The Influence Of Self-Made Anti-Transpiration Foliar Fertilizer To Seedling On Growing And Physiological Indexes

In arid and semi-arid conditions, plants will lost a lot of water because of transpiration, which lead to deficit or even dehydration. On the basis of research of the developing history and current situation of anti-transpirant and foliar fertilizer home and aboard, a novel anti-transpiration foliar fertilizer was developed by analyzing and modifying the ratio of anti-transpirants and foliar fertilizer. The four-factor-three-level orthogonal experiment design was adopted to investigated the influence of foliar fertilization on seedling growing indexes, physiological indexes and some other index effects of Primus armeniaca and Salix matsudana. Under different soil moisturing conditions, Prunus armeniaca and Salix matsudana were treated with different concentration ratio of different foliar fertilization. The growing indexes including new shoots height, new shoots diameter, biomass and the physiological indexes including chlorophyll content, photosynthetic rate, transpiration rate, water use efficiency were measured and analyzed in order to select an optimal combination of anti-transpiration foliar fertilizer and soil moisture for Prunus armeniaca and Salix matsudana., This study aiming at providing theoretic and technical support for vegetation restoration and ecological building in arid and semiarid areas of loess plateau.Results are as follows:(1) Both self-made anti-transpiration foliar fertilizer and market fertilizer improved new shoots height、new shoots diameter and biomass of Prunus armeniaca and Salix matsudana. For Prunus armeniaca, the optimal treatment is self-made①with900times diluted and15%soil moisture. The best formula for Salix matsudana is self-made①with900times diluted and20%soil moisture.(2) Both kinds of self-made anti-transpiration foliar fertilizer and market fertilizer have positive effects on chlorophyll content,photosynthetic rate,transpiration rate, water use efficiency and leaf RWC of Prunus armeniacci and Salix matsudana in varying degrees. The best formula for Primus armeniac physiological indicator is self-made①with900times diluted and15%soil moisture. And the best formula for Salix matsudana physiological indicator is self-made①with900times diluted and10%soil moisture or20%soil moisture.(3) Taking all indicators available into consideration, we could rank the factors as fertilizer, spraying concentration and soil moisture. The optimal combination to improve general traits of Primus armeniaaca is A1B2C2.3, i.e. the best is900times dilution of the concentration between the self-made fertilizers①on soil water content of15%-20%. The most prominent combination to improve general trais of Salix matsudana is A1B2C3,that is,900times dilution of the concentration between the self-made fertilizers①on soil water content of20%.
