Step 2 soak. Soak the selected seeds in warm water for 24 hours to soften the epidermis. After 24 hours, put it in a towel to dry the water inside, and then soak it in clear water for about 5 days. In order to make the germs sprout and take root faster, change the water once a day. If it takes more than 5 days or too long, the seeds will rot and die.
3. sow. Put the soaked seeds into the pot soil, and the pot soil should also ensure a certain permeability. The soil should be the original mud in the forest, seeds should be pressed in it, and some rotten wood and pebbles should be added to the surface to better drain water. Then, all the pots should be covered with soil to ensure adequate lighting conditions every day. Remember that it is not suitable for exposure in the sun.
4. Fertilize. There is also a great demand for fertilizer for orange seeds, because the roots of new orange seeds metabolize quickly and need more nutrients, about once every two weeks, and the soil should be washed once a week, otherwise the roots can't absorb nutrients because the soil is dry, but it can't be too frequent. Then put it in a mild temperature environment and give sufficient sunshine conditions, so that the leaf epidermis will grow.
5. Soil quality requirements. Many methods of planting orange seeds are at a loss. In fact, the first is the requirement for soil, and orange seeds also have high requirements for soil. In order to choose the decomposed matrix soil of primary forest, loam with granular structure is the best, because according to the growth habit of oranges, it is best to have decomposed soil, manure, forest soil and coarse sand in the ratio of 2: 1:2: 1.
6. Moisture requirements. For nutrients, it is also necessary to observe the dryness of the soil every day. Water can be watered once every two days in spring and autumn1~, and once every three to five days in autumn and winter. You can't water too much or too little. Effective absorption of roots is the most important. You can't accumulate water in the basin soil, but put it in a ventilated place.
7. Trimming and shaping. If there are many lateral branches, it can be shortened, and each main branch keeps about 2 ~ 3 lateral branches. When the seedlings grow, they should be cut lightly and should not be overweight. It is important to better ensure the growth balance of each main branch. Long branches at all levels should be treated at flowering stage, and water should be controlled by ring cutting in autumn, and weak branches, dead branches, pests and diseases should be cut off at fruiting stage.
4. Lighting conditions. Orange seeds are generally placed in sunny places, but they should not be exposed to the sun for a long time. It is best to sow in spring, autumn and winter, because the summer temperature is too high, which will affect the growth and development of seedlings, so sowing in summer is best cautious. The indoor temperature should be kept at about 20℃, neither too high nor too low.
