How to select barley seeds? What are the methods of raising seedlings?

Barley is actually a crop, growing in a wide range of environments, and has spring and winter growth habits. Barley is also one of the oldest cultivated crops in the world. It has many uses such as food, feed, brewing and medicine.

How are barley varieties classified?

1. Cultivated barley has three species: barley hexaseriac, its flower ear has two opposite grooves, each groove bearing three spikelets, each spikelets bearing a flower, seed 1. Barley in two rows is biseriate, with a central floret in the spikelet that can bear seeds, and lateral florets that are usually sterile. Irregular barley or Abyssinian intermediate, rarely cultivated, fertile central flower, fertile or sterile lateral florets.

2. Barley is a generic term for both glume barley and naked barley. Generally, barley with palea is called barley with skin, which is characterized by adhesion of palea shell and grain; naked barley is separated from palea shell and grain, which is called naked wheat, Qinghai-Tibet Plateau is called highland barley, Yangtze River Basin is called raw wheat, North China is called rice wheat, etc.

3. Barley in the botanical classification of Gramineae-barley genus. Economic value is common barley species in two subspecies, namely two-rowed barley subspecies and multi-rowed barley subspecies. Usually we call multi-rowed barley six-rowed barley. Barley, two-rowed, triple spikelets on each node of rachis, only middle spikelets bearing fruit, lateral spikelets incomplete or degenerate, unable to bear fruit. The number of grains per ear of two-edged barley is small, and the grains are large and uniform. Two-rowed barley is usually planted in the Yangtze River basin in China. Six-rowed barley, triplets on each node of the rachilla all bearing fruit. Generally, the middle spikelet develops earlier than the lateral spikelet, so the grain of the middle spikelet is slightly larger than that of the lateral spikelet. Because of the different density of triplets on the spike axis, there are three types: sparse (7~14 in 4 cm), dense (15~19 in 4 cm) and extremely dense (more than 19 in 4 cm). Among them, trisomy spikelets are sparse, and the cross section of the spikelets has 4 angles. People call it 4-rowed barley, but it is actually sparse six-rowed barley.

II. What are the methods of barley seedling cultivation?

1. planting time

Barley seeds can be sown in spring and autumn, February to May is suitable for spring sowing, August to October for autumn sowing, these two climatic conditions are more suitable for seed germination, can have a higher germination rate. Barley is not as strict as wheat in terms of sowing time and is a well-maintained plant.

2. Seed selection

The first thing to grow barley is to select high-quality seeds. Good seeds are the prerequisite for everything, which can make the germination rate higher and thus affect the final yield. It is best to choose barley seeds harvested in the same year, and the aging of seeds should not exceed three years, otherwise it will seriously affect the germination and reduce the yield. Only by selecting mature and plump new species for planting can yield be guaranteed.

3. planting soil

Barley does not require high soil requirements, but it is still necessary to refine the land before sowing. It is necessary to plough the planting land, make the soil fine, and apply sufficient base fertilizer to keep the soil fertile, which is very helpful for seed germination and subsequent growth.

4. precautions

After all the preparations are done, it is necessary to start sowing. Barley seeds are generally broadcast directly. It should be noted that seeds cannot be buried too deep when sowing, otherwise they will affect germination. The depth should be controlled at about two or three centimeters. After sowing, management should be done well. Barley likes to be wet and should be watered properly. However, drainage should be done well in rainy season, otherwise soil ponding will cause great problems.

In fact, barley is a very good food crop, both edible value and medicinal value, farmers who choose to plant barley can consider varieties according to the local ecological environment.
