First of all, we should choose areas with excellent environment. The soil must be fertile and loose, and the soil layer is deep. Select excellent varieties with high yield, high quality, good commodity and strong stress resistance. The main variety in South China is generally white silk ginger. When picking and digging ginger seeds in the first year, choose strong ginger pieces without pests and diseases to collect and store, and choose ones with good color, short internodes and fat before sowing. Generally, planting in the open field in the south is sown in the first half of April, and it should be sown early during this period.

First, southern ginger planting technology and management

1, planting mode

(1) First, choose areas with excellent environment for planting, mainly sandy loam, with fertile and loose soil and deep soil layer. Generally, mountainous towns and villages are very suitable for planting ginger, because these places are rich in soil resources.

(2) Select excellent varieties with high yield, high quality, good commodity and strong stress resistance. The main cultivated variety in southern China is generally white silk ginger, with short plants, lanceolate leaves and green color. The rhizome is yellow and white, fat, the ginger stem is fat, spicy and soft, and the quality is good. The surface of the rhizome is smooth, the scales at the tender buds are purplish red and the water content is high.

(3) When picking ginger seeds in the first year, you must choose ginger pieces that are robust and free from pests and diseases for harvesting and storage. Before sowing, you must choose ginger pieces with good color, short and fat internodes, no pests and diseases, and no decay, and then soak them in plant ash solution or 50% carbendazim solution for 500-600 times 15-20 minutes to disinfect the ginger.

(4) In the south, the time of artificial planting in the open field is generally in the first half of April, and it is best to broadcast it early during this period. When the temperature and ground temperature are stable at 15? C, you can choose to sow in sunny days, and keep the plant spacing at 30-35cm. Discharge the sprouted ginger pieces into the planting ditch with the ginger buds facing upwards, and then cover them with fine soil for 4-5cm.

2. Management methods

(1) After sowing, intertillage weeding should be carried out in time, generally 2-3 times. Deep intertillage and thin soil cultivation in the early stage and shallow intertillage and thick soil cultivation in the later stage. You can also use 75 kg of 60% butachlor mixed with 50 kg of water or 50 kg of 25% herbicide diethyl ether mixed with 50 kg of water to weed before emergence.

(2) In early May, we can start to set up a shed to shade the Jiang Miao, build a flat frame with a height of about 1m, and then put a sunshade net on it to facilitate plant growth. Generally, the shade shed should be removed in late August to increase the light and increase the yield.

(3) When the height of ginger seedlings is 20-30cm, topdressing is carried out for the 65438th time, and second fertilization is carried out for the third branch. Every 667m2, 500-600kg of decomposed manure is watered with 3000-3500 times of water, or 20-25kg of 45% potassium sulfate compound fertilizer is applied in intertillage. Generally, when the weather turns cold in late August, Zhuang Jiang fertilizer can be applied, and generally 25-30kg of 45% potassium sulfate compound fertilizer can be applied.

Second, a new formula for soaking and disinfecting ginger seeds

1. Before ginger is crushed, the seeds can be soaked in 1: 1: 100 bordeaux solution for about 20 minutes, or they can be soaked in 500ml/L neophytomycin, clarithromycin and streptomycin sulfate for about 48 hours, or 800% copper oxychloride.

2. After breaking the ginger, dip some fresh and clean plant ash into the broken mouth to seal the wound, and then sow. Before sowing, be sure to soak the seeds in 1: 100 formalin for about 0 minutes, then take them out, filter them and seal them in plastic film bags for 6 hours.

3. When planting, ginger should germinate. Ginger stove germination method and kang germination method can be used. First, put 20-26 ginger seeds? It takes about 20 days to accelerate germination in the environment around C. In this process, we must adjust the temperature not too high, otherwise it will easily burn the seeds. Accelerate germination for about half a month, and continue to observe the germination rate of ginger seed buds. Ginger seeds with buds about 1-2cm long can be taken out in about half a month.
