不同密度和再生方式对嫁接茄子产量的影响

Effects of Different Densities and Regenerative Methods on Grafted Eggplant Yield

为了进一步揭示再生对茄子产量的影响,试验以嫁接茄子为试材,采用三种密度(4.1万株/hm^2、4.8万株/hm^2、5.5万株/hm^2),三种再生方式(长截、中截和短截),日光温室吊绳栽培,探讨不同再生方式、密度对产量的影响。研究结果表明:适当密植配合短截再生使茄子根系和茎生长增强,增加了水分和矿质元素的吸收和在植株体内的运输,从而使产量增加。

Effects of different regenerative methods and densities on grafted eggplant yield were studied in three plant densities （41000plants/hm^2, 4 lants/hm^2 and 55000plants/hm^2） and three regenerative methods （short pruning, middle pruning and long pruning） in greenhouse. The results indicated that there was vigorous root and stem growth in proper density with short pruning treatment, which accelerated transportation of water and mineral element in plant. These resulted in higher yield of eggplant.
