drainage and irrigation work

Irrigation is important for farming.

The government authorized an irrigation project.

There the irrigation canal links up with the reservoir.

The set of opinion was toward building a new irrigation canal.

an irrigation scheme with dams, reservoirs, and channels.

a community cleanup project; a government-funded irrigation project.

the headwork and the irrigation system.The project effectively controls flooding and provides a method of irrigation.

He accomplished this by separating the project in to two main parts: the headwork and the irrigation system.

It is unanimous to design the multihole micro-irrigation pipe to variable diameter pipe withuniform pressure.

The irrigation technique is improved based on traditional irrigation technique adopting water-saving technique of trickle irrigator and spraying.

Ca absorption and tipburn of lettuce were studied under different application of N, K, Ca, sprinkler irrigation and border irrigation in open field.

The paper analyzes the soil water dynamics and water requirement law of alfalfa,feed maize and ensile maize under 3 kinds of water-saving irrigation conditions through experimental study on the crops.

Furthermore, N and P fertilizer application rate could be decreased accordingly to optimize fertilizer management when contributions from eutrophied irrigation water were taken into consideration.

The spatial differentiation of sediment granularity is controlled by micro-physiography formed by alluvion and deposit swing and by paleoclimate, and by, as well, human’s irrigation from Yellow River.

Since 2002, we begins the development and production of solar products, such as Solar Insect Killer, Solar Mouse &Bird Repeller, Solar Power Supply System, Solar Sprinking &Irrigation System, etc.

The results showed: inncrease application of Ca, balance application of N and K and sprinkler irrigation could increase Ca content of lettuce leaves, reduce occurring of tipburn.

Overpumping groundwater for drinking water and irrigation has caused water levels to decline by tens of metres in many regions, forcing people to use low-quality water for drinking.
