COMPARATIVE WINTER INSULATING VALUE OF SEVERAL SNOW DEPTHS, STRAW AND PLASTIC MULCHES

Spring maize yield, soil water use and water use efficiency under plastic film and straw mulches in the Loess Plateau

To compare the soil water balance, yield and water use efficiency (WUE) of spring maize under different mulching types in the Loess Plateau, a 7-year field experiment was conducted in the Changwu region of the Loess Plateau. Three treatments were used in this experiment: straw mulch (SM), plastic film mulch (PM) and conventional covering without mulch (CK). Results show that the soil water chan...

Plastic straw: future of high-speed signaling

The ever-increasing demand for bandwidth triggered by mobile and video Internet traffic requires advanced interconnect solutions satisfying functional and economic constraints. A new interconnect called E-TUBE is proposed as a cost-and-power-effective all-electrical-domain wideband waveguide solution for high-speed high-volume short-reach communication links. The E-TUBE achieves an unprecedente...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...

PEST MANAGEMENT Management of Aphid-Borne Viruses and Bemisia argentifolii (Homoptera: Aleyrodidae) in Zucchini Squash by Using UV Reflective Plastic and Wheat Straw Mulches

Plastic UV reßective mulch (metalized mulch) and wheat straw mulch delayed colonizationbyBemisia argentifoliiBellows&Perring and the incidenceof aphid-borneviruses in zucchini squash. No insecticides were used in either mulch treatment. The mulches were compared with a preplant treatment of imidacloprid and an untreated, unmulched control. In 2000, yield ofmarketable fruit in the plastic and st...
