I. Land Selection and Preparation
Ginger grows in a warm, humid and sunny environment. When selecting land, loam or sandy loam with deep soil layer, good drainage and rich organic matter should be selected. Before planting, the land should be deeply ploughed, raked and leveled to create good soil conditions for the growth of ginger.
Second, seed selection and treatment
Selecting high-quality, high-yield and disease-resistant ginger varieties is the key to ensure ginger yield. Before sowing, seeds should be treated, such as drying, soaking and dressing, so as to improve the germination rate and disease resistance of seeds. At the same time, the germination of seeds can be accelerated, which is beneficial to the growth of ginger.
Third, sowing and planting
Ginger is generally sown by drilling or hole sowing, and the sowing depth is 2-3 times of the seed diameter. After sowing, cover with a thin layer of soil and gently compact it to keep the soil moist. When the seedlings grow 2-3 true leaves, carry out thinning and planting, keep the plant spacing appropriate, and ensure the full growth of ginger plants.
Fourth, fertilization and watering
Ginger has a long growth period and needs a large amount of fertilizer. When applying fertilizer, we should follow the principle of "sufficient base fertilizer and diligent topdressing" and rationally apply nitrogen, phosphorus and potassium fertilizer according to different stages of ginger growth. At the same time, keep the soil moist to meet the water demand of ginger growth. In case of drought, water it in time; In rainy days, do a good job of drainage to prevent diseases caused by accumulated water.
Five, pest control
Ginger is vulnerable to pests and diseases during its growth. In order to effectively control diseases and insect pests, we should first choose varieties with strong disease resistance, and then strengthen field management to improve the disease resistance of plants. Once signs of pests and diseases are found, biological control and chemical control measures should be taken in time for comprehensive control.
