What's the use of pear flowers? Pear is a common flower in our daily life. Pear is white and delicate, which not only produces delicious pears, but also has high ornamental value. In fact, pear flower has many other functions. Let me tell you the use of pear flowers.

What's the use of pear flowers? 1 1. For viewing.

Pear is a common flower plant in life, but many people don't know what it is used for. In fact, it is a very ornamental flower plant. The flowers are bright and white, which is more suitable for family potted plants. Putting it at home can make the indoor environment more beautiful and natural.

Second, clearing away heat and toxic materials.

Pear flower is not only very ornamental, but also has high therapeutic value. It can play a good role in clearing away heat and toxic materials when used as medicine. You can wash it with clean water and boil it in boiling water for a few minutes before drinking. It is also a necessary summer drink in hot summer, and has always been loved by many people.

Third, eliminating dampness and relieving cough.

Pear flower also has a good effect of eliminating dampness and relieving cough. Contains a variety of sugar conjugates, which can play a good role in assisting dietotherapy for symptoms such as high fever and tuberculosis. It can be used for drinking tea and cooking, and it is also the best health food for some middle-aged and elderly people, and also has a good protective effect on the throat.

Fourth, prevent cancer.

Many researchers said that pear flower contains many antioxidant substances beneficial to human body, which can inhibit the activity of human cells, thus playing a good role in preventing cancer. If you eat it regularly, it also has a good effect on the ventilation and intestines of the human body.

What's the use of pear flowers? 2. Key points of pear cultivation

First, planting density

Different planting densities and planting forms lead to different tree, aboveground and underground management measures, thus forming different cultivation management systems. The optimal cultivation management system should be that the leaf area coefficient increases rapidly in the young tree period, and the effective area of photosynthesis can still be maintained after entering the high-yield period, and it should be easy to manage. Sparse pear orchards bear fruit late and take effect slowly. Variable density design is to plant permanent plants and temporary plants at the same time, and it is better to plant 333 plants or11plant at 666.6m m. The distance between permanent rows and plants is 2m, and the row spacing is 5m: two temporary rows are planted in the middle of permanent rows 1m, and the row spacing 1m is 666. 333 plants can be planted in 6m. After planting for three years and four years, the fruit easily exceeds 1500 kg. If the small row spacing is 2m, the large row spacing is 4m and the plant spacing is 2m and 666.6m,11plant can be planted.

Second, fertilization.

Orchards planted in spring should be prepared in the first autumn. The digging diameter of permanent plants is 1 100 cm, and the depth is 80- 100 cm. Temporary plants with high planting density and small plant spacing can be planted in ditches with a width of 50-60 cm and a depth of 60 cm. Don't disturb the soil layer when digging holes and ditches, put the topsoil aside and the core soil aside, and pay attention to fill in the fertile topsoil around the rhizosphere first when backfilling. Soil miscellaneous fertilizer 15-25 kg and nitrogen fertilizer 50- 100 g should be applied to each plant. When planting trees, the topsoil and organic fertilizer are evenly mixed according to the ratio of 3: 1 and filled near the root system of seedlings. When the excavated soil is backfilled to 80%, it will be watered and compacted, and it will be sorted after the water seeps down. In late autumn and early winter, base fertilizer should be applied to ensure the nutrient supply of trees and the robustness of trees, so as to lay the foundation for high yield and income increase in the coming year.

Third, shaping and pruning

1, according to local conditions, determine the tree.

Different geographical environment and planting methods of pear trees determine different tree shapes.

Intensive cultivation with short stems can make the garden economy in front of the house slightly higher. In mainland China, evacuation and stratification are generally adopted, and scaffolding is used in some places where typhoon damage is serious in Fujian, Zhejiang and coastal areas. Pruning in areas with good soil quality should not be too heavy, and pruning in mountainous and hilly areas can be appropriately aggravated. At the same time, a layer of calluses antiseptic film should be attached to the trimming mouth to protect the wound healing.

2. Because of the shape of the tree, trim it with branches.

There are two kinds of pear trees: evacuation layered and multi-branch natural shape. Pear trees have strong polarity and weak branching power, and may not form an ideal tree shape according to people's wishes, but they can only be shaped by trees, and they cannot be forced to be consistent. Otherwise, it will affect the output.

3, the master-slave is clear and the structure is reasonable.

Pear trees are dry and need central leadership. It is also necessary to equip the central leadership with main branches, and the main branches are equipped with auxiliary branches. The central main branch is stronger than the main branch, the main branch is stronger than the side branch, the side branch is stronger than the secondary side branch growing on the side branch, and the growing branch is stronger than the fruiting branch. The main branches are evenly distributed around the trunk, and the growth between the main branches should be balanced. If there are two layers of main branches, there should be a certain distance between the second layer and the first layer. The two main branches on the second floor should be arranged in a direction that does not affect the lighting of the main branches on the first floor.

4, not only make full use of space, but also ventilate and transmit light.

Pear trees stand upright and are easy to form umbrellas, which affects ventilation and lighting. Pear trees have weak branching ability, which often leads to local emptiness. The vacant part should be compensated by measures such as pulling branches, dividing lateral buds and carving injuries. The branches and leaves are too dense to be solved by opening the window. Pear trees require more light. The quality of Dangshan crisp pear in Gansu is better than that of Anhui, its origin. One of the important reasons is that the lighting conditions in northwest China are better than those in Anhui. In order to solve the lighting problem, pear trees are required to be large and small, with no umbrella, no landing and no air.

5. Control and promote, control the strong and help the weak.

Pear trees with strong polarity often lead to hollowness, so we must pay attention to controlling the upper part and promoting the growth of the lower part. Control the strong part, support the weak part and achieve balanced growth.
