Planting technology of highland barley

Highland barley is a kind of cereal crop of Gramineae, which is mainly concentrated in Yunnan, Xizang and other areas of China. Is the main diet for the majority of Tibetan people, highland barley has a rich nutritional value, and also has a certain medical role, now in China has nearly 4000 years of planting history. So how to grow highland barley? The following editor brings you the planting technology of highland barley, let's have a look!

1. Soil preparation and fertilization

Highland barley because of different planting areas, its soil, planting methods and weather will be different. The previous crops of highland barley soil should be potato, corn and so on. After harvesting the previous crops, we should pay attention to do a good job of soil preparation, the deep roots of the soil about 22 cm. Reasonable soil preparation before sowing is beneficial to improve the germination rate of highland barley seeds. Then in the soil preparation, we need to apply sufficient base fertilizer, and the base fertilizer should be reasonably equipped with farm fertilizer and nitrogen and phosphorus fertilizer to meet the nutrition needed for the growth of highland barley. Then the fertilizer and the amount of fertilizer should be adjusted reasonably according to the structure type of soil and production.

2. Seed selection and sowing

A good seed is the key to ensure the high yield of highland barley. When selecting varieties, we should pay attention to selecting a suitable seed according to the local soil environment and weather. The sowing time of highland barley should be early, and the sowing time should be controlled according to the altitude. For example, the sowing time of highland barley in 2700-2800 should be carried out around March. And different varieties have different sowing seasons. When sowing, we should pay attention to control the sowing density to ensure that each robust seedling has sufficient growth space after emergence. The main sowing method is ditch sowing, and the sowing should be properly covered with soil and watered to promote seed germination.

3. Seedling management

After the highland barley seedlings are unearthed, we should do a good job of checking and replenishing the seedlings, remove the overdense seedlings, and fill the seedlings with the same growth at the hole of the lack of seedlings to ensure that the whole seedlings are uniform. Then we should pay attention to do a good job of weeding, reasonable weeding is the key to ensure the healthy growth of highland barley. Chemical weeding is generally the main method, so attention should be paid to the use of herbicides when weeding. It is usually combined with intertillage and weeding when the seedlings grow to about 4 seedlings. And we should also pay attention to the prevention and control of diseases and insect pests, enhance the growth capacity of highland barley and increase the yield.

4. Water and fertilizer management

The purpose of watering and fertilizing is to meet the nutrient demand of highland barley during its growth. In the seedling stage, attention should be paid to reasonable watering to promote the differentiation and growth of young spikes into large spikes. Then in the heading stage, we should appropriately increase the amount of water to promote the fullness of highland barley particles and improve the accumulation of nutrition. When fertilizing, the amount of fertilizer should be adjusted reasonably according to the growth of seedlings and soil and other factors, preferably with watering. We should pay attention to control the amount of nitrogen fertilizer, although the right amount of nitrogen fertilizer can promote the growth of highland barley, but excessive it is very easy to lead to overgrowth of highland barley.

The above is a brief introduction of highland barley planting technology. The planting technology of highland barley is actually relatively simple, but due to the special growth environment, it can not be planted in many places, so we can not plant blindly! That's all for today's introduction. This article is for reference only. I hope it can help you all.
