摘要
为探求青海高寒地区地膜覆盖和磷肥配施对荷兰豆增产与品质影响.设置不覆膜(M0)、普通地膜(M1)、降解地膜(M2)3 个覆膜水平,0(P0)、50(P1)、l00(P2)、150(P3)、200(P4)P2O5kg/hm25 个施磷水平进行二因素随机区组试验.结果表明:荷兰豆覆膜配施磷肥具有显著促生作用,较不覆膜处理,干物质积累量提高了 12.63％～52.64％,抽蔓、开花结荚期干物质积累量M2＞M1＞M0;株高增加7.69％～35.29％;产量最高的是处理M2P3,为1 193.15 kg/667m2,较M0P3、M0P0提高18.86％、19.78％,覆膜配施磷肥促进蛋白质合成,但是降低了 Vc含量和可溶性糖含量,均表现为M0＞M1＞M2.
Abstract
To explore the effects of plastic film covering and phosphorus fertilizer application on the yield and quality of Snow pea in high-altitude areas of Qinghai.Three levels of plastic film covering have been set,including non plastic film(M0),ordinary plastic film(M1),and degradable plastic film(M2).There were total of 5 phosphorus application levels:0(P0),50(P1),100(P2),150(P3),and 200(P4)P2O5 kg/hm2.A two factor randomized block trial was conducted.The results showed that mulching with phosphor-us fertilizer significantly promoted the growth and development of Snow pea.Compared with the non mulching treatment,the dry matter accumulation increased by 12.63％to 52.64％,and the dry matter accumulation during the heading period,flowering-poding phase,and picking period was M2＞M1＞M0;Plant height in-creased by 7.69％to 35.29％;The M2P3 treatment had the highest yield of 1 193.15 kg/667m2,which was 18.86％and 19.78％％higher than M0P3 and M0P0,respectively.Film mulching combined with phosphorus fertil-izer promoted protein synthesis,but reduced Vc content and soluble sugar content,both showing M0＞M1＞M2.
