And from the cultural test results,we know that in Longyan area,sowing on April 4th, 12cm plant spacing,3 grain seeds per hole and applying 45kg/hm~2 N are the most cooperative cultural techniques for "Tainan 13".
while transplanting, it is better to apply mixed fertilizer with 6.0kg/m2, and the appropriate row spacing is 25cm, plant spacing is 15-20cm, the shading light should be 65% in the first year after transplanting. To gain good quality and high output, crude drugs of Mount Tai sealwort should be harvesting three years after transplanting, its output of dry product is up to 4410kg/hm2.
9.Therefore in Jinzhong region the optimal production pattern of chicory was: sowing on 5th , June, then transplanting, the row and plant spacing was 20cm × 15cm, fertilizing during postponing seedling stage , after controlling seedling and before full crop, harvesting taproots before light frost, and applying the blanching of sand culture.
In order to get high and stable yield for the two interplanting crops, the seed spacing should be 29.6 cm and the large row spacing should surpass 90 cm to aviod overlap of the condensed space intervals of maize leaf areas.
By experiment and applying the theory of motion the effect of the seed-dropping direction of a precision drill on its seed spacing uniformity Was analysed and the advantages of dropping the seeds across was pointed out.
On the forest land returned from the cultivated land,its suitable cultivated distance of plantlets and rows is from 0.8m×1.5m to 0.6m×1.5m and its suitable cultivated density is 8325～11100 plantlets/hm~2 while on the barren hill side and uncultivated land ,they are 0.6m×2m and 8325 plantlets/hm~2 respectively.
The high-yielding techniques of rice intensified culture were put forward as follows:seedling age being 10~15 days, planting size being 25cm×25cm, applying 225kg/hm~2 pure nitrogen, the ratio of basic fertilizer, seedling fertilizer, jointing fertilizer and flowering fertilizer being 3∶3∶2∶2.
Effects of plant spacing and interplanting with oilseed rape on colonisation of dwarf hops by the damson-hop aphid, Phorodon hum
Plant spacing was examined for its affect on stool weight variability.
The effect of pollinator activity on gene flow in colonies of Viola were examined by measuring pollinator flight distances, the frequency of interplant flights and percent pollination under different plant spacing patterns.
To the extent that plant spacing and morphology is correlated with pollinator visits and ultimate seed set, Hylemya could be choosing flowers optimally, and playing a role in the evolution of floral traits.
Growing season performance was apparently affected by plant spacing, suggesting that competition for spatially distributed resources occurs.
In nature, the swarms exhibit elements of inner integration, such as homogeneous age structure, collective behaviour, and relative constancy of inter-individual spacing.
No differences were apparent after a 24-day separation.5.Individual recognition by olfactory cues may help this solitary species maintain individual spacing and reduce aggression among potential mates.
This paper investigates the determinants of individual spacing behaviour in a desert baboon population (Papio cynocephalus ursinus).
The individual spacing in a monkey troop varies with species.
Specifically, we analyzed how the worker bees in the mantle of a swarm cluster adjust their body orientation, wing spread, and inter-individual spacing to form a protective curtain when wetted.
