钾肥对幼龄骏枣果实内在品质的影响
Effects of Potassium on the Junzao Fruit Quality in Close-planting Garden
摘要
Abstract
[ObjectiveJThe purpose of this research aimed to explore the influence that different periods and amounts of potassium on the fruit quality of Junzao and find the optimum fertilization scheme to provide corresponding fertilization guidance for the development of Xinjiang jujube industry. [ Method ] Test on biennial wide - narrow close planting Junzao under different fertilizing amounts and different periods of potash fertilizer was carried out and the inner quality of Junzao fruit in different period was measured. [ Result] By increasing of potassium fertilizer, Junzao fruit nutrient levels were increased on the whole, and different fertilization amounts of potassium test found that 30 kg / 667 m2 K application increased the protein, cellulose, starch and VC content of Junzao fruit and increased the ratio of sugar and acid. It is the optimum application amount during the same period of potash fertilizer. And different fertilization period of potassium test also found that applying fertilizer in expansion period of Junzao fruit was effective, except for starch content below fruit core - hardening stage of potash fertilizer of Junzao,and protein,cellulose,vitamin content and the ratio of sugar and acids were higher than those of other treatments, and in the respects of protein and the ratio of sugar and acid compared to other treatments and the contrast, the difference was significant, so expansion period is the optimum fertilization period under the same amount of fertilizer. [ Conclusion ] Applying 30 kg/667 m potash in expansion period of junzao is the optimum fertilization scheme.关键词
