The results showed that 1518kg farmyard manure and 59.9kg chemical fertilizer, equal to 38kg N, P and K pure nutrient, were applied per unit area (667m2) of arable land,and that the nutrient ratio of farmyard manure and chemical fertilizer was 4.9∶5.1 (N∶P2O5∶K2O=1∶0.4∶0.62), and that the total complex grain output per year and the complex output value were 479.6kg and 804.47yuan per 667m2 respectively, and that the manure cost and the pure income from manuring were 148.25 yuan and 716.22 yuan per 667m2 respsctively, and that 12.6kg grain output could be gotten averagely from 1kg nutrient input The main factors affected the manuring effect were topography, cropping systems and crops kinds and manuring quantity from a peasant household as well effected the soil fertility significantly.

结果：平均每667m2耕地投入农家肥1 518 kg，化肥59.9 kg，折氮磷钾纯养分38 kg，农家肥与化肥养分比为4.9∶5.1，N∶P2O5∶K2O=1∶0.4∶0.62，全年粮食复合单产479.6 kg/667m2，复合产值864.47元，肥料成本148.25元/667m2，肥料纯收入716.22元，肥料产投比值5.9，投入1 kg养分产粮12.6 kg。影响投肥效应的主要因素为地势、耕制和作物。农户投肥数量对土壤肥力影响较大。

Cantly greater numbers of living larvae were found in sugar maple than in the other tree species; however,more were found in red oak and fewer in green ash than expected,considering relative numbers of oviposition sites. After 90 d,mean mass of living larvae did not differ signi?cantly among tree species.

然而，考虑到产卵点的相关数量，我们在红橡树上发现的活的幼虫的量要比预料的多，而在白蜡树上发现的幼虫的量则没有预料的多。90天后，在这些树种上平均幼虫总量已经没有显著的差异了。

The twig production of different clones is different, from 5.5 twigs per month to 14.8 twigs per month. The rooting rate, root number and root length change regularly as the concentration of IBA goes up from 0.05 to 2.00 mg/L. At the concentration of 0.05 mg/L ppm IBA, rooting rate and root length are the highest. Cutting substrate also has eminent effect on rooting rate and survival rate, 50% peat plus 50% sub-top soil is the best substrate. The survival rate differs greatly among clones, from 56.7% to 90.0%. Rooting rate and survival rate change regularly as season changes. The rooting rate of May and June is middle, that of July and August is high and that of September and October drops rapidly. The survival rate is low in May, September and October and high in June, July and August.

结果表明：不同无性系的萌条数量有显著差异，高的达14.8条／月，低的5.5条／月，平均9.1条／月，从0.05~2.00 mg/L，随着IBA浓度的提离，生根率、根条数、总根长等生根指标均呈现有规律的变化；综合考虑各种生根指标，以IBA0.05 mg/L为最佳生根激素处理，扦插介质对柚木插穗生根有显著的影响，以泥炭土＋黄心土按1：1混合为最佳扦插介质；不同无性系的扦插成活率不同，从56.7%至90.0%，变动幅度大，随扦插季节变化，生根率和成活率均呈现有规律的变化，5~6月份的生根率中等，7~8月最高，9~10月份迅速下降，成活率随季节的变化也是两头低、中间高，6~8月的成活率最高，大于93%。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
