The latest course of cultivation techniques and methods of alpinia officinalis

Alpinia officinarum, also known as alpinia officinarum, is a perennial herb of Zingiberaceae, which is mainly distributed in southwest China. The leaves of alpinia officinalis are luxuriant, bright and colorful, and have high ornamental value. And alpinia officinalis is also a kind of traditional Chinese medicine, which has the effects of relieving cold and relieving pain, pungent powder and warming. Generally can be used for the treatment of stomach cold, abdominal pain and other problems, its efficacy is strong. So how to grow good ginger? The following is the editor to introduce the cultivation techniques of liangjiang.

1. Land selection and preparation

Liangjiang is suitable to grow in the soil with thick soil layer, sufficient fertility, soft and permeable soil and normal drainage and irrigation, in the position of sandy soil. After selecting the site, the weeds in the soil and the residues of previous crops should be removed in the winter of the first year of planting, and the plant ash should be burned to be used as fertilizer. Then the soil preparation will be carried out and the soil will be crushed and leveled before the spring of the following year. The depth of deep turning should be maintained at about 30 centimeters, because the growth ability of good ginger is relatively strong, so there is no need to make beds during soil preparation, generally mainly by reclamation. It can be interplanted with pineapple, citronella and other crops in the field.

2. Rhizome propagation

The propagation method of alpinia officinalis is generally based on rhizome propagation. When we harvest alpinia officinalis, we should choose about 7 concentrated buds that grow in two years as the rhizome. Strong buds should be fat enough to ensure that there are no diseases and insect pests, and then cut the buds into small segments of about 14 centimeters, each retaining 3 nodes. It is usually done in the spring and autumn, and then in the soil that has been prepared before, the planting density is controlled and the planting holes are dug. Put 1-2 segments in each planting hole. Then cover the fine soil and compact it, pour enough water to fix the root, and promote the rooting and sprouting of the rhizome.

3. Timely transplanting

If sowing in spring, it is generally appropriate to transplant before and after Ching Ming Festival, in the soil prepared, apply sufficient base fertilizer, pay attention to the amount, mainly to 2600-2800 kg / mu, to improve soil fertility. Then we should also pay attention to control the row spacing of plants, generally dominated by hole species. The depth of the planting hole is controlled at about 18 cm and the width is about 28 cm. Then put each planting hole in the rooting rhizome into a section and fill the soil at the same time. After transplanting, it is necessary to cover fine soil, water, do a good job of weeding, and improve the survival rate of transplanting.

4. Field management

When the seedlings grow to about 5 cm, it is necessary to do a good job in the work of seedlings, follow the principle of staying strong and removing weakness, and control the distance between seedlings at about 5 cm. And in the seedling stage should pay attention to do a good job of weeding, not less than twice, and after the closure of the line should be appropriate weeding every quarter. Then according to the weather and soil moisture to do a good job of watering, keep the soil moist, and promote the tillering and rhizome growth of alpinia officinalis. In addition, we should pay attention to topdressing in time to meet the nutrients needed in the growth of good ginger, and finally intercropping crops with low nutritional requirements in the field to improve land utilization.

The above is a brief introduction to the cultivation techniques of alpinia officinarum. The growth ability of alpinia officinalis is relatively strong, but we need to do a good job in field management to enhance its resistance and ensure its healthy growth.
