- 摘要:
- 以“宁杞五号”红枸杞为试材，采用2因素3水平双向随机区组设计方法，进行喷施尿素、磷酸二氢钾不同浓度混合水溶液田间试验,分析不同浓度组合的叶面肥对枸杞树的生长及产量的影响，以期为枸杞叶面配方施肥及高效生产提供参考依据。结果表明：1）配施尿素和磷酸二氢钾的混合溶液对“宁杞五号”红枸杞的生长指标和产量提高的促进作用比单施尿素或者磷酸二氢钾的效果要好。2）尿素的浓度为3 g?L-1基，磷酸二氢钾浓度为1 g?L-1基基混合配施的效果最好，其对枸杞树新梢径粗、新梢长、冠幅以及产量的影响最大。3）通过交互作用分析，尿素用量为2.527 g?L-1基，磷酸二氢钾用量为1.593 g?L-1基，即二者比例为1∶0.630时，新梢径粗生长量达到理论最大值，最高增量为1.744 mm；尿素用量为2.593 g?L-1基，磷酸二氢钾用量为1.612 g?L-1基，即二者比例为1∶0.622时，新梢长生长量达到理论最大值，最高增量为48.479 cm；尿素用量为2.641 g?L-1基，磷酸二氢钾用量为1.665 g?L-1基，即二者比例为1∶0.630时，冠幅增量达到理论最大值，最高增量为23.955 cm基；尿素用量为2.825 g?L-1基，磷酸二氢钾用量为1.451 g?L-1基，即二者比例为1∶0.514基时，枸杞产量达到理论最大值，最高产量为12.830 kg。尿素和磷酸二氢钾的配施能够显著促进枸杞树木的生长和产量，在一定浓度的肥料用量范围内，枸杞新梢径粗、新梢长、冠幅、产量4项指标的生物累积量随浓度的逐渐增大，呈先增大后减小的趋势。
- Abstract:
- In order to analyze the effects of different combinations of foliar fertilizers on the growth and yield of wolfberry trees，‘Ningqi No.5’ red wolfberry was used as the test material,and a two-factor three-level two-way random block design method was used to spray urea and phosphoric acid.Field trials of mixed aqueous solutions of different concentrations of urea and potassium dihydrogen phosphate.This study can provide a reference for the leaf fertilization and efficient production of wolfberry.The results showed that,1)The mixed solution of urea and potassium dihydrogen phosphate had better effects on the growth index and yield increase of ‘Ningqi No.5’ red wolfberry than the effect of urea or potassium dihydrogen phosphate alone.2)The concentration of urea was 3 g?L-1基基，and the concentration of potassium dihydrogen phosphate was 1 g?L-1基.The best effect was the mixed application,which had the most significant effects on the new diameter,the new length,the crown width and the yield of the wolfberry tree.3)Through the interaction analysis,the amount of urea was 2.527 g?L-1基,and the amount of potassium dihydrogen phosphate was 1.591 g?L-1基,when the ratio of the two was 1∶0.630,the crude growth of the new diameter reached the theoretical maximum,and the highest increase was 1.744 mm;the dosage of urea was 2.591 g?L-1基 and the dosage of potassium dihydrogen phosphate was 1.612 g?L-1基,when the ratio of the two was 1∶0.622,the new slightly longer growth amount reached the theoretical maximum,and the highest increase was 48.479 cm;urea the dosage was 2.641 g?L-1基基,and the amount of potassium dihydrogen phosphate was 1.665 g?L-1基,when the ratio of the two was 1∶0.630,the crown width increment reached the theoretical maximum,and the highest increment was 23.955 cm;the urea dosage was 2.825 g?L-1基,the amount of potassium dihydrogen phosphate was 1.451 g?L-1基,when the ratio of the two was 1∶0.514,the yield of wolfberry reached the theoretical maximum,and the highest yield was 12.830 kg.The combined application of urea and potassium dihydrogen phosphate can significantly promote the growth and yield of wolfberry trees.Within a certain concentration of fertilizer use,the biological increase of the four indexes of wolfberry new diameter was larger,the new length was longer,the crown width,and the yield increase.The gradual increase in concentration showed a trend of increasing first and then decreasing.
