Turmeric is a plant with great medicinal value, its rhizomes can be directly into the medicine, has the effect of dispelling dampness, clearing heat and detoxification. Studies have shown that up to 120 kinds of ingredients can be extracted from yellow ginger. Because of its unique medicinal value, the price of turmeric in the market is very high. At present, there are also many places in China, especially in Hubei, where large areas of yellow ginger are planted.
1. Soil
Yellow ginger has very special requirements for the growing area, especially the soil. The rhizome of turmeric is relatively thick, so its planting needs to choose a soil layer with a certain ability to retain water and fertilizer. The depth of the soil layer should reach more than 30 cm, the texture of the soil layer is required, not too loose, and the sand content cannot be too high, and there is no problem with the flat slope, and in the process of ploughing the ground, it is necessary to pick up the stones to prevent pressure on the seedlings. In the process of drainage, the distance between the ridges can be placed around 40 to 60 cm, and the drainage ditch should be done well to avoid accumulating water on rainy days and soaking the roots of the yellow ginger.
2. Fertilizer
Farm manure can be selected to increase the fertility of the soil where the turmeric is planted, improve the structure of the soil, and increase the degree of looseness. If you want to plant, about 2,000 kilograms of yellow ginger per acre, it is estimated that 45 kilograms of nitrogen fertilizer, 100 kilograms of phosphorus fertilizer and 60 kilograms of potassium fertilizer are needed. Moreover, in the process of planting, topdressing is also needed, and the amount of topdressing can account for about 30% of the total amount of fertilizer applied. In different stages such as the emergence stage, the initial flowering stage and the full flowering period, a small amount is used separately. Specifically, potassium sulfate and urea can be the mainstay.
3. Sowing
Sowing needs to grasp the timing, in fact, in the spring and autumn can be sown, usually in the middle and lower reaches of the region may be sown in the autumn, if it is autumn sowing, in November, spring sowing, will be at the end of February or early March. The specific amount of sowing can usually be 300 to 350 kilograms per acre. In terms of seed selection, it is necessary to choose some annual or biennial tubers as seeds. Pay attention not to have diseases and insect pests, and the root must be more developed such as turmeric planting, the vitality will be stronger.
4. Set up a frame
Yellow ginger has a relatively strong ability to climb, and it needs to be framed during its growth process in order to increase its photosynthesis. You can use bamboo sticks, or ordinary branches, usually need to start the erection when the buds are 3 to 6 inches, and the preparation pole can be placed 1.2 meters above and below, which requires a price of about 3,000 to 4,000 per acre. When inserting the next root, we must pay attention to the reasonable control distance to prevent stabbing the root of the ginger, so as not to cause the rot of the yellow ginger.
5. Weeding
Turmeric is more afraid of wild grass to compete for nutrients, if there is a presence of wild grass, it is possible to reduce the yield of yellow ginger in a large area, usually it may reach 30%, and at most it may reach 60%, so it is very important for yellow ginger to remove wild grass in time. It can correspond to some herbicides that work well. For example, Henness, Ecuba, Harvest and so on.
6. Cultivate soil
The root system of turmeric ginger is relatively developed, it is drought-tolerant but afraid of rainy days, especially in the rainy season in the south, especially in July to September, when the root is expanded, especially to be excluded. It is very important to cultivate the soil in time to remove the silt in the water and prevent the roots from being soaked by the rain.
7. Control of pests and diseases
In fact, in general, in the newly planted turmeric land, the situation of insect infestation is not too serious, usually in the area of secondary planting. More or less because there are some rotten turmeric in the soil, it will breed bacteria, which will breed pests such as grubs.
8. Harvesting
If it is a year as a planting of ginger, it can be dug, if it is necessary to be used as a processing raw material, it can be dug from 2 to 3 years, in fact, all year round, but usually it is best to dig in November, because at the end of November of each year, the yellow ginger begins to stop growing, which is a better starting to dig, providing the opportunity to plant ginger.
Turmeric should be planted in places where the climate is humid, the sun must be sufficient, the weather should be suitable, and it cannot be rained frequently or in the afternoon. It is better to plant in the sandy land, there is no standing water, you should choose a place where the watering is convenient, and it is best to plough the land before planting twenty centimeters to make the soil looser. Weeding, fertilization, drainage and irrigation are required during growth.
