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.
