Pot culture experiments were carried out on the black soil from Harbin and the paichiang soil from Hwachuan Hsien,both of Heilungkiang Province.Application of superphosphate alone increased the yield of wheat in the paichiang soil but not in the black soil.Combined application of nitrogenous and phosphatic fertilizers increased the yield of wheat in both soils. Uptakes of phosphorus by wheat at various stages of plant growth were examined by tracing technique.In the black soil,addition of ammonium sulphate encouraged the uptake of soil phosphorus by plant,while in the paichiang soil the main supply of phos- phorus to plant was from superphosphate.

1.盆栽条件下黑土单施磷肥使小麦减产8.69—15.51%。磷肥和氮肥配合施用可提高磷肥肥效,小麦产量增加了184.44—314.58%。单施氮肥增产224.37—289.54%。白浆土单施磷肥可使小麦增产7.95—38.25%。单施氮肥增产149.83—160.26%,而磷肥与氮肥配合施用增产达176.85—429.91%。2.小麦产量的提高与植株总磷量,特别是与吸收肥料磷量占全磷的比例有密切关系,植株中肥料磷增加,产量亦相应提高。黑土中有效磷合量为7.83—13.11毫克/100克土;白浆土为1.46—4.99毫克/100克土。因此,黑土上小麦吸收土壤磷素较多,肥料磷较少;白浆土上则相反。3.小麦植株含氮量随着含磷量而相应提高。黑土氮磷配合施用,可使小麦对肥料磷利用率提高4.45—21.48%,土壤磷利用率提高1.61—4.99%。白浆土氮磷配合施用,肥料磷利用率提高17.69—28.89%,土壤磷利用率提高0.74—1.02%。

When nitrogenous fertilizers were applied as base fertilizer, the rate of utilization of (15NH4)2SO4 and 15NH4HCO3 by rape plants ( Brassica napu S · L ) planted in pots were 58.66% and 55.94%, respectively. Their rate of utilization increased to 63.83% and 59.10% respectively when the base fertilizers were mixed with 3% ASU. Furthermore, by applying ASU to the base fertilizers, the ratio of nitrogen in seeds increased from 67.88% to 74.52% for(15NH4)2SO4 and from 66.13% to 73.54% for 15NH4HCO3, while...

When 15NH4HCO3 was top-dressed at shooting stage and flowering stage, the ratio of utilization of the fertilizer was only 27.40%.

在盆栽条件下,以等量不同种类氮肥作基肥施用于油菜,硫铵的利用率为58.66%,碳铵为55.94%。在添加ASU后,利用率分别为63.83%和59.10%,比不加ASU的提高5.17%和3.16%.植株中基肥氮在籽粒中的比率,硫铵的为67.88%,碳铵的为66.13%;添加ASU后,分别提高到74.52%和73.54%,表明油菜所吸收的氮大部分用来形成籽粒;同时在基肥中添加ASU后叶片中的氮素比率相对减少,说明ASU有利于氮向籽粒运转,碳铵尤为明显.用15N-碳铵作追肥施于油菜表土层,其利用率为27.40%,仅为基肥的50%左右,说明碳铵作基肥深施显著优于追肥。

In long-term fertilizer trials with applications of phosphatic fertilizer and nitrogenous fertilizer on oil-tea camellia, yield was increased by 201%. Phosphatic fertilizer and nitrogenous fertilizer supplemented with oil-tea seed cake gave better result than any other treatments and increased the yield by 239-287%. Application of ground rock phosphate or oil-tea seed cake singly had no effect, and application of nitrogen fertilizer singly considerably stimulated vegetative growth, but it had only...

In long-term fertilizer trials with applications of phosphatic fertilizer and nitrogenous fertilizer on oil-tea camellia, yield was increased by 201%. Phosphatic fertilizer and nitrogenous fertilizer supplemented with oil-tea seed cake gave better result than any other treatments and increased the yield by 239-287%. Application of ground rock phosphate or oil-tea seed cake singly had no effect, and application of nitrogen fertilizer singly considerably stimulated vegetative growth, but it had only a little effect on yield. Ground rock phosphate was found to be an effective fertilizer for oil-tea camellia.Experiments proved that rational application of fertilizers would bring high economic benefit. The profit per mu was 51. 23-98.29 yuan, and there was the return of 2.61-6.53 yuan at the cost of 1 yuan.

经多年试验表明,磷肥和氮肥配合使用,油茶增产极显著(2.0倍),在氮磷基础上配施茶饼,效果更好(2.4~2.9倍),单独施氮肥营养生长效果好,但增产幅度较小;单施茶讲或磷肥则无效;钙镁磷肥、磷矿粉、过磷酸钙3种磷肥分别与尿素、茶讲配施均有极显著的增产效果。试验还表明,磷矿粉对油茶是有效的,其效果与钙镁磷肥及过磷酸钙同。大面积施肥试验表明,油茶合理施肥能显著提高经济效益,每亩获利51.23~98.29元,每元成本获利2.61~6.53元。
