How much is the seed of elephant grass per jin? How do you plant it? How many cattle can be raised per mu?

Elephant grass, also known as purple pennisetum, is a large perennial tufted herb of Gramineae and millet family. How much is its seed per jin? How do you plant it? How many cattle can you raise per mu? I learned from Mr. Shen of Shuyang Seedling Company that the price of elephant grass seeds is about 20-30 yuan per jin.

How to grow elephant grass?

1. Use about 500 jin of straw per mu. When planting in a flat field or land, dig the planting ditch according to different row spacing, the ditch depth is about 14 cm, and apply appropriate amount of farm fertilizer or calcium phosphate fertilizer to the bottom of the ditch as the base fertilizer.

2. It is appropriate to apply sufficient organic fertilizer as base fertilizer according to 1500-2500 kg / mu, 25 kg / mu calcium magnesium phosphate fertilizer and 5-10 kg / mu compound fertilizer. If the organic fertilizer is sufficient, the amount of chemical fertilizer can be reduced appropriately.

3. Generally, when the average temperature reaches 13-14 ℃, the seed stem can be planted with 2 rows per row, the plant distance is 50-60 cm, and the seed stem can be placed flat, or the buds can be inserted obliquely upward, leaving at least two nodes (bud eyes) for each seed stem and covering 6-10 cm of soil.

4. generally, seedlings can emerge at 7-10 days after planting, and tillering begins at 15-20 days. There are more tillers in fertile land, less in barren land, more in rainy season and less in dry season. Therefore, as long as there is sufficient water and fertilizer, high yield can be obtained. Elephant grass has strong tillering ability and fast growth. It is propagated by seed stem. The purpose of feeding is to consume about 1500 bud nodes / mu. After planting for one year, all the harvest bud nodes can be expanded to 500mu.

5. After each harvest of elephant grass, 1500-2500 kg / mu of farm manure was applied, 5-6 crops could be harvested in the high temperature area of the south, and the annual yield per mu reached more than 40000 jin.

How many cattle can be raised per mu of elephant grass?

One mu of pasture can raise 5 cattle, and 30 mu of land can raise 150 cattle.

Elephant grass is soft and juicy, palatable and highly utilized. Cattle, horses, sheep, rabbits, ducks and geese like to eat. It is also a good feed for raising pigs and fish. In addition to providing green fodder for livestock and poultry in the four seasons, it can also be made into hay or silage. Elephant grass has high nutritional value, high protein content and digestibility.

In addition, elephant grass can also replace coal and oil to generate electricity, and the energy generated by planting 1 hectare of elephant grass fuel can replace 36 barrels of oil, yielding at least 60 tons of elephant grass per hectare. The root system of elephant grass is well developed and planted on the edge of the pond and embankment can play the role of protecting the embankment and soil. Elephant grass can also be cut as a mulch for perennial crops. In a word, elephant grass has high yield, good quality, excellent palatability, long service life and wide use, and has high economic value. it is one of the good forage plants in tropical and subtropical areas.
