摘要:
福州平原人多地少,光热资源丰富,据稻田研究结果,推广复种轮作三熟制,不但经济产量和经济效益高,且改善土壤理化性质,增加地力。三熟制比二熟制有较高的生产力。虽然从土壤中带走的养分较多,由于增加了土壤有机质来源,所以土壤并未衰退。麦、稻、稻三熟制有较高的生产力,在增施肥料的条件下,种麦不会损稻。
Abstract:
In the plainfield of Fuzhou area, the population density is very high but the cultivable land is limited, and the resources of sunshine and heat energy are very wealthy. According to our research data from rice fields the extension of multiple cropping and triple cropping system annually not only can get high economical and effective production, but also can improve the physical and chemical character of soil and increase soil fertility. The productivity of triple cropping system is higher than that of double cropping system,Because of increasing soil organic matter content though the nutrient has been taken away,the soil fertility is not depleting.The triple cropping system of wheat-rice-rice has higherproductivity. Under the condition of increasing fertilizers to crops, plantation of wheat does notdamage rice.
