二、注意事項1、棉(mian)(mian)(mian)花保苗集處理棉(mian)(mian)(mian)種(zhong)(zhong)的(de)(de)(de)過(guo)程(cheng)是棉(mian)(mian)(mian)種(zhong)(zhong)抗性的(de)(de)(de)鍛煉的(de)(de)(de)過(guo)程(cheng)。是讓(rang)棉(mian)(mian)(mian)種(zhong)(zhong)將(jiang)(jiang)試(shi)劑(ji)(ji)充分吸收到(dao)棉(mian)(mian)(mian)種(zhong)(zhong)內(nei)，從而達(da)到(dao)減(jian)少土壤鹽離子(zi)、病菌的(de)(de)(de)侵入，提高(gao)棉(mian)(mian)(mian)花苗的(de)(de)(de)抗逆能力的(de)(de)(de)目的(de)(de)(de)，其后效較(jiao)(jiao)長。而縮短浸(jin)種(zhong)(zhong)時(shi)間或(huo)一(yi)次(ci)(ci)(ci)浸(jin)種(zhong)(zhong)均不如(ru)(ru)分次(ci)(ci)(ci)浸(jin)種(zhong)(zhong)每次(ci)(ci)(ci)放(fang)置24小時(shi)效果好。2、經硫酸(suan)脫絨棉(mian)(mian)(mian)種(zhong)(zhong)或(huo)需機播時(shi)，可(ke)(ke)不用三(san)開一(yi)涼浸(jin)種(zhong)(zhong)，直(zhi)接(jie)用棉(mian)(mian)(mian)花保苗劑(ji)(ji)浸(jin)種(zhong)(zhong)即可(ke)(ke)。但三(san)袋試(shi)劑(ji)(ji)加水(shui)(shui)量分別為(wei)1.8公(gong)斤(jin)，浸(jin)種(zhong)(zhong)6公(gong)斤(jin)，其它步驟(zou)相(xiang)同(tong)。3、棉(mian)(mian)(mian)花保苗劑(ji)(ji)與防(fang)治(zhi)蟲類農(nong)藥(yao)同(tong)時(shi)使用時(shi)，待用保苗劑(ji)(ji)三(san)次(ci)(ci)(ci)浸(jin)種(zhong)(zhong)完成(cheng)后，播種(zhong)(zhong)前再(zai)拌(ban)農(nong)藥(yao)。4、用棉(mian)(mian)(mian)花保苗劑(ji)(ji)浸(jin)種(zhong)(zhong)后，如(ru)(ru)棉(mian)(mian)(mian)種(zhong)(zhong)較(jiao)(jiao)濕不宜播種(zhong)(zhong)時(shi)，可(ke)(ke)稍微風吹一(yi)會(hui)兒或(huo)曬一(yi)會(hui)兒，但不要(yao)讓(rang)種(zhong)(zhong)子(zi)失(shi)水(shui)(shui)過(guo)多(duo)，否(fou)則會(hui)影(ying)響(xiang)(xiang)效果。5、浸(jin)種(zhong)(zhong)時(shi)如(ru)(ru)天(tian)氣干(gan)燥，種(zhong)(zhong)子(zi)失(shi)水(shui)(shui)快(kuai)，可(ke)(ke)將(jiang)(jiang)種(zhong)(zhong)子(zi)用濕布(bu)蓋上；如(ru)(ru)氣溫(wen)(wen)偏高(gao)時(shi)（日平均氣溫(wen)(wen)20℃以上），可(ke)(ke)適當縮短每次(ci)(ci)(ci)浸(jin)種(zhong)(zhong)放(fang)置時(shi)間，以免(mian)種(zhong)(zhong)子(zi)發芽較(jiao)(jiao)長兒影(ying)響(xiang)(xiang)播種(zhong)(zhong)。
