Both burying calcium carbide and injecting acetylene gas within the rubber root Zone are highly effective stimulating methods without bark injury due to trunk application. For puncture tapping, burial of calcium carbide gave a greater yield increase and better diluting effect than bark application of ethrel. The optimal dose of calcium carbide for mature buddings was found to be 10-15 grams/tree every 15-20days. With acetylene or ethylene applied to the tree base, the closer the puncture point is to the stimulate...

Both burying calcium carbide and injecting acetylene gas within the rubber root Zone are highly effective stimulating methods without bark injury due to trunk application. For puncture tapping, burial of calcium carbide gave a greater yield increase and better diluting effect than bark application of ethrel. The optimal dose of calcium carbide for mature buddings was found to be 10-15 grams/tree every 15-20days. With acetylene or ethylene applied to the tree base, the closer the puncture point is to the stimulate zone, the higher is the yield and also the higher is the latex pH, thus resulting in a regular gradient variation. Based on the difference in yield of puncture points at various distances from the stimulated zone, the trunk of the tree is rated as highly effected parts, slightly effected parts and trace-gas diffusing parts. Acetylene and ethylene have no obvious effect on girth inerement of immature trees.

在股树根系范围内埋施电石或充乙炔气体是避免树干施药防害树皮的高效刺激方法。对针刺采胶而言,埋施电石比涂施乙烯利增产效果更显著,稀释效应更强烈。成龄芽接树的电石施用量以每15~20天埋施10~15克为宜。胶树基部施用乙炔或乙烯后,距离施药部位越近的针孔,产量越高,胶乳pH越偏碱,形成有规律的梯度变化。根据施药后树干各部位针孔产量的差别,分为高效区、低效区和气体微量扩散区。这两种气体对不果胶的幼树树围生长无明显的影响。

Based on the crust structure in China and its vicinity areas, especially background of deep crust structure where some large earthquakes took place in recent years, this paper discusses the possible structure model for the occurrence of earthquakes.The results show that all modern seismicity occurred in the places where the thickness of crust changed rapidly or the structure twisted; Moreover, in these areas shocks would exist on the slopes or fringes of lifting parts of top upper mantle and other lifting areas nearly. In these spots the stress easily accumulates and breaks take place frequently.This is the deep structure background of occurrence of earthquakes Furthermore, the areas where deep earthquakes take place are closely related to the high gradient variation of gravity field, magnetic field, and to low resistance layers, low and high velocity layers.This kind of relation between earthquakes and deep geological structure as well as features of geophysical fields must be envisaged in the earthquakes prediction and in searching for their origin.

本文根据我国境内及邻近地区地壳结构的分布特征,特别是近年来我国发生的几个大地震所处的深部地壳构造背景,讨论了地震孕育与发生的可能构造模式。结果表明,近代地震活动地带均为地壳厚度急剧变化的地带和地壳构造的转折交汇部位。在深部构造上又为上地幔顶部局部的隆起地区及邻近隆起地带的边缘或斜坡上。此外,地震发生的深部部位与重力场、磁力场的高梯度变化以及地壳中的低电阻层、低速层和高速层的分布密切相关。这种与地震有关的深部构造背景与地球物理场特征,是今后地震预报和地震成因研究必须十分重视的。
