The Latest Planting Methods and Key Technical Points for Orah Mandarins
Orah mandarin is a hybrid late-maturing citrus variety. The Orah mandarin has very strong growth vigor; in the early stage, the canopy takes on a natural round-headed shape, and after fruiting it gradually opens up. Its fruit is oblate in shape, with relatively smooth, orange-colored peel, and is rich in vitamins. However, Orah mandarins are very difficult to grow, and a single misstep can cause a large number of trees to fail to bear fruit. So how should Orah mandarins be planted? Let's take a look below!
1. Site selection and fertilization
If you want to achieve early fruiting and a high, bountiful yield, the choice of orchard is extremely important. When selecting a planting site, you should choose a place with fertile soil, loose soil texture, and a deep soil layer. The orchard should be well-ventilated and sunny, far from noisy areas, and have a good drainage and irrigation system. Before planting, spread some farmyard manure and trace-element fertilizers such as calcium-magnesium phosphate over the whole area, then carry out a full-orchard mid-tillage and hilling, mixing the fertilizer evenly with the soil. After plowing the land, begin making beds at a spacing of 8 m; an arched bed surface is most suitable. Each bed should have no more than four rows planted on it, with a distance of 2 m between rows and about 1 m between plants. About one month after land preparation, you can transplant the seedlings.
2. Reasonable close planting
To let Orah mandarins grow well and normally until fruit harvest, properly controlling the planting density at planting time is the most critical factor. But to achieve high yields, you need to use close-planting cultivation, generally planned close planting, that is, a planting method of dense first and sparse later. The early planting density should be about 2*1 m, with intensified management; then in the second year, trial fruiting begins, and in the third year, yield starts to increase. By the fifth year, you can begin alternate-row thinning and transplanting, increasing the density to 4*1 m, and then in the eighth year change the density to 4*2, after which no further changes are needed.
3. Early-stage management
The management of the orchard in the first two years after planting is very important. When the spring shoots of the young seedlings grow to 5 cm, begin topdressing, mainly with quick-acting fertilizer, that is, nitrogen fertilizer, applying it once every half month, in order to promote the growth rate of new shoots. When the new shoots grow to 20 cm, promptly pinch off their tips to promote branch differentiation. Try to let them sprout 3-4 times of new shoots in the first year, so that the canopy can be rapidly expanded. When fertilizing, you can use the integrated water-and-fertilizer method. In September, mainly use phosphorus and potassium fertilizers. In October, mainly use phosphate fertilizer and organic fertilizer. When fertilizing during the growing season, mainly use foliar fertilizer and trace elements.
4. Shaping to promote fruiting
⟦NL>Orah mandarins grow very fast, so in the first year after planting you should pay attention to training the tree shape. After planting the seedlings, immediately determine the trunk height, generally leaving about 30 cm and cutting it short, in order to promote branching. After the spring shoots stop growing, properly cut short the spring shoots that are more than 20 cm long. In summer, because the summer shoots grow unevenly, pinch off the tips of long branches of 20 cm to prevent excessive vegetative growth of long branches. Then, after the summer shoots stop growing, cut short the longer shoots, and spray some monopotassium phosphate on the leaves to promote shoot growth, then apply an appropriate amount of nitrogen fertilizer to promote the sprouting of new shoots.The above is a brief introduction to the planting methods for Orah mandarins. Orah mandarins are relatively difficult to grow, and growing them requires a certain level of skill. If the planting method is incorrect or management is inadequate, Orah mandarins will find it very hard to survive until the fruiting stage. Before planting, everyone must master its cultivation techniques, and also make decisions based on their own conditions and market demand. Do not plant blindly, otherwise the planting will ultimately be meaningless.
