How to Grow Shasatang Mandarin for High Yield? Latest Technical Method Tutorial
We are all familiar with Shasatang mandarin; its taste is relatively sweet, it has among the higher sweetness levels of citrus, and its texture is delicate with no residue after eating, making it extremely popular with consumers on the market. However, due to limitations of region and climate, its planting area is limited, and in the face of growing market demand, the only way is to start with yield, so how can Shasatang mandarin achieve high yield? Let us take a look at the high-yield cultivation techniques for Shasatang mandarin.
1. Seedling selection
To achieve high yield, the first step is to select pure-variety, disease-free and pest-free strong seedlings. In addition, early-maturing varieties have better variety traits and yield, and grafting techniques can also be used to take advantage of the variety's strengths. Seedlings using trifoliate orange as rootstock have dwarfed plants, high fruiting and relatively high yield; seedlings using sour mandarin as rootstock have tall, upright tree shapes and bear fruit relatively late. Therefore, the graft union height of the seedlings is required to reach 0.6 cm, the height must reach 50 cm, and it is best to have more than 3 complete branches with a complete and undamaged root system, so that high-quality varieties can be grafted.
2. Reasonable close planting
Shasatang mandarin itself has the characteristics of early bearing and high yield, so reasonable close planting and planned use of early-stage land can increase the orchard's yield through this method, generally doubling the yield. When planting, choose a loose, fertile and moist soil environment, planting 200-300 plants per mu, with a plant-to-row spacing of about 2×1.5 m. In addition, practical production has shown that dwarfed close planting is also an important technique for achieving early fruiting and high yield.
3. Management during the young tree stage
The stage from planting to flowering is the young tree stage, generally lasting 2 years. At this time, what needs to be done is to strengthen tree nutrition, cultivate the canopy and root system, and carry out reasonable pruning. After field planting, pruning should be carried out, leaving 5-6 short branches on the main branches, strengthening fertilizer and water management to promote new shoot sprouting. After the new shoots sprout, select 3-4 shoots with consistent growth and even distribution as auxiliary main branches. After the new shoots mature, cut them back again to promote shoots, repeating this multiple times to form the canopy. Summer is the peak growth season for young trees, so in order to bear fruit earlier, bud removal should be carried out to promote shoots, so that summer shoots emerge uniformly. In the second year, the main task is reasonable pruning to expand the canopy. In addition, the fertilizer amount during the shoot period should be more than double that of the first year, promoting early formation of the canopy.
4. Management during the fruiting stage
After management during the young tree stage, the canopy of Shasatang mandarin has basically taken shape. It begins to bear fruit in the third year, and reaches full fruit production in the fifth year. The most important thing during this period is measures to protect flowers and fruit. Shasatang mandarin produces a large number of flowers, but is very prone to flower drop, so foliar fertilizer should be sprayed in time during the flowering period to protect flowers. The foliar fertilizer is mainly made by mixing borax or monopotassium phosphate with water to form a solution for spraying. In addition to flower drop, Shasatang mandarin also has two natural physiological fruit drop periods, especially the second physiological fruit drop, which is greater. At this time, after most flowers have faded, spray gibberellic acid throughout the orchard to protect fruit. When physiological fruit drop is still relatively serious, ring cutting can be carried out to promote flower bud differentiation and improve fruit quality.
