Farmers grow ginger: pay attention to these items

Strict selection of land to avoid continuous cropping: select sandy loam, loam and clay loam with fertile soil, deep soil layer, good air permeability, rich organic matter, strong water and fertility conservation, which requires slightly higher topography, convenient drainage and irrigation, and is not easy to accumulate water.

Ginger is not suitable for continuous cropping, but should be rotated for 3-4 years with rice, cruciferous and legume crops.

Select ginger species to promote early hair: choose ginger with fat and plump pieces, bright skin color, fresh meat, hard texture, 2 strong buds with 1 Mel, weight 50 Mel 75 grams, disease-free old ginger.

Soak the ginger with 50% carbendazim 500 times solution before sowing. After disinfecting the ginger, the ginger can be stacked when the surface of the ginger block shines for 3 days, covered with straw to keep it moist, and the temperature should be controlled at 20-25 ℃. When the ginger bud grows to 1 cm, it can be sown.

Ginger stem vine management:

1. Erection: when the stem of Dioscorea zingiberensis is as long as 30cm after emergence, it should be set up as soon as possible, and the bamboo and wooden sticks which are about 1.5-1.8m long and thick as fingers are inserted into the outer edge of the trench and hole, one at a time, tied into a bundle at the upper end of every four, to form a "x" type, to facilitate weeding and topdressing, and to lead the stem vine to the shelf at a height of 1.2m-1.4m from the ground, so that it can grow along the shelf, and pay attention to control the stem vine growth height.

2, topping: when the main stem vine grows to a certain height (1.4m-1.5m) to reach the top of the frame or the lateral branch reaches 20-30cm, the main stem and lateral branches should be topped in time to control vegetative growth; when budding and flowering, the flower buds should be removed in time, generally every 10 days, in order to reduce nutrient consumption and promote nutrient transfer and accumulation to underground rhizomes.

Do a good job in the control of diseases and insect pests: the main diseases are rot and spot disease. The rot disease usually begins in July, and the peak period is from August to September. It is found that the diseased plants are pulled out in time, the diseased soil is dug up, lime is applied in the disease hole, and the soil is buried with clean aseptic soil.

50% chlorothalonil 800 times solution was sprayed at the initial stage of the onset of spot disease, once every 7 to 10 days. The main pests are ginger borer and ginger maggot, which are controlled by foliar spraying with trichlorfon or phoxim.
