按照不完全“3414”肥料效应田间实验方案,连续2年在贵州省台江县革一乡进行了8个氮磷钾基肥水平处理对枇杷结果母枝生长及结果影响试验。结果表明,处理N1P1K1+牛粪50 kg的综合效果最佳,中心花枝、侧生花枝、采果痕枝花枝3类结果母枝的茎粗、叶片数、成花枝率、坐果花枝率等均显著高于对照,单株产量25.1 kg,比对照增产14.5 kg。折算后的基肥施用量为株施牛粪50 kg+复合肥(N∶P2O5∶K2O=1∶1∶1,有效成分含量为45%)1.4 kg。
According to incomplete “3414 ” fertilizer effect field experiment program, 8 years of N, P and K fertilizer treatment on the growth of loquat fruit and the result of test were conducted in Geyi Village, Taijiang County, Guizhou Province for two consecutive years. The results showed that the combination of N1P1K1 + cow dung 50 kg was the best. The stem diameter, the number of leaves, the rate of flowering branches and the rate of flowering branches of the three kinds of results of central flowering branches, lateral flowering branches and fruit picking marks were significantly higher In the control, the yield per plant was 25.1 kg, which increased by 14.5 kg compared with the control. After conversion, the basal fertilizer application rate was 50 kg of plant manure plus 1.4 kg of compound fertilizer (N: P2O5: K2O = 1: 1: 1, the active ingredient content was 45%).
