磷及有机肥对白菜型冬油菜产量及品质的影响
Effects of phosphorus and manure on canola growth period, grain yield and quality
摘要
Abstract
A field experiment with the split-split block design was carried out to study the effects of applying manure and phosphorus on canola growth period ,grain yield and quality .The main treatments were manure (M) and no manure (M0 ) .Sub-split treatments were four phosphorus application rates at 0 ,75 ,150 and 225 (P2O5 ) kg·hm - 2 (P0 ,P75 , P150 and P225 ,respectively) .Sub-sub-split treatments were three main planting canola varieties in Tianshui region includ-ing Tianyou 8 ,Tianyou 07302 and Tianyou 191 (V1 ,V2 and V3 ) .The results showed that application of manure pro-longed canola reproductive growth period by 2 days ,while it had not evident effect on vegetative growth and total growth periods .However ,application of phosphorus can shorten canola vegetative growth period by 3 to 5 days ,prolonged repro-ductive growth period by 6 to 15 days ,and eventually prolonged canola total growth period by 6 ~ 8 days .Application of manure increased canola yield by 13 .32% ,whereas it had not significant effect on canola seed quality compared with M0 treatment .Application of phosphorus had significant effects on rape yield and quality .Phosphorus significantly increased canola yield and erucic acid content .The changing trend was firstly increased and then became decreased with the in -crease of phosphorus application rates .Compared to the control treatment (P0 ) ,canola yield and erucic acid content by P75 ,P150 and P225 treatments were increased by 94 .01% ,137 .63% ,and 122 .64% ,and 1 .98% ,3 .37% ,and 1 .70% ,respectively .Grain oil content was always increased with the increase of phosphorus application rates .The highest oil content was reached by P225 treatment ,increased by 3 .61% compared with the control treatment (P0 ) ,but no significant difference was found between P150 treatment and P225 treatment .On the contrary ,application of phosphorus significantly decreased grain protein and glucosinolate content .The more phosphorus was applied ,the more grain protein and glucosinolate content went declined ,reduced by 4 .27% and 2 .25% by the P225 treatment from the control treatment (P0 ) .关键词
