The pH value in soil was significantly increased in litter aqueous extract of four decomposition stages. The NH+4-N concentration was significantly decreased in soil amended with litter aqueous extract of 10-day decomposition which promoted the growth of Aerobic azotobacter and Ammonifier but inhibited the growth of Aerobic cellulose-decomposer. Available phosphorus concentration was significantly increased and phenolic acid content was significantly decreased in soil amended with litter aqueous extract of 60-day decomposition which inhibited the growth of Aerobic azotobacter but promoted the growth of Aerobic cellulose-decomposer.

In the computer simulation aspect, following work has been down:At first, the Wolfgang Schreiner's model is employed and extended to a new computer arteriole optimal growing model. Many new algorithms are described, such as signal tracing, resistance calculating, resistance balancing and flow balancing. With these algorithms and methods, the arteriole networks can be grown successfully on microcomputer.Secondly, a growing-network ordering method, which is called auto-centripetal ordering method of the growing networks, can be employed to order the growing networks to calculate the average parameters of the networks in level series.

They distribute in subtropics of China. Five species of subgenus Brachypelalum are the most primitive grou p of Paphiopedilum in China and four of them distributed in the limeston e re gions of Eastsouth Yunnan. Most species of Paphiopedilum distribute in this area,too.

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。

同等氮量下，基肥全部用白三叶的处理，生菜的株高、叶宽、叶片数、地上部鲜重和地下部鲜重均显著高于对照，基肥减少50％白三叶用量的处理在追肥前生菜的生长与对照相比无显著差异，追施复合肥后生菜生长显著优于对照，株高、叶宽和地上部鲜重显著优于基肥全部用白三叶的处理。

Soybean planted in the yellow brown soil, althongh they had big difference in nodule numbers caused by different inoculation methods, there were no difference in the fresh shoot weight because of the poor nutritional conditions. Soybean planted in the brown soil, the difference between different inoculations and fresh shoot weight were obviously because of the balance nutritional conditions. Although there were big difference in nodule numbers when soybean were planted in the peat, there were no difference in the fresh shoot weight, this might be caused by peat, the peat were not a natural soil type and the nutritional conditions might be unbalance.

分期采样的结果表明，黄棕壤中栽种的大豆，虽然接种根瘤菌对结瘤作用有较大的影响，但由于黄棕壤的肥力状况欠佳，而对豆科植物地上部分生长的影响未显出作用；棕壤土中栽种的豆科植物，接种根瘤菌在结瘤方面和植物地上部分生长方面，由于土壤肥力状况较为平衡，均表现出明显的效果；草炭土中生长的豆科植物在结瘤方面虽然表现出较大差异，但由于这种土壤的肥力状况不适于豆科植物的生长，而使地上部的生长也未形成统计上的差异。
