High-yield cultivation techniques of Highland Barley

Highland barley is a kind of cereal crop, also known as naked barley, yuan barley, rice barley, mainly produced in China's Xizang, Qinghai and other places, is the staple food of Xizang people. If you want to improve its yield when planting, you need to start from many aspects. Let's take a look at the high-yield cultivation techniques of highland barley together with Xiaobian.

1. Know

Soil preparation is a very important part of the cultivation process of highland barley, especially after harvest, it is necessary to carry out deep weeding of weeds. In spring sowing is to carry out shallow ploughing, lest the land affect the growth of highland barley, in order to facilitate the growth of highland barley, if it is autumn sowing, sowing time had better choose autumn harvest half a month, cultivated land should be timely clean up diseased plants, autumn planting also need to carry out deep ploughing, at least 20 centimeters or more. This can effectively eliminate weeds and pests, it can also play a role in cold protection, but also can better maintain soil fertility and reduce the impact of autumn drought. At the same time, the specific conditions of the land can also be used for border or ridging, and after soil preparation, it should be sterilized once to reduce the number of diseases and insect pests as much as possible.

2. Sowing seeds

The varieties with good characters should be selected before sowing. They have strong adaptability and can survive in harsh climatic conditions. At the same time, the seeds need to be dried. Adding seed coating in sowing can not only improve the survival rate of seedlings, but also prevent them from being attacked by diseases and insect pests in the process of growth. If it is alpine areas, generally choose to sow in mid-late April, while semi-alpine areas can sow in mid-March, the sowing depth is generally about 5 cm, too deep and too shallow are not conducive to seed germination.

3. Fertilization

When fertilizing, the mixed fertilization technology should be used according to the actual situation. First of all, the organic fertilizer should be evenly mixed before planting and sealed for about 7 days. The compound fertilizer must contain elements beneficial to the growth of highland barley, such as nitrogen, phosphorus and potassium. Generally, only 400-500 kg of fertilizer is needed per mu. When highland barley heading, there is no need to apply nitrogen fertilizer, which may cause late ripening. In the later stage of growth, the root system gradually aging, the absorptive capacity decreased, so it is easy to appear premature senescence, so it is necessary to apply foliar fertilizer in time to supplement the nutrients needed by the plant, promote root growth and effectively prolong the leaf function.

The above is the introduction of highland barley high-yield cultivation techniques, hope to help you, want to know more related knowledge, please pay attention to us.
