Water and fertilizer management after turning green garlic, garlic is the key to high yield. The weather gets warmer, water and fertilizer uptake increases after reviving, especially in pregnant and garlic sprouts enlargement of the period is the peak of garlic need water and fertilizer, so the entire growing period of garlic according to soil fertility Offers and growth of the seedlings, time pouring Water dressing, with particular focus on pouring good "Sanshui" Shi "three fat." 1. reviving water pouring good, good turn green fertilizer applied. To the vernal equinox, garlic fat trees start turning green, since early spring to low temperature, preferably at noon pouring good water turning green, the purpose and promote seedling early onset, with watering NPK fertilizer per acre punch 15 to 25 kg, or potassium topdressing 15 kg, after appropriate water control, and promote root development and garlic sprouts, garlic differentiation. 2. reminder sprouts pouring enough water, re-applied fertilizer reminder sprouts. In early April, end of March are flower buds, bud scales rapid differentiation period, and gradually into the garlic sprouts, garlic grow hand of leaf area reached maximum, garlic sprouts grow rapidly, fertilizer and water management this period directly affects the garlic sprouts, garlic production. And then need more water, watering must be timely in order to meet their needs grow, so the combination of water 25 kg per acre compound fertilizer Chong, 15 days and then washed NPK fertilizer per acre 25 kg or urea, phosphorus and nitrate Each 15 kg of potassium fertilizer. Usually 7 to 10 days pouring of water, garlic bolting, water once every two Debris facilities available nitrogen once every 5 to 7 days, combined with foliar spraying fill spray some sulfur, garlic also more demand for sulfur more. 3. pouring enough water swelling, swollen skillfully fertilizer. Postharvest garlic sprouts is swollen peak, protect sprouts leaves and roots during harvest. Then with garlic swelling weight gain based, timely watering after harvest sprouts, garlic leaves to prevent premature aging and prolong blade green time, and to promote the transfer of nutrients to the bulb to increase the accumulation of material-based. Therefore, the available nitrogen fertilizer to mainly with phosphorus, potassium supplement, urea or potassium per acre fertilizer punch 15 to 20 kg. Keep the soil moist, in order to meet the water needs of the late garlic, about a week before harvest watering stop. Suitable sowing from October 1 - December 2. Sowing principle is: cool area suitable for early sowing, warm area suitable delayed. Rational close planting to harvest garlic and garlic-based, general spacing 20cm, 15cm spacing planting density of 2 .-- 26,000 / acre, acre seeding rate of 150 kg, seeding promote shallow sowing. According to test results showed that shallow sowing appropriate, can improve garlic, increase production, so mulch after planting depth should be controlled by 2.5cm. Comparison of heavy clay soil mulch should be shallow. Fourth, timely irrigation water to fertilizer to promote seedling fertilizer: timely irrigation: Garlic shallow root distribution, not drought, nor water logging, should be based on soil moisture and plant growth conditions, timely irrigation. Rational fertilization: Because garlic growing season length, amount of fertilizer needed, the general quality Mushi base fertilizer amount, in particular, even as the plots, but also to add organic fertilizer. Inorganic fertilizer application, N, P, K ratio: 40-60 kg of urea, superphosphate 30-50 kg, 15-30 kg of potassium sulfate. Basal and SSP as base once applied, urea and potassium sulfate points back of the mother (4-6 leaves) and Peng period (9-10 leaves) applied twice, retired mother of fertilizer accounts for 60 percent, accounting for 40 of Peng %. Weeds through 2 --- 3 days after sowing watering, grasses grass one-time foliage treatment, per acre with 40% garlic grass net 110 ml or 20% of chlortoluron 300 g / acre watered spray . Disposable herbicidal effect over 90% of garlic production is safe and effective, then mulching. Fifth, timely harvest: 1, garlic harvest. Garlic can be harvested when the leaf sheath extending garlic inflorescence bracts 13-16cm, election after harvest dew dry sunny or cloudy afternoon were. 2, received garlic. Garlic general requirements "received nine yellow ten" too early harvest, tender garlic, water weight, after drying garlic skin wrinkling, too late receipt, garlic skin discoloration susceptible to cracking, poor commodity, product quality. Garlic and garlic alone points should be harvested in batches. Lies in the garlic harvested after 20-30 days, when yellow leaves can be harvested, to harvest its mud, cut roots, cut to avoid mechanical damage.
