Practices on the Rain Fed Land Agricultural Development in Heilonggang Area of Hebei Province

摘要

Hebei Heilonggang area is located in the northern part of Yellow rivcr-Huai River Plain including 50 counties or cities in 2.4 million ha crops land, Water shortage is a main problem of agriculture production. Rain fed land is accounted for a half of total farmland, and agriculture development in rain land is very important. This paper covers the rain fed land fanning development ways or measures in Heilonggang area based on the dry land farming research and practices and local climatic and agriculture conditions, the major measures of rain land agriculture development and as the follovvings: 1: Adjust planting pattern to cereal, economic and forage three type -structure, for the regional rainfall effectivity and whole agriculture development; 2. Use soil water storage function fully and develop irrigation, scheduling and soil water conservation for increasing water use efficiency; 3. produce wheat area in rain fed land and increase the crops that the rainfall can meet its vigorous growth stage to improve crop drought resistance ability; 4. improve fertilizer application to increase limited water use efficiency; 5. utilize the chemical control technique to increase crop drought resistance ability and reduce water loss from ET. The above measures must be employed integratedly to improve the water resource use efficiency and prompt sustainable agriculture development in Heilonggang Area.
