专用缓释肥对辣椒生物性状、品质及产量的影响

Effects of Special Slow-release Fertilizers on the Biological Traits,Quality and Yield of Pepper

为探明专用缓释肥在生产上的应用效果,采用盆栽试验研究自制非包膜型辣椒专用缓释肥对辣椒长势、品质和产量的影响。结果表明:施肥后辣椒植株生长状况得到显著改善,主要表现:1)叶面积。各处理间差异显著,总体以专用缓释肥最大。2)叶绿素含量。专用缓释肥显著提高辣椒叶片叶绿素含量,施用专用缓释肥的2个辣椒品种叶绿素总量较其专用复合肥的增长20.22%和10.44%,比商品缓释肥的提高23.93%和5.01%。3)根系。专用缓释肥总体上有效改善了根系生长状况,能增加果实VC和氨基酸含量,果实硝酸盐含量明显低于非缓释肥处理。专用缓释肥显著提高辣椒产量,2个辣椒品种的产量较普通复合肥的增产29.99%和17.06%,较商品缓释肥的增产17.46%和12.04%。

To explore the application effects of special slow-release fertilizer in production,a pot experiment was carried out to investigate the effect of special slow-release fertilizer for vegetables on the growth,quality and yield of pepper.The results showed that the slow-release fertilizer could obviously improve the growth of pepper. This advantage is mainly reflected in three aspects. 1 ） Leaf area. Significant differences were found between groups,mainly with the treatment of PSRF the highest.2） Chlorophyll content.Chlorophyll content of two varieties of pepper in QSRF increased by 20.22% and 10.44% compared with common compound fertilizer for pepper （PCF）,and increased by 23.93% and 5. 01% compared with commercial slow-release fertilizer （MSRF）in the pot experiments.3）Root system. QSRF applications in the pot experiments were found effectively improved the root growth conditions of two species of pepper besides on the average root diameter and root volume （Yujiao 5）.Content of vitamin C and amino acid were increased by QSRF.Content of nitrate was decreased by QSRF compared with no-slow-released fertilizers.At last for the yield of both of the two kinds of pepper in QSRF increased by 29.99% and 17.06% compared with compound fertilizer （OCF）,and increased by 17.46% and 12.04%compared with commercial slow-release fertilizer （MSRF）.
