套条播、脚踏条播是苏南晚茬麦地区小麦的一种抗湿争早苗的应变播种技术.在秋播多雨年份,套条播和脚踏条播比灭茬免耕机条播播种期可提前7～10天,分蘖期提前20～40天,有利于形成早苗争大穗多粒.但是由于肥料施于土表,养分流失多,植株根系下扎浅,因而后期严重脱力早衰,在灌浆高峰期,灌浆速率比灭茬免耕机条播麦降低46.9%,最终千粒重降低2～3g.
Set of sowing, footbeds is a southern Jiangsu wheat crop wheat in the late wheat varieties of anti-humidity seedling strain sowing technology.In the rainy autumn season, sets of sowing and foot sowing than stubble tillage machine sowing sowing period can be advanced 7 ~ 10 days, tillering stage 20 to 40 days in advance, is conducive to the formation of early seedling big spike and more grain.But due to fertilizers applied to the soil surface, nutrient loss, plant roots tie shallow, and thus the late serious offspring premature decline in the grouting peak, The grain filling rate was 46.9% less than that of stubble tillage machine, and the final grain weight was reduced by 2 ~ 3g.
