Huanghua pear planting and cultivation techniques Huanghua pear is a precious wood with the characteristics of non cracking, fine structure, corrosion and moisture resistance, and a special aroma. It is a precious wood for making furniture and handicrafts. Let's learn about Huanghua pear planting and cultivation techniques together.
1. Site selection and land preparation
Before cultivating Huanghua pear, it is necessary to choose a suitable soil environment. Based on the characteristics of Huanghua pear, which prefers light and deeply rooted, a sunny hilly area can be chosen. The nursery should have a flat terrain, good drainage and irrigation conditions, sandy soil, fertile soil layer, and a flat surface without standing water. Before 10 days of seedling cultivation, fertilization should be stopped and the frequency of watering should be reduced, and medication spraying for disease and pest control should be done well. During cultivation, do not tear the nutrient bag, keep the seedlings straight and compact the soil.
2. Choose a good variety
Choose plants with normal development, robust growth, and no pests or diseases as the mother tree. The harvest time is in December, when a large number of Huanghua pear fruits mature and the yellow green skin turns yellow brown, making it a suitable time for harvest. Long term storage of Huanghua pear seeds can affect the germination rate, so they can be harvested and sown as needed. Incomplete ripe fruits should be manually selected and placed in a cool place. After they mature naturally, they should be treated as ripe fruits.
3. Seedling cultivation
Before sowing, the soil should be disinfected, and it is recommended to do so one week before sowing. High temperature disinfection can be used to disinfect the seedbed. Dry grass or leaves can be evenly spread on the seedbed, ignited and incinerated. On the second day, the soil can be deeply turned over, and then spread and incinerated. This can have the effect of high temperature sterilization and killing larvae, as well as increasing soil fertility, and the cost is relatively low. Medications such as formalin, ferrous sulfate, carbendazim, etc. can also be used to disinfect the seedbed by watering it thoroughly one week before sowing. Before sowing, the seeds should be soaked in clean water for 24 hours to promote germination, then removed and air dried. When sowing, the seeds should be evenly spread on a disinfected seedbed and covered with a layer of fine soil. Use a shading net to block sunlight or cover a layer of thin grass. After sowing, water should be sprayed in the morning and evening to ensure that the seedbed is moist. After half a month, the germination rate of fresh and full seeds can reach 90%. Before emergence, it is necessary to ensure sufficient irrigation water, and the soil after sowing should be moist. Generally, irrigation should be done once within 5 days before emergence, and it is not necessary to irrigate on rainy days. Pay attention to drainage.
4. Migration Management
After 3 to 4 months of cultivation in nutrient bags, Huanghua pear seedlings can be planted in the nursery. To improve the survival rate of seedlings, it is necessary to refine them before leaving the nursery. When refining seedlings, remove the sunshade to allow the seedlings to grow under light, minimize water supply, and no longer fertilize. Move the seedlings in place, cut off the root system, cut off some branches and leaves, reduce water consumption, and thus improve the survival rate of the seedlings. When raising seedlings, most of the branches, leaves, and excessively long roots should be cut off. When leaving the nursery, soil should be used to cover the roots. Grade the seedlings and cultivate them separately according to their height, height, thickness, and fineness. Unqualified seedlings should continue to be nurtured in the nursery.
5. Parenting management
To do a good job in nurturing management, during the seedling nurturing process, observe the growth of the seedlings after 30 days of planting, and supplement the missing parts of the seedlings to ensure a regular growth state of Huanghua pear. Then, fertilize the seedlings well. Finally, for the pruning of the branches of Huanghua pear, the planting of tree species should be manually pruned to ensure the healthy growth of Huanghua pear, which is beneficial for its formation and growth.
6. Prevention and control of pests and diseases
The main diseases during the seedling and sapling stages of Huanghua pear include black spot disease, anthracnose, etc. Both black nevus and anthrax are mainly prevented. In daily management, timely watering and fertilization are necessary to improve plant resistance, prune and shape branches, remove weeds, and ensure ventilation and transparency. When diseases occur, 70% Daisen manganese zinc wettable powder can be used, sprayed every 5-7 days, 2-3 times in a row. Sudden seedling wilt disease is a disease caused by fungal infection in seedlings, which leads to the decay of sprouts, the death of upright seedlings, and the lodging of seedlings. The prevention of seedling collapse disease is the main focus. When raising seedlings, it is advisable to choose well drained, ventilated, loose and fertile land to reduce the probability of fungal infection in seedlings.
The main pests are longhorn beetles. Attention should be paid to preventing longhorn beetles from penetrating the heart and preventing young trees from being damaged or withered by wind. During the larval stage of longhorn beetles, 90% trichlorfon can be used, using an animal syringe to inject through the insect hole and sealing it with a cotton ball to suffocate it. Other pests can be controlled using conventional methods. Young locusts, leaf eating beetles, and other insects often appear in summer, and can be controlled by spraying 90% Dichlor on the canopy leaves.
