摘  要：
【目的】通过喷施肥料效应田间试验,检验雌花盛花期喷施硼酸(B)、尿素(N)、糖(S)复合肥料对盛果期新温185号核桃坐果率的影响,为新疆南疆盆地新温185号核桃根外肥料的科学有效施用提供解决方案。【方法】采用"3414"喷施肥料效应田间试验和多元线性逐步回归分析。【结果】新温185号核桃坐果率的常用对数(log10q)与硼酸(B)、尿素(N)的喷施浓度及二者的交互作用(B×N)存在极显著的线性相关关系(P<0.01),且与硼酸、尿素的喷施浓度呈极显著正相关,与二者的交互作用(B×N)呈极显著负相关,即:log10q^=1.641 0+0.066 9B+0.047 3N-0.012 8B×N。糖(S)的喷施浓度与新温185号核桃坐果率常用对数的相关性不显著(P>0.05)。新温185号核桃雌花盛花期硼酸(含硼17.49%)的适宜喷施浓度为3.695 3 g/L,尿素(含氮46%)的适宜喷施浓度为5.226 6 g/L,理论坐果率期望值可达到77.31%。【结论】雌花盛花期喷施硼酸和尿素的复合肥料,可显著提高新疆南疆盆地盛果期新温185号核桃的坐果率。

摘  要：
【Objective】Through spraying fertilizer effect field trials,the experiment aims at testing the effect of spraying fertilizer,which was compounded by boric acid( B),urea( N) and sugar( S),at the full- bloom phase of pistillate flowers on the fruit setting rate of Juglans regia ‘Xinwen 185'in the prosperous fruit stage,with a view to providing a compound fertilizer formula which was used outside of the roots of J. regia‘Xinwen 185'in the Southern Xinjiang Basin.【Method】Both of the"3414"spraying fertilizer effect field trials and the multiple linear stepwise regression analysis were used.【Result】The common logarithm( log10q)of the fruit setting rate of J. regia ‘Xinwen 185'had highly significant linear correlation( P < 0. 01) to the effect of spraying concentration of boric acid( B),urea( N) and the interaction effect of them( B × N),and was highly significantly positively correlated to the effect of spraying concentration of boric acid and urea,was highly significantly negatively correlated to the interaction effect of them,but was not significantly correlated to the effect of sugar( P > 0. 05). The linear relationship was log10q^= 1. 641 0 + 0. 066 9B + 0. 047 3N- 0. 0128 B × N. The suitable spraying concentration of boric acid( 17. 49% of boron) was 3. 695 3 g /L and urea( 46% of nitrogen) was 5.226 6 g/L. The expected value of the theory fruit setting rate can reach 77.31%.【Conclusion】It was found that spraying compound fertilizer of boric acid and urea at the full-bloom phase of pistillate flowers of J. regia‘Xinwen 185'could increase the fruit setting rate significantly at the prosperous fruit stage in the Southern Xinjiang Basin.
