What if the happiness tree only grows tall and not thick?

Happiness trees only grow tall but not thick, and the top of the main pole can be sawed off.

Maintenance and management technology of happiness tree

Planting the happy tree after frost and defoliation in early autumn or before germination in spring; Green seedlings can be transplanted in spring, summer and autumn, and the roots need to be transplanted with soil during the growing period. Roots should be introduced before early May or after the middle of 10, and seedlings and green seedlings should be introduced before the end of April or after the middle of 10.

postulate

1, soil requirements: acid soil, neutral soil and light alkaline soil can be cultivated, and soil with PH value between 4.5 and 8.5 can be cultivated and grow normally; Choose sandy loam with deep soil layer and cultivated land with low groundwater level, with good drainage, no source of plant diseases and insect pests, convenient transportation, good irrigation conditions and flat terrain.

2, cold and heat resistance: it can not freeze at a low temperature of MINUS 33 degrees; The weather in the south is hot and the growth rate is faster.

3. Cultivation time: the happiness tree is cultivated after frost and defoliation in early autumn or before germination in spring; Green seedlings can be transplanted in spring, summer and autumn, and the roots need to be transplanted with soil during the growing period. Roots should be introduced before early May or after the middle of 10, and seedlings and green seedlings should be introduced before the end of April or after the middle of 10.

Seedling management

1, plant spacing: plant spacing greater than 60 cm, plant spacing greater than 70cm；; Seedlings should be planted within 0/000 plants per mu/kloc.

2. Transplanting: The transplanting of happiness trees should be carried out after defoliation in autumn or before germination in spring, and the planting time should be determined according to the local temperature conditions. The lowest temperature in spring can reach MINUS 10 degrees, and it can be transplanted after the first frost in autumn; One year, the seedlings grow vigorously after cutting (leaving 20 cm) and transplanting.

3. One-year-old and two-year-old seedlings need to dig holes, the length, width and depth are 40cm respectively. For large-sized seedlings, the digging size should be increased appropriately, and the soil layer should be isolated 15-20cm after fertilization at the bottom of the pit (the ratio of base fertilizer to potassium fertilizer is 2: 1, and the dosage is appropriate); Put the saplings in and fill them with water (depending on the soil humidity), and then fill them with soil after the water sinks; Water in time in arid areas to keep the soil moist.

4. Seedling management: The lateral center of the seedling should be picked before the seedling grows to 3 cm to ensure the rapid growth of the trunk. When the trunk length is 180 cm, side branches should be left. When the trunk grows to 250 cm, the middle part of the trunk should be picked and fixed to meet the needs of greening street trees. Timely fertilization and weeding to prevent the occurrence of pests and diseases.
