Key points of high-yield cultivation techniques for ginger open field
"Winter eat radish and eat ginger in summer, no doctor to prescribe." Ginger warms and dispels cold, appetizing and stomach, and it is also a common seasoning in people's daily life. Its processed products such as ginger powder, ginger oil, ginger sugar, ginger, etc. are even more popular. The main points of high-yield cultivation in open field are as follows: First, choose a good base, prepare enough base fertilizer 1. Select the base. Ginger is warm and shade-tolerant, not resistant to drought, not resistant to waterlogging, not suitable for continuous cropping. It can be rotated with cross-flowered vegetables and legumes. The general forest area planting should be selected at an altitude of 700 meters below sea level, relatively flat, fertile and deep soil for planting; in the hilly plain planting, attention should be paid to selecting sufficient water source, and the soil that can be irrigated is better, and should not be planted in the paddy field. 2. Prepare the base fertilizer. The yield of ginger is higher, ranging from 2,500 to 4,000 kg, and the high is up to 4,500 kg. Therefore, it is necessary to prepare enough base fertilizer. Each mu of broiled pig manure 1500 ~ 2000 kg, plus 40 ~ 50 kg of phosphate fertilizer, can also be used turf, straw, etc. 2000 ~ 2500 kg plus rice compound fertilizer 50 kg and the right amount of human and animal manure piled up after fermentation. Second, select ginger species, destroy ginger buds 1. Choose ginger. There are many kinds of ginger, such as yellow peach ginger, yellow group ginger, yellow silk powder ginger, vegetable scallions ginger, Guangdong sparse meat ginger, Jianghua bamboo ginger, etc., all places should be carefully selected according to the local soil climate and main uses. High-quality ginger should be pure in variety, mature in the previous year, thick and thick, yellow and bright, not shrinking, hard texture, no pests, freezing damage and mechanical damage, and not to be introduced from Jiangyan area. . 2. Ginger buds. First, soak the ginger seeds with 1% quicklime water for 30 minutes or 5% potassium permanganate for 10 minutes, or use "Jiangjingjing" to soak seeds for 0.5 to 1 hour. Dissolve and dry, cover with film boring 6~ After 12 hours, it officially smashed. There are three methods, one is the fire pit method; the second is the farmer fertilizer stacking method; the third is the indoor film method. It should be strictly managed during the bud. The suitable temperature for germination is 22 to 25 °C. It adopts variable temperature and buds, which is 20~30°C in the early stage. After 3~5 days, it stabilizes at 25~28°C and then drops to 20~22°C. Generally, the ginger bud can grow to 0.5-1.2 cm in about 7 days, and the roots can be seen in the bud base. Third, timely seeding, fine management 1. Sowing time: There are clear and early mornings, Lixia is late, and Gu Yu is the same time at the time. Generally, the south can be properly early to Qingming, and the north is suitable for the rain. 2. Seeding rate: 230-250 kg of ginger should be prepared for each acre. After the ginger is budded, the large pieces should be divided into 3 to 5 pieces, each weighing about 70 grams. There is a short bud, and the lateral buds, weak buds and bud bases are blackened, and brown ginger pieces are opened in the open section. . In the southern region, the number of plants per mu is between 4,000 and 5,000, and the density should be appropriately increased in the north, generally between 6000 and 8,000. 3. Planting methods: There are two kinds of ditching and digging. Before planting, first plow 30-40 cm in the whole garden, remove weeds and debris, apply 50-70 kg of lime to improve the soil, level the land, and then excavate the ditch or pit 30 cm deep and 30 cm wide, then plant The ginger is placed horizontally and arranged in a straight line. The plant spacing is 20 to 25 cm? 0 to 70 cm. At the same time, the ginger bud is facing south or southeast, which is beneficial to the ginger and then covers 7 to 10 cm of soil. For moisturizing and grass protection, cover some crops such as semi-rotted straw. 4. Field management: 1 top dressing: For the first time, when the height of the seedling is about 15 cm, a shallow ditch is dug at 15 cm of the ginger seedling, and 20 to 25 kg of urea is applied per acre. The second time, when the height of the seedling is about 30 cm, it is combined with weeding pine and collecting (mother) ginger. Each acre is mixed with 15-20 kg of compound fertilizer, and the soil is 3 to 4 cm after application. The third time depends on the growth of Jiang Miao, generally in the middle of August to September, a small number of batches, 5 to 7 kg of urea per acre, 10 to 15 days, each filling 3 to 4 cm, When each ginger seedling reaches 8 to 10, it should be filled in one time. 2 cultivating and weeding: it is carried out in time after each fertilization or rain. 3 pest control: Ginger is more resistant to pests and diseases, but the occurrence of ginger is more common, causing serious damage. When the diseased plant is found, it should be immediately removed and destroyed. At the same time, the lime in the diseased plant is disinfected and controlled. At the same time, it can be sprayed with 1:1:200 Bordeaux mixture, Dixon 1000 times solution and 50% Dyson ammonium water solution 1000 times, once every 7 days, for 2 to 3 times. Fourth, timely harvest, proper storage Fresh ginger is generally in the middle and late October, after the roots and stems are fully matured, before the first frost comes, with a small amount of moist soil harvest, not drying, there are two direct storage methods, one is the Tibetan method: 5 to 10 days before the harvest of ginger The rice is burned with 50-100 kg of straw in the pot, disinfected at high temperature, cleaned and then put into the pot; second is the film method in the room: the fresh ginger is directly stacked in the house, sealed with a non-toxic plastic film, and the upper part is kept 12 cm. Stomatal ventilation, overlying straw, often check to avoid excessive temperature and humidity and mildew.
