Fromthese facts,It could be deduced that 8 to 14 pairs of chromosomes possessed a certaindegree of hetorology,which was directly groved to be hybrid origin of P.tomentosaaccording to the good chromosome homology and fertility of P.bolleana and thehybrids of P.tomentosa×P.bolleana,it could be further deduced that the original parentsof P.tomentosa involved probably P.bolleana or P.alba.

从终变期、中期I的染色体构型看，有数目不等的联会程度较差的单价体和棒状二价体出现，在后期I，甚至末期I亦可见到含落后染色体分裂相的细胞，由此推断可能有8~14对染色体表现出一定程度的异源性，鉴于新疆杨以及毛白杨与新疆杨杂交产生的杂种毛新杨的染色体同源性较强、育性较好等现象，进一步推断毛白杨起源亲本可能包括新疆杨或银白杨。

Soil Ca2+ content increased by 0.749mmol/kg, Mg2+ content increased by 0.169mmol/kg, the Na++ K+ content dropped by 9.52mmol?kg, SO42- increased by 0.091mmol?kg, Cl- reduced by 1.727mmol?kg, the HCO3- content in the soil assumed the obvious dropping tendency, it might be explained that the advancement of HCO3- has transformed into CO32- in the oasis, and has formed precipitation with two price calcium magnesium heteropolar ,then fix in the soil layer.

The Ca2+ salt solution as a new regenerant was presented in this paper. The influences of the calcium salt proportioning, temperature, dosage and flow rate on anion exchange fiber regeneration were studied. High regeneration can be obtained with 0.5 mol/L CaCl2+8 g/L CaO+6.5 °Bx sucrose solution at 70～80 ℃, the dosage of the Ca2+ salt solution was about half of the raw decoloring syrup, the regenerant flow rate should be lower than that of the raw decoloring syrup. It was shown that stable decolorization rate and lower decline in exchange capacity could be achieved with the new regenerant. It performed more effectively than the traditional sodium salt regenerant with less discharge of waste water.
