摘要
以黑彤K-8西瓜为试验材料,用田间小区试验的方法研究了控释肥对西瓜生育期、植株生长及产量的影响。结果表明,控释肥能促进西瓜早熟3~6 d;相对于习惯施肥,控释肥对植株的生长也有明显的作用;而且对西瓜的产量具有显著的提高作用,在等养分施用情况下与习惯施肥相比,增产幅度为22.32%,而且在减少20%养分用量的情况下,增产幅度仍可达到10.60%;等量控释肥、减量控释肥、减氮控释肥处理的肥料生产率分别为习惯施肥处理的2.28、2.01、1.32倍。
Taking the watermelon Heitong K-8 as meterial,the field experiment was conducted to study effect of controlled-release fertilizer on growth period,plant growth and yield of watermelon.The results showed that controlled-release fertilizer could promote watermelon maturity in advance for 3~6 d earlier than control.Compared to conventional fertilizer,controlled-release fertilizer also had significant effect on plant growth.Moreover,it also could increase yield of watermelon significantly,which could increase by 22.32% or 10.60% than that of conventional fertilizer when using 80% of fertilizers.The fertilizer productivity of equivalent,decreased and nitrogen-dcreased controlled-release fertilizer were 2.28 times,2.01 times and 1.32 times of accustorned fertilization respectively.
