Cultivation of Huanghua Pear

With the decrease of natural Huanghua pear, more and more Huanghua pears are planted artificially. What is the planting method of Huanghua pear?

Cultivation of Huanghua Pear

1. Huanghua pear is suitable for planting in spring, it is a positive tree species, the site condition is not strict, and the planting soil is suitable for lateritic red soil or brown latosol.

2. It is most suitable to sow Huanghua pear seeds from March to May and November to December every year. However, the temperature and climate are different in different places, such as Guangxi, Guangdong, Fujian and other places have more Rain Water in spring, it is appropriate to sow in March-May, Hainan planting season will be relatively late, generally late autumn or early winter is the best. Plant according to the local climate characteristics.

3. Before sowing, the seeds need to be soaked in clean water for more than 12 hours to accelerate germination and improve the germination rate. Sow evenly or on demand in the soil, if the seeds overlap and rot easily, you need to pay attention when sowing, then cover the sandy soil around 1cm and water twice a day to keep the soil moist.

4. It is best to cut in March every year. Before cutting, the cuttings are first soaked in 1000-fold chlorothalonil solution for 5 minutes, and then soaked in 0-6 indole butyric acid rooting solution for 6 hours. After taking out the cuttings, the rooting rate can reach more than 25010 after careful management.

5. When cutting, first punch holes in the sterilized cutting bed with a stick slightly larger than the cuttings, and punch holes vertically according to the row spacing of 8 cm × 8 cm on the cutting bed, with a depth of 68 cm, which is equal to the depth of the cuttings into the soil. Then insert the cuttings into the hole, after the cuttings are pulled out of the soil, at least 2 or more bud holes should be retained on the soil surface, and then the cuttings should be compacted with fingers or sticks, and then immediately watered and fixed.

6. After cutting, the canopy should be set up to shade the light, and water should be sprayed regularly so that the surface of the cuttings will be moist. After the ear strips take root and become seedlings, we should pay attention to the timely selection of the trunk, remove the excess tillers, lateral branches and lateral buds, and then open the sunshade net after the seedlings grow normally and gradually let the seedlings grow in full light.

7. In the growth process of young trees, traditional Chinese medicine is used to loosen the soil, weed and fertilize in time. Combined with soil loosening, weeding and hole expansion, 150-200g compound fertilizer was applied to each plant in order to promote the growth of trees, make them close into forests as soon as possible, and reduce weeds.

8. Generally irrigate 3-5 times a year, respectively in the week before flowering, the spring shoot flourishing period and the fruit expansion period. When irrigation, avoid the warm noon, should be carried out in the morning and evening.

9. Huanghua pear has low branches and strong lateral branches. attention should be paid to pruning branches and cultivating good rod shape. However, it should be noted that in the first-2 years of the young forest, do not cut off all the lateral branches too early and excessively. It is necessary to leave more branches and leaves to increase photosynthesis. With the growth of the tree age, the young forest gradually grew taller and then gradually pruned upward. In this way, it is beneficial to increase the photosynthesis of the leaves of the young forest, and contribute to the growth of the young forest and the development of the root system.

10. The withered branches and rotten leaves in the garden were removed in time, and then chemical and physical measures were used to control diseases and insect pests.

Natural trees grow slowly, while artificially planted trees grow fast. It takes some patience to plant this kind of tree.
