浙江省滨海盐土及青紫泥上油菜锌肥效应及施用方法研究

土壤分析表明，浙江省土壤缺锌面积约占耕地面积的５０％左右，尤其是滨海盐土，土壤中的有效锌含量平均为０．８７×１０－６．本研究证明油菜施锌肥有一定的增产效果，其肥效与土壤有效锌含量和施锌方法有关，化学锌肥与有机肥料混合施用，可显著提高油菜施用锌肥的增产效果。     

Foliar application of distillery-spent wash as a liquid fertilizer for betterment of growth ofSorghum vulgare andCajanus cajan

The distillery spent wash contained all necessary elements and biofertilizer microbes (Rhizobia, Azospirilla, Azotobacter, and phosphobacteria) to support the growth of plants. Application of the spent wash, as it is without dilution, did not cause deformities and derangement of plant metabolism. The successful use of distillery spent wash as a liquid fertilizer for augmenting crop productivity in C3 and C4 plants has been demonstrated.     

Crystallization of metastable monoclinic carnallite,KCl·MgCl2·6H2O: missing structural link in the carnallite family

During evaporation of natural and synthetic K–Mg–Cl brines, the formation of almost square plate‐like crystals of potassium carnallite (potassium chloride magnesium dichloride hexahydrate) was observed. A single‐crystal structure analysis revealed a monoclinic cell [a = 9.251 (2), b = 9.516 (2), c = 13.217 (4) Å, β = 90.06 (2)° and space group C2/c]. The structure is isomorphous with other carnallite‐type compounds, such as NH₄Cl·MgCl₂·6H₂O. Until now, natural and synthetic carnallite, KCl·MgCl₂·6H₂O, was only known in its orthorhombic form [a = 16.0780 (3), b = 22.3850 (5), c = 9.5422 (2) Å and space group Pnna].     

三溴偶氮胂光度法测定磷肥中稀土总量

本文提出用三溴偶氮胂显色剂在ＥＤＴＡ－Ｚｎ存在下酸性介质中光度测定磷肥中稀土总量的方法。对三种磷肥样品实测结果表明，本法较简便、灵敏度高、选择性好，与ＰＭＢＰ－苯萃取分离—光度法测定结果基本一致。     

Effects of potassium feldspar on slagging and fluxing in phosphorus produced via electric furnace

In this study, thermodynamic calculations were conducted to investigate K-feldspar fluxing yellow phosphorus produced via an electric furnace. The results demonstrated that the reaction temperature of K-feldspar as a flux was lower than that during the traditional process. The characteristic temperatures of silica-CaO and potassium feldspar-CaO systems under different mass ratios of SiO₂/CaO were measured according to the CaO-substituting decomposition products of phosphorus; the results showed that the temperature of the silica-CaO system was higher, 96.2–114.3°C, compared to the potassium feldspar-CaO system under the same conditions. These results indicate that K-feldspar as a flux in a phosphorus furnace can save energy and reduce cost. X-ray diffraction (XRD) analysis further revealed that a complex transition phase of silicates and aluminosilicates was accompanied by a conversion reaction of the silica-CaO and potassium feldspar-CaO systems, and that K₂O capable of co-producing potash fertilizer escaped as a gas through the collection equipment.

Ammoniated Products of Aspes Wood Oxidation

A high-molecular-weight product containing 10.9% organically bound N and 8.92% COOH groups is isolated after oxidation of aspen chips with an ammonia solution of ammonium persulphate. The product, which has 25% readily assimulated N in the ammonium and amide forms, was proposed as a N-containing organo-mineral fertilizer.     

高分子缓释化肥的缓释性能研究

对一种含氮、磷、钾三种营养元素的高分子型缓释化肥—MSF,分别在去离子水及土壤溶液中进行了养分释放规律的研究.实验结果显示:在120天内,MSF在去离子水中失重不到40%,氮、磷、钾三种营养元素也只分别溶出了30%,28%和38%;而在土壤溶液中,在120天内,MSF失重接近100%,氮,磷,钾三种营养元素基本完全转化为小分子物质溶入土壤溶液中.实验结果表明:(1)MSF初期溶出率较低,能显著的减少淋溶损失.(2)MSF能在土壤溶液中完全降解,养分的可利用率高.(3)MSF水解反应缓慢,性能较为稳定,便于存放和使用.

本文对春小麦喷施稀土十年定位试验的小麦籽粒，土壤中的稀土和放射性含量进行了分析，证明长期使用稀土后土壤，小麦籽粒中的稀土和放射性含量与对照样相比没有明显的区别，说明稀土农用不仅效益显著，而且是安全的。     

Inclusion Compounds — possibility of their combination and use in different branches of chemistry

Hofmann-type and related compounds, a natural zeolitic material of the clinoptilolite type, and cyclodextrins have been studied. Different products, useful in the separation of organic mixtures, used with fertilizers and insecticides in agrochemistry, perfumes, and in the detoxication of raw materials, have been prepared by combinations of the inclusion compounds studied. In the Hofmann-type compounds and cyclodextrins the original guest is substituted; in the zeolite the original sorbate, as well as some part of the zeolitic host is substituted. The physical mixtures of the starting materials differed from the products in their thermal, spectral and diffractographic characteristics. Field test results and other supporting evidence are added.
