另外，北疆地區(qū)以機(jī)采棉為主，今年機(jī)采棉長(zhǎng)勢(shì)同樣較好。據(jù)石河子部分棉農(nóng)介紹，今年機(jī)采棉引進(jìn)的品種優(yōu)質(zhì)，采摘期可有效解決碎棉葉、地膜破塑料卷進(jìn)機(jī)器的風(fēng)險(xiǎn)，減少雜質(zhì)提升棉花的品質(zhì)。
截至22日，北疆地區(qū)棉花少量開裂，個(gè)別吐絮，部分手采棉已有少量采摘，但機(jī)采棉尚未開動(dòng)。根據(jù)時(shí)間推算，預(yù)計(jì)機(jī)采棉要等到9月中下旬才會(huì)陸續(xù)采摘。今年手采棉的拾花費(fèi)增至2-2.4元/公斤，拾花工依然難找，個(gè)別種植大戶打算高價(jià)聘請(qǐng)拾花工。
南疆地區(qū)阿克蘇、喀什、庫(kù)爾勒等三大棉區(qū)棉花長(zhǎng)勢(shì)普遍較好，據(jù)棉農(nóng)估計(jì)，今年單產(chǎn)增多沒(méi)有懸念。22日，一位阿克蘇棉農(nóng)介紹，今年播種570多畝，全部是手采棉，預(yù)計(jì)單產(chǎn)在400-410公斤/畝，較去年的395公斤/畝增5-15公斤/畝。之所以預(yù)判增產(chǎn)，主要依據(jù)是今年棉花坐桃、結(jié)鈴數(shù)較去年多1個(gè)左右/每株；另外，棉桃的飽滿度也較去年略好。
眼下，棉農(nóng)正在忙兩件事：一是加緊田間管理。今年收成如何，還要看鈴期的管理是否到位，不僅要除蟲治害，還要增水增肥保鈴桃；二是加緊棉花的預(yù)售工作。主要工作是是聯(lián)系周邊棉花加工廠，做好預(yù)售工作，保障今年收益。
