绿肥是我场农业生产的重要肥源。早期我场是以麦田套种苜蓿。六十年代推广春播小油菜作稻田绿肥,由于插秧提早,春播小油菜的面积逐年缩小。小麦套种的苜蓿共生期隐蔽严重,麦后淌水不适时,管理粗放,保苗困难。七十年代初试验夏播小油菜、箭筈豌豆取得成效,经过示范推广,发展为数千亩的大面积生产,使我场绿肥种植从套种发展到复种,从春播发展到夏播,从解决水田绿肥发展到解决早地绿肥。实践证明,夏播绿肥生产简便,产草量大,成本低,肥效高,不但促进粮食生产,也利于蜂群越冬和畜牧业的发展。
Green manure is an important source of fertilizer for agricultural production in our country. Early my field is wheat field intercropping alfalfa. Sixty time to promote spring sowing small rapeseed green manure, due to early planting, spring sowing small rapeseed area decreases year by year. Interplanting alfalfa intercropping wheat serious covert, malt drip water illicit, extensive management, seedling difficulties. In the early seventies of the trial summer sowing rape, arrowhead pea achieved success, after demonstration and promotion, the development of thousands of acres of large-scale production, so that my field of green manure from the interplanted to the development of cropping, from sowing to summer sowing, from the settlement Development of paddy green manure to solve the green manure early. Practice has proved that summer sowing green manure production is simple, large amount of grass, low cost, high efficiency, not only to promote food production, but also conducive to the development of bee colony and animal husbandry.
