1 plot selection
The garlic should not be used for continuous cropping, and should not be replanted with the Liliaceae vegetables. The plots should be flat and well-watered, with convenient drainage and drainage, and loose and fertile land. It is advisable to use food crops or non-onion and garlic vegetables as the land for the former crop. .
2 species selection
In order to achieve the early maturity and high yield of garlic sprouts, early-maturing varieties with strong resistance to disease, short growth period, short leaves and soft, high quality and good yield should be selected. For example, Dishuizao, Shanghai Chongming Garlic, and high-quality white garlic Zhongnong No. 1 and Zhongnong No. 3 Wait.
3 Soil fertilization
Because of the short growth period and the rapid growth of green garlic seedlings, base fertilizer should be applied. Before sowing, 7d667m2 will be applied to 1500kg of farmyard manure, or 1000kg of organic fertilizer, 20kg of urea, 30kg of phosphate fertilizer, 15kg of potassium fertilizer or 50kg of high-quality three-element compound fertilizer. Then the sorghum is leveled and cultivated for sorghum cultivation. It is simple and easy to manage. It is 100-120cm wide and 20cm high.
4 sowing
4.1. Seed treatment Featured garlic varieties with variety characteristics, large roundness, neat garlic, no spots, and no damage, 667m2 seed amount 200~230kg. Before sowing, clove should be soaked in water for 12 hours. After removing, soak 50% Carbendazim WP 200 times for 30 minutes, then soak in 0.3% KH2PO4 for 4~6 hours, and remove the drain. At the time of sowing, the garlic clove was sown in 800 times of 50% phoxim EC. After the above treatment, the dormancy of the garlic seeds can be broken, and the germination rate and the stress resistance of the garlic seeds can be significantly improved, the bacteria on the garlic seeds can be effectively killed, the miao seedlings can be promoted, and the disease resistance and resistance of the garlic seedlings can be improved.
4.2 timely planting sowing in autumn, according to Xinchang region climate characteristics and cultivation habits, to mention the morning market, can be sown in late September to early October. Water 2 days before sowing to keep the soil moist. Before planting, cover 1.4m wide silver and black two-color mulch, drill 3~5cm spacing, 8~10cm spacing, insert garlic into soil, and soak 1 clove of garlic in each hole. The top buds have just exposed the ground.
5 Field Management
Adhere to basal-based, supplemented by top dressing; organic fertilizer-based, chemical fertilizer supplemented by the principle of keeping green sprouts fresh, spicy and delicious flavor characteristics.
5.1 timely watering According to soil moisture and plant growth timely watering. During the germination stage, the soil was kept moist to promote the germination of garlic seeds. After emergence, the seedling water was poured as often as possible. When the seedling grows to 7~10cm, it is poured with water once more, and then the soil is watered 1~2 times.
5.2 Dressing Garlic Qimiao after the first top dressing, fast-appropriate fertilizer is appropriate, and the main nitrogen fertilizer, combined with water, 667m2 topdressing ammonium sulfate 7 ~ 10kg or urea 5 ~ 7kg. When the seedling height is 7~10cm, the second topdressing is performed, and combined with watering of 667m2, topdressing with ammonium sulfate 10kg or urea 7~10kg. When the seedling height is 14~16cm, the 3rd topdressing is performed, and the combination of watering 667m2 topdressing urea 7~10kg or ammonium sulfate 10kg. In the late growth stage of garlic, spray 0.3% potassium dihydrogen phosphate solution or foliar fertilizer every 10 days to prevent premature aging. About 15 days before harvest, stop fertilizing.
5.3 timely construction of greenhouses in autumn and winter production of garlic bulbs continue to decline during the period, to the late growth period, depending on the circumstances, the need to promptly build a small arch, cover the film, increase the temperature to ensure the normal growth of garlic, to ensure that the market.
6 Pest control
According to the principle of prevention and comprehensive prevention and control, priority should be given to agricultural control, physical control, rational use of chemical control, prohibition of use of highly toxic and high-residue pesticides prohibited by the State, and ensuring pollution-free standards.
6.1 Agricultural control Through the selection of disease-resistant varieties or detoxification garlic seeds, sowing 2~3d before sowing and other ways to improve resistance; implement crop rotation with food crops or non-onion and garlic crops, deep-turning sunburn, appropriate sowing, and reasonable close planting. Increase the use of decomposed organic fertilizers, strengthen the cultivation and management, clean up the weeds and diseased areas around the field, and reduce the number of pests and diseases.
6.2 Physical prevention and control By setting 1 ç› frequency vibration insecticidal lamp every 2~3hm2, 667m2 hanging 30~40 yellow plates, 1 set of 667m2 sexual attractant, or using sweet and sour liquid to induce fly pests.
6.3 Insect Pests Chemical pests mainly include root plagues, spotted lilies, onion thrips, and locusts. During the 3 to 4 leaf stage of garlic, 667m2 was selected to be 1.8% harmful to chlorinated EC, 1.8% of edestin EC, and 10 to 15 mL of pyrethroid pesticides or 1% bifenthiazide granules; mL Bacillus thuringiensis WP 5~6kg, 1.5% natural pyrethrin 1200 times liquid, 1.8% avermectin EC 1000 times, 80% trichlorfon soluble powder 1000 times or 50% phoxim EC 800 Double liquid irrigation and control.
6.5 Diseases Chemical control diseases mainly include leaf blight, purple spot, rust, and viral diseases. In the early stage of the onset of leaf blight, 75% chlorothalonil WP can be used as 600 times solution, 2.5% fluocinilone suspension can be used as 1200 times solution, or 41.5% prochloraz can be used as a 1500 times solution, and sprayed once every 7~10 days. Control 2 or 3 times; Early stage of purple spot disease can be 70% mancozeb 1000 times liquid +15% azoxanthene 2000 times, 20% triadimefon EC 2000 times, 14% urea copper water agent 300~500 Diluent or 10% difenoconazole water dispersible granules 1000 times spray control, pay attention to alternate medication; rust can be used at the beginning of the disease can be 30% difenoconazole cyproconazole EC 2000 times, 12.5% ​​diniconazole wettability Powder 2200 times or 25% of the enemy's de-emulsifiable oil 3000 times spray control; virus disease at the beginning of the disease with 1.5% plant disease Ling 1000 times, 20% virus A500 times or 31% morpholinium ribavirin soluble powder 800 times liquid + rejuvenation 500 times liquid spray, spray 5 to 7 days, even spray 2 or 3 times.
7 timely harvest
With suitable temperatures and adequate fertilizer and water conditions, garlic can be harvested after being sown for about 70 days. When the garlic grows to 30~50cm in height, it can be collected in batches according to the market conditions, and it can also be harvested in one batch at a time. The output of 667m2 is as high as 2000~2500kg. In order to extend the supply period and increase production and income, the harvested plants should be harvested in batches, and fibrous roots and old leaves should be removed at the time of harvesting.

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.
