摘        要
 為探討不同地膜覆蓋對春植花生的增產效應，以普通地膜覆蓋栽培處理為對照研究了C306常規除草地膜、7－2－6除草地膜、CJ7－3－9除草地膜對仲愷花2號生長發育以及產量的影響。結果表明：在產量方面，CJ7－3－9除草地膜、C306常規除草地膜、7－2－6除草地膜栽培處理每667m2干重平均產量為275.09kg、259.76 kg和257.38 kg，高于普通地膜栽培處理238.31kg，增產都達到顯著差異標準。在生長發育形態方面，CJ7－3－9除草地膜栽培處理平均分枝數8.8條，主莖青葉數8.10片，第一側枝長49.88cm，結莢期葉面積指數3.91，比普通地膜栽培處理多1.5條，多0.62片，長9.63cm，多1.25；相反，其主莖高為35.01cm，比普通地膜栽培處理少12.2cm。在雜草防效方面，三種地膜中CJ7－3－9處理的草株防效平均為96.46％，除草效果最好，C306處理的草株防效平均為93.81％，除草效果次之，這是CJ7－3－9除草地膜處理產量最高、C306常規除草地膜產量次高的原因之一。由于雜草少，種間競爭少，所以花生生長得好，產量就高。這表明在三種除草地膜中，CJ7－3－9除草地膜最適合應用于花生栽培，C306常規除草地膜次之。

Effect of mulching plastic on the Growth and the Output of Spring-planting Peanut 
  
 Abstract: A series of experiments were conducted to study the Growth and Output of Spring-planting Peanut_Zhongkaihua No.2 treated with the C306 weeding mulching plastic, 7-2-6 weeding mulching plastic and the CJ7-3-9 weeding mulching plastic. The results showed that: The dry fruit yield per mu of peanut field covered with the CJ7-3-9 weeding mulching plastic, the C306 weeding mulching plastic and the 7-2-6 weeding mulching plastic were 275.09kg, 259.76kg, 257.38kg respectively, while that of the control was 238.31kg, and there was significant difference between treatments and controls. In respect of the developing shape, the average branches of Peanut treated with the CJ7-3-9 weeding mulching plastic was 8.8, which was 1.5 more than that of the control; the green leaves of the main stem of the above treatment was 8.10, which was 0.62 more than that of the control; the length of the first side branch of the above treatment was 49.88cm, which was 9.63cm longer than that of the control; the area exponent of the leaves of the above treatment was 3.91, which was 1.25 more than that of the control; but the height of the main stem of the above treatment was 35.01cm, which was 12.2cm lower than that of the control. The weed control efficiency of the CJ7-3-9 plastic achieved 96.46% which was the best between treatments and controls, while the weed control efficiency of the C306 plastic achieved 93.81% which was better. The good growth and high yield of the above treatments owed to the high weed control efficiency mainly. Analysing the above indicators, the CJ7-3-9 weeding mulching plastic was the best among the three weeding mulching plastic, while the C306 weeding mulching plastic was better.
