In recent years, the phenomenon of falling flowers and fruits of persimmon trees has become a common problem, and in severe cases, it can cause no harvest. In response, the reporter interviewed Zhang Zhongqi, a senior agronomist engaged in the introduction and cultivation techniques of persimmon trees. Zhang Zhongqi said that in the summer, the prevention of persimmon trees should pay attention to the following aspects:
First, ring stripping For adult fruit trees, a circular stripping is usually carried out at the beginning of summer. The purpose of ring stripping is to prevent the nutrients produced by persimmon leaves during photosynthesis - the transport of carbohydrates to the roots is beneficial to the fruit.

Second, the thin fruit persimmon in early June, sweet persimmon from the beginning of June to the beginning of July, after the end of the physiological fruit drop, according to the ratio of 20-25 leaves with a fruit, select the healthy young fruit without pests and diseases, to be removed It is a fruit with a deformed fruit, pests and diseases, and a fruit with a length of less than 15 cm long or 5 branches below the branches and the fruit on the base and branches of the branches.

Third, cultivating weeding and irrigation According to the growth of weeds, weeding and weeding 2-3 times in summer. And insist on the bottom of the canopy 7-10 cm shallow, 25-30 cm deep outside the crown. In the drought from July to August, it is necessary to irrigate drought in time. Any persimmon garden that has not been intercropped should be covered with grass to protect the fattening, keep water, soil and fertilizer, prevent weeds and cold, prevent sunburn, and improve the soil, but pay attention to fire prevention in dry weather.

Fourth, pests and diseases The main pests and diseases are garden spot, corner spot, anthracnose and powdery mildew. It can be sprayed with Baume 0.3-0.5 stone sulphur mixture or 50% thiophanate powder 800-1500 times. A 1:2:100 Bordeaux liquid spray can also be used. The main pests are persimmon caterpillar, chafer, persimmon, blood leaf lobster, persimmon, and moth, which can be sprayed with 40% omethoate 500-1000 times or 50% potassium ammonium phosphate 1000-1500 times. The moth is sprayed with crystals of the enemy worms 600-800 times night. Linyi Fertilizer Network Copyright
Fifth, the topdressing season is the peak season of growth, and the roots and shoots have strong growth potential. The fertilization amount of 1-2 year old saplings was 20 g of pure nitrogen, 10 g of superphosphate and 20 g of potassium chloride. The amount of fertilizer applied per plant in 3-5 years is twice that of 1-2 years old. The adult fruit yield per acre is 4 kg of pure nitrogen (7.8 kg of urea), 4 kg of superphosphate and 4 kg of potassium chloride. And in the periphery of the canopy vertical drip line, 5-10 cm of the young tree; 15-20 cm of the adult fruit tree, excavate an annular groove of 20 cm wide and 20 cm deep. On the cloudy or sunny day before 9 am and after 5 pm, the above three kinds of fertilizers were applied and filled immediately after filling. Linyi Fertilizer Network Copyright

Magnetic Track For Stretch Ceiling
Magnetic rail for stretch ceiling is an innovative mounting system for securing and installing stretched ceilings. This system utilizes magnetic rails and magnetic forces, making installation and adjustment of stretched ceilings very simple and convenient.
This magnetic rail for stretchable ceiling is usually made of aluminum alloy and has high strength and durability. The rails are attached to magnetic strips, while the stretched ceiling is magnetically attached to the strips. This design eliminates traditional fixing methods such as screws or clamps, making the installation process faster and without causing damage to the ceiling surface.
Magnetic System For Flexible Ceiling has several advantages. First, the installation process does not require additional tools or special skills, reducing the time and cost of installation. Second, the Magnetic Track allows the stretched ceiling to be flexibly adjusted and moved to suit different design requirements. In addition, with no visible fixed elements, the ceiling takes on a smoother and more seamless appearance.
Magnetic Strip For Stretched Ceiling suitable for a variety of indoor locations such as residential, commercial space and office buildings. It can be used to decorate suspended ceilings, walls and special design elements, giving a modern, simple and elegant look to the space.
In summary, Magnetic Channel For Elastic Ceiling is an innovative installation system that uses magnetic rails and magnetic forces to hold the stretched ceiling firmly in place. It offers convenient, flexible and aesthetically pleasing solutions for a variety of interior design needs.
