摘要
本文结合珠两优5298在安徽安庆地区的种植表现,总结了其高产栽培技术。2022—2024年,该品种在安庆望江县等12个示范点进行种植,株型直立上翘;生育期130~136 d;平均结实率85.77%、千粒重24.1 g,产量在8280~9000 kg/hm^(2);整精米率较好,米质优良;抗倒伏能力较强。其高产栽培技术包括及早播种(4月底至5月中旬播种育苗)、适时移栽、培育壮苗、保持秧田盘土湿润、根据秧苗长势施用“断奶肥”(尿素60~75 kg/hm^(2)),适时防治稻蓟马、恶苗病等苗期病虫害;根据秧苗素质、栽插时间等选择高速插秧机作业,按照设定检查并调试插秧机械,确定栽插株距、取秧量、深度;适时除草(喷施丁草胺等药剂进行土壤封闭,苗期喷施丁苄等药剂进行茎叶防除,苗后全田喷施30%丙草胺等药剂进行封闭);重施基肥(45%复合肥450~600 kg/hm^(2))、早施分蘖肥(高氮高钾复合肥225~300 kg/hm^(2))、补施穗肥(氯化钾112.5~150.0 kg/hm^(2));浅水栽秧、深水活棵、干湿交替促分蘖;大田生长期适时适药防治稻瘟病、纹枯病等病虫害。本文为该品种在相似地区进一步推广种植提供参考。
The planting performance of Zhuliangyou 5298 was combined in Anqing City,Anhui Province area,and its high yield cultivation techniques were summarized.From 2022 to 2024,this variety was planted in 12 demonstration sites,including Wangjiang County in Anqing City,with an upright and upward curved plant shape;the growth period was 130-136 days,with an average seed setting rate of 85.77%,a thousand grain weight of 24.1 g,and a yield of 8280-9000 kg/hm^(2);good polished rice yield and excellent rice quality;strong anti lodging ability.Its high yield cultivation techniques include early sowing(sowing and seedling cultivation from late April to mid May),timely transplanting,cultivating strong seedlings,keeping the soil of the seedling field moist,applying“weaning fertilizer”(urea 60-75 kg/hm^(2))according to the growth of the seedlings,and timely prevention and control of seedling diseases and pests such as rice thrips and bakanae disease;select high speed rice transplanter operation based on seedling quality,planting time,etc.,inspect and debug the transplanting machinery according to the settings,determine the planting distance,seedling amount,and depth;timely weed control(spraying pesticides such as butachlor for soil sealing,spraying pesticides such as butazone for stem and leaf control during the seedling stage,and spraying pesticides such as 30%propiconazole for sealing throughout the field after the seedlings);heavy application of base fertilizer(45%compound fertilizer 450-600 kg/hm^(2)),early application of tillering fertilizer(high nitrogen and high potassium compound fertilizer 225-300 kg/hm^(2)),and supplementary application of ear fertilizer(potassium chloride 112.5-150.0 kg/hm^(2));shallow water seedling planting,deep water live planting,alternating dry and wet conditions to promote tillering;appropriate pesticides should be used during the growth period of the field to prevent and control diseases and pests such as rice blast and sheath blight.This article provides a reference for further promotion and planting of this variety in similar regions.
