Green garlic seedlings are called garlic leaves in the hometown of Xiaobian, garlic seedlings are another kind of vegetables, and today Xiaobian wants to talk to you about how to plant green garlic seedlings? In autumn and winter, the outside temperature is generally low. The production of green garlic seedlings takes a long time and the cost is high. However, if you pay attention to the variety selection, pay attention to some advanced production techniques, which can shorten the production cycle. The price is very considerable before and after the Spring Festival, and high economic benefits are achieved. The cultivation techniques of green garlic seedlings in Xinchang County are introduced as follows:
1 plot selection
Garlic should not be used in continuous cropping, and should not be reused with Liliaceae vegetables. It should be planted with flat terrain, good water retention, convenient irrigation and drainage, and loose and fertile soil. It is suitable for grain crops or non-onion garlic vegetables. .
2 variety selection
In order to achieve early maturity and high yield of garlic, it is advisable to choose early-maturing varieties with strong disease resistance, short growth period, wide leaves and soft, high quality and high yield. For example, choose Ershui Zao, Shanghai Chongming Garlic, High Quality White Garlic Zhongnong No.1, Zhongnong No.3 Wait.
3 Fertilization
Green garlic seedlings should be applied to the base fertilizer due to their short growth period and rapid growth. 7d 667m2 before planting, 1500kg of mature farmyard manure, or 1000kg of commercial organic fertilizer, 20kg of urea, 30kg of phosphate fertilizer, 15kg of potassium fertilizer or 50kg of high-quality three-element compound fertilizer, and the land is turned over. Then it is fine and flat, and it is simple and easy to manage. It is 100~120cm wide and 20cm high.
4 sowing
4.1 Seed treatment Select garlic with variety characteristics, fat roundness, garlic cloves neat, no disease spots, no damage, garlic, 667m2 with a seed amount of 200~230kg. Soak the garlic cloves in water for 12 hours before sowing. After soaking, soak seeds with 50% carbendazim WP 200 times for 30 minutes, then soak seeds with 0.3% potassium dihydrogen phosphate for 4~6 hours, remove and drain. At the time of sowing, the garlic cloves were simmered in a solution of 50% phoxim emulsifiable concentrate in 800 times. After the above treatment, it can break the dormancy of garlic, significantly improve the germination rate and stress resistance of garlic cloves, can effectively kill the germs on the garlic species, promote the seedlings and strengthen the seedlings, thereby improving the resistance and resistance of the garlic seedlings.
4.2 Sowing in the autumn in time, according to the climate characteristics and cultivation habits of Xinchang, for the morning market, it can be planted in the middle to late September to early October. 2d watering before sowing, keep the soil moist. Cover the 1.4m wide silver black two-color mulch before planting, punch the hole by 3~5cm, row spacing 8~10cm, insert the garlic stalk into the soil, and sow one garlic clove per hole. It is advisable to have the top bud just exposed to the ground.
5 Field management
Adhere to the basic fertilizer, supplemented by topdressing; organic fertilizer-based, fertilizer-assisted principle, keep the green garlic seedlings fresh, spicy and delicious flavor.
5.1 Watering at the right time Watering according to soil moisture and plant growth. In the germination period, the soil is kept moist to promote the germination of the garlic, and the seedling water is poured once after the emergence. When the seedling grows to 7~10cm, the water is poured again, and then the soil is watered for 1~2 times.
5.2 After topdressing the garlic seedlings, the first top dressing is carried out. The quick-acting fertilizer is suitable, and the nitrogen fertilizer is the main one. It can be combined with watering, and the 667m2 is applied with 7~10kg ammonium sulfate or 5~7kg urea. When the seedling height is 7~10cm, the second top dressing is carried out, and 10kg of ammonium sulfate or 7~10kg of urea is applied in combination with watering 667m2. When the seedling height is 14~16cm, the third top dressing is carried out, and 7~10kg of urea or 10kg of ammonium sulfate is applied in combination with watering 667m2. In the late growth stage of garlic seedlings, 0.3% potassium dihydrogen phosphate aqueous solution or foliar fertilizer was sprayed every 10 days to prevent premature senescence of the plants. Fertilization was stopped about 15 days before harvest.
