1. After the orchard planning and reclamation is selected, roads, irrigation and drainage ditches, shelterbelts, soil and water conservation, etc. should be rationally planned and laid out before reclamation. The reclamation time should end two months before the fixed value, and the flat gardens below 0.5 should be marked with a "cross", with a plant spacing of 5 m and a row spacing of 7 m, and the plant rows should be marked straight and perpendicular to each other; On the slope above 5, we will build terraced fields with row spacing of 7 meters, width of 3-4 meters, plant spacing of 5 meters, and plant 20 plants per mu.
2. Dig a fixed hole, the hole width x depth x bottom width is 80 cm x 70 cm x 60 cm, and the topsoil and raw soil are stacked separately. At the same time, 30 kg of farmyard manure, 5 kg of ternary compound fertilizer 1 kg and calcium magnesium phosphate fertilizer were fully mixed with the topsoil of each hole, and the hole surface was 10-20 cm higher than the ground.
3. Selection of seedlings Because the cultivation and grafting of macadamia seedlings have strong professional skills, great difficulty and high investment cost, there is generally no need for self-propagating and self-supporting seedlings. Grafted seedlings must be selected, and robust bagged seedlings with strong plants, obvious graft healing parts, dark green leaves, no pests and diseases, well-developed roots, trimmed central branches, slightly longer than 30 cm and higher than 50 cm, and secondary germination and growth of branches and leaves must be selected.
4. Variety Selection At present, macadamia varieties with high yield, high efficiency and high quality suitable for planting in Jiangcheng area mainly include 0c, h2, OC, 344 and 294. Planting 4-5 varieties in an orchard is not suitable for planting a single variety in an orchard.
5. The planting time is usually fixed in July-August every year.
6. Planting method When planting, mix varieties according to 1: 1 or 2:2. Returning soil by layers makes the soil in good contact with the root system, compacts it from the inside out, and irrigates the root water thoroughly.
