How to choose ginger seeds and what kind of ginger seeds have high germination rate?
The stem of ginger is divided into two parts: aboveground stem and underground stem. The aboveground stem is Jiang Miao, which is developed from buds on rhizome nodes. Underground stem is rhizome, which is an underground fleshy rhizome formed by the expansion of ginger stem base. It is the future reproductive organ, the main product organ or edible organ, and it stores a lot of nutrients. A complete rhizome is an irregular palm.

First, choose ginger seeds.

There are many varieties of ginger, and the varieties in different regions vary greatly. It is necessary to choose varieties with good growth and high yield, which are suitable for planting in this area. The market demand is similar to that of planting ginger. If the choice of planting ginger is improper, it will lead to irregular emergence and weak growth of ginger, which will seriously affect the yield and quality of ginger.

When choosing to plant ginger, we should choose healthy ginger with fat, fullness, bright color, tender meat, no shrinkage, no decay, no freezing, hard texture and no pests and diseases as seeds. The nutrition needed by ginger from germination to "three branches" mainly comes from planting ginger. Only when ginger grows strong can it provide enough nutrition, and before the root system of ginger absorbs enough nutrition, it can ensure the plant to grow well and avoid the shortage of nutrition supply. If the selected ginger is small, it can't reach the nutrition needed for the early growth of the plant, and the plant will inevitably grow weakly and the yield will be low.

For a piece of ginger, the number of buds mainly comes from terminal buds and lateral buds. Generally speaking, the side buds of the thin-seedling type succulent ginger are less than those of the dense-seedling type. The strong buds we need mainly come from the upper buds and side buds of growing ginger, which are fatter because of the top advantage, while the inner buds and base buds are generally thinner. When we sow ginger, we all hope to get strong ginger buds, and the health of ginger buds is not only related to the location of ginger buds, but also to the nutritional status of planting ginger and the temperature and humidity during germination.

Second, the main factors affecting the health of ginger buds

Generally speaking, the tender buds of ginger can be divided into three levels, that is, the big buds are more than 2 cm long and about 1 cm thick. Bud length 1? 2 cm, the middle bud thickness is about 1 cm, the bud length is less than 1 cm, and the thickness is 0.5? 0.07 cm small bud. What we want most is that the bud size is moderate to 0.5? 2 cm, 0.5 thick? 1 cm. From the morphological point of view, generally strong buds are white and bright, thick, short and fat, with blunt tips, and only root protrusions are seen at the base of buds, while weak roots are slender buds with sharp tips and slightly curved buds, and adventitious roots have occurred at the base of buds.

Want to promote ginger bud robust, mainly from the following aspects:

1, choose to grow ginger.

Only fat ginger can produce strong buds. In general, ginger balls are obese, and brightly colored ginger is rich in nutrition, and most of the buds on it are fat. Any kind of ginger with thin ginger balls has poor nutritional status, and its buds are mostly weak buds. Therefore, we should choose obese ginger slices as ginger seeds to cultivate strong buds.

2. Temperature and humidity during germination.

Environmental temperature and humidity are important factors affecting the quality of ginger buds during germination. Stay at 22? The temperature of 25℃ can make the buds fat and strong. If the temperature is higher than 28℃ for a long time during germination, the sprouted ginger buds tend to be very thin, just like white growth. When the temperature is lower than 20℃, ginger buds germinate slowly, which may affect the suitable sowing date.

The humidity during the germination of ginger also has a great influence on the bud. Too low humidity will lead to dehydration and shrinkage of ginger skin, while too high humidity will lead to mildew and rot of ginger buds, which will seriously affect the germination speed and the quality of young buds.

Generally speaking, the relative humidity of ginger during germination is 60%? 80%。 Under the premise of ensuring air permeability, the thickness of plastic film should be increased as much as possible to reduce water evaporation and ensure the smooth germination of buds.

Thirdly, the effect of seed bud size on yield.

The size of accelerating germination has a great influence on the growth and yield of ginger. Although the plants sown with small buds appear a little late, they grow vigorously in the middle and late stage, with suitable leaf area, strong photosynthesis and long photosynthetic time, which can give full play to the advantages of long growth period of ginger, thus increasing yield.

However, although the early growth of plants with big buds is stronger than that of plants with small teeth, the late stage is the key period for yield formation, but the plants with big buds are about 30 days earlier than those with small buds, which is exactly the saying, "the chain is broken at a critical moment", which not only inhibits the growth of stems and leaves of plants with big buds and reduces their photosynthetic capacity, but also shortens the time of high-intensity photosynthesis and reduces the accumulation of dry matter, resulting in a decline in yield.

The results of my experiments in 2007 and 2008 showed that the yield of ginger with medium buds and small buds was more than 20% higher than that with large buds. You can do an experiment if you don't believe me. One of the most obvious phenomena is that when you choose to plant a few beds of ginger with big buds first, do you find that in the later stage of ginger growth, Jiang Miao is obviously lower than that of middle plants with small buds? You can carefully observe the ginger management in the next season and see if I am right.

Secretly tell you a little skill, which can make your ginger germinate quickly, the emergence rate is high, and the number of seedlings on each piece of ginger increases.

Effect of Seed Soaking with Ethephon on the Growth of Ginger

Ethephon is mainly used for ripening tomatoes, watermelons and other fruits. According to many years of experiments, soaking ginger seeds with ethylene can promote germination to some extent.

It is necessary to control the concentration of ethephon to accelerate germination. With the increase of concentration, the number of ginger buds increased and the emergence rate also increased. Soaking ginger seeds with suitable concentration of ethephon will inhibit the growth of ginger at seedling stage, but after entering the vigorous growth period, the inhibition will gradually disappear and the growth potential will be obviously enhanced, which is characterized by tall plants, stout stems, many branches, large leaf area, thick leaves and increased fresh weight of ginger slices. But the concentration is too high, although there are many branches, the plants are short and the branches are fine, and the leaf area and fresh weight have a downward trend.

Years of practice have proved that soaking ginger seeds with ethephon for 15 minutes can obviously promote the germination of ginger, and the number of buds on each ginger seed block increases from 1 to 2? Three buds can increase production by 20? 30%。

In short, no matter how many buds you introduce, only 1 strong bud can be kept on each ginger seed, and two strong buds can be kept on several pieces of ginger, and all other young buds can be cut off. In the process of accelerating germination, the germination time of the same batch of ginger seeds may be different, and the ginger buds may be long or short. Growers should start selecting and sowing after all ginger seeds germinate. In production, ginger buds are allowed, but they cannot be dumb ginger without ginger buds, otherwise it will cause inconsistent growth in the field and ultimately affect the yield.
