摘要
为筛选适宜贵州省低磷黄壤土上生长利用的绿肥种质资源,选取国外引进绿肥种质资源13份,种植于低磷黄壤中,研究其营养期生长速率,盛花期主要农艺性状、养分积累与供应,花穗期,留种量等。结果表明,全氮、全磷、全钾总养分积累量居前三的种质资源为HZMC1374箭筈豌豆(19.46 g/株)、HZMC1349箭筈豌豆(18.50 g/株)、HZMC1300白芥(15.54 g/株),养分截获与供应能力较高。对于最佳还田利用时间,HZMC1442白芥、HZMC1300白芥、HZMC1298春山芥、HZMC1299春油菜为3月1日至30日,HZMC1539艾菊叶法色草、HZMC1334毛叶苕子、HZMC1302毛叶苕子,为4月1日至5月6日,HZMC1446豌豆、HZMC1374箭筈豌豆为4月14日至5月4日,HZMC1349箭筈豌豆、HZMC1367箭筈豌豆、HZMC1353箭筈豌豆为4月29日至5月15日,HZMYZW26香青兰为6月3日至21日。对于留种量,HZMC1349箭筈豌豆、HZMC1299春油菜、HZMC1300白芥、HZMC1367箭筈豌豆、HZMC1539艾菊叶法色草留种量较高,分别为607.13、467.93、346.40、276.47、256.93 kg/hm^(2)。
To screen green manure germplasm resources that are suitable for growth in low-phosphorus yellow soil of Guizhou Province,13 green manure germplasm resources introduced from abroad were planted in low-phosphorus yellow soil,and the growth rate at vegetative growth stage,main agronomic characters,nutrient accumulation and supply at full-bloom stage,flowering period and seed retention were analyzed.The results showed that the top three green manure germplasm resources of total nutrient content of total N,P and K were HZMC1374(Vicia sativa L.),HZMC1349(Vicia sativa L.)and HZMC1300(Sinapis alba)with the total nutrient contents of 19.46,18.50 and 15.54 g/plant,and their nutrient interception and supply capacity were higher.In terms of optimal utilization time to return to the field,HZMC1442(Sinapis alba),HZMC1300,HZMC1298(scurvy grass)and HZMC1299(spring rapeseed)were returned to the fields from March 1 to March 30;HZMC1539(Phacelia tanacetifolia),HZMC1334(Vicia villosa),HZMC1302(Vicia villosa)were returned to the field from April 1 to May 6;HZMC1446(pea)and HZMC1374 were returned to the field from April 14 to May 4;HZMC1349,HZMC1367(Vicia sativa L.)and HZMC1353(Vicia sativa L.)were returned to the field from April 29 to May 15;HZMYZW26(Dracocephalum moldovica Linn.)was returned to the field from June 3 to June21.The seed yields of HZMC1349,HZMC1299,HZMC1300,HZMC1367 and HZMC1539 were higher,which were 607.13,467.93,346.40,276.47 and 256.93 kg/ha respectively.
