钾素营养对猕猴桃产量和品质有重要影响,为了进一步探索钾素营养的作用特点、调控方法,修正和完善猕猴桃施肥配方,建立更为先进、完善、精确的施肥指标体系并指导大田生产。1试验方法1.1试验地点及品种陕西省沙河营镇梁家庵村5组李建荣试验点,位于东经107°14′59.5″、北纬33°07′15.2″、海拔476m;供试品种为秦美(18年生),栽植密度3.3×3.0m(67株/亩);供试土壤为中肥力沙壤土(养分含量见表1)。
In order to further explore the characteristics and regulation of potassium nutrition, potassium nutrition was amended and refined to improve the yield and quality of kiwifruit. To establish a more advanced, complete and accurate fertilization index system and guide the field production. 1 Test methods 1.1 Test sites and varieties Li Jianrong test station of 5 groups in Liangjiaan Village, Shaheying Town, Shaanxi Province was located at 107 ° 14’59.5 “E and 33 ° 07’15.2” N at an elevation of 476m. The test variety Qinmei (18 years) ), Planting density 3.3 × 3.0m (67 plants / mu); soil test medium fertile sandy loam (nutrient content shown in Table 1).
