Planting method and time of alpinia officinalis

The planting method of sand ginger: select dry land, paddy field, etc., the soil should be fertile and loose, good drainage and irrigation, 15 days before planting, the soil should be ploughed and sterilized, and then the seeds with disease-free, uniform size and hard texture should be selected. heap seeds after one week of sun exposure, disinfect the seeds with formalin before sowing, replenish seedlings in time after emergence, timely drainage, weeding and control of diseases and insect pests in the later stage. Sand ginger planting time: every year around the Spring Equinox or Qingming Festival.

First, planting time

Sand ginger is generally sown before and after the Spring Equinox or Qingming Festival, it is not suitable to sow too late, otherwise the high temperature will affect the seed germination rate.

II. Land selection and preparation

1. First of all, dry land, paddy field and slope land should be selected for planting sand ginger. The soil requires good drainage and irrigation conditions, fertile and loose soil, warm climate, short sunshine time, abundant Rain Water and so on.

2. After the planting site is selected, the soil is turned over for the winter, and can be planted after the soil layer is weathered. About 15 days before planting, the soil needs to be ploughed, then sterilized, carbendazim powder and 50% benzoylammonium can be used, and about 400 kg of water can be mixed. After 2-3 days, it is evenly sprayed in the soil and ploughed at the same time.

Third, select the species of sand ginger

1. Fully mature sand ginger, such as thin skin, no disease, uniform size and hard texture, should be selected as seeds before planting.

2. Choose a sunny place to expose the harvested sand ginger seeds for about a week, then store them in a well-ventilated place and pile them with a layer of lime on the ground, then pile them into the ginger seed pile. The stacking height should not exceed 17cm or so. In order to maintain ventilation, the door had better be opened from time to time.

3. Before sowing, you also need to use formalin to disinfect the seeds for about 20 minutes, and then dry them to plant.

IV. Rational planting

1. In order to increase the yield of sand ginger, close planting should be carried out reasonably, and it can be planted according to about 20,000 plants per mu.

2. When planting, you can plant according to the row spacing 16.5cm or so, the plant spacing 20cm or so, the depth of each plant is about 10cm, each hole can plant about 2-3 sand ginger, the planting amount per mu is about 125150kg, it can be arranged according to the product glyph, the bud eyes are facing both sides, and then cover the fine soil.

V. rational fertilization

1. When planting sand ginger, sufficient base fertilizer must be applied, together with an appropriate amount of compound fertilizer or mature farm manure, which can be applied by ditch application or mixed application.

2. When sand ginger emerges, it should be fertilized outside the root and water, and a small amount of fertilizer should be applied, which is more conducive to the normal growth of sand ginger. After mid-October, the amount of fertilizer can be increased appropriately, about 7.5kg per mu, after the Autumn Equinox. Fertilizer can be applied every other week, spraying 2-3 times, which is beneficial to increase the yield.

VI. Replenish seedlings

After the emergence of sand ginger, it is necessary to check the emergence of seedlings in time and make up the lack of seedlings in time. In order to ensure the completion of seedlings, appropriate amount of fertilizer can be applied, such as soil consolidation can loosen the soil in time, which is more conducive to seedling emergence.

VII. Post-management

1. In the later stage, it is necessary to strengthen the field management. If the accumulation of water in the field can easily lead to the rot of sand ginger root and the disease of sand ginger blast, it is necessary to carry out drainage in time.

2. Weeding is generally carried out in May and September, and the root system of sand ginger should be avoided as far as possible to avoid the invasion of germs. the disease peak period is from June to August, and weeding should not be carried out at this stage, but should focus on the control of diseases and insect pests.
