Abstract:

Zhumadian is one of the main wheat-producing areas of Henan Province. The annual planting area is about 666700 hm2, accounting for 59.5% of the city's total grain area 1120000 hm2. The total wheat production keep staying beyond 40 billion kg, accounting for 1/8 in Henan Province, and play an important role in food security of Henan province and the country. Zhumadian is a special geographical position. The climate environment characteristics are obviously different from high yield areas’ in the north of Henan. The 1000-grain weight and grains per ear of the 3 yield components were low, which were main character restrictive factors for the yield. At present its average wheat yield was 6850.5 kg/hm2, which was far more than 5670 kg/hm2 in 2004. Although we made great progress in the in the past several years there was a problem calls for immediate solution, which was the production from years were unstable and unbalanced. This paper summarized the main problems about environmental effects on wheat and provide information for the high-yield key cultivation techniques.
