Brief introduction of maize variety Xianyu 335

Xianyu 335 maize is a maize hybrid bred by American Pioneer Company. This corn variety is exclusively produced, processed and sold by Dunhuang Seed Pioneer thoroughbred Co., Ltd. according to the quality standards and proprietary technology of Pioneer Company of the United States.

Xianyu 335 has the advantages of high and stable yield, lodging resistance, wide adaptability, moderate maturity and reasonable plant type.

This maize variety passed the national examination and approval in 2004, and soon spread in Northeast China, Northwest China, Huanghuaihai and other places. In 2006, the national planting area was only 260,000 mu, reaching 810.6 million mu in 2008, increasing to10.9 million mu in 2009, and the promotion area in 20 10 reached more than 30 million mu.

Xianyu 335, together with Zheng Dan 958, has become the two leading varieties in Northeast China and Huanghuaihai region. The annual promotion area is more than 350 thousand mu, and it is still one of the leading varieties in Huang-Huai-Hai area.

Characteristics of maize seed Xianyu 335

① growth period

The growth period of Xianyu 335 maize in Northeast China is about 127 ~ 130 days, and the accumulated temperature is about 2750℃. This variety belongs to the middle and late maturity variety.

② Good adaptability.

Xianyu 335 maize has the advantages of good adaptability, strong disease resistance and lodging resistance, high yield, good quality, deep and fine grain, fast dehydration and heavy grain.

③ High yield.

Xianyu 335 has the advantages of high yield, good quality, fast dehydration, high seed yield, high bulk density and moderate ear position, which is suitable for mechanized harvesting, and the yield advantage is 5% ~ 10% higher than that of local varieties.

In 2002-2003, he participated in the regional trial of summer maize varieties in Huang-Huai-Hai, which increased the yield by 38 points and decreased the yield by 7 points. The average yield per mu in two years was 579.5 kg, which was 1 1.3% higher than that of the control agricultural university.

In 2003, he participated in the same group production test, which increased the yield by 15 points and decreased the yield by 6 points, with an average yield of 509.2 kg per mu, which was 4.7% higher than that of the local control.

④ Good disease resistance.

After two years of inoculation and identification by the Plant Protection Institute of Hebei Academy of Agricultural Sciences, it is highly resistant to stem rot, moderately resistant to smut and Curvularia leaf spot, and susceptible to big leaf spot, small leaf spot, dwarf mosaic and corn borer.

Key points of maize sowing technology in Xianyu 335

Xianyu 335 has wide adaptability and can be planted on both flat land and sloping land, but it needs to strengthen the cultivation management level to obtain higher yield.

rational close planting

Xianyu 335 is a density-tolerant variety, and the planting density can be appropriately increased. Generally, there are about 5000 plants per mu, and different regions should adapt to local conditions.

Over-diluted output reaches the predetermined target. Excessive density causes poor lighting and ventilation, fiber plants, and even the threat of strong winds, causing lodging and greatly reducing production. Therefore, choosing suitable density is one of the important measures to resist wind disaster.

Fertilization method

In order to maximize the yield of Xianyu 335 corn, pure nitrogen 150- 175 kg, pure phosphorus 75-90 kg and pure potassium 90- 100 kg should be applied as base fertilizer per hectare. Topdressing urea 150-200 kg/ha at the big bell mouth stage.

Timely harvest

Xianyu 335 maize variety is generally harvested at the full maturity stage, which is characterized by loose ears and bracts, hard and bright seeds and black layers.

If the harvest is too early, the yield will be reduced to varying degrees, and if the harvest is too late, the straw will touch the ground and become moldy, resulting in losses.
