Seed price and planting method of Setaria angustifolia

Setaria przewalskii is a common weed in dry land, which is distributed all over China. Despite the fact that dogtail grass is inconspicuous, its culms and leaves can be used as fodder and have a certain medicinal value. The whole dogtail grass boiled in water can be used to kill cabbage worms. Let's learn about the seed price and planting method of Setaria angustifolia.

I. seed price of Setaria villosa

The market price of Setaria przewalskii seeds has been very stable, the price per jin of seeds is about 75 yuan to 90 yuan, this price is still very low, or within the acceptable range. The increase or decrease in seed yield of Setaria viridis in the same year. Wholesale is cheaper than retail for the amount of purchase. Prices will be on the high side in the peak planting season. The seed prices of different batches, different specifications and different producing areas are also different.

2. Planting methods of Setaria angustifolia

1. Seed selection

Select high-quality, full-grained seeds of Setaria viridis.

2. Sowing time

The best sowing time of Equisetum equisetifolia seeds is from February to May and from September to October every year, and the germination rate and growth rate of the seeds sown at these two times are the highest and the best.

3. Soil preparation and fertilization

Before sowing, Setaria przewalskii requires soil preparation and fertilization, first using herbicides or manual removal of weeds, fine soil preparation, applying 1000-1500 kg organic fertilizer and 15-20 kg phosphate fertilizer per mu as base fertilizer.

4. Sowing and raising seedlings

Setaria przewalskii is propagated with seeds, sown in mid-late June, sowed or withdrawn, with a row spacing of 30 cm, a depth of 1 cm, and a sowing amount of 1 jin per mu, covering and pressing seeds after sowing.

5. Ploughing and weeding

The seedlings of Setaria angustifolia grow slowly and are fragile, while weeds grow vigorously in spring sowing grassland, so weeds should be ploughed and weeded twice in the early stage.

6. Cutting and topdressing

Proper topdressing of nitrogen fertilizer after each use or cutting will significantly promote its regeneration and improve the quality of the grass, and topdressing is the safest 5-7 days after cutting.

7. Disease and pest control

Setaria przewalskii has strong resistance to diseases and insect pests, rarely occurs diseases and insect pests, but there are also locusts, crickets and other insect pests, we should pay attention to prevention and control.

Third, the harm of Setaria villosa

Compete with agricultural materials for water, nutrients and light energy: weeds have developed roots, strong ability to absorb soil water and nutrients, and strong growth advantages, and water and fertilizer consumption often exceed the consumption of crop growth. The growth advantage of weeds is strong, and the plant height is often higher than that of crops, which affects the utilization and cooperation of light energy, interferes with and restricts the growth of crops.

Weeds are the intermediate hosts of crop diseases and insect pests: many weeds are annual or perennial plants. Germs and pests parasitize or winter on weeds or roots all the year round, and then migrate to crops in the following spring.

Reduce crop yield and quality: due to the direct and indirect harm of weeds (spread of diseases and insect pests), crop yield and quality will be significantly affected.

Affect the health of people and animals: such as wheat field weeds poison wheat and seeds, which contain poisonous wheat alkaloids, which can cause poisoning to people and livestock when mixed into wheat grains; Xanthium sibiricum seeds also contain toxic substances, which can cause poisoning to people and animals after eating a large amount by mistake.

Increase management labor and production costs: the farmland with more weeds consumes more labor for weeding, and at the same time, due to a large number of labor, the production cost is increased.

Dogtail grass, commonly known as hairy dog, is one of the dominant species of weeds in orchard, with strong fecundity and serious harm.
