二、关键技术

(一)适期播种,培育壮苗

水稻。网上兼职赚钱指南水稻主推强化栽培、旱育秧、机插秧和免耕直播栽培等节本高效技术。我市当前水稻主推品种适宜播期为3月下旬至4月上旬,普及推广水稻旱地育秧或塑盘育秧培育壮秧。

1.旱地育秧:选土壤肥沃,向阳的地或田作秧母地,按秧本比1:15留足。播种前,先结合整地作厢全层施入底肥(每分地施尿素2-3公斤、过磷酸钙5公斤、粪水5担),按1.7米包沟开厢,沟宽30厘米;再浇足水,使苗床充分湿润,并施好辛拌磷(每分地施60克)防地下害虫;种子经泡种24小时左右后,捞出滤干用“旱育保姆”将稻种包衣,每公斤“旱育保姆”包衣2.5公斤稻种,然后及时均匀撒播于厢面播种,盖种后喷施除草剂(每分地施旱秧净10毫升),最后搭拱盖膜。出苗期注意保湿和防止高温烧苗,见青后揭膜炼苗。秧苗期可视长势施肥1至2次,以粪水结合尿素泼浇。

2.塑盘育秧:每亩本田准备428孔的塑料秧盘50张,壮秧剂1公斤,稻种1.25公斤(消毒、浸泡、催芽)。⑴旱育旱管方式:选土壤肥沃、向阳、水源方便的地块,整细整平,施足底肥,按1.6米包沟开厢,沟宽30厘米,深15厘米。厢面浇足水,耥平厢面并耥出泥浆,整齐平整地安放好秧盘,先用5公斤营养土拌500-600克壮秧剂撒于50个秧盘内(余下400-500克壮秧剂在一叶一心期兑水泼施),再撒营养土装至秧盘三分之二满,均匀播种后,再用营养土盖种,(营养土须是肥沃的菜地土经捣碎过筛的细土,50个秧盘约需70-80公斤)。用竹片刮去多余细土,以免串根。播种后浇足水,搭拱盖膜。出苗期注意保湿和防止高温烧苗,见青后揭膜炼苗。⑵水育旱管方式:在大土区整地较困难,有水源的可采取水育旱管方式。其整田、开厢方式与湿润育秧基本相同。开厢后待厢面泥浆沉稳(一般1-2天),再耥平厢面,安放秧盘后均匀撒入壮秧剂,然后用厢沟中不带硬块的泥浆装满盘孔,待泥浆沉淀后(一般有三分之二满)均匀播种,然后用肥沃的过筛细土盖种,最后用竹片刮去秧盘表面泥土。播种后搭拱盖膜,见青后揭膜炼苗。

玉米。网上兼职赚钱指南玉米主推增密、增肥和覆盖栽培为主的玉米高产配套技术。春玉米实行育苗移栽的在3月下旬前播种,直播的在4月上旬前播种,积极推广地膜育苗移栽和地膜覆盖栽培。可采用玉米专用塑料育苗盘,将肥沃过筛细土作营养土,先用营养土装盘至三分之二满,然后播种,每孔播一粒种子,播后再用营养土盖种至满盘,刮去多余细土,最后将盘整齐摆放在整好的苗床地上,浇足水,搭拱盖上薄膜。出苗前注意保温保湿,出苗后注意防高温烧苗,一叶一心选晴天揭膜炼苗,二叶一心及时移栽。

(二)适时早栽,栽足基本苗
