How to select and harvest oatgrass seeds? What are the cultivation methods?

Oatgrass, also known as bell wheat, belongs to Gramineae, oats. It is resistant to barren, drought and cold, has high feeding value, succulent leaves and straw, and good palatability. The straw contains 5.2% crude protein and 2.2% crude fat, which is a high-quality forage for cattle, horses and sheep in winter. It is very suitable for silage, silage or hay preparation. So how to pick and harvest oatgrass seeds? What are the cultivation methods? Next, let's have a look with the editor.

First, how to select and harvest oatgrass seeds?

Oatgrass seeds have a rich endosperm, a small embryo at the base, and the opposite side of the embryo is the hilum. If the 1000-seed weight is 2.3-3.5g, the germination rate of general seeds decreases greatly after one year storage, and the germination power is completely lost after 4 years storage. Oat grass should be harvested when the color of the ear changes from green to yellow. It can be harvested 375-750kg/ha. It is easy to fall off and should be harvested in time. Using fresh seeds in sowing can improve the rate of seedling preservation.

2. Cultivation methods of oatgrass

1. Rotation

Oats avoid continuous cropping and can be rotated with potatoes, peas, sweet potatoes, corn, sorghum, peanuts, sugar beets and other crops.

2. Land preparation

Oats are mainly sown in spring, sowing oats, and the quality of soil preparation should be good. Deep ploughing in autumn before sowing is one of the important conditions for high yield. 1500-2500 kg of organic fertilizer can be applied per mu.

3. Sowing seeds

The sowing time varies with different regions and cultivation purposes. In the north, it usually begins in early April and ends in early June. In warm areas, it can be replanted after summer harvest. The single sowing rate of oats is 10-15 kg / mu, and the green-cut oats can be densely planted properly, and the sowing rate can be increased by 20% and 30%. Generally, strip sowing is used, the row spacing is 15-30 cm, and the depth of soil cover is 3-4 cm. Oats should be mixed with legume crops such as peas and vetch, and the sowing amount of oats accounts for 2 to 3. 4. Seed soaking in warm soup can be carried out in areas where smut is endemic.

4. Field management

Mainly topdressing and irrigation. The principle of fertilization is that nitrogen fertilizer is the main fertilizer in the early stage and phosphorus and potassium fertilizer in the later stage, so as to prevent excessive growth and lodging. From tillering to jointing is the period that needs the most water, so we should pay attention to adequate water supply.

5. Disease control

The main diseases of oats are hard smut and rust, and the main pests are armyworm, locust, mole cricket, golden needle worm and grub, which should be detected and prevented in time.

6. Harvest

To harvest oat grain, the grain in the upper part of the ear should be fully ripe, while the grain in the lower part of the ear should be harvested when the wax is ripe, and the yield per mu can reach 100-150 kg. Green-cut oats can be cut from jointing to flowering, and can be cut twice. The first stubble is about 5-8 cm, generally yielding 1500-2000 kg of fresh grass per hectare. When drying hay or silage, it is appropriate to cut from milk stage to wax stage.

The above is the introduction of oatgrass, oatgrass has a wide range of uses, not only can be used as medicine, but also as feed, but also has ornamental value. In recent years, with the establishment of artificial grassland, oats began to be planted in pastoral areas and developed rapidly. it has become an important feed source of local withered grass season, favored by the majority of herdsmen, and the planting area is also expanding.
