Traditional ginger cultivation is mostly open field cultivation. In general, sowing in the early May of this year in our city, most of them are harvested after frost, and the total growth period is about 170 days, which limits the output of ginger. After experiments with different varieties, densities and sowing dates, we explored and summarized the high-yielding cultivation pattern of ginger in protected areas. Through the earlier sowing period and the delayed harvest, the growth period of ginger was prolonged. The average yield per mu was 4000kg, and the net yield per mu was 6,500 yuan. The specific cultivation techniques are now described as follows: (1) Deep ploughing and site preparation, application of basal fertilizer Ginger roots are underdeveloped, shallow distribution in the soil, poor water-absorbing fertility, neither drought nor resistance, therefore, the choice of terrain It is high and the soil is fertile. In the past three years, no ginger land has been grown for ginger field. Deep plowing about 25cm before winter, late spring thawing fine crushed to two times, sturdy and transparent, virtual virtual reality, so that the earth as a mirror, soil fine like a surface. Combining tillage, Mushi high-quality organic fertilizer 5000kg, ammonium bicarbonate 70kg, potash 30kg, boron 1kg. (2) Precise seed selection and germination Ginger seeds Selection of high yield and disease-resistance Laiwu ginger, with a weight of 50-70g, suitable for 25-30 days before sowing, in a greenhouse in winter or in a room at 20°C, drying 1 -2d, soaked in 200-fold potassium permanganate solution for 10-20 minutes, then air-dried. Pregerminate in a greenhouse or in a greenhouse. Germination temperature is 22-25°C. Generally about 25 days, young shoots can grow to 1-1.5cm. (3) Proper sowing, reasonable close planting on April 1-5, sowing sowing on warm and sunny days, and purely making ginger 4-5 days in advance. Mu planting density 5500-6000, spacing 55-60cm, plant spacing 18-23cm, sowing depth no more than 7cm below ground level, covering the thickness of 2-3cm, requiring watering before planting, water seepage, planting, planting To be neat and uniform, the buds are in one direction. (D) Integrated control of pests and sowing Mushi 3% Phosphate granules 5kg to prevent and control underground pests. The main prevention and control of ginger aphid rotation cropping, strict selection of disease-free ginger, pouring net water application of net fertilizer, found that the diseased plants in a timely manner, and use lime to disinfect the diseased point, the agent can be used Kekexing 800 times plus agricultural streptomycin 1000 Times or 300 times ginger ginger control. After the emergence of yellow ginger ginger borer, cabbage caterpillar, thrips as the main control objects timely spraying, generally use high efficiency and low toxicity and low residual pesticides, such as 24% panacea or insect sweeping light, add cypermethrin or Saiwei Wei, etc. 3 times, 6-8d apart. (v) Strengthen field management Before emergence, generally do not water, no ventilation, proper ventilation or pouring of small water after emergence, keep the shed within the daytime 22 °C -25 °C, night 16 °C -18 °C. Remove the film before the beginning of summer and insert ginger grass or shading with shade nets. Around 20th of October, the shed was tamped and the temperature in the shed was adjusted in time. It was maintained at 22°C-30°C during the day and 15°C-20°C during the night. When the temperature dropped to 8 °C -10 °C, timely harvest in early November. On fertilization, when the height of ginger seedlings is about 30cm, urea is applied to 10kg of urea; before and after the autumn, 10kg of urea and compound fertilizer are applied in combination with the cultivated soil; in the early September, when the ginger seedlings have 6-8 branches, the soil fertility is poor. And the general growth of planting ginger field, Mushi compound fertilizer 20kg and urea 5kg. Pouring water, irrigating water before planting, pouring small water at seedling stage, vigorously pouring water after the beginning of autumn, and often keeping the soil moist. At the same time, the rainy season should pay attention to the timely removal of water in the ditch.
