Effects of W-Shaped Plastic Mulching Method on Dry Matter Accumulation and Yield in Peanut Cultivation

Under field conditions, the effects of W-shaped plastic mulching method on dry matter accumulation and yield of peanut cultivation was studied using Arachis hypogaea cv. Qinghua 5 as test material. The results showed that the W-shaped plastic mulching method of peanut cultivation significantly improved the dry matter accumulation of stem, leaves, peg, pod and the biomass yield, promoted the quantity of seed setting and pod development. Moreover, W-shaped cultivation method increased fruit number per plant and the fruit weight. More dry matter accumulated to pod, the economic coefficient and pod yield increased as well. Therefore, W-shaped plastic mulching method of peanut cultivation was a high yield, high efficiency, and practical technique.
