Research on the effect of straw mulching on the soil moisture by field experiment in the piedmont plain of the Taihang Mountains
Straw mulching Soil moisture Soil water content Deep layer Soil moisture conservation
2018/3/23
To reveal the influencing effect of the long-term straw mulching on the soil moisture, this paper employed the field experiment data in 2010 of a typical area of Taihang Mountains plain, observed the ...
Methodology of processing the results of field experiment monitoring of the technological procedure of sowing
coulter trajectory acceleration amplitude curve Fourier transform
2016/4/5
The non-uniformity of distribution of seeds sown in a row influences their productivity. To analyse and eliminate the
causes of non-uniformities, the straight motion of coulters must be separated fr...
Modifying the elastomechanics of the stem and the crown needle mass distribution to affect the diameter increment distribution: A field experiment on 20-year old Abies grandis trees
Abies grandis elastomechanics field experiment stress strain diameter increment distribution
2015/2/2
In the spring of 2000, field experiments were begun on three 20-year old grand fir (Abies grandis) to influence the elasto-mechanical behavior of the stem, as well as the distribution of the assimilat...

2009/9/10
Medaka (Oryzias latipes) populations have recently declined to such a level that they are listed as a species in danger of extinction in the Red Data Book. And a decline in the numbers of catfish and ...
A Basic Study on Field Experiment and Investigation Methods in Rice Plant:III. Precision of some sampling methods in sample survey of quantitative characters
Coefficient of variation Field experiment Quantitative character Rice plant Sampling method
2009/8/5
In sample survey on field experiment, samples have to be sampled at random in principle, but samples are often taken systematically due to restriction of time, labor and plot area. In order to get inf...
