摘要
在滴灌施肥条件下,采用311A—D最优饱和设计,通过温室小区试验,研究了水肥耦合效应对番茄产量的影响。通过主因素、单因素效应分析,定量地评价了灌水下限、氮肥用量和钾肥用量与番茄产量的关系,提出了目标产量的最优水肥组合方案。
Under the condition of drip fertilization by using a 311A-D optimum design, effect of interaction between water and fertilizer coupling on tomato cultivation in greenhouse was studied by field experiment. Effects of water and fertilizers on tomato yield were studied quantitatively based on main and single factors effect analysis.This study Provides a optimal composite scheme of water and fertilizer for a aimed yield.
