The re-sults showed that droughts and floods had significant effects on crop growth and yield. In Puyang, the relieving and prevention technology of the disasters is con-cluded. Specifical y, it is recommended to make ful use of agricultural climate re-sources in a rational way and select suitable crop varieties according to climate and disaster characters, fol owed by timely sowing and scientific crop arrangement. What＇s more, ploughing should proceed in deeper soil layers and management measures should be optimized to reduce the effects of disasters on crops. In addi-tion to that, disaster index system should be reinforced in terms of establishment, monitoring, warning and prevention to lay scientific foundations and provide refer-ences for safe crop production and preventing and reducing disasters.展开更多

Operational experience gained by the collieries confirms that reducing methane release during longwall operations often requires decreasing operating speed of a shearer in a shift. The paper presents an analysis of the parameters and factors,which have critical influence on the formation of methane hazard in longwall areas with high production capacity.展开更多

But such fertilizers clearly pollute the plant and the yield. To eliminate such health hazards, an experiment was done by placing a plant inside an electromagnetic solenoid which has an arrangement to apply oscillatory magnetic field. It has been found that leafs are wilted due to loss of water from roots （since plucked from ground） exhibiting xanthophyl synthesis after about 60 minutes of oscillation. This phenomena clearly shows an increase in rate of ascent of the sap and hence the pulse rate. This action follows due to the resultant dominating effect of its diamagnetic water （90-95%）. Now, if the field is made stimulatory, the pulse rate becomes abrupt, which in turn increases the growth of the plant and its yields. Therefore, ifa farming-field is divided into several small sections with arrangements of applying stimulatory magnetic field, then the plant＇s growth becomes almost similar as found by use of fertilizers. Hence, the stimulatory magnetic field can take over the use of fertilizers in plant＇s growth, saving us not only from their health hazards but also from millions of rupees spent in their production.展开更多
