| 摘要: |
| 对现代温室无土栽培的水果型小黄瓜进行了两年4茬的产量测定。结果表明，不同年份和季节，黄瓜产量变化趋势基本一致，但年度总产量相差很大。正常情况下，秋冬茬始采期在定植后的30 d，产量高峰在定植后的50多天，春夏茬始采期在定植后的45 d左右，产量高峰在定植后的60～70 d，而且峰值高，高产期持续时间长，年度产量的60%以上在春夏茬。不同品种的产量变化趋势基本一致，但总产量和适宜生长季节不同。deltastar适合于春、夏、秋季种植，condesa冬季生长旺盛，适合温室越冬栽培。Printo抗逆性强，任何季节均可种植。正常年份，产量与温度在冬季呈显著正相关，在夏季呈负相关。产量与湿度在不同年份、不同季节表现不一。产量与光照时数均呈正相关，暖冬极显著，寒冬和夏季不显著。温度与湿度在秋冬茬呈极显著负相关，在春夏茬呈正相关。温度与光照在春夏茬呈极显著正相关，在秋冬茬相关不显著。湿度与光照多数呈不显著负相关。 |

| An analysis of cucumber yield laws and environmental factors in modern greenhouse |
|
|
| Abstract: |
| Some yield laws are concluded from the fruit-type,little-size cucumber siolessly cultivated in modern greenhouse during a two-year and four-rotation period.It shows that in different years and seasons and for different varieties,the altering trend of cucumber yield is nearly the same.However,the total yield of a whole year varies greatly.Under normal conditions,the earliest picking of spring-summer rotation comes about 45 days after field setting,and the peak yield comes 60 to 70 days after field setting.Also,its peak yield period lasts long.The yield in spring-summer makes up more than 60% of the gross produce of a year.The altering trend about yield of various varieties is basicly the same,but the total produce and suitable growing seasons are different.It's good for deltastar to be planted during spring,summer and autumn.While condesa grows well during winter time and is suited to be planted in greenhouse during winter time.Printo shows strong seress resistance and can be planted in any seasons.In normal years,produce and temperature are positively correlative in winter,and the correlation reaches notable level.Yet,they are negatively correlative in summer.The relationship between yield and humidity varies according to different years and seasons.Yield and sunshine hours are always positively correlative to each other.The correlation is extremely notable in warm winters,while not notable in cold winters and summers.Temperature and humidity are in extremely notable negative correlation in autumn and winter,while they are positively correlative in spring and summer.Temperature and sunshine hours are in extremely notable positive correlation in spring and summer,and the correlation is not notable in autumn and winter.In most cases,humidity and sunshine are negatively correlative. |
