摘要:

探讨了稻鸭共作栽培模式对优良食味水稻品种南粳46植株生长性状与产量性状的影响。结果表明,稻鸭共作模式在一定程度上降低了南粳46的株高和有效穗数,但增加了每穗总粒数,提高了结实率。虽然稻鸭共作栽培模式产量不及常规栽培,但能显著提高经济效益,每667 m2经济效益比常规栽培提高525.05元。同时,稻鸭共作模式减少了化肥、农药的使用,保护了农业生态环境,提高了水稻生产的安全性,为农业的可持续发展提供了一种途径。

Abstract:

This paper investigated the effects of rice-duck integrated farming cultivation pattern on growth traits and yield traits of Nangeng 46. The results showed that rice-duck integrated farming reduced the plant height and effective panicle number of Nangeng 46, but increased grains number per panicle and seed-setting rate. Compared with conventional cultivation, the rice-duck integrated farming is lower in yield but more economic benefit, the economic benefit per 667 m2 was 525.05 yuan higher than that of conventional cultivation. At the same time, the rice-duck integrated farming reduced the application amount of chemical fertilizers and pesticides, protects the agricultural ecological environment, improves the safety of rice production, and provided a way for the sustainable development of agriculture.

Key words: Nangeng 46, rice-duck integrated farming pattern, yield, economic benefit
