Three key points to note when growing Huanghuali pear trees

The pear is a fruit we often see and one that many people love. The Huanghuali tree is a type of tree that produces sweet, fragrant pears. Below, let's take a look at how to grow Huanghuali trees so they bear an abundance of fruit.

I. Propagation methods for Huanghuali trees

1. Cuttings are best taken in March each year; in other seasons, the survival rate of cuttings is lower and the cost is higher. The best time of day for taking cuttings is in the evening. Before taking cuttings, first soak the cuttings in a 1000-fold dilution of chlorothalonil solution for 5 minutes to disinfect them, then soak the base of the cuttings in a 25010-6 indolebutyric acid rooting solution for 6 hours, then remove the cuttings; they must not be inserted upside down. After careful management following insertion, the rooting rate can reach more than 80%. The use of other rooting concentrations for cuttings should be determined after further trials. Otherwise, too high a concentration will inhibit rooting of the cuttings. If it is difficult to buy a rooting agent or none is available, you can soak the lower end of the cuttings in a 5% sucrose solution for 12 hours, then remove the cuttings and insert them; treating cuttings this way also gives a fairly good rooting effect.

2. When taking cuttings, first use a wooden stick slightly thicker than the cutting to make holes in the already disinfected cutting bed or nutrient bag. On the cutting bed, make vertical holes at a spacing of 8 cm x 8 cm between plants and rows, with a depth of 68 cm, equal to the depth at which the cuttings enter the soil. Then insert the cuttings that have been treated with the solution into the holes. After the cuttings are pulled from the soil, at least 2 or more buds should remain above the soil surface. After insertion, press the holes firm with your fingers or a small wooden stick, then water immediately to settle the plants.

II. Pruning principles for Huanghuali trees

1. In the process of developing the canopy, whether cultivating fruiting branch groups or maintaining the fruiting capacity of fruiting branch groups, some branch groups must be controlled while others are developed. Under normal circumstances, branch groups on the upper side should be properly controlled, while for lateral branch groups, strong branches need to be selected and retained as extension branches and encouraged to develop, so as to help moderate tree vigor and stabilize the branch groups. During pruning, attention should be paid to the rational arrangement of large, medium and small branch groups. When tree vigor is relatively strong, cultivating an appropriate number of large branch groups helps retain more medium and small branch groups; maintaining an appropriate number of development branch groups is what helps stabilize the other branch groups.

2. Maintaining the compact structure of twining branch groups is a necessary condition for stable, high yields, but paying attention only to treating the branch groups themselves makes it difficult to achieve good results. Only by allowing some branch groups with room to develop to grow year by year can the branches of another part of the branch groups be kept compact.

3. The density of branch groups cannot be controlled simply by thinning or renewal pruning. On trees with vigorous growth, even if winter thinning is very heavy and the branch groups look sparse, because the number of branches is high, the vigor of the branch groups is unstable; once branches and leaves grow, they will affect the ventilation and light conditions inside the canopy.

III. Pest and disease control for Huanghuali trees

1. Pear scab: entering July, pear scab begins to infect the fruit. In the early stage of fruit infection, pale yellow spots appear. After the lesions expand, they become slightly sunken and bear black mold; later the lesions become corky and cracking appears. Control measures: spray 1:2:200 Bordeaux mixture during the young fruit stage; 21% Qiangli Kejunxing 1000-1500-fold solution, etc.

2. Pear powdery mildew: it mostly damages old leaves, generally with multiple lesions on each leaf; later yellow dots form within the lesions and gradually turn black. When severe summer drought is suddenly followed by heavy rain, this disease is prone to becoming epidemic. Control measures: in mid-July spray polyoxin 1000-fold solution; Dabao 1200-fold solution; 20% triadimefon emulsifiable concentrate 1500-fold solution.

3. Oriental fruit moth: the 1st-2nd generation larvae of this pest mainly damage shoot tips, while from the 3rd generation onward they mainly damage pear fruit. The fruit-boring hole of the oriental fruit moth is small and not easy to find, but the exit hole is large and obvious. Control measures: from mid to late July begin spraying the water-based formulation Green Kung Fu 3000-fold solution; mieyouniao 3000-fold solution; Lorsban 2500-fold solution, etc.

4. Pear weevil. July is the period when pear weevils damage fruit, often causing large numbers of infested fruit to fall to the ground. Control measures: manually pick up the fruit damaged by pear weevils, and spray 2.5% miesaoli emulsifiable concentrate 2000-fold solution or Jianmie 3000-fold solution for control.

The above is an introduction to the main points of growing and caring for Huanghuali trees. After reading the above introduction, do you now have a relatively clear idea of how to grow Huanghuali trees? If the answer is yes, then do not hesitate any longer. Hurry and try planting a Huanghuali tree; it can both green the environment and provide edible fruit.
