网纹甜瓜无土栽培生长动态观察

The Study on Growth Development of Muskmelons in Soilless culture

以土壤栽培为对照,观察了网纹甜瓜无土栽培条件下植株生长,果实膨大的变化。结果表明:无土栽培4月20日、5月5日株高、叶片数均显著高于对照,5月5日之前增加速度是对照的1.26倍、1.36倍,是5月20日至6月19日增加速度的10.9倍、8.9倍。无土栽培授粉后20、30、40 d果实纵径均显著高于对照,授粉前20 d纵径的增加速度是对照的1.29倍,而且前20 d果实纵、横径增加速度是后20 d的5.5倍和3.7倍。

The characters on vegetative growth and fruit development were observed in Soilless culture, with soil cultivation as CK. The results indicated, both plant height and leaf numbers on April 20^th, May 5^th were obviously higher than CK, their increased speeds before May 5^th were 1.26 times, 1.36 rims of CK, and 10. 9 times, 8. 9 times of that during May 20^th to June 19th. Moreover, fruit vertical diameter on 20 d,30 d,40 d after pollination were significantly higher than CK. Its increased speed during the early 20 d was 1.29 times of that CK. At the same time, the increased speeds at fruit vertical and transverse diameter during the early 20 d after pollination were 5.5 times, 3.7 times of that during the late 20 d.
