Branch Drawing Influence on Growth and Fruit Setting for Young Tree of Pear Varieties.
Dai Wensheng, Wang BaiPo, Qian Yincai, Ding Xiaozhang
1996, 13(2): 123-129.
Abstract:
For young tree of pear,branch drawing helps tree crown to expand,leaf curtain forming to speed up,long branch number to grow,branch length to reduce,and ratio of fruit and branch to increase.After branch drawing,cultivated varieties increase in general leaf area,decrease in light intensity inside tree crown and photosynthesis intensity,and increase in inflorescence and fruit setting.Cultivated varieties differ greatly in branch drawing reaction。Yellow flower varieties,In inflorescence,are the most remarkable,but No.4 that is strong and erect branch is bad;in number of fruit setting,No.7 and No.17 that are difficult in flower bud forming are the most remarkable,but yelower flower varieties that are easily in flower bud forming are bed.Major cultivated varieties have effect in flowering in the first year after branch drawing,with effectiveness for a given period of time.
Photosynthetic Characters of Seven New Tea Plant Varieties under different soil Moisture Levels.
Luo Yaoping, Pan Gensheng
1996, 13(2): 130-135.
Abstract:
Under the conditions of high,medium and low moisture,Photosynthetic characters of seven tea Plant varieties including six new varieties of Zhenong121,Pingyun,Longjingehangye,Zhenong113,Juhuachun,Biyun and one national improved tea variety Fuding-dabaicha were studied.The results indieated that:1.Under different soil moisture levels,the net Photosynthesis rate(Pn),transpiration rate(Tr)and stoamtal conduetacne(Gs)values of Zhenong121,Zhenong113 were high with excellent photosynthetic charaeters;Under high soil moisture level,photosynthetic characters of Pingyun and Longjingchangye were quite good:Under medium soil moisture level,Photosynthetic characters of Pingyun and Biyun were quite good;Under lower soil moisture level,photosynthetic characters of Fdingdabaicha were quite good.2.Tr was significant correlated with Gs.Under the high and lower soil moisturem levels,Pn was nagative correlated with Ci (carbon dioxide concentration among laeunae):Under medium soil moisture level,Tr was significant correlated withCi,and Gs was signifieont correlated with Pn:Tr was significant correlated with Pn,and Gs was highly significant correlated with Ci.
Tree Bark:An Indicator of Air pollution and Precipitation Acidity
FanHoubao
1996, 13(2): 136-140.
Abstract:
The locating monitor of acidity and chemical components of rainfall,throughfall and stemflow was implemented for one year,and pH values and buffuring capacity were determined for bark samples of ten tree species in NanPing,Fujian.The acidification of tree barks closely related to the air Pollution.All tree bark samples in Xiqin Forest Farm showed more acidity and greater buffuring capacity against alkali than those in Experimental Forest of Fujian Forestry College.The acidified stemflow affected the soil acidity around the tree stem.Tree bark was recommended as a sensitive indicator of air pollution and precipitation acidity in Nanping.

1996, 13(2): 157-162.
Abstract:
Forest vegetables in Huzhou fall into 7 types,belonging to 62 famlies and 189 species.Local residents pick most species of them as food.only a few species are cultivated,such as Phyllosrachys,Toona sinensiss and Castanea mollissima,etc.Initial success has been achieved incultivation of Toona sinensis within plastic sheds and introduction of Lycium chinese.Starting periods of bamboo shoots on Phyllostachys propinqua forest land covered bamboo leaves,rice hull and bamboo leaves+rice hull are moved up for 64d,56d and 57d and shooting periods are prolonged for 47d,41d and 42d respectively。
