One is to pay attention to drought-proof, ginger-proof ginger that is not tolerant to drought and not tolerant. It is advisable to keep the soil moist during the growing season. During the high temperature period in summer, it is necessary to water in a timely manner to reduce the temperature. It is better to water in the early and late hours, and pay attention to the timely drainage after the rain.
The second is to pay attention to shading and cooling ginger and hi, not tolerate high temperatures and strong light, shade during summer growth, can be used to cover the shade, or cover the grass on the ground to shade, or intercropping shade and other forms.
The third is to pay attention to the timely cultivation of soil in order to prevent root stems exposed on the ground, thickening of the epidermis, deterioration of quality, soil cultivation, combined with watering and fertilization for 2-3 times earth, each earth about 3 cm thick.
The fourth is to pay attention to pest control and prevention based on comprehensive prevention and control measures. Can be used for crop rotation, germination before sowing ginger, drainage, flood control, chemical control, combined with the timely removal of the diseased plants found in the field, and lime disinfected in the ginger hole. The main insect pests are ginger aphids, ginger aphids, ginger amaranth, etc., and vegetable growers should promptly carry out pest observations and use trichlorfon or phoxim for foliar spray control.
