就核桃定植时和定植后施肥量和灌水量对核桃树生长的影响进行研究。在土壤肥力相同的条件下,通过连续4年不同的施肥量、灌水量对比试验,结果表明,株施尿素50 g+磷肥20 g+钾肥20 g+浇水40 kg ,每年3月和10月各浇水追肥1次,其树高、地径和冠幅生长量明显高于对照,在处理后期(第四年)施肥量的增加要视水分状况而定,否则会抑制核桃树生长。
就覈桃定植時和定植後施肥量和灌水量對覈桃樹生長的影響進行研究。在土壤肥力相同的條件下,通過連續4年不同的施肥量、灌水量對比試驗,結果錶明,株施尿素50 g+燐肥20 g+鉀肥20 g+澆水40 kg ,每年3月和10月各澆水追肥1次,其樹高、地徑和冠幅生長量明顯高于對照,在處理後期(第四年)施肥量的增加要視水分狀況而定,否則會抑製覈桃樹生長。

The effects of fertilizer amount and irrigation amount on walnut growth before and after field planting was analyzed in this paper .Under the same conditions of soil fertility , by four consecutive years contrast test of different fertilization and irrigation , it is concluded that:the tree height , ground diameter and crown growth were significantly higher than the control by watering and fertilizer individual plant with urea 50 g+p 20 g+k 20 g+water 40 kg in March and October every year .The increase of fertilizer rate (4 years) in the late processing depends on the moisture condition , otherwise it will inhibit the growth of trees.
