The results showed that soil type had significant effects on the root morphology and nodule traits of test varieties. In alfisol, the root dry mass, root length, and root surface area of test varieties were greater at the fifth trifoliolate stage and bloom-beginning stages while smaller after seed-beginning stage, compared with those in mollisol, and the average root diameter after seed-beginning stage was higher in alfisol than that in mollisol. Soil type did not affect root-shoot ratio. The nodule number after seed-beginning stage was much smaller in alfisol than in mollisol, while the nodule fresh mass and the mass per nodule were in adverse.

The study was focused on the amount of available water in soil, hydraulic conductivity in soil-root system from different root zones, sap flow from root to stem, compensatory effect of root water uptake, the fruit growth and physiological attibutes, evaporation and transipiration, and plant water use efficiency. Experiment plants involved apple tree, grape, peach, etc. Fruit trees were irrigated in both half root zones or water was continuously supplied to the one-half and the other half kept dry(fixed partial rootzone irrigation, F), or water was alternatively supplied to two halves (alternative partial rootzone irrigation, A).

Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现"低促高抑"的规律，且茎叶浸提液作用效应大于根系浸提液。

The author thinks that the main mind problems in the process of research are the followings: one is to tail after the western psychological mainstream and despising transpersonal psychology, the root of which is inferiority; one is to comply with the obsolete so-called scientific methods inflexibly, the root of which is timidity; one is to be wild about introducing our culture to the west without in-depth research , the root of which is speculation; one is to be deliberately mystifying, such as one-sided emphasis on "insight" and unspeakable, the root of which is conceit; one is to try to create our local psychology impatiently but being restricted to a designated area, the root of which is anxiety.

我认为中国的心理学家在研究的心态中存在的问题主要有：追随西方心理学"主流"，鄙视超个人心理学，心态的根源是自卑。严格依从旧的"科学"方法，心态的根源是胆怯。热衷向西方人介绍，但是不深入研究，心态的根源是投机。故做玄虚，片面强调"悟"、"不可言说"等，心态的根源是自负。急切于建立本土心理学，但是画地为牢，心态的根源是焦虑。
