The planting method of "Huanghuanxiancao" ginger

Ginger is a perennial herb, known as "reviving immortal grass". It has high edible value and medicinal value, and is widely cultivated in central and southern China. So, what are the planting methods of ginger? Let's get to know it together.

1. Site selection and seed selection

Ginger is very sensitive to water. Ginger is not resistant to drought or waterlogging, and the requirements for water are very strict. When selecting land, try to choose sandy soil with strong permeability, but also be close to the water source, which can facilitate irrigation and drainage. In addition, the selection of ginger should choose healthy, strong tubers and good color ginger, and carefully observe whether the ginger sprouts have vitality and diseases. Ginger sprouts that are withered and sick cannot be selected for planting.

2. Sowing method

When sowing, soak the ginger in the medicine for 10 minutes, then mix it with sand and seal it with plastic film. Generally, you can sow the seeds after five days. This step is to sterilize the seeds and improve the survival rate of the seeds. When sowing, sow seeds at an interval of 30 centimeters for each plant and 40 centimeters for each row, and try to put the germinated side up in such a row, then cover it with a thin layer of soil. finally, cover it with a layer of straw.

3. Fertilizer management

After planting, it is necessary to apply sufficient base fertilizer, which generally requires an average of 3000 kg of organic fertilizer per mu, plus 30 kg of potash fertilizer. The first fertilization is when the ginger seedlings are 225cm high, in rural areas, you can use feces mixed with water, or 20 kg of urea mixed with water for spraying; when autumn is approaching, that is, the beginning of September, the second fertilization is carried out. This fertilization is mainly to make the tubers grow, so the main application of compound fertilizer and potash fertilizer, the amount of fertilizer is 445kg and 30kg respectively. The last fertilization was when the tuber grew slightly to the size of three thumbs, that is, a month after the second fertilization, the type of fertilization was the same as that of the second, but the dosage was halved.

4. Pest control

The main diseases that harm the growth of ginger and affect the yield of ginger are rot and spot disease. Rot usually occurs from summer to early autumn. Plants with disease should be pulled out in time, and the soil next to the plant should be dug up to avoid bacterial infection. Sprinkle a layer of lime, and then fill the ground with soil. The control method of spot disease is to spray 800 times 50% chlorothalonil every 7-10 days. The main pests of ginger are ginger borer and ginger maggots, which are generally controlled by foliar spraying of trichlorfon or phoxim.

5. Harvest

The general harvest season is November and December, when the stems and leaves of ginger have turned yellow and withered, you can start harvesting, but it is best to harvest every two years, ginger should be a little older to be better, so it is not necessary to harvest every year.

The above is the ginger planting method summarized by Xiaobian for you. I hope it can help you.
