叶面肥对无土栽培樱桃番茄性状的影响及产量与植株性状的数学模型研究

为了探索樱桃番茄无土栽培在海南热带地区种植效果及植株产量效应，本研究通过增施不同量叶面肥，设计3种处理、3次重复随机试验，并对试验最佳效果的植株产量、株高和茎粗建立相关数学模型。结果表明，增施叶面肥较传统施肥有明显增产效果，平均增产2250 kg/hm²，增产20.2%。而樱桃番茄株高与产量、茎粗与产量具有显著相关性，其模型分别为Y_单株产量=(47.92060X_{株高-24.95763)² (P= 0.0114＜0.05)和Y单株产量=(61.885X茎粗-46.97988)² (P=0.0372＜0.05)，符合植株生长趋势变化。因此，在海南开展樱桃番茄无土栽培是可行的，且可以通过调控来调节植株生长情况从而提高产量，增加经济效益。}

Effects of Soilless Culture on Cherry Tomato Characters after Using Foliar Fertilizer and Study on the Mathematical Model of Pplant Characters and Yield

The aim was to explore the cherry tomato soilless cultivation effect and plant production in tropical areas of Hainan. In this paper, different foliar fertilizers were used by 3 treatments and 3 times for yield contrast test. The mathematical model of plant characters and yield were built for best effect test. It showed that there was 20.2% yield-increasing than traditional fertilization after using foliar fertilizer, about increasing 2250 kg/hm^2. The mathematical model of yield and plant height was YYield=（47.92060XHeight-24.95763）2（P=- 0.0114〈0.05）, yield and stem width was YYield=（61.885Xwidth-46.97988）2 （P=-0.0372〈0.05）. So, development of soilless euhure for cherry tomato in Hainan was feasible, and it could be adjusted by regulating the growth of plants to improve yield, increase economic benefits.
