With titanium-bearing blast furnace slag, ammonium sulfate, citric acid and potassium carbonate as raw materials to produce foliar fertilizer and Ca-S-Si compound fertilizer by means of heating process for the first time, which improved the solubility of the slag and converted the nutritional elements into such ones which are prone to be absorbed by plants. The effects of process conditions on dissolution rate of titanium were mainly analyzed through the orthogonal experiment. The results showed that the optimum synthesis process conditions of foliar fertilizer from the slag were 360 ℃ for 35 min, the mass ratio of ammonium sulfate and titanium-bearing blast furnace slag was 8：1. Under these conditions more than 80% of iron, titanium, magnesium and part of silicon in titanium-bearing blast furnace slag converted into water-soluble substances and existing in foliar fertilizer. foliar fertilizer contained nitrogen, sulfur, potassium, iron, titanium, magnesium and silicon, and pH value of foliar fertilizer was 6. Ca-S-Si compound fertilizer mainly contained calcium silicate and calcium sulfate, which existed in the form of citric acid-soluble substance and slightly soluble substance, respectively.

The experiment aimed to investigate foliar fertilizer application effects on amino acid content of Indigofera leaves. lndigofera arrecta was planted in plots during both rainy and dry seasons. foliar fertilizer concentrations consisted of 10 g, 20 g, 30 g, 40 g and 50 g, which solved in 10 L solvent were appIied on sixteen individual plants per plot, The fertilizer was applied 4 times during vegetative growing period. Block randomized design with 3 replications was used in this experiment. The foliar fertilizer containing 20%-22% N （N total）, 15%-16% P （P205）, 15%-16% K, 1.5% Mg, 1% Ca, 1% Fe, 1.42% Zn, 0.53% Cu, 0.88% Mo, 0.53% B and growth hormone 0.025% indole acetic acid （1AA） and giberelic acid （GA） was applied. Samples of each plot were composited leaves from 3 harvest times. The result showed that the foliar fertilizer did not affect aspartic acid, seriue, histidine, threonine, tyrosine, valine, methionine, iso-leusine and leusine content oflndigofera leave. foliar fertilizer application up to 50 g/10 L resulted in higher （P 〈 0.05） glutamate acid, glysine, arginine, alanine, proline and lysine than those of other fertilizer levels.

Effects of Amino Acid foliar fertilizer on the Yield and Quality of Different Vegetables

引用

Agricultural Science & Technology 2018年第6期19卷 10-15页

作者： SUN Mei SUN Geng MA Hao-liu LUO Zun-chang LIU Jie Hunan Soil and fertilizer Research Institute Changsha 410125 PRC College of Resources and Environment Hunan Agricultural University Changsha 410128 PRC

In order to explore the effects of amino acid foliar fertilizer on the yield and quality of different vegetables, we tested the spraying of an amino acid foliar fertilizer(Wanfeng 2) onto the leaves of cucumbers, eggplants and water spinach through contrast experiment in a greenhouse. The results showed that the yield increments of amino acid foliar fertilizer treatments in cucumbers, eggplants and water spinach were 11.57%, 4.43% and 12.41% respectively, and the output-input ratios were 64.52 ∶ 1, 53.31 ∶ 1 and 55.14 ∶ 1 respectively. Amino acid foliar fertilizer can influence the quality of greenhouse vegetables. The total sugar content of the cucumbers, eggplants, and water spinach significantly increased by 12.00%, 22.30%and 12.10% respectively. The vitamin C content increased by 4.76%, 24.80%, and10.90% respectively compared with the control. In conclusion, the spraying of amino acid foliar fertilizer could improve the yield and the nutritive quality of vegetables such as cucumbers, eggplants and water spinach.

The burning of agricultural waste is a major cause of environmental *** this study,we sought to prepare biochar from agricultural waste as a source material for the preparation of carbon nanoparticles(CNPs).Surface morphology,hydrodynamic particle size,and purity and crystallinity of CNPs were extensively investigated using transmission electron microscopy(TEM),zeta sizing,and X-ray diffraction(XRD)spectroscopy,*** CNPs were subsequently immersed in a solution of potassium nitrate(KNO_(3))to prepare a CNPs/NK nanocomposite(CNPs loaded with nitrogen(N)and potassium(K))as a nanocomposite fertilizer for common bean(Phaseolus vulgaris L.).The CNPs/NK nanocomposite was sprayed as a foliar fertilizer at 0,10,20,30,and 40 mg L^(-1) on common bean plants 25 d after sowing on a farm in Shebin El-Kom,El-Monifia,*** growth,yield,and quality of common bean were investigated during two successive growing seasons(2017 and 2018).The highest seed yields of 2.04 and 2.01 t ha^(-1) and the highest values of growth parameters including plant height of 61.5 and 59.2 cm,number of leaves per plant of 35 and 35,number of flowers per plant of 83.3 and 82.7,and plant fresh weight of 148.7 and 152.8 g plant^(-1) were obtained when using the CNPs/NK nanocomposite at a concentration of 20 mg L^(-1) during the 2017 and 2018 growing seasons,respectively.

At present, international domestic afforests to the city with flowers and plants' demand quantity and the quality all unceasingly is increasing, the flowers and plants variety renewal speed unceasingly speeds up, but the city natural soil fertility was barren greatly day by day has actually hindered the development which the city afforested. Provides the nutrition through the fertilizer which the growth needs for the flowers becomes sharing solution this question the quite direct feasible method. The determination appropriate flowers and plants fertilizer is suitable for the flowers large-scale planter work to appear importantly. The flowers planter work also set the new request to the modernized fertilizer production at the same time.This experiment choose the local flowers and plants planter on the cultivation several kind of flowers and plants to take the sample with emphasis, to have certain representative in herbaceous flowers and the perennial flower carries as the pattern plant. Carries on the quota to in the growth flowers to apply fertilizer, coordinates the certain experimental method to come to the experimental flowers on the observation and the analysis determination. Chose in the national multitudinous flowers fertilizer product joins the high tech ingredient Sign JI' AO fertilizer to take experimental fat carried on the effect planter experiment. Reflected uses or apply fertilizer with the flowers and plants field production relations, like the fertilizer effectiveness experiment, the natural, quality aspect to the flowers situation.The experiment under the different growth condition to plant element the in N, P, K, Fe, Mn content change carries on the analysis, summarizes was measured the flowers need the nutrient rule in the different periods of growth, obtains reasonably applies fertilizer the plan is: Saint JI' AO foliar fertilize spurts executes to the herbaceous flowers' optimization grows obviously is effective.
