摘要
选用9 a生盛果期矮化密植梨枣树为试验材料,研究乙酰丙酸钾叶面喷施对黄土高原山地红枣生长发育及产量品质的影响。结果表明:叶面喷施稀释800倍的乙酰丙酸钾,对枣树的生长发育、产量和品质都有明显的促进作用,建议在黄土高原区红枣实际生产中采用稀释800倍的乙酰丙酸钾喷施。
9-year-old compact pear jujube was selected as the experimental material.The effect of potassium levulinate on the growth,yield and quality of jujube in the mountainous region of loess plateau were studied under field experiment,The results showed that diluting 800 times fertilizer level could improve the growth and development of jujube.Yield was improved significantly.Finaly,dluting 800 times fertilizer level was recommended in the jujube field planting in mountainous region of loess plateau.
