Analysis of the feasibility of extension of the technology of pepper drip irrigation under film from the view of cost and benefit--Using Baodi district,Tianjin city as an sample area
For agriculture,water is the lifeblood,agriculture can not exist without water.China is a large agricultural country,40%of the cultivated area can only function normally through irrigation.As a new irrigation way,drip irrigation under plastic film promotes a series of changes in agricultural production,becoming a turning point to modern agriculture.This study combines practical study with field survey,choosing the particular Bohai region with typical climates in North China as the research spot.The main objects of this stud-y are those villagers in a certain town of Baodi district,Tianjin city.The main study method is statistics.Based on the calculation model of water-saving irrigation ,This study discusses the feasibility of the extension of technology of drip irrigation under film with the assum-ing characteristic that pepper plants need water in semi-humid water-deficient area.This study aims to provide reasonable suggestions about developing and promoting the technology of drip irrigation under film and the technology of agricultural water-saving irrigation technology.
