摘要：

新垦耕地存在土壤肥力差、生产力低等突出问题。本研究通过多年多点田间试验，探究了适宜浙江省新垦耕地改造的水稻高产栽培技术。结果表明，受新垦农田肥力影响，参加水稻品种筛选试验的8个品种中，旱优73较适合在新垦耕地种植，产量较高；在新垦耕地施用有机物料可以有效提升土壤地力水平，增加水稻产量；在新垦农田采用覆膜节水栽培并施用有机物料明显提升水稻产量，其中，覆膜+施用巴贝蚕沙（11.25 t/hm2）处理下，旱优73的产量比不施肥+不覆膜处理显著增加36.76%。可见，在新垦耕地上种植水稻，通过施用有机物料培肥和覆膜节水栽培，能达到提高土壤肥力和水稻产量的目的。

Abstract:

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.
