【實用技術(shù)】燕麥種子處理與播種的注意事項

導(dǎo)讀：燕麥適宜在高寒濕潤地區(qū)生長，對溫度的要求較低，種子發(fā)芽的最低溫度為3℃-4℃。

　　【農(nóng)機網(wǎng) 科技創(chuàng)新】 1、種子處理
 
　　挑選籽粒飽滿的種子，保證種子的純凈度和整齊度。播前，選擇無風(fēng)晴天，將種子暴曬2-3天。增強種皮的通氣性和適水性，提高種子的生活力和發(fā)芽率，殺滅種皮的細菌，減輕某些病害的發(fā)生。
 
　　2、播期
 
　　燕麥適宜在高寒濕潤地區(qū)生長，對溫度的要求較低，種子發(fā)芽的最低溫度為3℃-4℃。燕麥對高溫較敏感，在抽穗、開花、灌漿期遇到高溫，則影響結(jié)籽。播種期很長，具體播種時期可視具體生產(chǎn)條件而定。
 
　　3、播量和播深
 
　　單播150-225 kg/hm2，混播90-155 kg/hm2。草用種植量可大些，種用則要小些。干旱陽坡地、山坡地或高寒地區(qū)，種植量可適當加大。播種深度一般為3-4 cm，土壤墑情差時，可適當播深至5-6 cm，播后鎮(zhèn)壓。
