Points for attention in planting alpinia officinalis

Alpinia officinarum belongs to Compositae, also known as Guizi ginger. It is a new plant introduced from China and from Europe, and its origin is in North America. The main part that can be used is his underground tuber, which is similar to our common ginger, mainly used to make starch and alcohol, followed by edible, and can be grown as an ornamental plant. Let's take a look at what we need to pay attention to when planting ginger.

1. Soil

Alpinia officinalis has strong adaptability to the planting environment, but it is still necessary to pay attention to the choice of soil quality when choosing soil. The main thing to pay attention to is the acidity and alkalinity of the soil, so the acidity test should be done when selecting the land, and the acidic soil can not be used to grow ginger. Secondly, it is not allowed to grow ginger in saline-alkali areas and marshes, and ginger can be planted in other crop-growing areas and plots that cannot grow crops.

2. Temperature

The planting temperature is also something we need to pay special attention to. Ginger is relatively fine, cool and dry, and its ability to resist cold and drought is good. Generally speaking, when the temperature is about six degrees, it can sprout, and when the temperature rises slightly to about ten degrees, it can sprout. When the temperature is about 15 to 25 degrees, the growth rate of ginger tuber will be faster, so we should accurately grasp its demand for growth temperature in the whole growth process.

3. Sowing seeds

Sowing is mainly the use of tuber propagation, generally using hole sowing or strip sowing. When planting, it is necessary to plan the planting density, row spacing and plant spacing is about 50 cm. When sowing, we should also pay attention to the tuber with the bud point facing up, the depth of sowing is about ten centimeters, and finally cover the soil to cover the seed and wait for emergence.

4. Fertilizer and water

In addition to the base fertilizer, it generally needs two times of topdressing in the process of its growth. The first fertilization is around May, that is, when the ginger seedlings grow to about 15 to 20 centimeters, it is mainly urea to promote the growth of seedlings and make it grow more new branches. The second topdressing was when the ginger began to bud, mainly potash fertilizer to promote the growth of tubers. It is relatively fine and dry, and the watering is generally carried out only at a fixed time, namely, seedling stage, jointing stage, bud stage and tuber stage.

5. Take off the top

Topping is also a very important step in the growth process of alpinia officinarum. When it is time for ginger to bud, we need to remove its buds properly, which can promote the growth of ginger tubers. If the buds of alpinia officinalis are not picked in time, the branches and leaves will grow, the nutrients will be absorbed by the branches and leaves, and the tuber will grow poorly, so in order to improve the yield of alpinia officinalis, this is also worthy of our attention.

The above is the whole content that the editor wants to share with you about the matters needing attention in the cultivation of ginger. In the process of planting ginger, we must pay attention to some more detailed things, so that the yield and quality of planted ginger will be better.
