In the autumn, vegetable planting enters a critical period, so field management is more important. Good autumn vegetable field management is directly related to the effect of increasing production and income.
"Autumn is the period of vigorous growth of ginger, and it is also a critical period for the formation of ginger production. The quality of management during this period will directly affect the yield and quality of ginger. Therefore, it is very important to manage the vigorous growth period of ginger. We must take care of pests and diseases. At the same time of prevention and control, strengthen fertilizer and water management and rational use of plant growth regulators, so as to make ginger stable and high-yield.†On August 18, at the ginger planting base of Minle Village, Dayi Town, Yilong County, agrotechnical experts from the County Agriculture and Rural Bureau and The town’s village agricultural technicians were in the ginger field, explaining the autumn ginger management skills to the villagers on the spot.
Uncover the film in time
We usually cover ginger fields with mulch in order to increase temperature and maintain moisture. After ginger enters the "three-pronged" period, our main tasks are cooling and fertilizer management. Therefore, there is no need for the mulching film to continue to exist. The mulching film actually affects the photosynthesis of ginger leaves, causing ginger buds to grow, which hinders the development of ginger, and even affects the rooting of the root system. At the same time, mulching film is not convenient for us to carry out fertilization, water and agriculture. Therefore, timely peeling of the film can ensure the growth of ginger. The peeling should be done in the afternoon on a cloudy day or weak light intensity.
Cover the border
In autumn, use decomposed garbage fertilizer, pond mud, grass ash soil or other soil and miscellaneous fertilizers to cultivate around the plants, cultivate 2 to 3 kilograms per plant, and then cover the border with dry straw or other weeds. The grass is thick. 5-6 cm, to cover bare ginger, keep the soil moist, and promote the development of ginger.
Cultivating soil and protecting seedlings
In order to prevent the rhizomes from coming out of the ground, the epidermis becomes thicker and the quality deteriorates, the soil should be cultivated, combined with watering and fertilization, for 2 to 3 times of soiling, each time the soil thickness is about 3 cm.
Fertilizer and strong plant
Ginger is a fertilizer-tolerant crop with a long growth period. Ginger enters a vigorous growth period, and the demand for nutrients gradually increases. During this period, topdressing ginger fertilizer should be applied. In summer and autumn, NPK compound fertilizer must be applied to the roots once a month, and each plant shall be applied with 50-60 grams of NPK compound fertilizer every time. At the same time, spray 800 times the vegetable-specific Gaomeishi organic humic acid active liquid fertilizer solution on the leaves every 15-20 days, and spray the leaves with dripping water. You can also use 10-15 kilograms of Guoguang Songer Fertilizer, spray it at a distance of about 10 cm from the plant, and combine with soil to cover it to promote the expansion of ginger rhizomes and provide nutrients for plant growth.
Shade and sunscreen
Jiang likes a cool environment, avoid direct sunlight. In summer and autumn, when the sun is strong, it is necessary to cover a shading net with a light transmittance of only about 50%, or build a shading shed about 1 meter high with branches and leaves to prevent direct sunlight and maintain ventilation , Create a cool environment for the growth of ginger.
Control pests
At present, the occurrence of beet armyworm, cotton bollworm, root-knot nematode and other pests is at its peak, so we must pay attention to prevention and control in advance. In summer and autumn, the roots must be sprinkled with 600 times dixon 1500 times Shennongsu chelated fertilizer mixture once a month, and each plant is sprinkled with about 3 to 5 kg each time to prevent ginger blast.
