赣花92-01花生施用叶面肥的肥效研究

目的]为提高赣花92-01的种植效益。方法]按磷酸二氢钾3kg/hm2+尿素3kg/hm2+硼砂1.5kg/hm2,加水1200～1500kg自制叶面肥,研究喷施叶面肥对赣花92-01产量和质量的影响。结果]喷施叶面肥的花生株高、每蔸分枝数、每蔸稿秆重和每蔸荚果数均有不同程度的增长。百果重、百仁重和每蔸产量分别提高2.47%～3.64%、4.02%～5.73%和9.27%～22.10%,每蔸饱果数提高7.50%～13.86%,均以喷施叶面肥1次的生物性状表现最好。喷施叶面肥1次的产量最高,为3748.54kg/hm2,其次为喷施叶面肥2次的,分别比不喷叶面肥处理增产28.16%和15.28%。喷施叶面肥2次的稿秆产量最高,为6601.95kg/hm2。结论]在花生生长中后期,合理增施叶面肥能有效提高花生生物性状,改善花生的外观品质和质量,增产效果极其显著。

Fertilizer Efficacy Experiment of Applying Leaf Fertilizer on Ganhua 92-01

Objective The aim was to enhance the planting benefit of Ganhua 92-01.Method The self-made leaf fertilizer was produced by adding water 1 200～1 500 kg/hm2 to the mixture of 3 kg/hm2 monobasic potassium phosphate,3 kg/hm2 urea and 1.5 kg/hm2 borax.The influence of spraying leaf fertilizer on the yield and quality of Ganhua92-01 was studied.Result The plant height,branching number per plant,stem weight per plant and pod number per plant of peanut sprayed with leaf fertilizer all increased to different degrees.100-pod weight,100-kernel weight and yield per plant increased 2.47 %～3.64 %,4.02 %～5.73 % and 9.27 %～22.10 % resp.,with plump pods number per plant increasing 7.50 %～13.86 %.The biological characteristic perform of spraying leaf fertilizer for once were all best.The yield of spraying leaf fertilizer for once were highest(3 748.54 kg/hm2),the second was that of spraying leaf fertilizer for twice,increasing 28.16 % and 15.28 % resp.than that of spraying no leaf fertilizer.The stem yield of spraying leaf fertilizer for twice was highest,being 6 601.95 kg/hm2.Conclusion In the middle and late growth period of peanut,increasing leaf fertilizer reasonably can enhance the biological characteristics of peanut effectively,improve the appearance quality and quality,with extremely significant yield-increasing effect.
