不同育苗方法对辣椒幼苗生长性能的影响

以贵州朝天椒遵椒2号为材料,研究露地撒播、露地营养块、不同基质配方漂浮育苗等方法对辣椒幼苗生长性能的影响。研究结果表明,漂浮育苗对缩短辣椒出苗时间、提高出苗率、提高幼苗的生长能力等均具有良好作用,其中以粉碎腐熟的玉米秸秆+蛭石处理的基质效果最佳,辣椒出苗率达到94.3%,播种50,60,75 d后株高分别达8.49,17.05,29.28 cm,茎粗分别达0.161,0.226,0.313 cm,主根长度13.38 cm,须根长度12.43 cm。

Effects of Different Seedling-raising Methods on Growth Performance of Hot Pepper Seedlings

This paper studied the effects of different seedling-raising methods on the growth performance of Zunjiao No.2 （Capsicum fmtescens var.）, and the methods were broadcast seeding in open field, seeding on nutrition block in open field and floating seeding with different substrates. The results showed that the floating seeding method was beneficial to shorten the germination time and increase the seed vigor of hot pepper, and improve the growth ability of seedlings. And the best culture substrate was the grinding decomposed corn straw＋vermiculite, the germination rate of which reached 94.3%, and the plant height were 8.49 cm, 17.05 cm and 29.28 cm, while the stem diameter reached 0.161 cm, 0.226 cm and 0.313 cm respectively after sowing 50, 60 and 75 days, with the length of the main root reaching 13.38 cm and the distribution length of fibrous root reaching 12.43 cm.
