Detailed Guide to Mango Seed Propagation Techniques to Help You Grow Strong Mango Seedlings
Mango is one of the popular fruits in summer and is relatively favored by consumers on the market. When growing and producing mangoes, its propagation methods can be sexual propagation and asexual propagation. Sexual propagation is seed propagation, so how exactly should it be done? Follow the editor to take a look.
1. Site selection and land preparation
The nursery site should be close to a water source and in a sheltered environment. It is best to choose sandy loam soil with deep soil layers, rich organic matter, and good drainage as the nursery site. Heavy clay soil, soil prone to hardening, and shallow soil layers are not suitable for a nursery site. The nursery site should be thoroughly cleared, leveled and raked, made into high beds according to the terrain, and drainage ditches should be dug. The beds should be 10 m long, 80-100 cm wide, and 20 cm high, with 40-50 cm between beds. Mango has a relatively deep root system, so sufficient base fertilizer must be applied before planting to ensure strong seedling growth. For each mu, 30004000 kg of decomposed livestock manure or compost should be applied, either by broadcasting, trenching, or hole application.
2. Seed treatment
For seeds, choose varieties with strong compatibility with the local environment, select high-yielding and robust mother trees for collection, and choose fruits of medium size, plump, and with a regular shape for seed use. After removing the flesh, the seeds should have the flesh on the shell cleaned off, and floating seeds should be removed. Place the seeds in the sun to dry until they are dry, but do not expose them to strong sunlight for a long time, so as not to affect germination.
3. Shelling and germination promotion
After the seeds are treated, germination promotion should begin. Because the outer shell of mango seeds is relatively hard and will hinder seed germination, the seeds should be opened. When shelling, be careful not to damage the seed kernel inside. Place the seed kernels on a sand bed, arranging them one by one, with the hilum facing downward, and space the seeds 3-5 cm apart. After sowing, cover with fine sand 1-2 cm thick, water thoroughly once, and then water once a day to keep the sand moist. Seedlings emerge in about 12-15 days, and full emergence occurs in about 20 days.
4. Seedling stage management
When the seedlings have emerged uniformly, transplant them in time and control the plant and row spacing well. When transplanting, use a bamboo stick to dig out the seedlings together with the seed kernel and the whole root, and transplant them into the seedbed. When lifting the seedlings, be careful not to damage the root system. If the main root is too long, it may be appropriately trimmed, but it should not be shorter than 10 cm. When transplanting, the seedling roots should be spread out, the planting depth should be level with the root crown, and fine soil should be backfilled so that the roots and soil are closely connected. Water promptly after transplanting to increase the survival rate. The mango seedling stage occurs during a period of high temperatures, sometimes accompanied by drought, so in order to avoid seedling death caused by lack of water, water according to the moisture condition of the soil, replenish water, and keep the soil moist. To ensure the nutrients needed for seedling growth, after the seedlings sprout new shoots, topdressing should be done in time. Diluted manure water can be applied, and the concentration should be increased as the seedlings grow.
