無(wú)錫試驗(yàn)多項(xiàng)機(jī)插秧新技術(shù)

2023-08-09 10:00:24 來(lái)源：江蘇省無(wú)錫市農(nóng)業(yè)農(nóng)村局 閱讀量：18366 評(píng)論

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】為進(jìn)一步提升水稻機(jī)插秧作業(yè)質(zhì)量和作業(yè)效率，江蘇省無(wú)錫市在今年夏種期間積極引進(jìn)新機(jī)械、新技術(shù)，開展多項(xiàng)機(jī)插秧新技術(shù)試驗(yàn)示范，為推動(dòng)農(nóng)業(yè)高質(zhì)量發(fā)展提供科技支撐。
 
　　一是首創(chuàng)水稻旱插技術(shù)。
  
　　針對(duì)部分高標(biāo)準(zhǔn)農(nóng)田建成第一年因土壤沉淀不足、容易陷車等問題，江陰市在總結(jié)去年經(jīng)驗(yàn)教訓(xùn)基礎(chǔ)上，探索出水稻田旱插技術(shù)：一是采用噴滴灌技術(shù)進(jìn)行育秧，水量及秧苗生長(zhǎng)情況可控，秧苗更加耐旱；二是水稻田旱插選在多云或陰天進(jìn)行，及時(shí)上水，提高秧苗成活率；三是加強(qiáng)后期田間除草管理，促進(jìn)水稻生長(zhǎng)。從目前長(zhǎng)勢(shì)來(lái)看，采用旱插技術(shù)的秧苗成活率達(dá)到90%以上，為易沉降下陷農(nóng)田實(shí)施水稻機(jī)插提供有效的解決方案。
 
　　二是水稻機(jī)插用上“黑科技”。
  
　　為減少農(nóng)業(yè)面源污染、提高糧食產(chǎn)量，濱湖區(qū)和新吳區(qū)試驗(yàn)水稻機(jī)械覆膜插秧技術(shù)，先給稻田蓋上一層可降解黑色地膜，然后在膜上打孔，再把秧苗透過孔洞插在田里。在自然界微生物的作用下，地膜60天左右就能完全降解為水、二氧化碳和少量有機(jī)質(zhì)等物質(zhì)，對(duì)土壤和作物無(wú)毒副作用。該技術(shù)通過農(nóng)機(jī)與農(nóng)藝高度融合的一體化高效作業(yè)，是水稻控草的一大科技突破，既減少了稻田草害，降低了除草的人力成本，又減少了化學(xué)農(nóng)藥除草引起的面源污染。
 
　　三是寬窄行插秧機(jī)插出“科技范”。
  
　　惠山區(qū)聯(lián)合北大荒集團(tuán)引進(jìn)寬窄行插秧機(jī)，將水稻插秧行間距設(shè)置為寬行與窄行間隔栽插，寬行33-40厘米，窄行16-20厘米，每平方米可增加穴數(shù)5穴，插秧密度比普通插秧機(jī)高17%-18%，具有提高水稻的光能利用率、有效降低稻田有害生物影響、邊際增產(chǎn)效應(yīng)明顯和利于機(jī)械作業(yè)的優(yōu)勢(shì)，從而達(dá)到水稻長(zhǎng)勢(shì)好、抗倒伏、產(chǎn)量高的效果。下一步，無(wú)錫市將組織技術(shù)專家對(duì)試驗(yàn)項(xiàng)目進(jìn)行跟蹤指導(dǎo)和對(duì)比測(cè)試，全面總結(jié)技術(shù)要點(diǎn)，形成可復(fù)制可推廣的典型經(jīng)驗(yàn)。

下一篇：相城開展水稻四新技術(shù)觀摩培訓(xùn)活動(dòng)
