Sausage is a warm-loving tree species, so it can't grow in freezing areas. The optimum temperature for growth is 23-32℃, and the lowest temperature for tolerance is -3℃. Sausages usually grow well in the south of China, and the propagation of sausages is generally by sowing. Stored seeds are often sown in spring, and fresh seeds can be sown in autumn.

1, seedling stage

When the seeds sprout, remove the plastic film and cover it with 50% shading net, which is beneficial to ventilation and light transmission, and pay attention to watering to promote the normal growth of seedlings. When the seedlings grow 1-2 pairs of leaves, remove the shading net and let the seedlings grow in natural light. After the seedlings grow true leaves, according to the growth of seedlings, 5 g/L compound fertilizer aqueous solution can be used for fertilization 1 time every week, and the fertilization time should be carried out in the morning, and then the seedlings should be drenched with clear water in the afternoon. When the seedlings are long enough for transplanting, stop fertilizing.

Step 2 plant

The survival rate of sausage saplings planted before germination in spring is relatively high. If you choose to raise seedlings in spring, by the next spring, the seedlings will have grown to about 50 cm, so they should be transplanted to the field in time for planting. The planting site is sandy land, with fertile soil, no stagnant water and convenient irrigation and drainage. Plant spacing depends on topography and cultivation purpose. Generally, 2m× 2m is selected, and the hole size is 50cm× 40cm× 30cm. Apply 3-5 kg of decomposed farmyard manure or 0.25 kg of compound fertilizer mixed with topsoil to each hole. It is best to choose rainy days for planting. After planting the seedlings, gently lift them after covering the soil to stretch the roots, which is practical. Fill should be slightly higher than the ground to prevent water accumulation. When planting in sunny days, water your feet.

Step 3 take care of

After planting, loosen the soil and weed in spring and autumn every year 1 time, and topdressing 1 time. Compound fertilizer is selected as the fertilizer, and the fertilization amount is 250-350kg/hm2. Before the rainy day comes, spread the fertilizer evenly on the ground. If you choose to apply fertilizer in sunny days, irrigate the fields in time after spreading fertilizer. Young trees grow fast and the tree shape is irregular. When the young trees grow to about 1 m, support frames should be set up in time. Pay attention to pruning and shaping to improve the viewing effect. Pruning time should be chosen after flowering, not in spring. Generally, seedlings cultivated for 3 years can be used for landscaping.
