免耕板播小麦是我县田少人多、复种指数较高地区稻稻麦三熟制的主要栽培方式,约占全县小麦面积的10%左右。过去,这部分小麦常因田湿难整,或粗糙耕播或等田爽土迟播,播种质量差、季节晚、出苗率低,苗数不足,产量很低,有的甚至有播无收。自农业生产责任制后,三熟制地区广大农户改耕播为免耕板播小麦,其效果较好。据多点调查,板播麦的产量可达500斤左右,典型田块达600斤以上,比耕播迟播的每亩要增产150—200斤,还大大增加了保收面积。实践证明,免耕板播方式是变稻稻麦迟播低产为早播高产的有效途径。
No-tillage Sowing wheat is a county of many young people, multiple cropping index rice paddy rice three main system of cultivation, accounting for about 10% of the county’s wheat area. In the past, this part of the wheat was often poorly wetted by fields, rough farming or late blooming of soaked soils. The quality of sowing was poor, the season was late, the rate of emergence was low, the number of seedlings was low, the yield was low, and some even had no crop yield. Since the responsibility system for agricultural production, the majority of farmers in the three areas planted sowing as no-tillage sowing wheat, the effect is better. According to more surveys, the output of plate sowing wheat can reach about 500 kilograms, with a typical land piece of more than 600 kilograms, an increase of 150-200 kilograms per mu than that of sowing and sowing, which also greatly increases the area covered by the guarantee. Practice has proved that no-tillage sowing is an effective way to change the late rice sowing and low yielding rice for early sowing and high yield.
