The func-tions of shelterbelt net in omnibearing wind check and prevention of frostbite as well as the field of integrated climate effect within shelterbelt net were analyzed, through located observation of meteorological factors. Within the shelterbelt net, the area with more than 10% efficiency of omnibearing wind check was determined as benefited area. The analysis of yield and quality of crops indicated that the sheltering range of shelterbelt net was 25 times tree height. The mature heights of the various varieties of poplar composed the shelterbelts were determined according to their height growth. Based on the comprehensive analysis above, the suitable size of farmland shelterbelt net in Northeastern Plain of China was decided to be 400 m×400 m.展开更多

The results of this work showed that infestation by the confused flour beetle with 5 pairs of adult stage and its progeny within 3 months period may cause high deterioration and damaged of the flour specification. The people in lraq get their flour from some official and non-official mills which they produce not so good quality of this flour in addition to which it contains some times an infestation with the two species of the flour beetles T. castaneum and T. confusum, when people do not use this quantity as quickly as possible during this period of storage, the beetles will be increased in numbers and make the flour unacceptable for any kind of pastes or bread. The infestation by this beetle causes great pollution to the flour by the ecdysial of larvae and a bad smell that it leaves on the flour and all its products.展开更多
