叶面施肥对提高库尔勒香梨抗寒相关性的研究
Correlative Study of Foliage Fertilization on Korla Fragrant Pears for Improving Cold Resistance
摘要
Abstract
[Objective]The purpose of these experiments on foliar fertilization on Korla fragrant pears is to study the cold hardiness correlation. [ Method ] Through the phosphorus acid, nitrogen and boron of six different concentrations treatment 3 times, the cold resistance index of unripe branches was determined under artificial cryogenic stress conditions. [Result] The founding is that very significant differences exist between different treatments, among which PK2, N1, and N2 processing, cold control effect is good, and every index is higher. From the analyses of the whole indexes, a fat deal with high concentrations has better effect than the low concentrations of the fertilizers. Processing with boron fertilizer had no obvious treatment effect. [ Conclusion]The concentration of 0. 3% of the phosphorus acid and 0. 2% , 0. 3% of the nitrogen treatment effect is good, among which 0. 3% concentration of phosphorus has the highest cold resistance effect of the three indexes. It is significantly higher than the controls. Each index at the common - 281 shows no significant difference. Boron fertilizer can not be used for foliar fertilization on Korla Fragrant Pears to improve the cold resistance.关键词
