Effects of Soil Fert ilization and Plastic Film Mulching on Soil Fertility and Rice Yield in Newly Cultivated Land of Zhejiang Province
The newly cultivated land in Zhejiang Province has the prominent problems,such as poor soil fertility and low productivity,etc.This study explored the high yield cultivation technology of rice suitable for the reconstruction of the newly cultivated land in Zhejiang Province through multi-year field experiments.The results showed that,influenced by the fertility of newly cultivated farmland,among the 8 varieties participating in the rice variety screening experiment,Hanyou 73 was more suitable for planting on newly cultivated farmland and had a higher yield.Applying organic fertilizer to newly cultivated land could effectively improve soil fertility and increase rice yield.Applying the water saving with film mulching cultivation technique and organic fertilizer in the newly reclaimed farmland significantly increased rice yield,the rice yield of the treatment of mulching and applying Babe silkworm sand(11.25 t/hm2)increased by 36.76%compared to the treatment of no mulching and no applying organic fertilizer.It can be seen that planting rice on newly cultivated land with the application of organic materials for fertilization and water saving with film mulching cultivation,can achieve the goal of increasing rice yield.
