How is the Liyu 16 corn variety? Variety characteristics and yield analysis

The Liyu 16 corn variety performs quite well in the Huang-Huai-Hai region. Its plant type is semi-compact, the stalks are sturdy, and the root system is relatively well developed. It is a medium-maturity hybrid suitable for planting in Hebei, Shaanxi, Anhui, Henan, Beijing, Jiangsu, Shanxi and other regions. So what are the key technical points for planting it?

What are the key points for planting the Liyu 16 corn variety?

1. Sow at the right time

For summer sowing, sow generally in mid-June, with a seeding rate of about 3 kg/mu.

2. Plant at a reasonable density

When grown alone, the suitable density is about 3500 plants/mu.

3. Fertilize scientifically

Use nitrogen, phosphorus and potassium together. Pure nitrogen is generally 20-25 kg/mu, of which the base and seedling fertilizer accounts for 60% and the ear fertilizer 40%. Fields with poor fertility can be given an appropriate application of grain fertilizer. In the middle and late stages, pay attention to preventing waterlogging and drought, and in conjunction with fertilization, carry out timely intertillage and build up soil around the roots to prevent lodging.

4. Pest and disease control

Treat the seeds with chemicals and pay attention to controlling underground pests; do a good job of controlling the Asian corn borer, maize rough dwarf disease, banded leaf and sheath blight, and southern corn leaf blight.

In addition, corn maturity generally goes through three stages: the milk-ripe stage, the dough stage and the full-ripe stage. Everyone should harvest at the right time according to the situation, so as to further increase the yield.
