以‘陇椒5号’辣椒为试验材料,不施肥(CK)和普通施肥(CK1)为对照,通过盆栽方式,研究“”一次性基施“”不同缓释期高氮控释肥和“”一基多追“”普通化肥的施肥方式对辣椒生长、干物质积累以及不同器官干物质分配的影响,以期为辣椒栽培中合理使用控释肥提供理论依据。结果表明,与CK相比,施肥可显著提高辣椒株高、茎粗、叶面积的增长以及干物质的积累,促进辣椒地上部干物质积累,增强根系活力。辣椒移栽120天内,“一次性基施”控释肥的辣椒植株干物质积累量较“一基多追”普通化肥低19.3%~30.5%、干物质积累速率低20.8%~33.5%;移栽120天后,干物质积累量较“一基多追”普通化肥高3.9%~15.5%、干物质积累速率高60.9%~63.6%;干物质最大积累速率出现的时间滞后26~29天;“一次性基施”控释肥使根的干物质分配较“一基多追”普通化肥低8.3%~11.1%,叶片干物质分配较“一基多追”普通化肥高7.0%~7.2%。说明“一次性基施”控释肥有利于生育后期辣椒的生长。
The experiment was conducted in pot experiment with “Longjiao 5” pepper as test material, without fertilization (CK) and common fertilization (CK1) The effects of fertilizer application mode on the growth of peppers, accumulation of dry matter and distribution of dry matter in different organs were studied in order to provide a theoretical basis for the rational use of controlled release fertilizer in pepper cultivation. The results showed that, compared with CK, fertilization could significantly increase the plant height, stem diameter, leaf area and dry matter accumulation of pepper, increase dry matter accumulation and increase root activity. Within 120 days after pepper transplanting, the dry matter accumulation of pepper plants with “one-time basal application” controlled release fertilizer was 19.3% -30.5% lower than that of “one quilts chasing”, and the dry matter accumulation rate was 20.8% 33.5%. After 120 days of transplanting, the accumulation of dry matter was 3.9% -15.5% higher than that of common fertilizers, and the accumulation rate of dry matter was 60.9% -63.6%. The time lag of the maximum accumulation rate of dry matter 26 to 29 days; “one-time base facilities ” controlled release fertilizer to make the distribution of dry matter more than “a base to chase ” ordinary fertilizer low 8.3% ~ 11.1%, leaf dry matter distribution more Chase “ordinary fertilizer high 7.0% ~ 7.2%. Description ”one-time base facilities " controlled release fertilizer is conducive to the growth of late peppers.
