It is necessary to choose ginger varieties with high yield and suitable for local cultivation. If the ginger is large, it is best to cut it with a clean knife. After incision, lime can be applied to the incision to achieve the purpose of disinfection. If we want to achieve the goal of early germination of ginger seeds, we can accelerate the germination appropriately.

Generally speaking, after the ginger is dried in the sun for two days, it can be soaked in a proper amount of Bordeaux solution for about 10 minute, then the ginger is piled in wet sand, covered with plastic film, and the temperature is kept at about 25 degrees, and it can germinate in about a week.

2. Avoid contact between seeds and base fertilizer.

In order to avoid direct contact between ginger and base fertilizer, the base fertilizer pot was covered with about 1-2cm of soil and arranged along the direction of bud entering the ridge. Please pay attention to this step (it must be the bud eye inside, which is related to the cost). Plant 2 rows per ridge, with row spacing of 15-20cm and row spacing of 30-35cm, and then cover the soil with 4-5cm to keep the soil moist.

3. Take back the planted ginger

When the ginger seedlings grow 4-6 leaves, slowly dig until you see the ginger seeds, then press the soil at the root of the ginger seedlings with one hand, break out the planted ginger and bury the soil back; The recycled ginger can be sold at a low profit. This method is true and effective, without exaggeration.

4. Planting process

When planting ginger, drilling can be used. When sowing, ginger buds should be placed upward as far as possible to facilitate growth. The distance between plants should not be too close, which is about 30 cm under normal circumstances, so that the growth space of roots is larger and the row spacing is about 40 cm, which is convenient for fertilization.

After sowing, cover it with soil, and the soil layer should not be too thick to avoid ginger being difficult to drill through on the ground. It is best to cover with a layer of straw to keep warm. When ginger was first planted, the temperature was low. Straw can protect ginger from wind and rain, and ginger can be turned into fertilizer when it grows, killing two birds with one stone.

5, fertilization

In the growing period of ginger, the basic fertilizer is usually applied first, and then the third fertilizer is applied. The first fertilization is the base fertilizer before planting, mainly compound fertilizer. This time, the fertilizer should be enough to support the growth of ginger. It should also be topdressing in time according to the growth state of ginger during the growth period to ensure that the yield will not be reduced due to insufficient fertilizer.

6, pest control

The main diseases that harm the growth and affect the yield of ginger are rot and spot disease. Rot usually lasts from August to early September in summer. If plants are found to be infected, the nearby soil should be removed to avoid bacterial infection, and then a layer of lime should be sprinkled to fill the ground with soil.

The control method is to spray 50% Bacillus solution 800 times every 7- 10 day. The main pests affecting quality are ginger moth and ginger maggot. You can spray the leaves with trichlorfon or phoxim.

Step 7 harvest

Generally speaking, the harvest season is late autumn and winter solstice, that is, 165438+ October and 65438+ February. At this time, it is necessary to observe whether the stems and leaves of ginger have turned yellow or withered. If so, it means it's time for ginger to be harvested.

But it is best to harvest it every two years. After all, ginger is still old and spicy, which means ginger is older. In fact, the stem of ginger is edible. It can be used to make ginger or directly fried, and it is also delicious.
