0.02%二氢卟吩铁在朝天椒上的应用效果

为了探究植物生长调节剂0.02%二氢卟吩铁可溶粉剂对朝天椒生长和产量的影响，设置0.02%二氢卟吩铁可溶粉剂3 000、4 000、5 000、6 000倍液4个处理，以清水处理为对照，分别在朝天椒主要生长节点施药4次，并调查朝天椒的生长和产量指标。结果表明：相比对照，不同浓度处理对朝天椒生长及产量均有一定的影响；其中，以T₁(0.02%二氢卟吩铁可溶粉剂3 000倍液)、T₃(0.02%二氢卟吩铁可溶粉剂5 000倍液)处理对朝天椒的株高、茎粗、分枝数影响较大，其次为T₂处理(0.02%二氢卟吩铁可溶粉剂4 000倍液)，3个处理均分别与对照差异显著；以T₂、T₃处理对朝天椒的叶面积、叶周长、叶长、叶宽、SPAD值的影响较大，且显著高于T₄处理(叶周长除外)和对照；以T₂处理对朝天椒单果鲜质量影响最大，与T₁和T₃差异均不显著，但显著高于T₄处理和对照；以T_...

The Application Effects of 0.02% Iron Chlorin on the Capsicum frutescens

Abstract: In order to explore the effect of 0.02% iron chlorin soluble powder (a plant growth regulator) on growth and yield of Capsicum frutescens, four treatments of 0.02% iron chlorin soluble powder 3 000, 4 000, 5 000 and 6 000 times solution were set up, and water treatment was used as the control. The main growth nodes of Capsicum frutescens were sprayed four times, and the indexes of the growth and yield of Capsicum frutescens were investigated. The results showed that compared with the control, the growth and yield of Capsicum frutescens were affected by different concentrations, among them, T1 (0.02% iron chlorin soluble powder 3 000 times solution), T3 (0.02% iron chlorin soluble powder 5 000 times solution) treatments had a greater impact on the plant height, stem diameter, branch number of Capsicum frutescens, followed by T2 treatment (0.02% iron chlorin soluble powder 4 000 times solution), the three treatments were significantly different from the control, respectively. The effects of T2 and T3 treatment on leaf area, leaf perimeter, leaf length, leaf width, SPAD value of Capsicum frutescens were greater than those of T4 treatment (except for leaf perimeter) and control. T2 treatment had the greatest impact on the fresh weight of single fruit of Capsicum frutescens, which was not significantly different from T1 and T3, but significantly higher than T4 treatment and control. The T3 treatment had the best effect of increasing yield with fresh pepper increasing by 19.74% and dry pepper increasing by 47.01% compared to the control. Moreover, the T3 treatment had no significant difference compared to T1 and T2 treatments, but was significantly higher than T4 treatment and the control. It was recommended to use 0.02% iron chlorin soluble powder 5 000 times solution in production.
