  close mowing
Close mowing reduces the aboveground dry weight and root dry weight of kikuyugrass, but is Mowing to Prevent Weed Colonization.
      
Close mowing of the orchard drive lanes during summer and fall will help to limit reproduction of weeds.
      
  low cut
We used a pulse train with randomised pulse locations and a band-limited noise with low cut-off frequency as input signals, and applied a cross-spectral measure to quantify their noise content.
      
We perform an estimate of the axion mass by including flavour instanton effects and show that, for low cut-offs, the axion is sufficiently massive to prevent it from being phenomenologically unacceptable.
      
This low cut-off frequency is related to a fast temporal adaptation of the on-off units to trains of short light pulses.
      
The use of high-pass filters having a low cut-off frequency, with gradual slopes of attenuation, and high cut-off frequency filters with a steep slope of attenuation, is advocated for phono-cardiography.
      
Our results suggest very low cut-offs for people or households to classify as definitely poor for some social indicators.

Rubber trees of RRIM600 clone tapped for three and six years were used as materials respectively, the present study gave a primary account on the difference of polyamine distribution between tapping and none--tapping panel, high tapping and low tapping cuts. Three kinds of polyamines, putrescine, spermidine and spermine, were found in the latex of rubber trees, among which putrescine was dominant. The contents of putrescine and total polyamines in tapping panel were higher than those in none--tapping panel....

Rubber trees of RRIM600 clone tapped for three and six years were used as materials respectively, the present study gave a primary account on the difference of polyamine distribution between tapping and none--tapping panel, high tapping and low tapping cuts. Three kinds of polyamines, putrescine, spermidine and spermine, were found in the latex of rubber trees, among which putrescine was dominant. The contents of putrescine and total polyamines in tapping panel were higher than those in none--tapping panel. The nearer the distance from the cut was, the higher level and more active biosynthesis of putrescine were. While in the none--tapping panel putrescine and other polyamines remain relatively stable. The contents of three kinds of polyamines in low tapping cuts which had been tapped for six years were all higher than those in high tapping cuts which were newly tapped. Therefore it was suggested that tapping could stimulate the biosynthesis of polyamines mainly putrescine.

分别以3割龄和6割龄RRIM600胶树为材料比较了多胺在割面与非割面、高割线与低割线上的分布差异,并讨论其与割胶的关系。胶乳中含有Put、Spd和 Spm 3种多胺,以Put含量为主。割面上的Put和总PAs含量高于非割面。割面上离割口越近Put含量越高,其生物合成越活跃;非割面上的Put及其它多胺垂直变化不大。低割线上的各类多胺含量均高于高割线。割胶促进排胶,也促进多胺的生物合成。

Tapping panel planning for upward tapping was studied. When rubber trees were tappable, i.e., the circumference of the trunk at 100 cm above the ground was about 50 cm, the circumference of basal stem was measured and divided into several parts (s/4, s/8). The annual tapping orders were arranged upwards from the basal stem. The basal panel was tapped upward with the acclivitous cut being 45°~50°Three years upward tapping experiments showed that the yield, DRC and other characters such as growth of rubber trees...

Tapping panel planning for upward tapping was studied. When rubber trees were tappable, i.e., the circumference of the trunk at 100 cm above the ground was about 50 cm, the circumference of basal stem was measured and divided into several parts (s/4, s/8). The annual tapping orders were arranged upwards from the basal stem. The basal panel was tapped upward with the acclivitous cut being 45°~50°Three years upward tapping experiments showed that the yield, DRC and other characters such as growth of rubber trees tapped upward on the s/4 of the basal panel were similar to those of the control tapped on s/2 of the trunk at 100 cm above the ground.

初步研究了由下往上的割面规划方法:当橡胶树茎干离地面100cm处的围径达到约50cm时,量取根颈处的围径,然后将该处围径等分为4个或8个割面(s/4、s/8),各个割面的割胶年序均由根颈处开始依次向上排列。该割面规划法的低割面采用阴刀割胶:在上倾45°~50°、割线面外斜的割线上用拉刀由下往上割胶。采用该法割胶3a的结果表明,低割面s/4↑的产量、干含和生长量等与对照(高100cm处s/2)相当。

It is summarize the study on inclined upward tapping of the rubber tree in the world. There are also the clear effect to increase the yield and the dry rubber content, reduce brown bark disease with the new method in Hekou farm . It is brought forward the advice to enlarge test in Yunnan.

综述了国内外橡胶树低割面阴刀割胶技术的研究结果.河口农场初试亦表明低割面阴刀割胶比常规割制有胶乳干含和产量提高、死皮明显降低的显著效果。
