1981年和1982年日本秋田县农业试验场的水稻行侧条施肥法的试验结果证明,行侧条施肥的产量比一般全层施肥的增产5—10%。试验还得出从前期开始显著增加株高、分蘖数、干物重,能促进早生快发。同时,还可减少肥料的利用率,防止环境污染。另外,通过插秧结合施肥,能改进作业体系,合理调节劳动力。施肥应注意以下几点:1.行铡条施肥使土壤局部存在较高的养分浓度,水稻从移植后开始能迅速吸收利用,促使其壮苗。但是,行侧条施肥却不能很好地促进徒长或其它障碍而致吸肥力弱的禾苗早生快
The test results of side row fertilization by rice in 1981 and 1982 in Akita prefecture agricultural experiment station show that the yield of side row fertilization is 5-10% more than that of general full layer fertilization. The experiment also showed that the plant height, tiller number and dry matter weight were significantly increased from the early stage, which can promote the rapid onset of early-born. At the same time, fertilizer can also reduce the utilization rate, to prevent environmental pollution. In addition, fertilization by planting seedlings, can improve the operating system, a reasonable adjustment of the workforce. Fertilization should pay attention to the following points: 1. Sliver tuber fertilization to soil a higher part of the local nutrient concentration, rice from the beginning after transplantation can quickly absorb and promote their seedlings. However, the sideline fertilization can not be good at promoting leggy or other obstacles caused by low fertility seedlings early seedlings faster
