Tiny Drip Irrigation Pipe Makes Wider Water Saving Roads

noon in May 29th, when the reporter saw Wang Jianlin, he was cooling in his own side under

the shade.

"Did you almost finish it?"With four breakout peer Huangyang river farm fielder Li Huabin

came to ask. Wang Jianlin looked at his watch, "still need a few minutes. Come and have a

cool break."

Under the shade is the large maize field, with green maize seedling growing, but the whole

ground seemed not watered."Arent you watering? The ground looks dry ah?"The reporter

asked curiously.

"We are all using mulched drip irrigation in the cornfield, unless it is rainy, or from species to

receive you cant see a wet field."Wang Jianlin smiled, "we do not adapt to the time just in the

last year. How can no water be irrigated? Worrying about the crops to can't grow well, but to

the autumn, it is 200 catty more than the original with per mu!"

Huangyang River irrigation area is located in the middle reaches of Shiyang River Basin, in

the territory of Wuwei province Gansu city Liangzhou district while the Shiyang River Basin is

the largest population density of the inland river basins in China, water resources per capita

share is at the least. It is one of the most prominent area in the contradiction between supply

and demand of water resources. Therefore, vigorously promote water-saving agricultural

technology is particularly urgent in here.

Wang Jianlin invited the reporter to walk into the field and have a closer look. below each row

of corn plastic has a two-finger thick drip irrigation black pipe. He uncover the plastic film with

great care, and we can see the oozy drip wet the clay and along the formation of a "mud with

drip irrigation belt".

"I wondered that the drip irrigation can have several benefits."Mr.Wang, who used the drip

irrigation system equipment last year, told reporters with crossing his fingers. "the first is a

save of labor. With flood irrigation, you need always worry about the changing water leakage

and nobody has time to have a break. But using drip irrigation equipment, when it is my turn,

what me need to do is to open the water can which is at the edge of the field. Second is yield.

Because drip irrigation can make water and fertilizer distribution more uniform the crops can

assort better. Using the drip irrigation, the average per mu corn yielded to 1400 kg last year

while flood irrigation is only 1200 kg. Third, the most important is the water. Flood irrigating

need water 5 times every year, and 100 multi-party per mu, so that in one year it need at

least 600 square water; drip irrigated 7 times a year, but a mu of land each needs only about

20multi-party of water throughout the year, a less of 200 square water is enough."

Li Huabin says, "In recent years the country are of implementation of key management in

Shiyang River Basin. With more water saving in Irrigation District, the greater contribution of

ecological governance downstream Minqin Oasis of light field has. We have 10000 acres of

drip irrigation of crops this year in our square".

The reporter acknowledged that, along with the "planning" implementation of key

management in Shiyang River Basin in depth, plenty of water saving projects are completed

in the Liangzhou area of Shiyang River Basin in the irrigation area. The conventional field

water-saving irrigation project area are 930000 mus, while drip irrigation project occupies

more than 80 thousand mu and 56.4thousand mu of greenhouse drip irrigation project.

Among them, the drip irrigation technology applied in solar greenhouse water-saving effect is

more outstanding.

Walking into the rural village in Liangzhou District of Wuwei Baili seedling Co. Ltd., the

sunlight greenhouses with high standard are particularly conspicuous. At here is not only to

provide seed for the surrounding farmers, but also the development of masses of

greenhouse, provide technical guidance.

"We have two gutter-connected greenhouses, 7 arched greenhouses, and 12 high standard

greenhouses at present, when it was first built in 2008, it is still using furrow irrigation and till

last year the transformation of drip irrigation under film completed."Wuwei Baili seedling Co.

Ltd. manager Zhang Wenhong told the reporters that, greenhouse planting environment need

to drip irrigation technology better."A mu of land each year needs 600 square water irrigation

greenhouses, and then use the high ridge double can reduce to about 260 square. Now the

high ridge single every year only need 200 squares of water."

It has another beneficial in using drip irrigation in the greenhouse. It can effectively reduce

the incidence of crop diseases and insect pests."Each greenhouse is an independent small

environment. furrow irrigation can cause high humidity and bad temperature control. So that

it is easy occur the root rot and Botrytis cinerea; the use of drip irrigation under plastic film

can make the surface can not see the water, can be a better control to the small

environment." Zhang Wenhong made a vivid parable, "if a person is sweating, pour a bowl of

cold water on the head and it will certainly to bowel bad. But if the use of shower slowly

washing it will be no problem wjncygy^."

At the same time, the application of the sunlight greenhouse water-saving technology can

effectively save the artificial."In the past, water a greenhouse needs two to three people, and

now one person can poured 5 greenhouses at the same time."Zhang Wenhong said, "The

development of modern water-saving agriculture is inseparable from the efficient water-

saving technology supporting the corresponding, so as to achieve benefit, ecological,

harmonious win-win development of artificial."
