‘温185’核桃雌花盛花期喷施肥料的坐果率效应
- Title:
- Effect of Spraying Fertilizer at the Full-blossom Period of Female Flowers on the Fruit Setting Rate of Juglans regia ‘Wen185’

- 摘要:
- 以新疆南疆盆地核桃主栽品种‘温185’为研究对象，基于“3414”肥料效应田间试验方案，研究了在盛花期喷施N（尿素）、B（硼酸）、S（糖）为成分的复合肥料对其坐果率的效应，为‘温185’核桃盛花期的田间喷肥管理提供科学依据。结果表明：‘温185’核桃的坐果率（q%）q值以10为底的常用对数同S（糖）的喷施浓度相关性不显著（P＞0.05），与喷施N（尿素）、B（硼酸）的浓度以及二者的交互作用（N×B ）存在极显著（P＜0.01）的线性相关关系；雌花盛花期N（含氮46%）的喷施浓度小于5.928 6 g?L-1和B（含硼17.49%）的喷施浓度小于3.857 1 g?L-1时，对‘温185’核桃的坐果率存在正效应。在新疆南疆盆地核桃雌花盛花期喷施适量浓度的硼酸和尿素，有助于提高‘温185’核桃的坐果率。
- Abstract:
- Taking Juglans regia ‘Wen185’ as the research object in the Southern Xinjiang Basin,based on ‘3414’ spraying fertilizer effect field experiment,the effects of spraying compound fertilizer by N(urea),B(boric acid),and S(sugar)at the full-blossom period were tested to provide a scientific basis for spraying fertilizers management of J.regia ‘Wen185’.The results showed that the denary logarithm of fruit setting rate(q) of J.regia ‘Wen185’was not significantly correlated(P>0.05)with the spraying concentration of S(sugar),but it had a highly significant(P<0.01)linear correlation with the spraying concentration of N(urea)and B(boric acid)and interaction between them(B×N).There were positive effects on the fruit setting rate of J.regia ‘Wen185’ while the spraying concentration of N(46% of nitrogen)was less than 5.928 6 g?L-1 and the spraying concentration of B(17.49% of boron)was less than 3.857 1 g?L-1 at the full-blossom period of female flowers.In the Southern Xinjiang Basin at the full-blossom period of female flowers,sprayed suitable concentration of B and N could increase the fruit setting rate of J.regia ‘Wen185’.
