Field experiment was carried out at the south part of the Loess Plateau, to study the effects of different soil surface mulching methods and N rate on winter wheat growth and nitrogen accumulation and translocation in plant in different years. The re...

The influences of nitrogen and phosphorus nutrients on seed yield and quality of maize were studied by using a split plot experiment in the rainfed lands of the Loess Plateau. The results show that crude protein, crude fat, lysine contents, seed bulk...

A field experiment was conducted in Gaocheng County, Hebei Province during 2005-2006. Four winter wheat cultivars, TM1, SM12, SX531 and SX828, were used as experimental materials. The growing area for each cultivar was 1 ha, divided into three subplo...

Plant N nutrition is important for plant metabolisms and its resistance to plant diseases. Two rice varieties with different resistance to rice blast, Huangkenuo(HKN) and Hexi-41 (HX41), were used to investigate the effect of nitrogen fertilizer rate...

Both aluminum (Al)-induced secretion of organic acids from roots and the immobilization of Al with phosphorus in roots were investigated to elucidate Al-resistant mechanisms in rye (Secale cereale L.，cv. Win and King). It was sh...

The long-term alternate leaching aerobic incubation is the most important method for evaluating soil N supplying capacity. Initial mineral N(N_min), extractable total soluble N and soluble organic nitrogen(SON), mineral N(MNL=NO₃...

Field in-situ trials were carried out to study the effects of swine manure application on phosphorous losses from different farmlands under rainfall simulation in Dianchi watershed of Yunnan province. The results show that with the increase of applyi...

The effects of NaCl stress on root vigor, H⁺-ATPase activities of plasma membrane and tonoplast membrane, H⁺-PPase activities of tonoplast membrane, Ca²⁺-ATPase activities of plasma membrane and tonoplast membrane, pl...

Greenhouse tomato experiment was conducted in Shouguang, Shandong province in order to investigate the effects of irrigation strategies and N sidedressing on fruit yield and N utilization in greenhouse tomato. Compared with conventional fertilization...

Cucumber plants grew in nutrient solution under different NO₃^– concentration for 7 d at hydroponic system. The changes of photosynthesis rate and related parameters in cucumber seedling leaves were studied in order to reveal th...

A pot culture was conducted to study the effect of four B levels from B deficiency to excessive B on seed yield and quality of double low rapeseed cv. Huashuang 4 (HS-4), using double high rapeseed cv. Zhongyou 821 (ZY-821) as a control. The f...

Changes of endogenous polyamines and hormone under different NO₃^- stress were studied in cucumber seedlings growing by solution culture method. Results showed that, after treating with 56 and 98 mmol/L NO₃^...

This paper studied the effects of different anion species（Cl^-, SO₄^2-）, concentrations and Cd level on Cd absorption of spinach(Spinacia oleracea）through pot experiment. The results showed that the Cd accumul...

The effects of floating nursing seedling in nutrient water-bed (FNS) on physiological and biochemical characteristics of cotton seedlings and the morphological characteristics of transplants in the field were studied using Nongza 66 as the tes...

To understand the translocation and distribution regularity of photosynthates in cotton leaves under drought stress, an experiment was performed under a water proof canopy with different levels of soil moisture. The translocation and distribution of ...

Field experiment was conducted to explore the effects of foliar-spraying prohexadione calcium on the physiological characteristics and pod yield of peanut (Arachis hypogaea L.). Results showed that chlorophyll contents and thickness of leaves ...

Adopting the method of foliar application, the experiment was conducted to investigate the effect of Mn and B on herbage yield and quality of alfalfa. The results showed that foliar application of Mn and B could increase the herbage yield of alfalfa....

To find out the law of absorption, utilization and storage of nitrogen in kiwifruit tree, and to provide facts for nitrogen nutrition analysis and for reasonable fertilizing amounts and the their application periods, a field experiment were conducted...

Uptake of pyrene from soils by clover (Trifolium subterraneum L.) and capsicum (Capsicum annuum L.) in the presence of arbuscular mycorrhizae (AM) fungi was investigated using a greenhouse study. The impacts of AM on phytoremedia...

Controlled-release fertilizer (CRF) has emerged as a potential approach to solving the problems associated with the application of conventional fertilizers. It can improve fertilizer use efficiency, reduce application times and environment pollution....

Phosphorus (P) is one of the most important macronutrient elements for plant growth. High residual P in greenhouse soils was frequently found because P is relatively insoluble and has a long residence time in the soil. In order to find an optimal lev...

To test remediation effects of balanced fertilization on a paddy soil with long-term K-deficiency, a pot experiment has been being carried out since April, 2005 with five fertilization treatments (NPK, NPKSi, NPKOM, NPhK and NPhKOM）. The results sho...
