Effects of Microbial Fertilizer and Compound Feritlizer Mixed Application on Yield and Fruit Quality and Flowering and Fruit Setting of Following Year of Apple

In order to study the application effect of microbial fertilizer and compound fertilizer mixed application on microirrigation apple, three types of fertilizers were applied in spring which were urea（CK, 15 kg/plant）, microbial fertilizer（5.0 kg/plant）,microbial fertilizer and compound fertilizer mixed（each 2.5 kg/plant） to study the effect of different fertilizer treatments on yield, fruit quality, flowering and fruit setting of Xinshijie apple. The results showed that application of microbial fertilizer could increase the yield, fruit weight and fruit shape index, significantly increase the flowering rates and inflorescence fruit setting rate of following year, while reduce the fruit hardness and soluble solids content, and the effect of microbial fertilizer and compound fertilizer mixed application on increasing fruit weight and yield was higher than that of microbial fertilizer separate application, the effect of the two was not obvious in other aspects. Therefore, microbial fertilizer could be used instead of some chemical fertilizer and organic fertilizer in apple production to reach the aim of increasing yield and efficiency, and the effect of microbial fertilizer and compound fertilizer mixed application was best.

A Preliminary Investigation of Low Yield Reason of Camellia oleifera in Dehong Prefecture

[Objective] The paper was to preliminarily investigate the low yield reason of Camellia oleifera caused by fruit and flower dropping in Dehong prefecture. [Method]Pollen viability of C. oleifera was determined using I-KI and TTC （2,3,5-triphenyl tetrazolium chloride） method, the germination rate of pollen was determined by in vitro culture method, the pollen tube growth was observed by the fluorescent microscope through aniline blue dyeing, and the effects of different pollination methods on fruit setting rate of C. oleifera was analyzed. [Results] The pollen viability and the quantity of pollen tube of C. oleifera with good fruiting were significantly higher than the plants with poor fruiting, but their pollen germination rate had no significant differences; cross pollination was conducive to fruiting setting of C. oleifera. [Conclusion] The growth and development condition of C. oleifera pollen had important effect on the yield of C. oleifera in Dehong prefecture.
