The Effect Of Organic Manure On The Eggplant Yield And Quality

Vegetable products have confronted sharp competition since china joined WTO. While the quality is the main factor of price and limit of export. At present, china are confronting with adjusting structure , it is an important meaning to product vegetable that accord to the demand of international market.Applying organic manure has a long history in china. At the same time, applying organic manure is according with not only the demand of green food product in china and international organic food demand. Chicken and pig barnyard manure are rich in resources and have good fertilizer effect, which may be used widely in product. There are many study about the two kinds of fertilizer, which are studying on a decide point to applying fertilizer for many years or to comparing with each other about the two kinds of fertilizer, but since they have different effect and suit applying quantity, there are different deviation in result of appraising fertilizer.Eggplants which beings to Solanum MelongenaL, have been cultivated in china for 1000 years, which have the capacity to growing in fertilizer soil and to fertilizer-resisting. Eggplants contains much vitamin, protein, sugar, Ca and Fe, while vitamin P is the first place in fruit and Vegetable. Eggplants have been cultivated widely at present, which are no more than tomato and cucumber in china. Eggplant has been an important vegetable in domestic market and export products. There are seldom report about to applying organic manure to product high quality eggplant. By applying different chicken barnyard and pig barnyard , this experiment have appraised the growing effect of the two kinds of barnyard on eggplants.Applying fertilizer on eggplant will improve yield, growth and quality . This experiment have reached conclusion such as follows:1 applying organic manure may enhance eggplant yieldIn the scope of supposing applying fertilizer in this experiment, there areIVgood linear relations between the applying fertilizer quantity and eggplant yield. The relation of applying chicken barnyard and yield showed that they had achieved remarkable level ,such as y= 14.222+0.486x, and the interrelated coefficient r=0.9408, while the relation of applying pig barnyard and yield showed that they had achieved extreme remarkable level, such as y=13.896+0.5008x,and the interrelated coefficient r=0.9852.2 Organic manure may affect the form of eggplant yieldEggplant yield will show the relation of the number of bearing fruit and single fruit weight directly, and the positive interrelated coefficient between bearing fruit number and yield "r" equals 0.951(r=0.951), while the interrelations between single fruit weight and yield is not remarkable, which illustrate that the contributing ratio of bearing fruit number will surpass the contributing ratio of single fruit weight. At the same time , the effect of applying pig barnyard manure to enhancing yield by bearing fruit number will have notable results than applying chicken fertilizer .Although urea may improve eggplant' single fruit weight in effect , the yield will lead to decreasing for the numbers of bearing fruit reducing.3 Organic manure may retard the harm of verticillium wilt on eggplant Diseases index and infected plant rate both have different degreereducing after applying barnyard manure , while the state of illness is slight after medium level applying, fertilizer. Although low level applying fertilizer will also have the effect of verticillium wilt -resisting., it lowers the medium level .The negative interrelations between diseases index and yield "r" equals -0.842(r=0.842).For the routine applying urea area and the untreatment area have high diseases incidence , the early ageing or dying of plant will lead to reduction of output .4 Organic manure may improve agronomy property of eggplant Barnyard manure may enhance leaf area square . When applying pigbarnyard manure comes to 10 t/667m2, photosynthesis horizontal leaf areasquare may maximize. While routi...
