【摘要】 以上海郊区主要代表性土壤为试验点,结合网室模拟试验,研究了冬作经济绿肥在上海地区的适种性,通过施肥对比试捡,种子不同处理方式、不同的栽培播种模式等方法研究了冬作经济绿肥的主要高产栽培技术,研究结果表明:紫云英、小豌豆、蚕豆和黑麦草是上海地区较为理想的冬作经济绿肥,可获得较高的鲜草产量。光苕、毛苕、箭豌虽能适应上海地区的气候、土壤等条件,但经济性状较差,不能供人食用,作饲料其养分低、适口性差。只能作一般的有机肥肥源;用河泥普钙拌种能提高金花菜出苗率提高鲜草产量,适量施用肥料能提高提高绿肥鲜草产量,不同类型品种混播能提高光能利用率、提高绿肥鲜草产量。为上海地区绿肥高产栽培技术提供了科学依据。更多还原

【Abstract】 Regard main representative soil in the suburb of Shanghai as the trial spot,combine the simulated test of network room,has studied the suitability for planting economic green manure in winter in Shanghai,through the compare trial applying fertilizer with different seed type and different culture sow mode to study technique of the Winter plant with economic,green manure and high yield in Shanghai,the result of study shows,Chinese milk vetch,small pea,broad bean and black whestgrass are compar- atively ideal plants suit for winter plant with economic green manure in Shanghai,can obtain the higher fresh output of grass. Though Mere Shao,Shao Mao,arrow pea can meet climate,soil condition of Shanghai,but the economic properties are rela- tively bad,can not for people to eat,nutrient of fodder is low,not agreeable to the taste which only can be made for the gen- eral organic fertile source of manure;We can improve the emergence rate of the bur clover and raise the delicious output of grass dressing seed with the general calcium of river silt,and can improve the output of fresh grass green manure in right a- mount using the fertilizer,can improve the utilization ratio of light and raise the fresh output of grass of green manure to sow energy with different kinds of varieties mixing.The scientific basis for fertile cultivation technique of green manure in Shanghai have been offered in this paper.更多还原
