We can choose different forage to feed the livestock at different times. Many grasses have good nutrition and palatability, which can promote their growth and development, improve their disease resistance and survival rate, and feed cows can increase milk production.
Planting grass should be adapted to local conditions. Many grasses have high yield and good nutrition. Sweet sorghum is a high-yield and high-quality forage grass in Gramineae, which can be mixed with concentrate and straw to feed cattle and sheep with good weight gain effect.
Feed sweet sorghum, named after its rich sugar content in the stems, is rich in nutrients, especially calcium and phosphorus, which are higher than those of silage corn.
Feed sweet sorghum has large leaves, thick stems, many leaves, high protein content, sweet stems, high nutritional value and good palatability. It can be directly fed as green feed and silage, which is very popular among all kinds of domestic animals, especially cattle and sheep.
Forage sweet sorghum has strong stress resistance and adaptability, and its yield is relatively resistant to waterlogging in arid saline-alkali soil, so it is called "camel in crops".
Sweet sorghum has strong tillering ability and good regeneration, which can be widely planted in arid areas with irrigation conditions in the north, and can also adapt to the high temperature and rainy climate conditions in the south.
Sweet sorghum can grow above 10℃, and the accumulated temperature reaches 2600℃-4500℃.
It has a large biomass and belongs to high-energy crops. The yield per mu of land is 10~ 15 tons, and it can harvest more than one crop a year, which is obviously more than twice that of silage corn.
Photosensitive sweet sorghum variety "PPS" belongs to brown midvein "BMR", with low lignin solid content and high digestibility. One plant can produce 40 or even 40 leaves in the whole growing season, which is a good forage for cattle and sheep in spring.
Sweet sorghum forage seeds: forage sweet sorghum planting method: 1, sowing date: sweet sorghum is mainly sown in spring, the sowing date is from March to May, and the average temperature is about 15 -20 degrees.
Premature sowing affects germination, and late sowing affects yield.
2. Sowing mode: It can be either machine sowing or on-demand, and the sowing depth is generally 3~4 cm.
The spacing between sowing holes should be kept at 15 ~ 20cm. If the soil is wet, you can sow it lightly, if the humidity is low, you should sow it deeply. After sowing, cover the soil or compact it with fine sand, and water it properly.
3. Sowing management: irrigate sweet sorghum for 3-5 times during the whole growth period.
The 1 irrigation is used to irrigate the moisture content of soles, and the moisture content at the bottom is mainly flooded, so as to ensure sufficient irrigation and thorough irrigation.
The second irrigation is carried out at jointing stage about 25-30 days after sowing, combined with intertillage and topdressing; The third irrigation is usually 15 days after the second irrigation; The fourth irrigation is usually carried out at the filling stage of sorghum.
(Harvesting for many times, watering each time) Before sowing, fill enough water to ensure seedling qi and Miao Zhuang.
After emergence, irrigation time should be decided according to plant growth and weather conditions.
Late irrigation, to prevent water accumulation in low-lying areas, especially pay attention to weather changes, to prevent lodging.
