planting
The influence of woodland soil bulk density on the growth and distribution of fine root system of main planting tree species in the Weibei Loess Plateau was investigated by means of pot culture and field survey.
      
Besides, runoff and sediment produced in mixed planting of apple trees and crops were 16.14-fold and 2.96-fold than those of O.
      
Container stecklings are more likely to increase the planting survival rate.
      
Therefore, it is important to consider planting densities on the hillsides with slope gradients less than 10° for reconstructing vegetation.
      
To improve soil quality and maintain sustainable productivity, some measures, including planting mixed conifer with hardwood, preserving residues after harvest, and adopting scientific site preparation, should be taken.
      
ascendens is suitable for planting in conditions of root submersion or water-saturated soil.
      
Long-term effect of different planting proportions on forest landscape in Great Xing'an Mountains, Northeast China after the cat
      
A landscape model (LANDIS) was used to study the long-term forest dynamics under five planting types (100% larch (P1); 70% larch and 30% Mongolian Scotch pine (Pinus sylvestris var.
      
Results showed that different planting types had a significant influence on the abundance of larch, Mongolian Scotch pine and white birch.
      
The abundance of larch and Mongolian Scotch pine under these planting scenarios was higher than that under natural regeneration.
      
Under these planting scenarios, the abundance of larch increased with the increasing proportion of larch, and the abundance of Mongolian Scotch pine was in a similar way.
      
Contrary to larch and Mongolian Scotch pine, white birch had higher abundance under natural regeneration than that under these planting scenarios.
      
principis-rupprechtii artificial forest was about 2600 trees/hm2, which is also the reasonable planting density if the utilization of double cutting is not considered.
      
Meanwhile, in the third year, two quadrates (1×1 m for each) were set up in a crust-absent area and two different experiments of the asexual reproduction (broadcast planting and offshoots) were conducted, respectively.
      
The removal efficiency of four different sets of beds, namely the reed bed, the Zizania caduciflor bed, the mixing planting bed, and the control bed were studied.
      
Mechanical and sorption properties of starch-, PVA-, and peat-based composites for fabricating planting containers are studied.
      
It is suggested to use the same method for obtaining planting material during bottom rearing of Gelidium in the sea as that for intensive culture in tanks.
      
palmata, which were formed in the culture as in nature, function as growth cells facilitating growth of thalli in thick and natural "planting material" formed upon thalli fragmenting after their freezing in the winter season.
      
It was suggested that pretreatment of rocket seeds before planting with 20 Gy dose of γ-irradiation, may oppose the harsh effect of NO3 accumulation and increased the quality and quantity of rocket yield.
      
Planting pleistophytes in watercourses and biological ponds, into which pretreated wastewater is discharged, is especially efficient in summer and autumn, when the load on treatment facilities increases.