5.3 Timely construction of small greenhouses During the autumn and winter production of green garlic seedlings, the temperature will continue to decline. In the later stage of growth, it is necessary to build a small arch shed in time, cover the film, increase the temperature to ensure the normal growth of garlic, and ensure the product is on the market.
6 pest control
In accordance with the principle of prevention and comprehensive prevention and control, priority is given to agricultural prevention and control, physical control, rational use of chemical control, and the prohibition of using high-toxic and high-residue pesticides prohibited by the State to ensure pollution-free standards.
6.1 Agricultural control Improve the resistance by selecting resistant varieties or detoxified garlic seeds, and soaking seeds for 2~3 days before sowing; implement rotation with food crops or non-onion garlic crops, deep turn sun drying, timely sowing, and reasonable close planting. Increase the application of decomposed organic fertilizer, strengthen cultivation management, clean up weeds and sick bodies around the field, and reduce the number of pests and diseases.
6.2 Physical control By setting 1 ç› frequency vibrating insecticidal lamp every 2~3hm2, 667m2 hanging 30~40 yellow plate, 667m2 setting sexual attractant 1 set or using sweet and sour liquid to trap flies pests.
6.3 Pest Control Chemical pests mainly include root lice, leafminer, onion, aphid and so on. Garlic 3~4 leaf stage, 667m2 is controlled by 1.8% harmful emulsifiable concentrate, 1.8% edetatin emulsifiable concentrate, pyrethroid pesticide 10~15mL or 1% chlorfenapyr granules; the root mites can be used at 800,000 IU/ mL of Bacillus thuringiensis wettable powder 5~6kg, 1.5% natural pyrethrin water emulsion 1200 times liquid, 1.8% avermectin emulsifiable oil 1000 times liquid, 80% trichlorfon soluble powder 1000 times liquid or 50% phoxim emulsifiable oil 800 Double liquid irrigation and control.
6.5 Disease chemical control diseases mainly include leaf blight, purple spot, rust and viral diseases. At the beginning of the onset of leaf blight, 75% chlorothalonil WP 600 times solution, 2.5% flavonoids suspension 1200 times solution or 41.5% prochloraz emulsifiable concentrate 1500 times solution can be used for spraying every 7~10 days. Prevention and treatment 2~3 times; 70% mancozeb 1000 times solution + 15% triazolyl 2000 times solution, 20% triazolone EC 2000 times solution, 14% ammonia copper solution 300~500 in the early stage of purple spot disease Double liquid or 10% difenoconazole water dispersible granules 1000 times liquid spray control, pay attention to alternate medication; 30% diphenyl ether bixazole · propiconazole EC 2000 times solution, 12.5% ​​diniconazole available at the beginning of rust Wet powder 2200 times liquid or 25% enemy de-emulsion 3000 times liquid spray control; 1.5% phytopathogenic 1000 times solution, 20% virus A500 times solution or 31% morpholinium ribavirin in the early stage of viral disease Soluble powder 800 times solution + recycled lotion 500 times liquid spray, spray once every 5~7 days, even spray 2~3 times.
7 Harvest at the right time
Garlic is suitable for harvesting fresh and tender garlic seedlings in the case of suitable temperature and sufficient fertilizer and water conditions. When the garlic seedlings grow to a height of 30~50cm or more, they can be selected in batches according to market conditions, or they can be harvested in one-time harvest. The output of 667m2 is as high as 2000~2500kg. In order to prolong the supply period, increase production and income, the crops should be harvested in batches, and the roots and old leaves should be removed during harvesting, and the soil and debris should be washed and listed.
