Chives cultivation techniques

Chives have strong adaptability, short growing period, insusceptible to pests and diseases, and easy cultivation. Although the yield per mu is only about 1,000 kg, the economic efficiency is higher. The environment requires a fragrant onion and cool climate, with strong cold resistance and heat resistance, suitable temperature for germination of 13-20 degrees Celsius, suitable temperature for the growth of stems and leaves of 18-23 degrees Celsius, suitable temperature for root growth of 14-18 degrees Celsius, and temperature of 28 Above the Celsius growth rate is slow. Due to the shallow root distribution, the water requirement is less than that of onion, but it is not tolerant to drought. The suitable soil moisture is 70%-80%, and the suitable air humidity is 60%-70%. The light conditions require medium strength. Under strong light conditions, the tissues tend to age, the fibers increase, and the quality deteriorates. The loamy soil and the loamy soil land, which are suitable for looseness, fertility, drainage, and watering, are not suitable for planting in sandy land. Requires a balanced supply of nitrogen, phosphorus, potassium, and trace elements, and no single application of nitrogen fertilizer. The planting season is planted in the spring and autumn. The protected area can be planted all year except in the summer; the shade net can be planted in summer. General sowing 60-80 days after harvest, 30 days after transplanting can be gradually harvested. The selection of good varieties used varieties with strong purple scent. At present, the four seasons of small shallots and Fujian chives have performed well. Site preparation fertilization No matter planting seedlings or transplanting plots, fine soil preparation and basal fertilizer should be applied. Apply per acre 3,000 kg of finely ground organic fertilizer or 1,000 kg of chicken manure after pulverization; make 1.5m wide and 8-10m long cabins; summer and low-lying lands should be made higher The ground floor is 15-20 centimeters high and surrounded by drains. Sowing seedlings shall be drilled or sowed in a seeding manner with a spacing of 10 centimeters and a cover soil of 1.5-2 centimeters in thickness; 2-4 kilograms per acre shall be used to prevent the harm of underground pests. Phosphate shall be mixed with sieve fine soil before sowing. On the other hand, it can also be used as a poison bait made from wheat bran mixed with sauteed vegetables. In the evening, it is sprinkled on a seedbed after sowing, and water is poured on the bottom of the plant. Transplanting and planting Planting can be transplanted 40-50 days after sowing, every 8-10 strains of a hole, spacing 12-20 cm, 8-10 cm hole distance, should not be deep shallow, 4-6 cm is appropriate, timely pouring Planting water. It can also be harvested directly after sowing without transplanting. Before and after the emergence of field management and survival after transplanting, the soil should not be arid, and the soil should be well-watered. Control the watering of the seedlings at the 1-3 leaf stage and after the transplanting, and loosen the soil 1-2 times to promote root growth. Water once in 7-10 days. If basal fertilizer is applied less, or harvesting period is too long to top dressing 1-2 times, 300 kg of cooked puffed chicken manure per acre, spread in the rows and timely cultivator, such as opening a hole to better effect. Roots should be soiled 1-2 times in the later period. In summer, the temperature is high and the light is strong. Pest control mainly includes downy mildew, gray mold, purple spot and thrips, leaf miner and other hazards. The methods of agricultural control and physical control should be used as far as possible, and biological or low-toxicity, low-residue pesticides can be used for prevention and treatment when heavier. 68.75% silver faly, 72.2% Prec can be used to control downy mildew; 40% Shijiale can be used to control gray mold; 70% thiophanate methyl and 70% mancozeb can be used to prevent purple spot disease; Fuling; 1% Baolong can be used to control leaf miners.
