How to grow Sudan grass
Sudan grass is an annual herb of the genus sorghum. Today, the editor is going to introduce to you how to plant Sudan grass. Let's take a look!
First, how to grow Sudan blue
Seeds with full grains and no diseases and insect pests can be selected and dried for a day or two before sowing to improve the germination rate of the seeds. The sowing time is concentrated from early April to June, which can ensure the continuous production of green feed throughout the summer. Nutrients need to be absorbed from the soil throughout the growing period, so topdressing should be done in time according to the growth situation. Field management is mainly to clean up weeds and harvest them at the right time.
II. Propagation methods of Sudan grass
1. Rust spot
Rust-colored spots appeared on the leaf surface, initially at the tip of the leaf surface, and then gradually expanded to the whole leaf surface, and spread to other leaves and other plants, resulting in the death of leaves; the nutritional value decreased greatly, or even no nutritional value.
Preventive method: soak the purchased seeds with antibiotic drugs, and the preventive effect can be achieved by adding 200 times of Jinggangmycin water. Treatment: Jinggangmycin plus water 1000 times foliar spray for 2 consecutive days, preferably in a sunny afternoon, 3 days can be cured, and then once every 15-20 days. The medicine can be fed after 2 days. [7]
2. Mildew rot
At the initial stage, the stems and leaves at the tillers of the roots were moldy and spread to the dense middle stems and leaves, resulting in mildew and death in the roots of the plant, and only a few parts of the edge grew normally. In severe cases, they no longer tillered, and the whole plant rotted and died at the roots.
Preventive method: uniform nest sparse planting. Due to the strong tillering ability of Sudan grass, it can evenly nest after growing 3-4 leaves, leaving 2-3 plants per litter, which can prevent mildew rot.
