Embodiment 1

[0016] Example 1 Preliminary Test

[0017] Test materials: Xiaoqiufeng, Huangchuan Jingui, and Daye Yingui, three varieties, two different specifications with a ground diameter of 5cm and 8cm, and open-air potted plants.

[0018] Test method: Set up a control group and only carry out routine management. In the test group, water replenishment was started when the temperature was higher than 30°C, and the infusion bag was used to slowly supply water around the root system, and the water replenishment was suspended in rainy days. During the experiment, three main physiological indicators were measured: peroxidase activity (POD), chlorophyll content (Chl), and electrical conductivity (RC).

[0019] The test results are shown in Table 1. Compared with the control group, the POD of the test group was relatively higher and the electrical conductivity was lower; in addition, the chlorophyll content of the test group was relatively stable and maintained at a high level, and the amount...

Embodiment 2

[0023] Embodiment 2 field test

[0024] Rent 20 mu of land in the Baima scientific research base of Nanjing Forestry University to carry out field experiments. Irrigation pipes are buried around the experimental field, the planting density is 4m×4m, and there are 50 trees of each variety and each specification. In the field experiment part, the control group and the test group are still set up, only the chlorophyll content is measured, and the number of fallen leaves (relative amount) is counted. The specific experimental method is as follows:

[0025] In mid-July, loosen the soil; when the temperature is higher than 30°C, hang the infusion bag on the trunk. The capacity and quantity of the infusion bag depend on the size of the osmanthus tree. Generally, the diameter of the osmanthus tree is 5 cm, and the capacity of the infusion bag is 2.0 liters. ; 10cm size, hang two infusion bags; 15cm size, hang 3 infusion bags. The other end of the infusion line is placed on the soil ...

Abstract

The invention discloses a method for preventing sweet-scented osmanthus leaves from falling in summer. The method includes the steps: 1) loosening soil around roots of sweet-scented osmanthus in the middle of July; 2) hanging infusion bags on a sweet-scented osmanthus tree trunk when air temperature is higher than 30 DEG C, placing the other ends of infusion lines on surface soil 20-30cm away from a trunk base, and determining the capacity and number of the infusion bags according to the specification of a sweet-scented osmanthus tree; 3) changing the infusion bags once a day, and filling the changed infusion bags with water from water injection holes for standby application. High-temperature damage to sweet-scented osmanthus in summer can be prevented, normal physiological metabolism of a tree body can be maintained and enhanced by scientific water supply, high-temperature resistance of landscape plants can be enhanced, and heat damage is relieved. Moreover, the method is rapid in effectiveness and wide in range of application and can be used for preventing the sweet-scented osmanthus leaves in courtyards and various urban gardens from falling in summer.

Description

technical field [0001] The invention belongs to the technical field of osmanthus cultivation, and in particular relates to a method for preventing osmanthus from falling leaves in summer. Background technique [0002] The vast majority of garden plant production is open field cultivation. However, open-field cultivation is greatly affected by natural factors. For garden plants that are not tolerant to high temperatures in summer, high temperature is an important factor affecting their ornamental effects. In mild cases, the edges of the leaves will dry up, affecting the normal photosynthesis of plants, and in severe cases, the tree body will be damaged. Lots of fallen leaves. Summer leaves are closely related to tree species, site conditions, and management. The performance is as follows: 1. Different tree species have different tolerance to high temperature in summer. Pine, cypress, eucalyptus, etc. have strong tolerance to high temperature in summer; tree species such as...
