The latest course of seed breeding techniques and methods of Mango

Mango is one of the hot fruits in summer, and it is more loved by consumers in the market. When mango is planted and produced, its reproduction can be done through sexual reproduction and asexual reproduction. Among them, sexual reproduction is seed reproduction, so how to carry out it? Come and have a look with the editor.

1. Land selection and preparation

The nursery land should be close to the water source and shelter from the wind, and the sandy loam soil with deep soil layer, rich in organic matter and good drainage should be selected as the nursery land, while the heavy soil, easy consolidation and shallow soil layer should not be used as the nursery land. The nursery land should be fully cleaned, shaped and raked flat, high beds should be made according to the topography, and drainage ditches should be opened, with a length of 10 meters, a width of 80-100cm, a high 20cm and a 40-50cm interborder. Mango has deep roots, so it is necessary to apply sufficient basic fertilizer before planting to ensure the healthy growth of seedlings. 30004000 kg of mature animal manure or compost should be applied per mu, which can be spread, ditched or burrowed.

2. Seed treatment

The seeds should choose the varieties with strong affinity suitable for the local environment, the mother trees with high yield and strong strength, and the fruits with medium size, full body and correct fruit shape. After removing the pulp, you should know how to wash the pulp on the core and shell, remove the floating planting, and place the seeds in the sun until dry. Do not expose the seeds to the strong light for a long time, so as not to affect the germination.

3. Peeling and budding

After the seed has been treated, it will begin to germinate. Because the shell of the mango seed is hard, it will hinder the seed germination, so it is necessary to peel the seed and be careful not to damage the kernel inside. Place the kernels on the sand bed and arrange them one by one, requiring the navel to be downward and the seed spacing 3-5cm apart. After sowing, 1-2cm should be covered with fine sand and watered once. After that, it should be watered once a day to keep the sandy soil moist. The seedlings will emerge in about 12-15 days, and the seedlings will grow in about 20 days.

4. Seedling stage management

The seedlings should be moved in time and the row spacing should be controlled. The whole root of the seedling with seed kernel should be dug out with a bamboo stick and transplanted in the seedling bed, and the root system should be damaged when the seedling is raised. If the main root is too long, it can be cut off properly, but it should not be shorter than 10cm. The purpose of transplanting is to make the root system of the seedling stretch, plant depth flat with the root neck, backfill fine soil, make the root system closely connected with the soil, and water the seedling in time to increase the survival rate. Mango seedling stage is during the period of high temperature, sometimes accompanied by drought, so in order to avoid water and cause seedling death, it is necessary to water according to the dry and wet condition of the soil, replenish moisture and replenish soil moisture. In order to ensure the nutrients needed for the growth of seedlings, topdressing should be applied in time after shoots are drawn. Thin manure can be applied to increase the concentration with the growth of seedlings.
