做好棚室番茄植株调整内容摘要:
2、中熟和中熟品种;三是一秆半整枝。 先采用双秆整枝,待侧枝着生 12 个花序后即摘心,此法适于自封顶品种。 茄侧枝萌发力强,往往几个侧枝同时生长,为促进根系生长和发棵,最好打权时间可推迟到杈长 3 厘米左右,以后可在 12 厘米长时及时抹去。 打杈一般与绑蔓结合,要先打健株,后打病株,以防病害相互传染。 般情况下,当果枝上的果穗长足一定数目时,果穗前留有 2 片叶摘去植株顶端。 茄生长后期,下部叶片黄化干枯,失去光合机能,影响通风透光,应将黄叶、病叶、密生叶打去,然后深埋或烧掉,但有正常机能的叶片不能摘。 用激素处理花之前,若每穗花的数量太多,应将畸形花及特小花摘除,每穗保留 45 朵即可。 激素处理后,若坐果太多,往往会造成果实大小不一,单果重量下降,影响果实品质。 因此,应尽早疏果,一般早熟品种每穗留果 45 个,晚熟品种留果 34 个即可。 专利查询。做好棚室番茄植株调整
