The sowing time of autumn vegetables is at the flood season. The climate characteristics of high temperature and rainy weather determine the occurrence of pests and diseases, and the characteristics of the occurrence of pests and diseases should be promptly mastered. Diseases and pests have characteristics The main diseases are downy mildew, soft rot, and viral diseases. The downy mildew disease is generally dominated by adult plants, with the most obvious symptoms, which mainly damage the leaves. At the beginning of the disease, light green spots appear on the leaves. The veins are limited by the veins, and when the humidity is high, the back of the lesions grows mildew. Layers, when the condition is severe, can connect the lesions to cause dead leaves. Aspergillus pygaea prefers warm and high humidity conditions. Therefore, even when there is a large temperature difference between cloudy days and nights, long dew condensation time or poor drainage, poor ventilation results in heavy weight. Soft rot is mostly bacterial, and the common feature is that the disease department is sticky, soft and rot, accompanied by odor. In recent years, the occurrence of soft rot in Chinese cabbage has been severe, with a general reduction of 10-20% in production and more than 50% in severe plots. Soft rot occurs mainly through wound invasion, such as insect damage, mechanical damage, natural rifts, etc., so to avoid the wound can reduce soft rot. The main symptoms of viral diseases are mosaics, shrinkage, and deformity. They are mainly transmitted by locusts, whitefly, and planthoppers, and the conditions of high temperature and dryness are conducive to the propagation of locust infestations. The occurrence of viral diseases is heavy. Once the virus disease occurs, prevention and control are more difficult, and cutting off the transmission of the virus is a key measure to prevent viral diseases. The main insect pests are Helicoverpa armigera, Spodoptera litura, Spodoptera litura, Pieris rapae, Plutella xylostella, Aphids, Bemisia tabaci, Liriomyza spp., Smilax glabra, Aphids, Leafhoppers, snails, wild grasshoppers, yellow striped beetles, and tigers. , Golden needles, cockroaches, cockroaches and so on. Cabbage seedling stage is a period of concentrated occurrence of many kinds of pests, often causing seedlings to break ridges and destroy seed. Grasping seedling control is the key. Do not hesitate to treat medication Before or at the onset of downy mildew, 69% of dimethomorph MnZn, 72% of cymoxanil, 58% of metalaxyl MnZn WP, 600-800 times, or 72.2% of Preclosure, 400 times of spray . Soft rot usually begins at the seedling stage and is sprayed with 72% streptomycin-soluble powder 3000 times every 7 days for 2-3 times. Virus diseases enhance the control of insects such as acarids and whitefly, and can be sprayed with 20% acetamiprid soluble liquid or 25% thiamethoxam water dispersible granules 3000 times, while adding 0.5% amino oligosaccharide water 500 Double liquid passivation virus development. Helicoverpa armigera, Spodoptera exigua, Plutella xylostella, Pieris brassicae (BT cream) 1,000 times or 1% Emamectin benzoate emulsifiable concentrate or 2.5% lambda-cyhalothrin 2500-fold spray. After emergence, the soil maggots, earthworms and earthworms were mixed with 50% phoxim or 48% chlorpyrifos and wheat bran into 1% baits. They were sprinkled in vegetable fields in the evening, or sprayed 1,000 times with pyrethrin and phoxim. Snails, wild medlar 6% Tetraacetaldehyde granules (Medd) Mu 250-500 g evenly applied to the crop rhizosphere soil trapping, climbing to the leaves of the available spray type 25 grams of water 15 kg spray . Yellow strips of armor are treated with 1000-fold of 50% phoxim EC or 10% of cypermethrin EC 2 000-fold to prevent larvae and cure other underground pests; use the above organic phosphorus or pyrethroid pesticides or 10% of chlorfenapyr (divided ) Suspending agent 1500 times or 5% fluorinated chloramphenicol 2000 times spray control of adult worms. Collagen is the most abundant protein in mammals, accounting for 25% to 30% of the total protein. It is widely present in all tissues from the body surface of lower vertebrates to mammalian bodies. Collagen monomers are long cylindrical proteins with a length of about 280 nm and a diameter of 1.4–1.5 nm. It consists of 3 polypeptide chains that are supercoiled around each other.
