甘肃陇南油橄榄配方施肥试验研究

Experimental Study on Formulated Fertilization of Olive in Longnan of Gansu Province

施肥是影响油橄榄丰产稳产的关键性措施。通过不同施肥配方及施肥量对不同品种新梢生长量及鲜果产量的影响试验得出:施用有机肥+无机肥的混合肥,于11月份施5 kg的菜籽饼,1 kg过磷酸钙、0.5kg硫酸钾、200 g硼肥;于4月、6月、8月各施0.1 kg尿素,于每年的4月、7月、11月灌3次水,可使单株产量由2.4 kg提高到18.2 kg,净增产15.8 kg,增产增效显著。

Fertilization is a critical measure affecting high and stable yield of olive trees. Based on study of the effect of different formulas and quantities of fertilization on shoot growth and fruit yield of different varieties, the re- suits showed： Applying the compost of organic and inorganic fertilizer, 5 kg rapeseed cake, 1 kg calcium superphos- phate, 0.5 kg potassium sulphate, and 200 g boron fertilizer in November; applying 0.1 kg urea in April, June, and August ＇respectively, irrigating water 3 times in April, July and November every year, which could make the yield of per plant increase from 2.4 kg to 18.2 kg, and effects of increasing yield and efficiency were significant.
