Abstract

Abstract: The main aim is to find out the influence of using coloured plastic mulches (blue, white, green, red, black and white on black) compared with a mulch-free treatment on the root zone temperature, growth and productivity of broccoli. The results indicated that the highest and lowest mean root zone temperatures were recorded the in the dark-coloured mulches (blue, green, red and white on black) and in the light-coloured mulches (white), respectively, in both the winter and spring seasons. The average shoot length, leaf number and root volume of the broccoli for all the treatments was higher in the spring season compared with those of the winter season. The highest marketable head fresh weight values were 449.6 and 451.0 g found in the black mulch, while the lowest values were 391.4 and 397.5 g found in the winter and spring seasons for the red mulch, respectively. The N, P, K, Ca and Mg concentrations in the broccoli heads ranged from 2.0 to 2.8%, 0.9 to 1.0%, 2.7 to 3.6%, 1.9 to 5.9% and 0.5 to 0.89%, respectively, for all the treatments.

彩色地膜栽培西兰花根区温度、生长和产量的变化

摘要：主要目的是研究彩色塑料膜（蓝色、白色、绿色、红色、黑色和白色）与无膜处理对西兰花根区温度、生长和生产力的影响。结果表明，在冬季和春季，深色覆盖物（黑色上的蓝色、绿色、红色和白色）和浅色覆盖物（白色）分别记录了最高和最低的平均根区温度。所有处理的西兰花的平均茎长、叶数和根体积在春季都高于冬季。黑色覆盖物的可销售头鲜重最高值分别为449.6和451.0 g，而红色覆盖物的最低值分别为391.4和397.5 g，分别出现在冬季和春季。所有处理的花椰菜头中的N、P、K、Ca和Mg浓度分别为2.0%至2.8%、0.9%至1.0%、2.7%至3.6%、1.9%至5.9%和0.5%至0.89%。
