizer.

(1) fruiting fertilizer: fruiting fertilizer which is the focus of the fertilizer, about 50% of the annual nitrogen, organic fertilizer-based, long-lasting and, organic and inorganic combination.

Generally 40-50 kilograms of manure per plant with cow and pig pen, 50 kilograms of manure, 7 kilograms of rotted bran fertilizer, 2 kilograms of compound fertilizer, phosphate fertilizer and bone meal 1.5 kilograms each, 50 kilograms of fire soil ash, a few days after harvesting the fruits of the open trench between the plants layered buried.

For the results of more, the tree is weak, but also in the fruit about 1 week before the picking of an additional fertilizer, generally 40 kg of manure per plant, compound fertilizer 1 kg.

(2) pre-flowering fertilizer: pre-flowering fertilizer accounted for about 15% of the annual amount of nitrogen, generally in late January at the beginning of the spring sprouting Shi, the purpose is to promote the flower, promote the tip, so that the tip of the tip more, the tip of the strong, the flower is sound, which is not only conducive to improve the year's fruiting rate and yield, but also for the next year to lay a good foundation for the yield.

The main nitrogen fertilizer, with the application of phosphorus, potassium fertilizer, each available manure composted bran 50 kg (containing 2.5 kg of soybean bran, 1 kg of calcium superphosphate first composted) plus composite fertilizer and urea 0.5 kg each hole.

(3) stabilization of fruit fertilizer: stabilization of fruit fertilizer with nitrogen accounted for about 15% of the year, the purpose is to promote fruit expansion and stabilization of the fruit, generally in early April under the application to supplement the blossoming and fruiting consumption of nutrients to reduce fruit drop.

But it depends on the tree fertilization, on the first production, results less and strong tree, as long as to keep the leaves green, fruit green, may not be applied, or the use of weak trees to supplement the fertilizer, or combined with the de-worming of extra-root fertilization with compound fertilizer and potash per plant each 1 kg, 0.5 kg of urea, manure 25 kg of water.

In addition, it is also necessary to use imported urea 0.1 kilograms, potassium dihydrogen phosphate 0.1 kilograms with 50 kilograms of water for foliar spraying.

(4) strong fruit fertilizer: strong fruit fertilizer with nitrogen amount of about 20% of the year, the purpose is to meet the rapid increase in fruit and autumn spitting nutrients needed to ensure that the year's yield, especially the size and quality of the fruit.

This period of fertilization in July-August early in 2 times under the application of each plant with 2.5 kg of rotted bran fertilizer, composite fertilizer and potash fertilizer 1 kg, phosphate fertilizer and urea 0.5 kg each plus 100 kg of manure, and then after September, 1 kg of calcium superphosphate plus 50 kg of water for foliar fruit spray, to promote early maturation of the fruit, improve fruit quality.

6, harvest: generally after the autumnal equinox, Shatian pomelo began to turn into a mature stage, the skin from lime green gradually turned yellow, flesh juicy, taste from bitter to sweet.

By the time of frost to winter solstice, Shatian pomelo is basically ripe.

Production to the peel with yellow-green to orange-yellow, the flesh becomes soft, the flavor is strong and sweet, the aroma began to pick, the time is about the second half of October to the middle and end of November.
