不同苗龄分苗对辣椒植株素质及产量的影响

Effects of Reculturing Seedlings at Different Seedling Ages on Plant Quality and Yield in Red Pepper

用不同苗龄的辣椒幼苗分苗移栽营养土进行培苗试验研究,对辣椒的株高、茎粗、开展度、单株挂果和小区产量的多项分析比较。结果表明:四叶龄分苗成绩最好,六叶次之,两者均优于滑苗对照处理和直接营养块育苗。分苗过早的二叶二心和二叶处理的成绩较差。试验证明,在辣椒生产中适时分苗于营养土培苗后移栽大田,能取得较好的生产效果。

The pepper seedlings at different seedling ages were transplanted in the nutritive soil for reculturing seedlings to study the effect of recultured seedlings at different seedling ages on plant height, stem diameter, spreading degree, fruits/ plant and yield/plot. The results indicated that the plant quality and yield of recultured seedlings at four-leaf age and six-leaf age all were higher than those of CK and directly culturing seedlings in nutritive lump, which showed that the recultured pepper seedlings at the suitable leaf age could obtain the better economic benefit in red pepper production.
