How to sow the seeds of Gaodan grass? What are the cultivation methods?

Gaodan grass is a new forage grass newly approved by the third National Herbage Variety approval Committee according to the principle of heterosis and hybridized with sorghum and Sudan grass. Gaodan grass combines the advantages of sorghum stem diameter, leaf width and strong tillering ability and regeneration ability of Sudan grass, and the heterosis is very obvious. So how to sow the seeds of Gaodan grass? What are the cultivation methods? Next, let's have a look with the editor.

How to sow the seeds of Gaodan grass?

Gaodan grass seeds are oval, and the sowing time is generally chosen in spring, that is, between Qingming and Grain Rain, when the low temperature is 15 degrees Celsius, which is the right temperature for Gaodan grass seed germination.

Gaodan grass is a temperature-loving plant, which is not resistant to drought at seedling stage, and the suitable growth temperature is 24 ℃-33 ℃. It has strong disease resistance and strong regeneration ability, and can cut 3-4 crops a year. Hay contains more than 15% crude protein and high sugar content, so it is suitable for silage. All kinds of livestock and poultry like to eat, and the grass supply period is from May to October.

2. Cultivation methods of Gaodan grass.

1. Sowing date

Suitable soil temperature 15 degrees, suitable for spring sowing, Qingming Festival to Grain Rain is suitable.

2. Sowing method

It can be broadcast by strip or hole. The sowing rate of 667 square meters is 1.5-2.0 kg, the sowing depth is 3 cm, and the row spacing is 15-30 cm.

3. Field management

Before sowing, the soil should be carefully prepared and sufficient base fertilizer (5000 kg / mu organic fertilizer) should be applied. After emergence, interseedling and fixed seedling were carried out according to the requirement of density, and 30-50,000 seedlings could be retained in 667 square meters. The first cutting should be carried out 35-45 days after emergence, and the early yield was low, and the late stem aging affected the recurrence, and then it could be cut again every 20 days or so. It can be cut 4-7 times a year. In order to ensure the high yield of fresh grass all the year round, the stubble height should not be too low for each cutting. Generally, the stubble height should be 10-15 cm, and 1-2 nodes should be left on the ground. Topdressing should be carried out after each cutting, usually about 8 kilograms of urea per 667 square meters. After emergence, the seedlings should be ploughed for 1 or 2 times, and the weeds should be ploughed in time after each cutting. Gaodan grass has a yield of about 10000 kg of fresh grass with a high yield of more than 20000 kg.

The above is the introduction of Gaodan grass. Gaodan grass has high nutritional value, good palatability, strong regeneration ability and strong tillering ability. under irrigation conditions, the north can be mowed 1-2 times, the yield of fresh grass per mu is 6000-9000kg, and the south can be mowed 3-4 times, the highest yield of fresh grass per mu is about 13 tons. It is suitable for silage, silage, direct grazing and hay preparation. Gaodan hay contains crude protein and high sugar content, so it is suitable for silage. It can be used to raise cattle, sheep, rabbits, geese, fish and other livestock and poultry. The production shows high quality and high yield, and the benefit is obvious.
