Growing vegetables in rockwool(RW) culture started several years ago in Japan. But appropriate method for deciding amount of nutrient solution has not been confirmed. In the present study, muskmelons were grown in RW to develop a system for applyin gnutrient solution based on the amount of integrated solar radiation.Experiments were conducted spring and fall in 1986, 1987 and 1988, respectively. Basically comparison was made between application of nutrient solution only in the morning and the application all day(sunrise through sunset). Effects of "reducing water treatment" and "RW slab thickness" on the growth were also combined to the comparison. The application was regulated with microcomputer. As the result, growth,fruit yield and external appearance were greater in application all day than the application in the morning, and in control than reducing water treatment. RW thickness affected the growth little, but thicker RW mat was somewhat better. Growing muskmelons in RW seems not to be necesarry to manage moisture content in mdeium the same management as done in soil culture like reducing water before and after pollination stage, and prior to harvest.The RW slab moisture content should be always maintained at constant. The relationship between moisture condition in plants and stage, timing and amount of the application should be studied more.

几年前在日本，洛克羊车（RW）文化种植蔬菜。但是尚未确认确定养分溶液量的合适方法。在本研究中，在RW中生长了Muskmelons，以基于综合太阳辐射的量开发用于申请的系统。分别在1986年，1987年和1988年进行了春季和秋季。基本上只有在早晨的养分溶液和整天应用（日出到日落）之间进行比较。还将“减少水处理”和“ RW平板厚度”对生长的影响进行了比较。用微型计算机调节该应用。结果，与早晨的应用相比，整天的生长，果实产量和外观的应用都要大于减少水处理。 RW厚度对生长的影响很小，但较厚的RW垫子稍好一些。在RW中生长的Muskmelons似乎并不是在Mdeium中管理水分含量与土壤培养中相同的管理，例如减少授粉前后的水分相同的管理。应该更多地研究植物中的水分状况与阶段，时机和应用的数量之间的关系。
