The effects of different-colored polyethylene mulches on the quantity and spectra of reflected light, earliness of fruit set, fruit yield and quality, and root-knot disease were studied in field-grown, staked tomato (Lycopersicon esculentum). White mulch reflected more photosynthetic light and a lower far-red-to-red ratio than red mulch, whereas black mulch reflected less than 5 percent of any color. Soil temperatures and fruit yields were recorded for tomato plants inoculated with Meloidogyne incognita race 3 at initial populations of 0, 1,000, 10,000, 50,000, or 100,000 eggs/plant and grown over black, white, or red plastic mulch in both spring and fall. Soil temperatures were lower under white mulch than under red or black mulch. Tomato yields declined as inoculum level increased. Plants grown over red mulch in the spring and inoculated with 50,000 eggs of M. incognita had greater early marketable yields than similarly inoculated plants grown over black or white mulch. Tomato plants inoculated with 100,000 eggs and grown over white mulch or red mulch in the spring had greater total yields per plot than similar plants grown over black mulch (7.39 kg and 7.71 kg vs. 3.65 kg, respectively).
在田间种植的立架番茄（Lycopersicon esculentum）上，研究了不同颜色的聚乙烯地膜对反射光的数量和光谱、坐果早熟性、果实产量和品质以及根结线虫病的影响。白色地膜比红色地膜反射更多的光合光且远红与红的比率更低，而黑色地膜对任何颜色光的反射均低于5%。记录了接种南方根结线虫3号小种、初始虫口密度分别为0、1000、10000、50000或100000个卵/株的番茄植株在春季和秋季覆盖黑色、白色或红色塑料地膜时的土壤温度和果实产量。白色地膜下的土壤温度低于红色或黑色地膜下的温度。番茄产量随接种量的增加而下降。春季在红色地膜上生长且接种50000个南方根结线虫卵的植株，其早期可上市产量高于在黑色或白色地膜上生长的类似接种植株。春季接种100000个卵并在白色地膜或红色地膜上生长的番茄植株，其每块地的总产量高于在黑色地膜上生长的类似植株（分别为7.39千克、7.71千克和3.65千克）。
