Interaction Between Tillering Onion And Biochar Addition In Greenhouse Tomato

This study interplanting tillering onion and add biochar tomatoes as the research target,aims to address the tomato interplanting tillering Onions and add biochar double factors on the yield and quality of tomato interaction effect.It provides guidance and Suggestions for tomato intercropping and biochar cultivation in actual agricultural production.This experiment in planting soil environment,continuous cropping with interplanting tillering Onions and adding different amount of biochar tomatoes as the research object,analyzing different processing tomato rhizosphere ecological environment,photosynthetic rate,plant growth and quality of tomato,the change of production.associated tillering onion and tomato varieties glorious 101biochar double factors as the research object,have eight processing:1,interplanting tillering onion method,from the tomato root 8 cm,4 semicircle is planted at the tillering Onions,planting distance of 5 cm.2.The biochar is mixed evenly according to the experimental dosage.For each treatment,the area was 4.6m by 7.7m,covering the black mulch with drip irrigation under the film.The growth index,photosynthetic index and quality determination were determined after30d,60d and 90d respectively.The soil ecological environment was measured by 5-point sampling method.1.Concomitant and biochar treatment can promote the growth and development of tomato and increase the yield of tomato.CK1 yield of T1,T2 and T3 increased by 3.61%⁶.26%compared with that of tomato,while that of T4,T5 and T6 increased by 6.23%⁹.17%compared with that of tomato.T6 improved significantly.The results show that tomato associated tillering onion and added biochar are better than tomato single cropping,which is of great significance to guide the actual production.2.The Associated and biochar treatment can improve the quality of tomato fruit to varying degrees,and T4 can significantly improve the quality of vitamin C in tomato fruit.The soluble sugar and soluble acid of tomato fruit increased with the increase of biochar,and the improvement of T6 treatment was significant.The content of soluble protein in tomato was not changed much.3.In the middle of tomato growth,associated tillering and biochar addition 20t·hm^-2?T6?significantly increased the content of chlorophyll and photosynthetic rate of tomato.4.Tomato associated growth and biochar increased the content of quick available nutrients in tomato rhizosphere soil.The soil pH was increased in different degrees,and the soil EC value of accompanying CK2 was significantly higher than that of other treatments at the later stage of tomato growth.In the soil alkali-nitrogen solution,the improvement effect of T5 is obviously better than other treatments.The content of available phosphorus and available potassium can be increased in different degree with the application of biochar.5.Tomato associated tillering Onions and adding biochar?T4,T5,T6?increased the activity of tomato rhizosphere soil enzyme to different degrees.The activities of urease,phosphatase and dehydrogenase in tomato rhizosphere soil were significantly increased by T4,T5 and T6,among which the best results were obtained from the co-generation and addition of biochar 20t·hm^-2?T6?.The associated and biochar improved the flavor and quality of tomato fruit and increased the yield of tomato.Associated and added biochar 5t·hm^-2?T4?significantly increased the vitamin C content of tomato.Associated tillering onion significantly increased chlorophyll content and photosynthetic rate.Associated and biochar treatment increased the content of soil available nutrients,increased soil enzyme activity,and improved soil ecological environment.
