Transmittance in the intercropping system , different spacing of leaf area index ( LAI ) are expressed as with the apricot phenology ( flowering to fruit maturity ) goes upward trend , to fruit maturity , decreased slightly .

选用40～80cm高的苗木，株行距规格可为4m×4m，在抚育期内应注意清除藻类及残次林木等。

The seedlings should be 40 - 80 cm high , and the space of plantation should be 4 m x 4 m. During the tending period , alga and unnecessary woods should be cleared away .

选择株行距为3.5m×15m的枣豆间作田，研究其光照和土壤水分空间变化及其对大豆生长发育的影响。

The effects of variations of light intensity and soil water content on soybean growth and development was carried out in jujube-soybean intercropping system , in which tree row spacings were 3.5 m × 15 m.

据此阐明目前生产上广泛采用67～70cm的垄作，已超过大豆的有效株行距，造成了土壤资源等的浪费。

In the present production , the ridge width usually was 67 ~ 70cm , and longer than effective row width of soybean , which would waste soil resources .

不同密度有其适宜的株行距配置，在60.0万株/hm2密度下，20cm行距较30,40cm行距有利于优化大豆群体结构，实现高产。

Different density has its fitting row spacing . Under the density of 60.0 × 104 plants per ha , row spacing ( 20 cm ) vails group structure is superior to row spacing ( 30 cm , 40 cm ), which is conductive to achieving high yield .

这通常意味着要比正常生产性苗圃的同样树种采用较大的株行距。

This usually means a wider spacing than would be used in an ordinary commercial nursery for the same species .

研究表明，该地区防护林建设应适当减小株行距，避免害虫特别是天牛易感树种的单一配置。

The results indicate that the space of the plants should be reduced and the single arrangement of the susceptible species should be discarded .

由于种子园母树株行距大，光照充足，适于喜光性虫种的生存繁殖；

Growing Good Corn Because of the large space between seed trees and the plentifulness of light , the phototactic insects are favoured in existence and propagation .

核（桃）农间作系统中作物与核桃树的距离越近，产量越低，并且核桃树株行距越小，变化趋势越明显。

The closer from the walnut trees , the lower the crop yield in walnut-crop intercropping system . And the smaller planting spacing for the walnut trees , the more obvious change trend .

随着杏树株行距的减小，树高的增加和冠幅的扩张，杏与粮棉间作系统间作物光合有效辐射时空窗逐渐减小直至消失。

With the decrease of the apricot planting spacing , tree height increase and crown width expansion , apricot-wheat & apricot-cotton intercrops of intercropping systems " PAR space-time Windows " reduce gradually until vanishing .

人工林在造林初期通常是由造林株行距所确定的均匀分布，随着林木分化和自然稀疏过程的发生，林分将逐渐由均匀分布向随机分布或聚集分布发展。

In the early , plantation is usually uniform distribution by the planting . In the process of the differentiation of tree and self thinning , it is developing to the aggregate from the uniform of the spatial distribution .

研究提出作物有效营养面积新概念，并建立了大豆植株个体营养面积与产量关系模型，优化解析出大豆有效营养面积为2837.5cm2，即有效株行距为53.3cm；
