How to grow wampee seedlings? The latest seedling cultivation techniques and methods tutorial
The wampee tree is a tree species with relatively high economic value. Its planting advantages are quite obvious, and its yield is high. The average yield per mu is 3000-4000 jin, and it takes only a short half month from flowering to fruiting, requiring low labor costs. To grow wampee, seedling cultivation is extremely important. Now let's take a look at the wampee seedling cultivation techniques with the editor.
1. Rootstock cultivation
Take seeds from large, many-seeded, fully mature wampee fruits. Wash the pulp and cuticle clean, dry them in the shade, and then sow. Fresh seeds have a high germination rate, while dried seeds will reduce the germination rate, so never expose them to strong sunlight. There are two sowing methods. One is direct sowing, sowing the seeds at a certain spacing between plants and rows, or sowing them in nutritional pots. This kind of seed benefits from soaking and germination promotion before production; sow when the seeds show white or the sprouts are within 1 cm long. The other is broadcast sowing. Choose fertile, well-drained land, make beds, level them, or build a sand bed in the nursery, then broadcast sow with a seed spacing of 3~4 cm. After sowing, cover with 1 cm of loose fine sand, cover with grass, and water to keep moist. After the seedlings emerge, remove the grass, strengthen fertilizer and water management and pest and disease control. When the seedlings grow to 10-15 cm in the following spring, transplant them.
2. Grafted seedling cultivation
When the rootstock diameter reaches 0.5 cm, grafting can be done. Grafting can be divided into spring and autumn. Grafting methods include approach grafting, cut grafting, cleft grafting, and patch budding. Approach grafting is carried out from March to June each year, but the survival rate is highest around Qingming; cut grafting and cleft grafting are done in March-April. Take scions from the current-year spring shoots or autumn shoots that are full and mature on the outer part of the middle-upper canopy of superior mother trees, and graft at 15-20 cm above the ground on the rootstock. Patch budding is generally carried out in summer and autumn. Open a bud grafting position on the main trunk of the rootstock at about 30 cm above the ground. The bud grafting opening is generally larger than the bud patch, then cut the bud patch and insert it into the bud grafting opening, then tie it tightly with plastic film. When the cut heals, remove the plastic film promptly.
3. Orchard establishment and planting
The planting site should be in an area with an average temperature above 20°C. The soil should be loose and well-drained, preferably close to a water source. Avoid planting on heavy, compacted, or dry land. Field planting is mainly in March-April or September-October, and it is best to use mature seedlings. The planting density depends on the management method, soil, and configuration characteristics. Generally, 66 plants are planted per mu. Before planting, dig the holes and apply sufficient base fertilizer. When planting, backfill with topsoil, green manure, farmyard manure, and poultry and livestock manure mixed with calcium fertilizer, magnesium fertilizer, and phosphate fertilizer. Each layer must be mixed evenly with soil, and finally backfill soil to 15 cm above the ground.
