椰糠、有机肥与沙子不同配比基质对番茄穴盘苗生长的影响

【目的】筛选培育番茄优质壮苗的最佳基质配比,为新疆和田地区番茄穴盘育苗提供参考。【方法】以番茄品种欧官为材料,以椰糠、有机肥以及沙漠中的沙子为主要原料,按照不同比例进行配制,采用穴盘育苗的方式,以不同的育苗基质配比设置5个不同的处理和1个对照,在其他条件一致的情况下,测定番茄幼苗的株高、茎粗、最大叶面积、鲜重、干重、根长、根体积、可溶性糖、可溶性蛋白、叶绿素等指标,比较不同基质配比对番茄幼苗生长指标和生理生化指标的影响。【结果】各处理都对番茄幼苗的生长产生了影响,通过测定番茄幼苗的生长指标和生理生化指标,T3处理(椰糠∶沙子∶有机肥=20v∶1v∶1v)的配比对番茄苗的效果最好。【结论】椰糠∶沙子∶有机肥=20v∶1v∶1v的配比对番茄穴盘苗的生长有利,可作为新疆和田地区番茄穴盘育苗的基质配方。

Effects of Different Proportions of Coconut Husk,Organic Fertilizer and Sand on the Growth of Tomato Seedlings

【Objective】 Peat was the main substrate for tomato seedling in Hetian area of Xinjiang, and seedling costs were rather high. In this experiment, coconut husk, organic fertilizer and sand in desert were used as main raw materials to prepare tomato seedlings according to different ratios. The purpose of this experiment was to select the best ratio of high quality and strong seedlings of tomato in the hope providing reference for seedling raising of tomato in Hetian area. 【Method】 The tomato variety 'Ouguan' was used as test material and five different treatments and one control were set up with different substrate ratios with the method of raising seedlings with acupoints and plates. All other things being equal, plant height, stem diameter, maximum leaf area, fresh weight, dry weight, root length, root volume, soluble sugar, soluble protein and chlorophyll of tomato seedlings were measured. The effects of different substrate ratio on the growth and physiological and biochemical indexes of tomato seedlings were compared.【Result】All the treatments affected the growth of tomato seedlings. By measuring the growth index and physiological and biochemical indexes of tomato seedlings, it was found that T3 treatment (coconut bran: sand: organic fertilizer =20v: 1v: 1v) had the best effect on tomato seedlings. 【Conclusion】 The ratio of coconut husk: sand: organic fertilizer = 20v: 1v: 1v is beneficial to the growth of tomato hole seedlings, so it is recommended as the substrate formula for tomato seedling in Hetian, Xinjiang.
