| 1. | A relationship exists between tree density and fruit yields .
植株密度和果实产量之间存在一种相关关系。 |
| 2. | Uniform normal plant population of 1 . 35 million plants / ha was used for late rice
晚稻一致采用正常植株密度135万株/公顷。 |
| 3. | The effect of plant density on the yield of rice for three varieties has been studied ( table 3 . )
已研究了三个水稻品种植株密度对产量的影响（表3 ） 。 |
| 4. | Plant population subsequently declined to less than 150 plants per sq . m . at about 65 mm planting depth
当播种深度为65毫米时，植株密度相应下降到150株/平方米。 |
| 5. | But the activity of roots of per plant was lowed by scc excluding the activity of roots of all plant per area was raised
对植株密度、生物量、叶绿素含量及根系活力均有明显提高。 |
| 6. | Plant density is an important factor for cultural management , there is a close relationship between plant density and fertilizer application
植株密度是栽培措施的重要因素，植株密度和施肥间存在密切关系。 |
| 7. | The experiment design included 2 levels nitrogen , 3 levels potassium with or without silicon application , and 2 plant densities , totally being 10 treatments with 3 replications
试验设计包括2个氮水平、 3个钾水平，施或不施硅肥、 2个植株密度，总共10个处理，三次重复（表2 ） 。 |
| 8. | An optimum planting density must be employed to get a high yield , depending upon soil condition , varietal tillering ability , fertilizer level , number of plants per hill , and planting season
获得高产必须采用最适植株密度，视土壤条件、品种分蘖力、肥力水平、每蔸苗数和播种季节而定。 |
| 9. | There was some increase in percentage of dead seedlings and non - earbearing plants and some decrease in 1000 grains weight and grains of single - ear along with the increase of the plant densities , but yields still increased because of the more increase in numbers of available ears
植株密度增加的同时，死株、无穗株百分数会增多，千粒重和单穗籽粒数会降低，但产量会增加，因为增加了有效穗数。 |
| 10. | Field experiments were conducted at shaoxing and fuyang , zhejiang province , using split - split plot design on early rice and split plot design on late rice respectively , to identify the roles of variety , fertilizer and plant population in achieving higher yield
早稻采用裂区-裂区试验设计和晚稻采用裂区试验设计的大田试验在浙江省绍兴和富阳进行，以检验品种、肥料和植株密度在取得高产中的作用。 |
