Key Points of Mango Grafting and Seedling Cultivation Techniques
1. Selection of scions: Collect scions from a certified mother stock orchard or from superior individual trees of mature mother trees. The mother trees must be of pure variety, high and stable yield, good quality, and free of quarantine pests and diseases. Where conditions permit, nurseries should establish scion orchards specifically for collecting scions. Select branches from the outer periphery of the canopy exposed to sunlight, vigorous, well-developed, with plump buds, and free of pests and diseases - 1-year-old or 2-year-old mature lignified branches. Generally, autumn grafting uses current-year spring and summer shoots, while spring and summer grafting uses last year's autumn shoots or current-year spring shoots. Branches that are flowering, fruiting, or have just finished fruiting, as well as shaded weak branches, are not suitable for scions. Leaves can be removed 10-15 days in advance; after the petioles drop off, soak the collected scions in 1000 times carbendazim solution for 3 minutes, then air-dry before grafting immediately, which can improve the survival rate. Collected scions should be grafted promptly; if kept for more than 3 days, they must be stored at low temperature with moisture retention. If scions are collected from other locations, bundle them well, wrap with wet paper or wet cloth, and place in a cardboard box lined with plastic film. During transport, protect against sun exposure and heat buildup or dehydration and shrinkage.

Pollution-free mango seedling cultivation method
How are pollution-free mango seedlings grown? What methods are there? Pollution-free mango seedling cultivation methods: 1. Seed pretreatment: Collect locally grown mango fruits or seeds (polyembryonic varieties), such as Zhanjiang native mango, Hainan native mango, Guangxi almond mango, Yunnan small mango, Fujian red flower mango; monoembryonic varieties are suitable for use as seed. Remove the flesh from the collected fruits, rinse them clean with water, and discard seeds that float and those with soft or shriveled seed shells. If seeds are collected from other places, process them at the collection site, sun-dry the qualified seeds until the seed shells are dry, then mix in coconut coir, charcoal powder or fermented sawdust for moisture-retaining transport; after transport back, treat the seeds as locally collected fruits by shelling and sprouting, then air-dry. Seeds used for mango rootstock should come from seeds of mature, plump fruits eaten from vigorously growing trees. In production, seeds left over from processing are also used, or even large quantities of plump fruits are purchased and piled until rotten to extract the seeds; after the seeds are extracted, immediately wash off the flesh, air-dry, and sow right away. Sowing must be completed within 7 days, otherwise the germination rate will be affected.
