The Study Of Four Kinds Of New Fertilizers Application On The Tomato And Cucumber In The Solar Greenhouse

The vegetable planting in greenhouse in northern China are characterized by low temperature and weak light.There are some unreasonable factors in the use of fertilizer,which result in serious loss of nitrogen fertilizer,low fertilizer utilization rate,and the natural resource efficiency of vegetable production potential and facilities soil can not be brought into play.In recent years,related reports on new fertilizers have been continuously reported,but few studies have been done on vegetables in solar greenhouse.In this paper,the liaoyuanduoli tomato and cucumber winners as tested crops,take pot experiment application foliar and root irrigation two fertilization effects of four kinds of new type of fertilizer is widely used on the market for crop growth,yield and quality of Tomato in solar greenhouse,screening out the new kind of fertilizer and suitable for cucumber the optimum concentration and the number of.The aim is to provide theoretical basis and practical guidance for high yield and high yield and high efficiency of crop fertilization.The effects of greenhouse cucumber tomato photosynthesis index,yield and fruit quality were analyzed.1.The results of foliar spraying of New Cucumber fertilizer showed that every 7 days of foliar application of humic acid and water soluble fertilizer with 800 times of liquid spraying was the best.It significantly promoted the growth of cucumber plants,tall plants,thick stems,and enhanced root activity.The photosynthesis and chlorophyll content and proline(Pro)content increased,and the MDA content and the stress tolerance of cucumber leaves were decreased.Cucumber yield,fruit Vc,soluble sugar,soluble protein and free amino acid increased significantly,and the quality of products improved significantly.2.The root application of New Cucumber fertilizer showed that the treatment of seaweed fertilizer with 1000 times of spraying at the interval of 10 days had the best treatment.The plants were tall and sturdy,and the root activity increased.The photosynthesis and chlorophyll content and proline(Pro)content increased,and the MDA content and the stress tolerance of cucumber leaves were decreased.Cucumber yield,fruit Vc,soluble sugar,soluble protein and free amino acid increased significantly,and the quality of products improved significantly.3.The spraying results of the new tomato fertilizer leaf surface showed that 500 times the root of 7 days was best treated with humic acid water soluble fertilizer,which promoted the growth of tomato,and had a significant influence on the photosynthetic capacity of tomato.Chlorophyll content is high,leaf photosynthetic rate is high,high photosynthetic efficiency is long,and photosynthetic capacity is strong,which is conducive to the production and accumulation of assimilation products.Significantly increased tomato yield significantly increased tomato yield and fruit quality,and tomato fruit Vc and soluble sugar increased significantly.4.,The root application of tomato new fertilizer showed that the treatment of seaweed fertilizer with 1000 times of spraying every 7 days was the best.It promoted tomato growth and had a significant effect on Tomato photosynthetic capacity.Chlorophyll content is high,leaf photosynthetic rate is high,high photosynthetic efficiency is long,and photosynthetic capacity is strong,which is conducive to the production and accumulation of assimilation products.Significantly increased tomato yield significantly increased tomato yield and fruit quality,and tomato fruit Vc and soluble sugar increased significantly.
