Musk is a commonly used Chinese medicinal material, the whole plant for medicinal purposes, with antipyretic, Qingshu, gas, dampness, stomach, vomiting and other effects, attending cold cold, vomiting, diarrhea, chest tightness, headache, etc. disease. Musk oil is a raw material for the manufacture of various proprietary Chinese medicines. Musk is widely distributed in all parts of the country. It has a long history of cultivation. In recent years, with the development of national medicine and rural economy, the area for planting musk has been expanding. However, pests and diseases that harm musk are more common. Greater impact. In order to protect the development of musk production, the main pest control methods are described below. First, the main disease 1? Corner spot disease: This disease is harmful to the leaves, often occurs in the hot and humid season, began to appear watery lesions, and later gradually expanded to a polygonal brown spot, when severe leaves dry off, resulting in reduced production. Control methods: spraying 1:1.5:120 times Bordeaux mixture at the beginning of onset, spraying once every 7-10 days, spraying 2 or 3 times continuously. 2? Root rot: The disease mostly occurs in the summer rainy season, endangering the roots, or even the whole plant. Diseased plants decayed in the roots and rhizomes, gradually extending to the ground, turning the cortex brown, and eventually withered. Control methods: The diseased plants must be removed in a timely manner and burned in a concentrated manner to prevent the spread of disease. Lime is then disinfected on the diseased points, and the drainage work is done well. 3? Fusarium wilt: The disease occurred from mid-June to early July. The first leaves and leaves of the diseased plant were drooping, blue-green, and finally the roots were rotted. The whole plant withered and severely affected the yield. Control methods: (1) After the harvest of the musk, the diseased plants are removed and burned in order to eliminate the pathogens that pass through the winter. (2) Spraying potassium dihydrogen phosphate in combination with spraying leaves can increase plant resistance to disease. (3) Spray 50% carbendazim 800 to 1000 times or 50% thiophanate 1000 to 1500 times at the beginning of the onset, spray once every 7 days, and spray 2 to 3 times. Second, the main pest 1? Locust: adults and nymphs cluster on the tender shoots of the harm, so that poor plant growth, can not normally grow new shoots new leaves. Aphids can be sprayed with 40% Dimethoate EC 1500-2000 times. 2? Starscream: The worm mainly sucks plant nutrients and affects growth. It can be sprayed with 40% Dimethoate 1500-2000 times. 3. Spodoptera exigua: This worm often occurs from May to October. The larvae eat leaves and affect the photosynthesis. 90% of trichlorfon can be used to spray 1000 times. 4 leaf leafhopper: damage leaves, larvae in young shoots, young leaves spinning silk leaf, hidden in the jujube eating leaves, available 300 to 400 times liquid trichlorfon spray. 5, ground tiger, badger, cricket, etc.: pests bite seedlings, resulting in lack of seedlings, affecting yield, can be made of bait insect traps killing or artificial capture.
Catalysts can induce chemical reactions to change and make chemical reactions faster or slower. Catalysts are also called catalysts in industry. The composition, chemical properties and quality of the catalyst did not change before and after the reaction. It mainly includes solid acid-base catalyst, molecular sieve catalyst, metal catalyst, metal oxide and metal sulfide catalyst, and complex catalyst.
1. Acid-base catalysts: Petroleum refining and petrochemical industry are the largest application fields of catalysts, occupying an important position in the national economy. Acid catalysis plays an important role in petroleum refining and petrochemical industry. Solid acids are further divided into Blans Te Um (B acid) and Lewis acid (L acid). Typical solid base catalysts: MgO, CaO, SrO2, etc; typical solid L acid catalysts: AlCl3, FeCl3, etc.
