農(nóng)業(yè)部發(fā)布2017年青貯玉米生產(chǎn)技術指導意見

　　青貯玉米是指在佳收獲期將包括果穗在內的玉米地上部植株收獲，經(jīng)過整株切碎、加工或貯藏發(fā)酵，并以一定比例配置成用以飼喂以牛、羊為主的草食家畜的飼料作物。《全國種植業(yè)結構調整規(guī)劃(2016-2020年)》提出，按照以養(yǎng)帶種、以種促養(yǎng)的原則，因地制宜發(fā)展青貯玉米，到2020年達到2500萬畝。為充分發(fā)揮青貯玉米在種養(yǎng)結合等方面的優(yōu)勢，助力玉米種植結構調整和農(nóng)業(yè)供給側結構性改革，制定2017年青貯玉米生產(chǎn)技術指導意見如下。
 
　　一是因地制宜，科學布局。按照資源稟賦和種養(yǎng)結合的要求，突出優(yōu)勢區(qū)域，科學安排布局，結合當?shù)匦竽翗I(yè)發(fā)展規(guī)模和種植習慣，鼓勵有條件的種植大戶、家庭農(nóng)場、農(nóng)民合作社，發(fā)展訂單生產(chǎn)、規(guī)模化種植，做到以養(yǎng)帶種、以種促養(yǎng)。
 
　　二是優(yōu)選良種，合理搭配。因地制宜選擇適宜當?shù)胤N植的成熟期適宜、生物產(chǎn)量高、干物質含量高、青貯品質優(yōu)、持綠性好、耐密抗倒、抗病抗逆、適應性廣的專用型或糧飼兼用型青貯玉米品種。根據(jù)養(yǎng)殖及市場需要，結合當?shù)刈匀粴夂蛱攸c，合理安排春播、夏播或一年兩茬的青貯玉米生產(chǎn)，做到播期合理、熟期搭配。。
 
　　三是精量播種，適當增密。選用發(fā)芽勢強、活力高、適宜單粒精播的高質量種子，通過單粒精量播種機進行單粒精量播種，嚴把播種質量關，確保一播全苗，提高群體整齊度。種植密度可比普通籽粒玉米品種適當增加，一般畝增500株左右，畝保苗5000株左右。規(guī)?；N植時，科學制定種植計劃，分期播種，以便實現(xiàn)適期分批收獲。
 
　　四是肥水運籌，加強田管。根據(jù)土壤肥力、產(chǎn)量目標及品種需肥特點等，科學施用基肥、種肥和追肥，提高青貯產(chǎn)量。推薦雨養(yǎng)旱作種植，關鍵生育期遭遇干旱可適度進行節(jié)水灌溉。注意防治玉米螟等病蟲害，提高青貯品質。
 
　　五是適期機收，穩(wěn)產(chǎn)保質。專用青貯玉米的適收獲期為乳熟末期至蠟熟初期，全株含水率平均為65%-70%，干物質含量達到30%以上。如以籽粒乳線位置作為判別標準，乳線處于1/2至1/3時適期機械收割。收獲過早，則植株含水量高、干物質低；收獲過晚，則酸性洗滌纖維增高、消化吸收率降低，同時因水分降低，不易壓緊，導致青貯發(fā)霉變質，品質下降等。
 
　　六是及時青貯，密封備用。及時、高質量地進行青貯，是制作青貯飼料的重要環(huán)節(jié)。收割后及時運到加工地點，盡可能做到當天收割當天加工貯存。根據(jù)實際情況，因地制宜選擇青貯窖、青貯壕、青貯塔、青貯裹包等合適的青貯方式。將青貯玉米秸稈切碎小于2厘米、籽粒全部壓碎，及時裝填，均勻壓實，要嚴密封窖，防止漏水漏氣。密閉發(fā)酵6-7周，開窖質檢合格后即可飼喂家畜。
