Celery is rich in nutrients such as protein, carotene and B vitamins and is popular among people. But pests and diseases cause their quality to decline, affecting its value. The pesticide network Xiaobian collects relevant disease prevention and control skills to share with you:
The celery is threatened by insect pests. The celery early blight is commonly known as spot disease. It usually occurs most in cold and humid environments. It affects the main diseases of high quality and high yield of celery. It should promptly prevent and control the occurrence of diseases and increase production and income.
The celery is infected with insects. It should be noted that the celery pests should be sprayed when the celery seedlings are 3 cm high. Spray once every 7-10 days and spray 2-3 times. In the greenhouse disease period, pesticide manufacturers recommend using 45% chlorothalonil aerosol, 200-250 grams of smoke per mu, or 5% chlorothalonil powder, 1000 grams per acre, convenient for application, and can reduce the shed humidity. Spraying agent can also choose 70% mancozeb wettable powder, 58% toxic manganese-zinc wettable powder, 64% anti-virus WP, 75% chlorothalonil WP, 50% carbendazim wettability Powder, etc.
For the diseased strains, it is necessary to remove them in time to prevent the spread of the bacteria sources remaining in the diseased plants, and to strengthen ventilation and reduce humidity. The Chinese pesticide network recommends spraying the vegetable stalk and stalk spirit in the celery growing season, which can make the celery stems thick and the leaves thick and fresh, thus improving the disease resistance of celery pests.
What materials can I choose for the cabinet handle? Which is good?
At present, plastic, zinc alloy, aluminum alloy, copper, stainless steel, gold and silver are commonly used in the market (these two kinds are basically useless unless the family really has no money to spend)
Plastic handle should be the cheapest. It's rare to know much about it, and it's not recommended to buy it. After all, it takes several years to install a handle, or it's more reliable to buy a metal handle. People of insight are welcome to add it in the comment area.
Zinc alloy is the most common material in handles. More than 80% of the handles you see in the market are made of this material. Why do you ask? Most of the handle manufacturers produce zinc alloy handles. The price of raw materials is medium, not as expensive as copper, which is easier to process. After electroplating, it is very beautiful and has enough weight, So consumers are willing to buy this high-quality and cheap product.
Aluminum alloy handle is popular in recent years. It is cheaper than zinc alloy and has low material density.It include aluminum handles,aluminium door handle,handle aluminium,edging handle aluminium,aluminum profile handle.
Copper handle is the best material, which can be said to be the standard configuration of high-end handle. American, European, light luxury and other cabinets can be selected. It has a large density and heavy weight. It feels very textured, and its appearance and color are also very beautiful. In ancient times, the noble with status was equipped with a copper handle as standard. Of course, the price is also expensive. The raw materials are more than twice that of zinc alloy and aluminum alloy, so the finished products will only sell more expensive!
The style of stainless steel handle is relatively simple. Due to processing and market demand, there are few styles of stainless steel handle, and there is basically only one color, that is, wire drawing texture. We rarely buy it at home, and basically export it abroad.
The handle is bought according to the place of origin. The handle in Shanghai, Shenzhen and Foshan is better than that in Wenzhou. The electroplating process in Guangdong is really good. The price of the handle in these places is more than twice that in Wenzhou!
