我场1961年从青海引进小油菜试种,经过多年试验、示范、推广。现已从小面积种植,发展到大面积生产;从单一种植,发展到复茬种植;从一年种一茬,发展到一年种两茬;从解决绿肥生产问题,发展到解决油料生产问题。通过几年的生产实践证明,小油菜是一个适宜我区土壤、气候条件种植的油料、绿肥作物。它既可解决粮、油争地的矛盾,作为水稻前茬和小麦后茬的油料作物种植,又能解决稻、旱田绿肥问题,作为插秧稻的当年前茬绿肥和麦收后复种作第二年旱田绿肥,或作卷秧及早期插秧的绿肥茬。小油菜是无限花序,早春开花,花期长,有利于早期放蜂;秋季种植有利于蜂群越冬,促进养蜂业的发展。小油菜的茎秆,经粉碎后做猪饲料,适口性好,增加了粗饲料来源,有利于养猪事业的发展。现将我场
My field 1961 introduced from Qinghai small rape try, after many years of experiments, demonstration, promotion. Now from a small area of ?? planted to large-scale production; from a single plant, the development of stubble planting; from a year of crop stubble, the development of two crops a year; from solving green manure production problems, development to solve the problem of oil production. After several years of production practice has proved that rapeseed is a suitable soil for our region, climatic conditions planted oil, green manure crops. It can not only solve the contradiction between grain and oil fields, but also can be used as oil crop planting in the fields of rice stubble and wheat stubble. It can also solve the problem of green manures in paddy field and dry land. Dry land green manures, or for the early spring and volume transplanting green manure. Small rapeseed is inflorescence, flowering in early spring, long flowering period is conducive to the early release of bee; autumn planting is conducive to the colony overwintering, and promote the development of beekeeping. Small rape stalk, after crushing pig feed, palatability is good, increasing the source of roughage, is conducive to the development of pig breeding. Now my field
