導(dǎo)讀：江蘇省鹽城市建湖縣臨近夏糧收獲之際，小麥機(jī)收減損工作出現(xiàn)一些問題，主要表現(xiàn)在：作業(yè)前機(jī)具準(zhǔn)備工作不足。

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】江蘇省鹽城市建湖縣臨近夏糧收獲之際，小麥機(jī)收減損工作出現(xiàn)一些問題，主要表現(xiàn)在：作業(yè)前機(jī)具準(zhǔn)備工作不足。
 
　　一是忽視前期機(jī)具維修保養(yǎng)。從事機(jī)收作業(yè)的農(nóng)機(jī)手往往學(xué)歷不高，缺少農(nóng)機(jī)系統(tǒng)專業(yè)的學(xué)習(xí)，存在只會買機(jī)用機(jī)、不會養(yǎng)機(jī)修機(jī)的問題，機(jī)具作業(yè)前的維護(hù)保養(yǎng)不到位。二是機(jī)具更新成本高，現(xiàn)役機(jī)具很難實(shí)現(xiàn)更低的機(jī)損率。“好機(jī)不便宜，便宜沒好機(jī)”這是農(nóng)機(jī)手們廣為流傳的順口溜，再加上收割機(jī)市場產(chǎn)品品質(zhì)和性能不一，不少農(nóng)機(jī)手會選擇二手機(jī)或者便宜點(diǎn)的、參數(shù)可能虛標(biāo)的農(nóng)機(jī)裝備，導(dǎo)致農(nóng)機(jī)作業(yè)時“掉鏈子、跟不上”的現(xiàn)象發(fā)生。機(jī)收作業(yè)質(zhì)量難保證。種植戶對于機(jī)收損失問題常常“不問不顧”。“三夏”搶收農(nóng)時短，機(jī)具緊張，不少種植戶只求收到干凈清爽的麥子(不要在揚(yáng)場清選)，收割機(jī)清選風(fēng)量較大，盡可能把雜余吹得干干凈凈，部分谷粒隨小秸稈雜余被風(fēng)吹到田間去，造成脫粒清選損失加大。
 
　　二是機(jī)手追求較高的作業(yè)效率和較大的利益回報。機(jī)收作業(yè)時，機(jī)手會盡可能地開足馬力用“行走”擋位高速作業(yè)，而收割機(jī)用“行走”擋位高速作業(yè)是明令禁止的。據(jù)了解，自走履帶式聯(lián)合收割機(jī)分別用“標(biāo)準(zhǔn)”擋位和“行走”擋位作業(yè)，作業(yè)面積每天可相差15-20畝，機(jī)手每天創(chuàng)收懸殊達(dá)千元左右。
 
　　三是不能保證小麥適期收割。小麥機(jī)收宜在蠟熟末期至完熟初期進(jìn)行，此時產(chǎn)量最高，品質(zhì)最好。但是由于農(nóng)時短，裝備緊等客觀原因，以及主觀上部分農(nóng)戶缺少對天氣和農(nóng)作物長勢的細(xì)致觀察，對農(nóng)業(yè)部門發(fā)布的相關(guān)信息也置之不理，直接導(dǎo)致部分農(nóng)戶不能保證適期收割，麥穗折斷和田間掉粒問題顯著增加，此時機(jī)收收割機(jī)撥禾輪的沖擊，造成割臺損失加大，機(jī)損率就很難得到保障。
 
　　對此，提出如下建議：
 
　　1.加強(qiáng)農(nóng)機(jī)裝備的試驗示范推廣工作，確保使用的機(jī)具適應(yīng)當(dāng)?shù)刈魑?、土壤和氣候條件。
 
　　2.加強(qiáng)對機(jī)手的培訓(xùn)和技術(shù)支持，提高機(jī)手的農(nóng)業(yè)機(jī)械使用維護(hù)技能，減少因機(jī)器操作不當(dāng)造成的機(jī)器故障和損失。
 
　　3.積極調(diào)配農(nóng)機(jī)裝備，引導(dǎo)農(nóng)戶和機(jī)手因地制宜選擇收獲時機(jī)、合適機(jī)具和機(jī)收方式，保證適期收獲，千方百計減少機(jī)收損失。
 
　　4.加強(qiáng)農(nóng)機(jī)維修和保養(yǎng)服務(wù)指導(dǎo)工作，建立農(nóng)機(jī)維修站點(diǎn)和配件供應(yīng)網(wǎng)絡(luò)，方便農(nóng)民及時得到機(jī)器的維修和更換配件服務(wù)。
